100 V, 2 A Schottky for automotive power rails
The STPST2H100ZFY is an automotive-grade Schottky rectifier from STMicroelectronics, rated for 100 V reverse voltage and 2 A average forward current. Reverse leakage is 2.7 µA at 100 V, a figure that rises with junction temperature — budget derating above 125 °C.
Junction temperature and switching speed
The fast recovery characteristic — under 500 ns at > 200 mA — keeps reverse-recovery losses low in switching applications above 50 kHz.
Package and assembly fit
Housed in a SOD-123F surface-mount package, the part occupies a compact footprint on the PCB. The SOD-123F is a standard low-profile diode package with a small copper pad area — the thermal resistance to ambient depends on the board's copper pour under the cathode tab.
