GBU4M-7001E3/51

Overview

The GBU4M-E3/51 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes glass passivation for junction protection and is housed in a GBU through-hole package. The device supports a maximum repetitive peak reverse voltage of 1000 V and an average forward rectified current of 4 A at 25 °C. It features a non-repetitive peak forward surge current capability of 150 A. The component operates within a junction temperature range of -55 °C to +150 °C and meets RoHS standards.

Feature Summary

• Glass passivation provides stable leakage characteristics and robust mechanical strength for the semiconductor junctions.
• High surge current capability allows the device to withstand transient overloads during power-up or fault conditions.
• Low forward voltage drop contributes to improved efficiency and reduced heat generation in rectification applications.

Applications

• AC-to-DC conversion in general-purpose power supply circuits
• Battery charging systems requiring high reverse voltage blocking
• Industrial control equipment power stages

Procurement Notes

Verify the exact part number suffix against official Vishay documentation, as variations such as /45 or /73 may indicate different packaging formats while maintaining identical electrical specifications. Confirm that the requested revision matches the required lead frame and molding compound composition for your specific manufacturing process requirements.

Selection Notes

Select this component when a 1000 V rating is necessary for mains-connected or high-voltage DC link applications. Ensure the thermal management design accommodates the 4 A continuous current rating and the associated forward voltage losses. Verify that the GBU footprint aligns with the PCB layout constraints and that the through-hole mounting method suits the assembly line capabilities.

Part Context

This device belongs to the GBU4 series of glass-passivated bridge rectifiers from Vishay. The series offers various voltage ratings ranging from 50 V to 1000 V, sharing the same GBU case style and pinout configuration. The 'M' designation specifically indicates the 1000 V blocking voltage variant within this standardized family of components.

Replacement Considerations

Cross-reference with other manufacturers offering GBU-style 1000 V, 4 A bridge rectifiers. Ensure equivalent peak reverse voltage, forward current, and package dimensions are matched. Verify that any substitute also utilizes glass passivation if environmental stability is a critical design parameter.
