Overview
The MDA950-20N1W is a high-voltage standard rectifier module manufactured by IXYS. It features a current capacity of 950 A and a maximum reverse voltage (Vr) of 2000 V. The forward voltage drop (Vf) is specified at 880 mV when operating at 500 A. This component utilizes a standard recovery technology with a reverse recovery time (trr) of 18 µs. Designed for robust power electronics applications, it is housed in a module package configuration suitable for high-load scenarios requiring efficient rectification.
Feature Summary
- High current handling capability up to 950 A
- High voltage blocking rating of 2000 V
- Standard recovery characteristics for reliable switching
Applications
- High-load industrial power conversion systems
- Medium frequency rectification circuits
- Power electronics filtering and smoothing applications
Procurement Notes
Verify the specific datasheet version and electrical parameters against official IXYS documentation before integration. Confirm that the module package type matches your thermal management and mechanical design requirements. Ensure that the 18 µs reverse recovery time aligns with your circuit's switching frequency constraints to prevent excessive losses or failure.
Selection Notes
Select this module when applications demand high current capacity combined with high voltage isolation. Consider the 880 mV forward voltage drop at 500 A for thermal calculations. Evaluate the 18 µs reverse recovery time against system switching speeds. Compare against other IXYS modules like the MDA600 series if lower current ratings suffice for the specific load profile.
Part Context
This part belongs to the IXYS MDA950 series of high-power rectifier modules. It shares design principles with other MDA series components but offers distinct current and voltage ratings tailored for heavy-duty power electronics. The module format integrates multiple diode elements into a single compact unit for efficient heat dissipation and space-saving installation in industrial inverters and converters.
Replacement Considerations
Potential substitutes include the MDA950-14N1W and MDA950-16N1W from the same manufacturer. Verify compatibility regarding pin arrangement, thermal resistance, and exact electrical limits before substitution.
