Trouble Finding the 1N5822? SSDI Delivers Rugged Alternative to 1N5822US
July 19, 2016

SSR5822 Series: Alternative to 1N5822US
SSDI's New Package Design Delivers Solution for Durability Concerns
and Supply Issues with the 1N5822US

Solid State Devices, Inc. (SSDI) is known for its ability to provide unique solutions to overcome issues related to electrical performance, mechanical specifications, reliability, obsolescence, and part availability. 
When a customer recently approached SSDI regarding their difficulty procuring the 1N5822US Schottky rectifier from other suppliers, SSDI engineers developed an alternative device to meet the needed electrical and mechanical specifications. Since the glass compression construction of the 1N5822US holds its die in place, a crack in the glass could cause a break in the solder contact or produce a short. The metallurgically bonded SSR5822S.22 alleviates these concerns and can be screened to specifically endure the stresses of the most demanding military and space applications.  
DROP-IN REPLACEMENT
Though the smaller, standard SMD.22 package can offer the same electrical performance, the customer desired a package with tabs that would serve as a direct "drop-in" replacement for the surface mount square tab package currently used in their design. While more and more suppliers are no longer manufacturing their own packaging, SSDI continues to offer package design, tooling, and testing capabilities to ensure that its modified or custom packaging options meet the customer's critical electrical and mechanical specifications. In the case of the SSR5822S.22T, the device not only matched the mechanical specifications of the 1N5822US, but also offered electrical improvements such as higher peak surge current and higher maximum operating / storage temperature ratings. TX, TXV, and S level screening are available. Screening is based on MIL-PRF-19500 with screening flows available upon request. 
THE NEXT STEP
With a tiny footprint of .157" x .227", SSDI engineers are developing new products in the SMD.22T package.  A 7 amp device, which translates into a higher efficiency version with lower VF ratings, as well as higher voltage versions up to 200 volts are currently being developed. 
SUSTAINMENT SUPPORT
While other suppliers run out of stock and delay new production activity for a particular product until demand has reached a certain level, SSDI can accommodate small volume orders. If not already archived among the over 10 million die in its expansive die bank, SSDI also purchases end of life die with full traceability so that parts can be supplied for the life of the program.
