Reverse leakage is 10 µA at 70 V; that leakage doubles with temperature, so budget headroom if the junction runs hot. Junction capacitance is 2 pF at 0 V bias, 1 MHz. That low capacitance suits this diode for high-speed clamping, ESD protection on data lines, or RF detector circuits where the parasitic load on the signal matters. ## SOD-523 rework — small, but workable The SOD-523 package is a two-terminal device with a cathode mark on the top. The pad pitch is about 0.8 mm — fine enough that tweezers and a steady hand are needed for placement, but the thermal mass is low so hot-air rework is straightforward. Use a fine tip iron (0.3 mm chisel) for hand soldering; the part will survive a 260 °C peak reflow profile per J-STD-020.","metaTitle":"BAS70KFILM Schottky Diode, 70 V, 70 mA, SOD-523","metaDescription":"BAS70KFILM Schottky diode: 70 V reverse voltage, 70 mA forward current, 1 V VF at 15 mA, 2 pF capacitance.
