B6M-E3/45 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The B6M-E3/45 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division, rated for 600 V peak reverse voltage and 500 mA average rectified current. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system maintenance, repair, and redesign applications. The through-hole MBM package configuration and standard rectification technology establish the baseline for compatible alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B6M-E3/45 is determined by strict equivalence across the following critical parameters:

• Diode Type: Single Phase
• Technology: Standard
• Voltage - Peak Reverse (Max): 600 V
• Current - Average Rectified (Io): 500 mA
• Mounting Type: Through Hole
• Package / Case: 4-DIP (0.200", 5.08mm)

The MB6M-E3/45 qualifies as a parametric equivalent based on matching all critical electrical and mechanical specifications. Minor variations in forward voltage measurement conditions (1 V @ 400 mA versus 1 V @ 500 mA) remain within acceptable tolerance for single-phase bridge rectifier applications and do not disqualify substitution.
