Its 530 mV typical forward voltage at 300 mA sets the conduction loss floor for low-voltage rail protection, OR-ing, and signal steering where every millivolt of drop matters. The 30 V reverse standoff covers 12 V and 24 V rails with margin, and the 5 µA leakage at that voltage keeps standby draw low in battery-powered equipment. ## Sub-500 ns recovery — not just a DC diode Rated for fast recovery under 500 ns at forward currents above 200 mA, this array handles moderate-speed switching — think flyback snubbers, charge-pump stages, or low-frequency rectification — not just static DC steering. The 300 mA average rectified current per diode is continuous, not surge; for pulsed loads, the thermal capacity of the SOT-323 is the limiter, not the silicon itself. ## SOT-323 dual series — two diodes, one footprint Two Schottky diodes in series inside a single SOT-323 saves board area and halves the pick-and-place count versus two discrete SOD-323s. The junction temperature ceiling is 150 °C, so derate the forward current if the ambient near the part exceeds 85–90 °C. Surface-mount rework is straightforward — the SOT-323 body is small enough that a hot-air pencil at 300 °C with fine tweezers lifts the part cleanly if you pre-tin the pads.","metaTitle":"STMicro BAT30SWFILM Schottky Diode Array, 30V, 300mA","metaDescription":"STMicro BAT30SWFILM dual series Schottky diode, 30V Vr, 300mA Io, 530mV Vf at 300mA, 5µA leakage, SOT-323.
