Dual Schottky in D²PAK — 15 A per leg at 150 V
The STPS30150CG is a dual Schottky rectifier from STMicroelectronics, pairing two 15 A diodes in a common-cathode configuration within a single D²PAK (TO-263-3) surface-mount package. It is rated for a maximum DC reverse voltage of 150 V and delivers an average rectified current of 15 A per diode. The forward voltage drop is specified at 920 mV maximum at 15 A, and the junction can operate up to 175°C, giving the part a wide thermal margin in high-current rectification and OR-ing applications.
At 15 A average per diode, the STPS30150CG suits output rectification in switch-mode power supplies and DC-DC converters where the total load splits across two paralleled Schottkys in a common-cathode pair. The 150 V reverse voltage covers 48 V and 72 V bus rails with derating headroom. The 920 mV forward drop at 15 A is typical for a 150 V-class Schottky at this current density — expect higher Vf at elevated junction temperature, which the 175°C rating accommodates for designs that push the thermal envelope. Reverse leakage is 6.5 µA at 150 V, a figure that rises with temperature; the common-cathode layout simplifies the PCB trace routing for the output rail.
