Overview
The BKR400AB10 is a non-isolated dual-common cathode Schottky diode module manufactured by SanRex. It features a maximum repetitive peak reverse voltage of 100 V and supports a maximum average forward current of 400 A at a case temperature of 112°C with a 50% duty cycle. The typical forward voltage drop is 0.93 V at 400 A. The device operates within a junction temperature range of -40°C to +150°C and has a thermal resistance from junction to case of 0.2°C/W. It utilizes screw mounting for secure installation.
Feature Summary
- Dual-common cathode configuration designed for high-power rectifier circuits
- Low forward voltage drop characteristics to minimize power loss
- High surge on-state current capability for robust performance
- Screw mount construction suitable for industrial applications
Applications
- Switching power supplies
- Power supplies for metal surface treatment
- Telecommunication power supplies
Procurement Notes
Verify the specific datasheet revision and RoHS compliance status directly with the manufacturer or authorized distributor before finalizing procurement decisions. Confirm that the mounting torque specifications align with your assembly equipment capabilities to ensure reliable mechanical connections and optimal thermal performance during operation.
Selection Notes
Select this component for applications requiring high current handling with low conduction losses. Ensure the cooling system maintains the case temperature below 112°C to sustain the rated 400 A average forward current. Verify that the circuit voltage does not exceed the 100 V repetitive peak reverse voltage rating under all operating conditions.
Part Context
This module belongs to the BKR series of discrete semiconductor modules produced by SanRex. The series focuses on silicon-based Schottky barrier diodes intended for high-efficiency power conversion. The BKR400AB10 represents a specific variant optimized for high-current, low-voltage rectification tasks in demanding industrial environments.
Replacement Considerations
Consult official SanRex documentation for confirmed substitute part numbers. Do not assume cross-compatibility with other manufacturers' modules without verifying electrical parameters, pin configurations, and thermal characteristics against the original specifications.
