Product details

SiC Schottky — zero recovery, no trade-off

The STPSC20065W is a 650 V, 20 A silicon-carbide Schottky diode from STMicroelectronics, part of the ECOPACK®2 series.

20 A average, 650 V blocking — sizing the power stage

Rated for 20 A average rectified current (Io) and 650 V DC reverse voltage (Vr). The forward drop maxes at 1.45 V at 20 A, so conduction loss at full load sits around 29 W — plan the heatsink accordingly. The DO-247 through-hole package handles the dissipation if you bolt it to a properly sized heatsink with good thermal interface.

175°C junction — margin for the hot end

That 175°C upper limit gives you headroom in a motor-drive cabinet or a sealed power supply where ambient can hit 85°C and the diode is the hottest component on the board. Reverse leakage is 300 µA at 650 V — a nonissue at rated voltage, but worth derating if you push the junction near the limit.

Frequently asked questions

What does 'No Recovery Time > 500mA (Io)' mean?

It means the diode exhibits zero reverse-recovery time (0 ns trr) when switching from a forward current greater than 500 mA. This is inherent to SiC Schottky technology — no stored charge, so no recovery tail. The practical benefit is dramatically lower switching losses and reduced EMI compared to a silicon ultrafast diode.
