GBL04-M3/51

Overview

The GBL04-M3/51 is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a single diode configuration in the GBL package, designed for surface-mount applications. The device supports a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current of 2 A per lead. Forward voltage is specified at 1.1 V when conducting 2 A. The component utilizes standard recovery technology with a maximum reverse recovery time of 500 ns under conditions where forward current exceeds 200 mA. Reverse leakage current is limited to 5 µA at the rated reverse voltage of 400 V. Junction capacitance is 15 pF measured at 4 V and 1 MHz. The unit operates within a junction temperature range of -55°C to 150°C.

Feature Summary

• Surface-mount construction in the GBL package for automated assembly
• Standard recovery characteristics suitable for general-purpose rectification
• High thermal stability with extended operating temperature range

Applications

• AC-DC converter circuits
• Power supply rectification stages
• General-purpose freewheeling applications

Procurement Notes

Verify the specific ordering suffix against official Vishay documentation to confirm package type and tape-and-reel specifications. Ensure the selected variant matches the required packaging format for the intended manufacturing process. Cross-reference the full part number with the manufacturer's current product status to confirm availability and compliance with relevant standards before finalizing procurement plans.

Selection Notes

Select this component for designs requiring a 400 V blocking capability and 2 A continuous current handling in a compact surface-mount footprint. Evaluate the 1.1 V forward voltage drop for efficiency requirements in low-voltage output stages. Confirm that the standard recovery speed meets the switching frequency constraints of the target application without generating excessive electromagnetic interference.

Part Context

This part belongs to Vishay's GBL series of bridge rectifiers and discrete diodes in surface-mount packages. The M3 suffix indicates halogen-free and RoHS-compliant construction. The /51 suffix typically denotes a specific tape-and-reel quantity or packaging variation defined by the manufacturer. This series provides a transition from traditional through-hole GBL configurations to modern SMD assembly methods while maintaining similar electrical performance profiles.

Replacement Considerations

Direct replacements must match the 400 V rating, 2 A current capacity, and GBL package dimensions. Verify pinout compatibility and thermal resistance characteristics. Alternative manufacturers offering equivalent standard recovery diodes in the GBL form factor should be evaluated for electrical parameter parity and mechanical fit.
