Overview
The BKR400ABZ50 is a non-isolated Schottky diode module manufactured by SanRex. It features a dual-common cathode configuration with two independent legs. The repetitive peak reverse voltage (VRRM) is rated at 50 V. The average forward current (IF(AV)) is specified as 200 A per leg, totaling 400 A for the module at a case temperature of 121°C. The forward voltage drop (VFM) is 0.57 V at an IF of 400 A. The operating junction temperature range extends from -40°C to +150°C.
Feature Summary
- Low forward voltage drop characteristic designed for high-efficiency power applications
- High surge current capability supporting demanding transient loads
- Dual-common cathode configuration suitable for bridge rectifier circuits
Applications
- Switching power supplies
- Power supplies for metal surface treatment
- Telecommunication power systems
Procurement Notes
Verify the specific ordering suffix Z50 against official documentation to confirm package and terminal specifications. Ensure thermal management aligns with the specified junction-to-case thermal impedance values. Confirm mounting torque requirements for M6 terminals to maintain reliable electrical contact and mechanical stability during operation.
Selection Notes
Select this component for applications requiring low conduction losses at high currents. The 50 V rating suits low-voltage output stages. Verify that the required surge current capacity meets the circuit's fault conditions. Ensure the cooling system can maintain the case temperature within limits to support the 400 A total current rating.
Part Context
This module belongs to the BKR series of Schottky diode modules from SanRex. These components are silicon-based discrete semiconductor devices intended for power conversion. The series is characterized by fast switching speeds and low forward voltage drops, making them suitable for modern high-frequency power electronics designs.
Replacement Considerations
Consult official substitution lists for verified equivalents. Generic replacements must match the 50 V reverse voltage, 400 A current rating, and dual-common cathode configuration. Verify thermal resistance and physical dimensions before integration.
