Overview
The SanRex DCA150BA65 is a single-channel soft recovery diode module with a repetitive peak reverse voltage of 650 V and an average forward current rating of 150 A. It features a maximum forward voltage drop of 1.70 V at 150 A and a reverse recovery time of 200 ns. The junction-to-case thermal resistance is 0.34 °C/W, supporting operation within a temperature range of -40 °C to +150 °C. The component utilizes silicon technology and includes an isolated package design for simplified heatsink construction.
Feature Summary
- Soft recovery characteristics with low reverse recovery time
- Electrically isolated package structure
- High surge forward current capability
Applications
- Switching power supplies
- Welding power supplies
- Cutting machines
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm electrical ratings. Confirm mounting torque specifications for M6 terminals during installation. Ensure compliance with RoHS directives as indicated in manufacturer records. Validate thermal management requirements based on the specified junction-to-case resistance values.
Selection Notes
Select this component for applications requiring high-speed switching with controlled reverse recovery behavior. The isolated package facilitates direct mounting to grounded heatsinks without additional insulation components. Verify that the operating junction temperature remains within the specified limits under all expected load conditions.
Part Context
This device belongs to the DCA series of discrete semiconductor modules manufactured by SanRex. It is designed for general-purpose power rectification and freewheeling applications where fast switching and low loss are required. The module integrates silicon diode elements into a robust screw-mount housing.
Replacement Considerations
Consult official substitution lists for verified equivalents. Cross-reference parameters such as reverse voltage, forward current, and recovery time when evaluating alternative components.
