The 1N4148W is an SMD small signal switching diode designed for high-speed signal processing and switching applications. It features a maximum average forward current of 150 mA, a reverse voltage rating of 75 V, and a repetitive peak reverse voltage of 100 V, with an exceptionally fast reverse recovery time of less than 4 ns. The diode exhibits low junction capacitance of typically 2 pF and low leakage current, with forward voltage less than 0.855 V at 10 mA. Housed in a low-profile SOD-123F plastic package with a maximum junction temperature of 150°C, the 1N4148W is ideal for commercial-grade signal processing, high-speed switching circuits, and applications requiring fast transient response. Its RoHS and REACH compliance, combined with very high switching speed and minimal parasitic effects, make it a reliable choice for modern electronic designs.
