The forward voltage is specified at 310 mV maximum at 10 mA forward current — a low drop that suits rail protection, OR-ing, and low-voltage rectification in portable or space-constrained designs. ## Forward drop and leakage at temperature At 10 mA the maximum Vf is 310 mV, which keeps conduction losses low in signal-level or low-current paths. Reverse leakage is 50 µA at 30 V — typical for a small-signal Schottky in this voltage class. The operating junction temperature range is -30°C to 85°C, so the part is suited for consumer, portable, and indoor industrial environments where the ambient stays within that window.","metaTitle":"STMicroelectronics BAT30F4 Schottky Diode, 30V 300mA 0201","metaDescription":"STMicroelectronics BAT30F4 Schottky diode, 30 V reverse, 300 mA forward, 310 mV Vf at 10 mA. 0201 (0603 metric) package.
