Vishay Silicon Junction Switching Diode Single 150 mA 50 V Surface Mount SOD-123 1N4151WS-G3-08

Vishay 1N4151WS-G3-08 Silicon Junction Switching Diode is a high-performance single diode designed for industrial and electronic applications requiring fast switching and reliable operation up to 150 mA forward current and 50 V peak reverse voltage. Packaged in a low-profile SOD-123 surface mount case with a glass-passivated cavity-free junction, this diode delivers exceptional stability and low leakage current typically less than 0.2 μA.

The diode features a superectifier structure which enhances reliability and surge capacity. It supports a peak non-repetitive forward surge current of 2 A and has a low forward voltage drop max of 1 V, ensuring efficient power dissipation rated at 410 W. The switching speed is optimized, having a peak reverse recovery time of only 4 nanoseconds, making it ideal for high-frequency switching and rectification tasks.

Mechanical construction includes a DO-204AL glass epoxy body rated to UL 94 V-0 flammability standards. The leads are matte tin plated and solderable per J-STD-002 and JESD 22-B102 standards. The cathode is easily identified via the color band marking.

Typical applications include high voltage rectification of G2 grid in CRT and TV technology, and snubber circuits for camera flashes. Operating temperature withstands from -55°C to 150°C, suitable for automotive and commercial electronics environments.

This diode is RoHS compliant and manufactured in China. Package contains diode in tape packaging ready for automated PCB assembly, facilitating efficient production processes. Features a superectifier structure for high reliability and low leakage current.
