What this Schottky module is built for
The STPS24045TV is a dual Schottky diode module from STMicroelectronics, packing two independent 120 A diodes with a 45 V reverse voltage rating into a single ISOTOP package. Each diode delivers a forward voltage of 670 mV at 120 A — low enough to keep conduction losses manageable in high-current, low-voltage circuits like output OR-ing, battery-charger rectifiers, plating supplies, and welding power stages.
Field-swappable package
Chassis-mount ISOTOP with screw terminals means no soldering iron needed. A socket wrench and a torque driver are all you need to swap this module on site — no lab bench, no hot-air station. The two independent diodes let you wire a center-tapped full-wave rectifier from one package, saving panel space and bus-bar work.
Thermal and leakage reality
Junction temperature maxes at 150 °C, and reverse leakage hits 2 mA at 45 V. That leakage is typical for a 120 A Schottky at full blocking voltage — factor it into your standby-loss budget if the diode sees sustained reverse bias at elevated temperatures. The 670 mV forward drop at 120 A is the figure to use for junction-temperature rise calculations under full load.
ROHS3 compliant. No official second source listed, but the ISOTOP footprint is common across ST's Schottky module family — the STPS24045TV is the 45 V / 120 A variant.
