The forward voltage is 530 mV maximum at 300 mA, which keeps conduction losses low in low-voltage rail rectification and polarity protection circuits. ## Switching speed and reverse leakage Classified as a fast recovery diode with recovery time under 500 ns at forward current above 200 mA, the BAT30KFILM handles high-frequency switching in DC-DC converters and freewheeling diodes without excessive turn-off losses. Reverse leakage is 5 µA at 30 V, typical for a small-signal Schottky — expect leakage to rise with junction temperature, so budget derating in hot environments. ## Capacitance and junction temperature Junction capacitance is 22 pF at 0 V bias and 1 MHz, low enough to avoid signal degradation in RF detector or clamping applications. Maximum junction temperature is 150 °C, giving headroom for reflow soldering and moderate ambient heat.","metaTitle":"BAT30KFILM Schottky Diode, 30V 300mA, SOD-523","metaDescription":"STMicroelectronics BAT30KFILM Schottky diode: 30V reverse, 300mA forward, 530mV Vf at 300mA, SOD-523 package.
