Overview
The DKR200AB60 is a non-isolated high-speed dual diode module manufactured by SanRex. It features a repetitive peak reverse voltage of 600 V and a DC reverse voltage of 480 V. Each device within the module supports an average forward current of 100 A, with a surge forward current rating of 1700 A at 60 Hz. The maximum forward voltage drop is 1.5 V at 200 A. The unit operates within a junction temperature range of -55°C to +150°C and has a thermal impedance of 0.074 °C/W.
Feature Summary
- High-speed fast recovery design optimized for low loss and high-frequency control applications
- Dual diode configuration providing high surge capability for robust switching performance
- Non-isolated construction suitable for direct mounting in power conversion circuits
Applications
- Switching Power Supplies
- Inverter Welding Power Supplies
- Telecommunication Power Systems
Procurement Notes
Verify component authenticity through authorized SanRex distributors or official channels. Confirm datasheet revision and manufacturing date codes upon receipt. Ensure proper handling procedures are followed due to the screw-mount terminal configuration. Cross-reference part numbers carefully to avoid confusion with isolated variants or different series within the manufacturer's portfolio.
Selection Notes
Select this module for applications requiring fast recovery characteristics and high surge tolerance. Evaluate thermal management requirements based on the specified junction-to-case thermal impedance. Ensure the operating frequency aligns with the soft recovery profile to minimize switching losses. Verify that the system voltage does not exceed the 600 V repetitive peak reverse voltage rating under all transient conditions.
Part Context
This component belongs to the DKR series of high-speed diode modules from SanRex. The series is engineered for high-power switching environments where rapid turn-off speeds are critical. The dual configuration allows for use in bridge rectifier topologies or freewheeling applications within industrial power electronics systems.
Replacement Considerations
Consult official SanRex documentation for verified substitute part numbers. Do not assume compatibility with other manufacturers' dual diode modules without verifying pinout, thermal, and electrical specifications.
