Overview
The IXYS MDK950-20N1W is a high-power diode module rated for 2000V reverse voltage and 950A average forward current. It features a dual common cathode configuration, providing two independent rectifying paths within a single package. Designed for industrial applications requiring robust power handling, the module utilizes standard rectifier technology to ensure reliable operation under high thermal and electrical stress conditions.
Feature Summary
- High voltage blocking capability of 2000V
- High current capacity of 950A per element
- Dual common cathode topology for flexible circuit design
Applications
- Industrial motor drives
- DC power supply systems
- Welding equipment rectifiers
Procurement Notes
Verify the specific suffix N1W against the manufacturer's latest datasheet to confirm pinout and mounting specifications. Ensure thermal interface materials are compatible with the module's base plate requirements. Cross-reference part numbers with Littelfuse documentation as IXYS has been acquired, confirming that the MDK950-20N1W designation remains valid for procurement and replacement purposes in existing designs.
Selection Notes
Select this module when system requirements demand high current density combined with high voltage isolation in a compact footprint. The dual common cathode arrangement allows for bridge or push-pull configurations without additional discrete components. Evaluate thermal management capabilities to ensure the junction temperature remains within safe operating limits during peak load conditions.
Part Context
This component belongs to the MDK series of high-power diode modules from IXYS, now part of Littelfuse. The series is engineered for heavy-duty industrial power conversion tasks. The MDK950-20N1W represents a specific variant optimized for 2kV applications, distinguishing it from lower voltage counterparts like the MDK950-12N1W which is rated for 1200V.
Replacement Considerations
The ASMDK950-20-N1W is listed as a replacement or equivalent part number for the MDK950-20N1W. Verify mechanical dimensions and terminal compatibility before substitution.
