GBU4A-1M3/51

Overview

The GBU4A-1M3/51 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 supports a peak non-repetitive surge current (Ifsm) of 150 A. It utilizes a standard recovery technology with a maximum forward voltage drop of 1 V at the rated current. The component operates within a junction temperature range of -55°C to +150°C and is housed in a GBU through-hole package.

Feature Summary

• Single-phase rectification configuration for AC-to-DC conversion
• Through-hole mounting capability via GBU package
• High surge current handling capacity for transient protection

Applications

• General-purpose power supply circuits
• AC-to-DC rectification in low-voltage applications
• Industrial control systems requiring robust rectification

Procurement Notes

Verify the specific suffix /51 against official Vishay documentation to confirm packaging details and compliance status. Ensure the part number matches the exact electrical specifications required for the design, particularly the 50 V rating and 4 A current limit. Cross-reference with authorized distributors to confirm availability and authenticity.

Selection Notes

Select this component for applications requiring a 50 V reverse voltage rating and 4 A continuous current. The GBU package is suitable for through-hole assembly processes. Consider thermal management requirements given the 150 A surge capability and operating temperature range up to 150°C. Verify that the standard recovery speed meets the circuit's frequency requirements.

Part Context

This part belongs to Vishay's GBU4A series of single-phase rectifier bridges. The series offers various voltage ratings from 50 V to 1000 V while maintaining a consistent 4 A average forward current capability. The GBU4A-1M3/51 specifically denotes the 50 V variant within this standardized product line designed for general-purpose rectification tasks.

Replacement Considerations

Direct replacements must match the 50 V Vrrm, 4 A Io, and GBU package dimensions. Check datasheets for equivalent parts from other manufacturers ensuring identical pinout and thermal characteristics. Verify that any substitute maintains the same surge current rating and recovery time specifications.
