FRS400BA60

Overview

The SanRex FRS400BA60 is a high-speed isolated diode module designed for high-power switching applications. It features a repetitive peak reverse voltage of 600 V and a DC reverse voltage of 480 V. The module supports a forward current of 400 A at a case temperature of 94°C, with a surge forward current capability of 4000 A. Key electrical characteristics include a maximum forward voltage drop of 1.4 V and a typical reverse recovery time of 130 ns. The operating junction temperature range spans from -40°C to +150°C.

Feature Summary

• High-speed fast recovery design optimized for low loss and high-frequency control
• Isolated mounting base providing 2500 V RMS isolation breakdown voltage
• High surge current capability supporting demanding transient loads

Applications

• Inverter welding power supplies
• Telecommunication power supplies
• Various switching power supply systems

Procurement Notes

Verify the specific suffix (50 or 60) to confirm the required voltage rating before procurement. Confirm that the thermal management system can maintain the case temperature within specified limits to ensure the rated 400 A forward current is sustained. Ensure mounting torque adheres to the recommended M6 terminal specifications to prevent mechanical failure.

Selection Notes

Select this component when high-speed switching and low reverse recovery charge are critical for efficiency. The isolated base simplifies heatsinking requirements compared to non-isolated modules. Verify that the application's peak reverse voltage does not exceed the 600 V rating under all operating conditions and transients.

Part Context

This part belongs to the FRS400BA series of fast recovery diode modules manufactured by SanRex. The series is engineered for industrial power conversion where speed and isolation are paramount. The FRS400BA60 variant specifically addresses applications requiring higher voltage blocking capabilities than the 500 V rated counterpart.
