VS-26MB100A

Bridge Rectifier Overview

The Vishay VS-26MB100A is a single-phase bridge rectifier from the VS-26MB series, designed for high-power applications. It features a peak repetitive reverse voltage (Vrrm) of 1000 V and an average forward rectified current (Io) of 25 A. The device supports a peak non-repetitive forward surge current (Ifsm) of 420 A. Electrical characteristics include a maximum peak forward voltage (Vf) of 1.11 V and a maximum peak reverse current (Ir) of 10 µA. It operates within a junction temperature range of -55°C to +150°C and utilizes a D-34 package with screw terminal mounting.

Bridge Rectifier Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type D-34 and terminal configuration match design requirements. Ensure storage conditions comply with moisture sensitivity level standards to prevent internal damage prior to soldering or assembly.

Bridge Rectifier Selection Notes

Select this component when designs demand 1000 V blocking voltage with 25 A continuous current in a compact D-34 form factor. Compare Vf losses against alternative packages if thermal management constraints are critical. Verify that mechanical mounting holes align with PCB or chassis layout specifications before finalizing the bill of materials.

Bridge Rectifier Part Context

The VS-26MB100A belongs to Vishay's VS-26MB series of single-phase bridge rectifiers. This series provides standardized solutions for medium to high-power applications, offering consistent electrical performance across various voltage ratings. The D-34 package ensures compatibility with existing thermal management infrastructure used in industrial electronics manufacturing.

Bridge Rectifier Replacement Considerations

Direct substitutes within the same series include VS-26MB80A (800 V) and VS-26MB120A (1200 V), provided voltage margins allow adjustment. Cross-package replacements like GBPC series require verification of pinout compatibility and thermal resistance differences.
