BR2501

Bridge Rectifier Overview

The BR2501 is a single-phase silicon bridge rectifier from the BR2500 series, rated for a maximum average forward current of 25 A at a case temperature of 55°C. It features a peak repetitive reverse voltage (VRRM) of 100 V and a maximum RMS voltage of 70 V. The device exhibits a maximum forward voltage drop of 1.1 V at 12.5 A and supports a peak forward surge current of 300 A under JEDEC conditions. Electrical characteristics include a maximum DC reverse current of 10 μA at 25°C and 200 μA at 100°C. Thermal resistance from junction to case is typically 1.45 °C/W, with an operating junction temperature range spanning -40°C to +150°C.

Bridge Rectifier Feature Summary

• Integrates a metal heatsink within the molded plastic encapsulation for efficient thermal dissipation.
• Rated isolation voltage of 2000 V ensures high dielectric strength between terminals.
• Terminals are plated .25" Faston lugs designed for bolt-down mounting on heat sinks using silicone thermal compound.

Bridge Rectifier Applications

• Power supply units requiring single-phase AC to DC conversion.
• Industrial equipment utilizing resistive or inductive loads.
• Applications necessitating high reliability and low reverse leakage currents.

Bridge Rectifier Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm terminal plating integrity and heatsink attachment quality during incoming inspection. Ensure storage conditions remain within specified temperature ranges to maintain epoxy performance. Validate that ordering suffixes match the exact electrical ratings required for the target circuit design.

Bridge Rectifier Selection Notes

Select this component when a 100 V blocking voltage is required alongside a continuous 25 A current capacity. Consider the 1.45 °C/W thermal resistance for heat sink sizing calculations. Derate the forward current by 20% if the application involves capacitive loads to prevent overstress. Ensure the mounting surface allows for effective thermal transfer using appropriate silicone compounds.

Bridge Rectifier Part Context

This part belongs to the BR2500 through BR2510 series, which share identical current and thermal ratings but vary in reverse voltage capabilities ranging from 50 V to 1000 V. The BR2501 specifically addresses circuits requiring 100 V blocking capability. All variants utilize the same mechanical package and terminal configuration for interchangeability in physical layout.

Bridge Rectifier Replacement Considerations

Cross-reference with other manufacturers offering 25 A, 100 V bridge rectifiers in similar metal-heatsink packages. Verify that substitute components meet the 300 A surge current requirement and 1.1 V forward voltage drop limits. Ensure terminal dimensions and mounting hole spacing match the existing PCB or chassis design constraints.
