VJ248M

Bridge Rectifier Overview

The VJ248M is a single-phase bridge rectifier manufactured by Microsemi Corporation. It features a 200V maximum repetitive peak reverse voltage (VRRM) and supports a DC output current of 10 Amps with a 100 Amp surge current capability. The device utilizes glass passivated die construction for reliability. Electrical characteristics include a maximum instantaneous forward voltage of 1.3 Volts per leg at 25°C and a maximum peak reverse current of 5µA per leg. Thermal resistance from junction to case is rated at 3°C/W, allowing operation within a junction temperature range of -55°C to 175°C.

Bridge Rectifier Feature Summary

• Glass passivated die construction ensures stable electrical performance and long-term reliability under varying thermal conditions.
• High surge current capability allows the component to withstand transient load spikes without failure.
• Low thermal resistance design facilitates efficient heat dissipation from the junction to the mounting case.

Bridge Rectifier Applications

• General-purpose AC to DC power conversion circuits
• Industrial power supply modules requiring robust rectification
• Automotive electronics systems operating in high-temperature environments

Bridge Rectifier Procurement Notes

Verify the specific voltage rating suffix when ordering, as the VJ series includes variants up to 2000V. Confirm that the procurement channel provides original manufacturer documentation. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure storage conditions remain within the specified temperature range to maintain component integrity prior to installation.

Bridge Rectifier Selection Notes

Select this component based on the required 200V blocking voltage and 10A continuous current capacity. Evaluate the thermal management solution to ensure the case temperature remains within limits given the 3°C/W thermal resistance. Consider the mechanical mounting requirements, specifically the torque specifications for the #6 screw terminals. Compare against other VJ series parts if higher voltage ratings are needed for the application.

Bridge Rectifier Part Context

The VJ248M belongs to the VJ248M through VJ1048M family of bridge rectifiers produced by Microsemi. This series covers voltage ratings from 200V to 2000V while maintaining consistent current and physical characteristics. The family shares similar packaging and thermal profiles, differing primarily in their peak reverse voltage capabilities. This part serves as the lowest voltage option in the standard lineup.

Bridge Rectifier Replacement Considerations

Direct replacements must match the 10A current rating and 200V minimum reverse voltage. Verify that alternative components offer comparable thermal resistance and surge current handling. Ensure the replacement package matches the mounting hole dimensions and terminal configuration to fit existing PCB layouts or chassis mounts.
