100V 30A Schottky in a PowerFlat 5x6
The STPS30H100DJF-TR is a 100V, 30A Schottky rectifier from ST, housed in an 8-PowerVDFN PowerFlat 5x6 surface-mount package. It is designed for high-efficiency power conversion where low forward voltage and fast switching are needed — the 840 mV typical Vf at 30A keeps conduction losses manageable, and the 6 µA reverse leakage at 100V helps standby power budgets.
Forward drop and thermal headroom
At 30A forward current the maximum forward voltage is 840 mV — this is the conduction loss the PCB copper and the PowerFlat exposed pad must sink. The 6 µA leakage at 100V reverse is specified at 25°C; expect leakage to rise with temperature, but the 150°C Tj ceiling allows the designer to push the thermal budget harder than a 125°C-rated Schottky.
