MDMA50P1600TG

Overview

The MDMA50P1600TG is a silicon SCR module manufactured by IXYS, rated for a repetitive peak off-state voltage of 1600 V and an RMS on-state current of 50 A. It utilizes the TO-240AA package with seven pins for panel mounting. The device operates within a junction temperature range of -40°C to +125°C and features a non-repetitive peak surge current capability of 780 A.

Feature Summary

• Engineered for phase control applications in line-frequency circuits
• Utilizes planar passivated chip technology for enhanced reliability
• Designed for robust performance in industrial power conversion systems

Applications

• Industrial motor drives
• AC power controllers
• Welding equipment

Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and thermal characteristics. Ensure compatibility with existing heatsinking solutions due to the TO-240AA form factor. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when a 1600 V blocking voltage and 50 A continuous current rating are required in a standard TO-240AA footprint. Consider the 7-pin configuration for simplified gate and main terminal connections compared to alternative packages. Evaluate thermal resistance requirements against the specified maximum operating temperature limits.

Part Context

This part belongs to the MDMA series of thyristor modules from IXYS, designed for high-power industrial applications. The series typically employs direct copper bonding to aluminum oxide substrates for efficient heat dissipation. These modules are intended for use in environments requiring reliable phase control at line frequencies.

Replacement Considerations

Cross-reference with MCMA50P1600TA or similar IXYS TO-240AA SCR modules for mechanical fit. Verify electrical parameters such as gate trigger current and holding current before substitution.
