100 V, 25 A per leg — what this dual Schottky delivers
Its forward voltage is 730 mV at 25 A — a figure that sets the conduction loss budget for the output stage of a high-current power supply or OR-ing circuit. The TO-220-3 through-hole package suits socketed or bolted-down mounting on a heatsink, typical in industrial power converters, battery chargers, and welding equipment where the pair shares the cathode rail.
Obsolete — sourcing through surplus distribution
For a BOM that calls out this exact order code, procurement now depends on the surplus and independent-distribution channel.
Fast recovery rating — switching context
Listed as Fast Recovery ≤500 ns at >200 mA, this Schottky recovers quickly enough for line-frequency and moderate-frequency rectification — think 50/60 Hz mains rectifiers or 100–200 kHz SMPS outputs where the diode's junction capacitance and reverse recovery are not the limiting factors. It is not a hyper-fast SiC or GaN companion; the 500 ns ceiling is a recovery class flag, not a switching-speed differentiator.
150°C junction limit and thermal design
Maximum junction temperature is 150°C. With 25 A per diode and 730 mV forward drop, each leg dissipates about 18 W at full rated current. The TO-220 case relies on a good thermal interface to a heatsink — without one, junction temperature exceeds the limit well below the 25 A rating. The 200 µA reverse leakage at 100 V is nominal at 25°C but climbs sharply with temperature, so derating for hot environments is mandatory.
