Product details

100 V, 10 A Schottky pair in a TO-220

The STPS20100CT is a dual Schottky rectifier from STMicroelectronics, housing two 100 V, 10 A diodes in a common-cathode configuration inside a single TO-220-3 through-hole package. Each diode is rated for 10 A average rectified current, and the pair shares the cathode pin — the typical application is a center-tapped full-wave rectifier or an OR-ing diode where both cathodes tie to the same output rail.

Forward drop and thermal budget at full load

At the full 20 A combined forward current (10 A per diode), the maximum forward voltage is 950 mV. Reverse leakage is 150 µA at the 100 V rated reverse voltage. At elevated junction temperatures leakage rises, so the thermal design should keep the die below 125°C in steady state to avoid runaway.

Frequently asked questions

Can I replace STPS20100CT with another Schottky diode?

A direct replacement needs the same TO-220-3 common-cathode pinout, 100 V reverse rating, and at least 10 A per diode. STMicroelectronics offers the STPS20100CT as the base number; other manufacturers' common-cathode TO-220 Schottkys at 100 V / 10 A are functionally equivalent but verify the forward drop and thermal resistance before substituting.
