2018.01.30 - New Hermetic 5 Amp, 300 Volt Schottky with Extremely Small Footprint

5 Amp, 300 V Hermetic Schottkys

SSDI is proud to introduce the latest product offering in its hermetic 300 volt silicon Schottky product family, the SSR05300S.22 series. The SSR05300S.22 offers 5 amps of output current and a reverse voltage up to 300 volts, the highest voltage rating for hermetic silicon Schottkys in the industry. When SSDI was the first to achieve the 200 volt rating for hermetic silicon Schottkys, design engineers began upgrading 100 and 150 volt devices to increase guard band for spacecraft / satellite applications. In the same way, the SSR05300S.22 with its 300 volt rating will enhance reliability by offering the highest guard band for existing and new designs. These devices also offer a low forward voltage drop of 0.93 V (@ 5 Amps, 25°C) and low reverse leakage current of 5 µA typical (@ 125°C).

The SSR05300S.22 is available in the SMD.22 surface mount package. With a footprint of only 0.157 in. x 0.227 in., low profile of 0.075 in. max, and low weight of 0.12 g typical, this high density package will allow designers to maximize board space and reduce weight, which is often critical for satellites, launch vehicles, manned spacecraft, and military aircraft.
