It is built for low-voltage DC rails — think 5 V, 12 V, or 15 V supplies — where its 620 mV forward drop at 1 A keeps conduction losses manageable and its 30 pF junction capacitance supports fast switching without significant stored-charge tail. ## Forward drop and thermal budget — the real limit At 1 A forward current the Vf is 620 mV max, which puts 620 mW of dissipation into the SOD-323 body. The junction is rated to 150 °C maximum, so the PCB copper area under the cathode tab is what sets the real current ceiling — on a standard FR4 board with minimal copper, derate to about 0.6 A to stay below 125 °C junction. Reverse leakage at 15 V is 12 µA typical — low enough for most low-power bias and OR-ing applications, but it climbs exponentially with temperature. At 125 °C junction expect leakage to dominate the thermal budget if the diode is lightly loaded. ## Active production — no obsolescence pressure ROHS3 compliant.","metaTitle":"STMicroelectronics BAT20JFILM Schottky Diode, 23 V, 1 A","metaDescription":"ST BAT20JFILM Schottky diode: 23 V reverse, 1 A forward, 620 mV Vf, 30 pF capacitance.
