2018.06.14 - SSDI Expands Hermetic, High Density 300 Volt Silicon Schottky Product Line

8 Amp, 300 Volt Hermetic Schottkys

SSDI has expanded its hermetic silicon Schottky product line with the release of the new SSR08250S.22 – SSR08300S.22 series. This series features a high voltage rating of 250 – 300 volts and an output current to 8 amps. SSDI’s 300 volt Schottky family offers the highest voltage rating available for hermetic silicon Schottkys in the industry. In contrast to lower voltage Schottkys, these 300 volt devices allow design engineers to achieve a higher voltage derating without sacrificing guard band and reducing reliability. These devices also offer a low forward voltage drop of 0.99 V typical (@ 8 Amps, 25°C) and low reverse leakage current of 0.1 µA typical (@ 25°C).

The SSR08300S.22 is available in the SMD.22 (S.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.

The SSR08300S.22 is the fifth offering in SSDI’s 300 volt Schottkys family, which offers an output current range of 5 amps to 40 amps. All of these lightweight devices feature high density, surface mount packages. The 40 amp centertap products are available in both hot case and isolated versions. SSDI specializes in developing the optimal die and package combination to best meet the electrical and mechanical requirements of each application.
