Product details

170 V reverse blocking, 8 A per channel — what it handles

The STPS16170CB-TR is a dual Schottky rectifier from STMicroelectronics, wired as a common-cathode pair in a single DPAK (TO-252) package. Each diode is rated for 170 V reverse voltage and 8 A average rectified current, making this part a direct fit for output rectification in medium-voltage switchmode supplies, flyback diodes in DC-DC converters, and OR-ing applications in redundant power rails.

Forward drop and switching speed — conduction vs recovery trade-off

At 8 A forward current the maximum forward voltage is 920 mV — typical for a 170 V Schottky at this current density. The fast-recovery classification (≤ 500 ns, > 200 mA) means it switches faster than a standard pn rectifier but is not a hyper-fast SiC or GaN diode; expect clean turn-off in 100–200 kHz hard-switched converters without excessive ringing. Reverse leakage is 15 µA at the rated 170 V blocking voltage.

Frequently asked questions

What is the closest pin-compatible alternative to STPS16170CB-TR?

The part is an ST-only device in the STPS16170 family. For a dual common-cathode Schottky in DPAK with similar voltage and current ratings, evaluate the STPS16150CB (150 V variant) or the STPS20170C (20 A, larger package) — but confirm the pinout and footprint match your layout.

Is STPS16170CB-TR a common cathode diode?

Yes, the diode configuration is 1 pair common cathode — the two anodes are separate, the cathodes share the same tab connection. This is the standard wiring for output rectifier bridges and OR-ing circuits.
