SSDI Introduces New HiRel Power Hybrid Product Line for Military / Aerospace Applications
March 14, 2017

Solid State Devices, Inc. (SSDI) aims to fill the needs of military and aerospace contractors with its new HiRel Power Hybrid product line. Over the past 50 years, SSDI has built several power hybrid devices based on source control drawings, but now those will be complemented by standard catalog devices. With its reputation for high reliability discretes, assemblies, and power modules, the interest in SSDI’s hybrid capabilities has intensified with its customers’ concerns with their current sources. Whether a replacement part is needed to overcome obsolescence issues or unique part is needed for a new design, SSDI’s technical experts have a proven track record of delivering application specific package / die combinations to meet the most rigorous customer requirements. The initial offerings are half-bridge hermetic power hybrids but will soon be followed by other families such as DC-DC converters.

Half-Bridge, N-Channel MOSFET HiRel Power Hybrids Family
SSDI is proud to announce three new half-bridge, N-Channel MOSFET Power Hybrids, the SPH3270FP, SPH12100FP, and SPH24100FP. These hermetic devices share many key features and are ideal for high reliability applications such as motor controls, inverters, converters, robotics, etc. The following table highlights some of the key characteristics and electrical parameters (click here or on the part number for data sheets):

The low on-resistance ratings of these devices are a key advantage, which translates into high efficiency, fast switching capabilities with lower conduction losses and cooler operation. These characteristics can potentially lower costs by reducing the number of components and heat-sinking requirements needed. In addition to the performance benefits, the high reliability of these hybrid products is exhibited by the rugged poly-Si gate, high single pulse avalanche energy rating, voltage rating, and hermetically sealed isolated packaging (flat pack – 12 pin package). Class H and K Level screening based on MIL-PRF-38534 are available.

SSDI HiRel Power Hybrid Capabilities
Much like SSDI’s other standard products, this initial hybrid family only provides a glimpse of the capabilities available to customers. Additional requirements such as built-in Zener diode protection, gate resistor, built-in isolated / non-isolated gate drivers and anti-parallel diode for faster switching as well as other modifications can be addressed by SSDI’s in-house engineering and manufacturing team. SSDI can also provide package or lead modifications and die selection / matching for optimal performance over the full operating temperature range. The following table highlights SSDI’s hybrid product capabilities:
