The Semtech M20 is a high-voltage single diode rectifier manufactured by Semtech Corporation. Housed in an axial (through‑hole) package, it is designed for standard recovery performance. The diode supports a peak reverse voltage of 2,000 V, an average forward current of 330 mA, and features a forward voltage drop of approximately 5 V @ 125 mA. With a reverse recovery time around 2 µs and excellent leakage characteristics (around 250 nA @ Vr), it's suitable for demanding power‑rectification tasks in electronic circuits.

Why choose the Semtech M20 Single Diode?

The M20 delivers dependable rectification in harsh and high‑voltage environments while maintaining simplicity and affordability. Due to its robust packaging and long lifespan, it’s ideal for applications that require low leakage and consistent performance under stress. Its ease of through‑hole mounting also allows simple integration into power supplies, industrial equipment, and other electronic systems. In short, the M20 combines high-voltage capability, reliability, and cost-effectiveness in one proven package.
