VS-26MT80

Bridge Rectifier Overview

The VS-26MT80 is a three-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features an average forward current rating of 25 A and a maximum repetitive peak reverse voltage of 800 V. The device utilizes standard technology and is housed in a D-34A package with solder tab terminals for through-hole mounting. Key electrical specifications include a forward voltage of 1.26 V, a non-repetitive peak surge current of 375 A, and a reverse leakage current of 200 µA at the rated voltage. The component operates within a junction temperature range of -55°C to +150°C.

Bridge Rectifier Feature Summary

• Three-phase rectification capability for industrial power conversion
• Robust thermal performance with high junction temperature tolerance
• High surge current handling capacity for transient protection

Bridge Rectifier Applications

• Industrial motor drives and variable frequency drives
• DC power supply input stages
• Battery charging systems

Bridge Rectifier Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the D-34A package dimensions match the target PCB footprint and mounting requirements. Ensure the selected variant meets all environmental operating conditions required for the final application.

Bridge Rectifier Selection Notes

Select this component when a three-phase configuration is required with an 800 V blocking voltage and 25 A continuous current. Compare the 1.26 V forward voltage drop against system efficiency targets. Verify that the 375 A surge rating exceeds the expected inrush currents in the circuit design to ensure reliable operation under fault conditions.

Bridge Rectifier Part Context

This part belongs to the VS-xxMT series of three-phase bridge rectifiers from Vishay. It shares the D-34A package form factor with other variants in the family, such as the VS-26MT60, which offers a lower 600 V rating. The series is designed for general-purpose industrial applications requiring reliable AC-to-DC conversion in compact modules.

Bridge Rectifier Replacement Considerations

The VS-26MT60 is a direct pin-compatible alternative within the same package if the circuit voltage does not exceed 600 V. Other manufacturers may offer equivalent three-phase bridges in the D-34A package, but verification of forward voltage and thermal resistance parameters is necessary.
