MCMA35PD1200TB

Overview

The MCMA35PD1200TB is a dual thyristor module manufactured by IXYS, designed for high-power industrial applications. It features a series configuration of one SCR and one diode within a TO-240AA package. The device supports a maximum repetitive off-state voltage of 1.2 kV and an average on-state current of 35 A. Root mean square on-state current reaches 55 A, with non-repetitive surge currents of 520 A at 50 Hz and 560 A at 60 Hz. Gate trigger parameters include a maximum voltage of 1.5 V and current of 78 mA. The holding current is 200 mA, and the junction temperature range spans from -40°C to 140°C.

Feature Summary

• Dual structure integrating one SCR and one diode in a single series configuration
• High-voltage capability rated at 1.2 kV for robust power control
• Base-mount installation design suitable for thermal management in heavy-duty systems

Applications

• Wind turbine pitch drive systems
• Heavy-duty frequency converters
• Industrial motor drives operating at variable frequencies

Procurement Notes

Verify the specific suffix 'TB' against official Littelfuse/IXYS documentation to confirm pinout and thermal interface specifications. Ensure the component matches the TO-240AA footprint requirements. Cross-reference datasheet electrical limits with system load profiles to prevent gate trigger failures or thermal overstress during operation.

Selection Notes

Select this module when a combined SCR and diode solution is required in a compact form factor. The 1.2 kV rating suits medium-voltage AC control circuits. Consider the 35 A continuous current limit and 55 A RMS capacity against peak load demands. The TO-240AA package dictates specific heatsinking and mounting hardware requirements for reliable thermal dissipation.

Part Context

This component belongs to the IXYS Dual Thyristor Modules portfolio, which offers various packages and breakdown voltages up to 2200V. The MCMA series provides integrated solutions for applications requiring both phase control and freewheeling functions. The manufacturer, now part of Littelfuse, maintains this product line for industrial power electronics markets.
