W04 Bridge Rectifier

The W04 Bridge Rectifier is a compact 4-pin single-phase full-wave bridge rectifier designed to convert alternating current (AC) into smooth direct current (DC). Rated for a maximum repetitive peak reverse voltage of 400V and a continuous forward current of up to 1.5 Amperes, it is ideal for small to medium power supply applications.

Housed in a durable round WOB glass-passivated molded plastic package, it provides low forward voltage drop, high surge current capability, and reliable heat dissipation. Its lead pins are clearly labeled (+, -, AC, AC) for straightforward circuit integration.

It is compatible with step-down transformer power supplies, AC-DC adapters, battery chargers, LED drivers, motor control power units, and general embedded DIY electronic systems.
