483-02

Bridge Rectifier Overview

The Microchip Technology 483-02 is a three-phase bridge rectifier designed for chassis mount applications. It features a standard recovery type configuration with a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current rating of 15 A per leg. The device operates within a junction temperature range of -65°C to +175°C and utilizes a metal envelope (ME) package style.

Bridge Rectifier Feature Summary

• Three-phase bridge rectification capability
• Chassis mount construction for robust thermal management
• High junction temperature tolerance

Bridge Rectifier Applications

• Industrial power conversion systems
• Motor drive rectification circuits
• DC power supply input stages

Bridge Rectifier Procurement Notes

Verify the specific datasheet revision and mechanical drawing dimensions before integration, as chassis mount components require precise mounting hole alignment. Confirm that the thermal interface material and torque specifications meet the manufacturer's requirements for reliable operation at high currents. Ensure the 400 V rating aligns with the system's peak inverse voltage demands.

Bridge Rectifier Selection Notes

Select this component when a rugged, high-current three-phase rectification solution is required in industrial environments. The ME package offers superior heat dissipation compared to plastic packages. Consider the 15 A current rating and 400 V blocking voltage to ensure adequate margin for the specific application load and line conditions.

Bridge Rectifier Part Context

This part belongs to Microchip Technology's legacy rectifier portfolio, often associated with former Micrel products. It serves as a discrete solution for converting three-phase AC to DC in heavy-duty applications where reliability and thermal performance are critical priorities over miniaturization.

Bridge Rectifier Replacement Considerations

Cross-reference with other Microchip or Micrel three-phase bridge rectifiers in the ME package family. Verify pinout compatibility and mechanical footprint dimensions before substituting with equivalent parts from other manufacturers.
