Product details

Dual Schottky in a TO-247 — what it delivers

The STPS80150CW is a dual Schottky rectifier from STMicroelectronics, with two 40 A diodes in a common-cathode configuration inside a single TO-247-3 through-hole package. The fast-recovery characteristic (≤ 500 ns) makes it suitable for line-frequency rectification, output OR-ing, and moderate-speed power supplies where Schottky's low Vf and fast switching reduce losses compared to ultrafast silicon diodes.

150 V blocking, 40 A per leg — the thermal and loss budget

At 150 V reverse and 150°C junction, reverse leakage is 30 µA typical — a figure that rises with temperature, so the thermal design must account for leakage-induced self-heating at high ambient. The common-cathode pair shares the same tab (pin 2), simplifying the PCB layout for a center-tapped secondary or a full-wave rectifier — the two anodes are independent, so each leg can be paralleled for higher current or used as separate rectifiers sharing a common return.

Frequently asked questions

Does STPS80150CW have a common cathode configuration?

Yes, the two Schottky diodes share a common cathode (pin 2 in the TO-247-3 package). The anodes are independent on pins 1 and 3, allowing use as a center-tapped full-wave rectifier or two separate rectifiers sharing a common return.

What is STPS80150CW's listed speed?

The datasheet specifies fast recovery ≤ 500 ns at > 200 mA forward current. This is a Schottky device, so recovery is majority-carrier — the 500 ns figure is a conservative upper bound; actual reverse recovery is typically much faster.
