Product details

The STPS40SM100CR is a dual-Schottky rectifier from STMicroelectronics, pairing two 100 V, 20 A diodes in a common-cathode configuration inside a single TO-262-3 (I²Pak) through-hole package.

Conduction loss and thermal budget

At 20 A per diode, the 810 mV forward voltage sets the conduction loss floor: 16.2 W per diode at full load.

Obsolete — sourcing path

STMicroelectronics lists the STPS40SM100CR as obsolete.
