Dual 10 A Schottky in a full-pack TO-220
Forward drop and thermal headroom
At 10 A forward current the maximum forward voltage is 770 mV — this sets the per-diode conduction loss at roughly 7.7 W at full load, before derating for junction temperature. The junction is rated to 175°C maximum, giving headroom for high-ambient environments such as motor drives, PFC stages, or output rectification in switch-mode supplies where the heatsink runs hot. Reverse leakage at 100 V is 4.5 µA typical — a low figure that keeps standby losses in check, though leakage rises with temperature and should be factored into the thermal budget above 100°C junction.
