Active Schottky for 8 A rails — 490 mV Vf keeps losses in check
The STPS8L30B-TR is an STMicroelectronics Schottky rectifier rated for 30 V reverse and 8 A average forward current, in a DPAK surface-mount package. Its forward voltage drop is 490 mV maximum at 8 A — the figure that sets conduction loss and heatsink sizing in a power supply or polarity-protection circuit.
Parametric fit — leakage, speed, and junction temperature
Reverse leakage is 1 mA at the 30 V rated voltage — typical for a Schottky of this current class, but worth checking if the diode sits in a low-standby-power rail. The fast-recovery spec (≤500 ns, >200 mA) is standard for a Schottky; it handles switching frequencies in the tens of kHz without significant reverse-recovery losses. Maximum junction temperature is 150 °C.
