Product details

The STPS30SM60ST is a 30 A average rectified, 60 V reverse-voltage Schottky diode in a through-hole TO-220-3 package. Schottky technology gives it a fast recovery time (≤500 ns above 200 mA) and a low forward voltage drop of 615 mV at the full 30 A rating — both critical for high-efficiency rectification in switch-mode power supply output stages, OR-ing diodes, and freewheeling circuits where lower Vf directly reduces conduction loss and heatsink size.

The TO-220-3 through-hole package is a standard power package designed for bolt-down or clip-on heatsink attachment. Reverse leakage at 60 V is 135 µA — a figure to include in standby-loss calculations for continuously biased OR-ing applications.

Frequently asked questions

Where can I buy STPS30SM60ST?

STPS30SM60ST is obsolete from STMicroelectronics.

What is the replacement for STPS30SM60ST?

For a pin-compatible alternative, review the STPS30 family of 30 A Schottky rectifiers in TO-220 — parametric differences in Vf, leakage, or voltage rating will determine the best fit for your circuit. Sourcing through independent distribution can also supply the original part against an RFQ.
