GBU4A-M3/51

Overview

The GBU4A-M3/51 is a single-phase rectifier bridge manufactured by Vishay General Semiconductor - Diodes Division. It features a peak repetitive reverse voltage (Vrrm) of 50 V and an average forward rectified current (Io) of 4 A. The device has a maximum non-repetitive peak forward surge current (Ifsm) of 150 A and a typical peak forward voltage (Vf) of 1 V. It utilizes a GBU surface-mount package with four pins and operates within a junction temperature range of -55°C to 150°C.

Feature Summary

• Single-phase rectification configuration
• Surface-mount GBU package design
• High thermal stability up to 150°C

Applications

• General-purpose AC-to-DC power conversion
• Low-voltage DC power supply circuits
• Battery charging systems

Procurement Notes

Verify the specific suffix against official Vishay documentation, as standard listings often reference the GBU4A-E3/51 variant. Confirm RoHS compliance status and ensure the ordering code matches the exact pinout and packaging requirements for your assembly process before finalizing procurement.

Selection Notes

Select this component for applications requiring low-voltage rectification in compact surface-mount designs. Ensure the circuit's peak inverse voltage does not exceed 50 V and that the average load current remains below 4 A. Verify thermal management capabilities are sufficient for the expected operating environment.

Part Context

This part belongs to the GBU4A series of single-phase rectifier bridges from Vishay. It is designed for general-purpose rectification tasks where space constraints favor surface-mount technology over through-hole alternatives. The series offers standardized performance for common low-voltage power applications.
