Single Diodes datasheet and documents for HER205G
Single Diodes Overview
The HER205G is a glass-passivated high-efficiency rectifier diode manufactured by Taiwan Semiconductor Corporation. It features a single-phase, one-element silicon junction configuration housed in a DO-15 through-hole package with two pins. The device supports a maximum average forward rectified current of 2A and a peak repetitive reverse voltage of 400V. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 60A, a low forward voltage drop of 1.3V, and a peak reverse recovery time of 50ns. It operates within a temperature range of -55°C to +150°C.
Single Diodes Feature Summary
