100 V, 5 A Schottky in DPAK — what it covers
The STMicroelectronics STPS5H100B-TR is a Schottky rectifier diode rated for 100 V DC reverse voltage and 5 A average rectified current, housed in a surface-mount DPAK (TO-252) package. Its forward voltage is 730 mV at the full 5 A load, and the junction can run up to 175°C.
Forward drop and thermal budget
At 5 A the forward drop is 730 mV, which is typical for a 100 V Schottky in this current class. The DPAK's exposed tab on the bottom side needs a decent copper area or a heatsink to keep junction temperature under the 175°C absolute maximum.
Reverse leakage at the voltage limit
Reverse leakage is specified at 3.5 µA when the full 100 V is applied. That's a room-temperature typical; leakage doubles or triples as junction temperature climbs toward 175°C, which is normal for Schottky diodes. For designs that idle at high bus voltage in hot enclosures, factor in the leakage current when sizing the bias supply or calculating standby power.
