D25SB60 25A 600V Single-Phase Bridge Rectifier

The D25SB60 is a high-current, glass-passivated single-phase bridge rectifier designed to convert AC voltage into pulsating DC voltage, commonly used in power supply and rectification circuits. Rated for a maximum average forward current of 25A and a maximum repetitive reverse voltage of 600V, this device is well-suited for moderate-to-high power AC-to-DC conversion applications where reliability and surge tolerance are important.

The rectifier integrates four diode junctions into a single compact molded package, eliminating the need for four separate discrete diodes in a full-wave bridge configuration. It features glass-passivated chip junctions for excellent reverse leakage performance and long-term reliability, along with a high peak forward surge current rating of 350A, allowing it to safely absorb sudden inrush current spikes without damage - an important characteristic when powering capacitive input filters or large loads at startup.

Housed in the compact SIP-4P (Single In-line Package, 4-Pin) case with a metal mounting hole for heatsink attachment, the device features clearly marked polarity terminals (+, ~, ~, −) for straightforward wiring - the two "~" terminals accept the AC input, while the DC output is taken across the + and − pins. Its plastic molding compound carries a UL 94V-0 flammability rating, and the design offers superior thermal conductivity along with high dielectric isolation strength between the terminals and the mounting case.
