New TVS Offers Protection for Space Design
SSDI's new ST400A75S.22 series of transient voltage suppressors (TVS) has been designed in for a new Space program. Since the SMD.22 is a ceramic package, it performs more efficiently in the extreme temperature cycles of deep space environments than glass sleeve type packages.
New & Featured Products 2023
SSDI's New & Featured Products 2023 brochure is now available online. SSDI continually develops new, innovative products for Aerospace and Defense programs. When parts are no longer available or failing to meet electrical / mechanical requirements, SSDI can develop replacements with enhanced performance and various package options.
SSDI Develops HiRel Solutions for Competitor's Quality Issues
When a competitor’s part raised reliability concerns, SSDI’s customer needed a replacement to avoid similar issues for another space program. The application required a 200 V center tap Schottky in a doubler configuration, which was necessary for derating and reliability purposes. SSDI can resolve quality, performance, and supply issues that threaten to cause program delays.
SSDI Supports High Power / Voltage Devices with Legacy Packaging
Even though high reliability designs utilize the high power / voltage capabilities of stud mount and TO-can type packages, most semiconductor manufacturers are discontinuing support for these legacy packages. When a defense contractor could no longer procure a high voltage rectifier in the DO-5 package for their maritime defense application, SSDI was able to offer the SDR50120 as a drop-in replacement.
SSDI Delivers High Performance Patch for JANS2N3440UA Supply Issues
When a space program could no longer procure the JANS2N3440UA, SSDI offered a higher performance, drop-in replacement for the 1 A, 250 V NPN transistor. SSDI's SFT5010 series offers a higher voltage of 500 - 700 V and a lower leakage of 10 nA @ 400 V. In order to avoid re-design efforts for the customer, SSDI added the LCC4 package option to match the UA package footprint on the design.
New Zener & TVS Catalog
SSDI has released its new Zener & TVS catalog featuring new products and package options. Since SSDI has supplied many parts to SCDs, its capabilities extend far beyond the published listings. SSDI welcomes special requirements and also offers cross references to respond to supply and sustainment issues.
High Current Density Schottky for Aerospace & Defense
Aerospace engineers continue to turn to SSDI’s SED20HE100 Schottky for new, high reliability designs in military aircraft, launch vehicles, rovers, and satellites. The SEDPACK product line has amassed over 30 years of military and space flight heritage by delivering high performance in small, lightweight packages.
New RAD Tolerant P-FETs for Aerospace & Defense Applications
SSDI developed the SFL22P06S.5 to respond to a customer’s request for a 2N7624U3 replacement needed for a space application. SSDI can scale devices to meet specific program needs. For higher current requirements, SSDI offers the SFL40P06S.5, which delivers a continuous drain current of 40 A and drain-source voltage of 65 V. SSDI also released the SFL11P06S.22 to offer an SMD.22 option for designers that need to maximize board space.
SSDI Offers Alternatives to Glass Sleeve Diodes
SSDI can replace UR and US glass sleeve packages with either SMD.22 or SMD.22T packages for diode rectifiers, Schottky rectifiers, Zeners or TVS devices. The SMD.22T serves as a drop-in replacement for US packages and is available for all SMD.22 products even if not included on the data sheet. SSDI also offers diode solutions in the UR (SM), US (SMS), axial leaded, Sedpack, button tab, stud mount packages, and TO-X packages.
New, Hermetic TVS Offers High Peak Pulse Power
The ST10K100BT series delivers 10 kW of peak pulse power. These devices have a small footprint (0.45" W x 0.6" L max) and utilize a direct bond connection rather than wire bonds for more efficient power dissipation. The ST10K100BT was developed for a circuit breaker in a motor drive application for a space program.
SSDI Achieves QPL Certification for JANS1N8257US (6 A, 200 V Rectifiers)
On June 7, 2021, DLA Land and Maritime approved SSDI’s JANS1N8257US hyperfast rectifiers for QPL certification per MIL-PRF-19500/477. SSDI developed these 6 amp, 200 volt, 30 ns devices to provide higher performance than the 1N5811 within the smaller 1N5806 footprint.
High Voltage SiC Schottkys Developed for New Space Application
Mission critical applications for aerospace and defense demand higher performance and reliability products than general purpose devices found in distribution and primarily aimed at commercial applications. Space and defense contractors rely on SSDI to meet the electrical, mechanical, and screening requirements that exceed the capabilities of standard distribution parts. The 20 A, 1800 V SSR20C180 SiC Schottkys were developed to offer a single high voltage device to meet the derating target for new satellite applications.
New, Hermetic Silicon Schottkys Up to 150 Amps and 300 Volts
SSDI has expanded its Sedpack product line with the high current SED150LE100LL (150 A, 100 V) and SED100LE300 (100 A, 300 V). These high current, high voltage silicon Schottkys also offer low VF and IR for high efficiency performance in critical aerospace and defense applications.
SSDI Introduces New, High Power (8 amp, 300 - 400 volts) Replacement for 1N6626 - 1N6627
SSDI has released the new SDR8400 series of high density rectifiers. With similar dimensions as the 1N6627, the SDR8400 delivers 8 amps, which is more than three times the output current of the 1N6627.
SSDI Introduces New, High Power Schottky with Small Footprint
SSDI's new SSR10020S.22 - SSR10030S.22 series of hermetic Schottkys replaces 1N5817 and 1N5822 in high reliability applications. When compared to those devices, the SSR10030S.22 offers higher performance in output current (10 A), peak surge current (100 A), and maximum thermal resistance (3°C/W).
SSDI Adds GaN FET at Input Stage for Enhanced Radiation Tolerance
SSDI’s latest hermetic GaN FET device, SGR15E90M (15 A, 900 V), utilizes a GaN FET in the place of a silicon MOSFET at the input stage to provide enhanced radiation tolerance. The SGR15E90M’s cascode device structure consists of a high voltage depletion mode GaN FET at the output stage and a low voltage enhancement mode GaN FET at the input stage. With its enhanced radiation tolerance, the SGR15E90M is ideal for space applications (near Earth orbit and deep space) such as DC-DC / PoL converters, motor controllers, and switch mode power supplies.
SSDI Releases New, Hermetic Dual GaN FET
The SGF30E100Z8 consists of two GaN devices in one compact, hermetically sealed package, the 8 pin TO-254Z8. By replacing two devices with one SGF30E100Z8, design engineers can reduce the number of components needed, simplifying the design and assembly. In the half bridge configuration, it can be used in many high reliability space and defense applications such as synchronous buck or boost converters, H-bridge motor controllers, and single phase or three phase inverters.
SM720 TVS Array Highlights SSDI's Strengths
The SM720 electronic protection arrays feature a 6 kV ESD interface capability for HBM standards in accordance with MIL-STD-3015.7. They also provide overvoltage protection of +30 V (single ended voltage range). As the International Space Station approaches its 20th anniversary, SSDI continues to offer the SM720 as well as other hermetic products that have been supplied to this program.
SSDI Announces New SiC MOSFETs for Faster Switching and Higher Efficiency
The SFC85N90 are enhancement mode, N-channel SiC MOSFETs. These fast switching devices offer a very low RDS(on) of only 13 mΩ typ and 17 mΩ max (@ 50 A, 25°C). These radiation tolerant SiC MOSFETs can easily replace traditional silicon MOSFETs for an immediate boost in performance and efficiency.
SSDI Releases New Low Leakage Schottkys
Schottkys are often selected over conventional pn junction rectifiers due to fast switching speeds and a lower forward voltage drop. With an extremely low reverse leakage current of 0.4 µA (typical at 25°C, 100 V) and 10 µA (typical at 25°C, 150 V), the SSR4010S1 and SSR4015S1 offer fast switching performance without sacrificing efficiency.
