Its 5 ns reverse recovery time and 7 pF junction capacitance at 1 V reverse bias make it suited for fast-switching low-current applications such as polarity protection, clamping, and high-speed signal rectification in mixed-signal or RF bias circuits. ## Forward drop, leakage, and the operating window Reverse leakage is specified at 500 nA maximum at 25 V reverse bias — 83 % of the 30 V Vr(max) rating — confirming the barrier quality holds near the voltage ceiling; leakage doubles roughly every 10 °C above 25 °C junction, so a design running at 85 °C ambient should budget 4-8 µA leakage per diode.","metaTitle":"BAT42 Schottky Diode, 30 V, 200 mA, DO-35, 5 ns trr","metaDescription":"BAT42 Schottky diode: 30 V reverse, 200 mA forward, 1 V Vf at 200 mA, 5 ns trr, 7 pF capacitance.
