The STPS10170CB-TR is a dual Schottky rectifier from STMicroelectronics, configured as a common-cathode pair in a DPAK surface-mount package. The fast recovery characteristic — under 500 ns — suits it for high-frequency rectification in switch-mode power supplies, freewheeling diodes in DC-DC converters, and OR-ing diodes in redundant power architectures. The 175°C maximum junction temperature gives headroom for thermally constrained layouts in industrial or telecom environments.
Ratings that drive the BOM decision
The 170 V Vr rating sets the DC bus limit. The 5 A per diode is the average rectified current.
DPAK (TO-252-3) surface-mount with two leads plus the tab. The tab is the common cathode.
The base product number is STPS10170.
