VS-93MT120KPBF

Bridge Rectifier Overview

The VS-93MT120KPBF is a three-phase standard bridge rectifier manufactured by Vishay General Semiconductor. It features a peak reverse voltage of 1.2 kV and an average rectified current rating of 90 A. The device utilizes the MT-K chassis mount package, designed for robust thermal management in high-power applications. Operating within a junction temperature range of -65°C to +175°C, this component ensures reliable performance under demanding electrical conditions.

Bridge Rectifier Feature Summary

• Three-phase rectification architecture for industrial power conversion
• Chassis mount design facilitating direct heatsink integration
• High thermal stability supporting extended operating temperatures

Bridge Rectifier Applications

• Industrial motor drives and variable frequency drives
• High-power DC power supply systems
• Welding equipment power stages
• Uninterruptible power supply (UPS) input stages

Bridge Rectifier Procurement Notes

Verify the specific suffix KPBF confirms lead-free and RoHS compliance status prior to ordering. Confirm that the MT-K package dimensions match the mechanical constraints of the intended chassis mounting solution. Ensure thermal interface materials are compatible with the specified operating temperature range to maintain junction temperature limits during continuous operation.

Bridge Rectifier Selection Notes

Select this component when three-phase AC-to-DC conversion is required at voltages up to 1.2 kV and currents near 90 A. The chassis mount form factor is essential where board space is limited but significant heat dissipation is necessary. Evaluate thermal resistance requirements against the system's cooling capabilities to ensure the junction temperature remains within safe operational limits under full load conditions.

Bridge Rectifier Part Context

This part belongs to Vishay's VS-90 series of three-phase bridge rectifiers. The series offers various voltage ratings and current capacities tailored for different power levels. The MT-K designation indicates a specific metal tab package style optimized for screw-down mounting onto cold plates or chassis structures, distinguishing it from through-hole or surface-mount alternatives.

Bridge Rectifier Replacement Considerations

Cross-reference with other Vishay parts in the VS-90 series for alternative voltage ratings such as VS-93MT160KPBF. Verify pinout compatibility and mechanical footprint equivalence before substituting with components from other manufacturers. Ensure replacement devices meet or exceed the original 1.2 kV reverse voltage and 90 A current specifications.
