Product details

The STPS30SM60D is a 60 V, 30 A Schottky barrier rectifier from STMicroelectronics in a TO-220AC through-hole package. It is designed for high-current, low-voltage rectification where the Schottky's low forward voltage drop and fast switching reduce conduction and recovery losses compared to a standard PN-junction diode.

STMicroelectronics lists the STPS30SM60D as Obsolete.

Reverse leakage and thermal budget at 60 V

Reverse leakage is specified at 135 µA at the 60 V maximum reverse voltage. In a hot environment, Schottky leakage rises exponentially with junction temperature — the 150 °C ceiling means the heatsink design must keep the die cool enough that leakage current does not dominate the thermal budget at light load.

Fast recovery — switching-speed context

The recovery time is rated ≤ 500 ns at forward current above 200 mA. This is a Schottky diode, so recovery is majority-carrier — the fast recovery spec confirms it handles the reverse-recovery transient cleanly in a 50–200 kHz switching power supply without the snap-off characteristic of an ultrafast PN diode.

Frequently asked questions

What is the replacement for STPS30SM60D?

A functionally similar Schottky in the same TO-220AC package with ≥ 30 A and ≥ 60 V ratings would need to be qualified against the BOM's forward voltage and leakage requirements — no direct cross-reference is listed here.

What are the specifications of STPS30SM60D?

It is a 60 V, 30 A Schottky rectifier with a 640 mV maximum forward voltage at 30 A, 135 µA reverse leakage at 60 V, fast recovery ≤ 500 ns, and a 150 °C maximum junction temperature. The package is TO-220AC through-hole.
