Product details

The STMicroelectronics STPS20SM60SG-TR is a 20 A, 60 V Schottky rectifier in a surface-mount D2PAK (TO-263) package. The 630 mV forward voltage at 20 A keeps conduction losses manageable, and the fast recovery characteristic (under 500 ns) suits it for switching frequencies above 200 mA.

The 20 A average rectified current rating is the headline number, but it comes with a junction temperature ceiling of 150 °C. In a real board, the D2PAK tab must be soldered to a substantial copper pour — without that thermal path, the junction will exceed the limit well before 20 A continuous. The 85 µA reverse leakage at 60 V is a room-temperature figure; expect it to rise significantly at the 125 °C junction end of the operating range, which is normal for Schottky diodes and should be factored into the thermal budget for high-ambient designs.

Frequently asked questions

What is the replacement for STPS20SM60SG-TR?

For a new design, select a current-production 20 A, 60 V Schottky in the D2PAK package from the same or another manufacturer. For an existing BOM, source the original STPS20SM60SG-TR through independent distribution against an RFQ.

What are the specifications of STPS20SM60SG-TR?

It is a 20 A average rectified current, 60 V reverse voltage Schottky diode with a forward voltage of 630 mV at 20 A. Reverse leakage is 85 µA at 60 V. It is rated for a maximum junction temperature of 150 °C and comes in a surface-mount D2PAK (TO-263) package.

Can STPS20SM60SG-TR handle 20 A continuous?

Yes, the average rectified current rating is 20 A. However, achieving 20 A continuous requires proper heatsinking through the D2PAK tab to the PCB copper pour, as the junction temperature must stay at or below 150 °C.
