MCMA85PD1600TB

Overview

The IXYS MCMA85PD1600TB is a silicon SCR module rated for an average on-state current of 85A and a repetitive peak reverse voltage of 1600V. It features a surge current rating of 1.27kA and a maximum gate trigger current of 200mA. The device utilizes a TO-240 package with panel mounting, supporting an operating temperature range from -40°C to +140°C.

Feature Summary

• High-power thyristor capability within a compact TO-240 form factor
• Robust thermal management for high-temperature industrial environments
• Standardized pin configuration for straightforward integration

Applications

• Industrial motor drives
• Power supply systems
• Welding equipment

Procurement Notes

Verify the specific suffix against official datasheets to confirm exact electrical tolerances and pinout configurations. Ensure compatibility with existing heatsinking infrastructure due to the TO-240 package dimensions. Confirm that the 85A continuous current rating aligns with the thermal design of the target application circuit.

Selection Notes

Select this component when a single-phase SCR solution is required with moderate current handling capabilities. The 1600V blocking voltage suits medium-voltage AC applications. Consider the 140°C junction temperature limit for high-reliability designs requiring extended operational margins under heavy load conditions.

Part Context

This part belongs to the IXYS MCMA series of discrete semiconductor modules. These components are designed for general-purpose power control applications. The series offers various current ratings while maintaining consistent mechanical footprints to simplify board layout and assembly processes across different product generations.

Replacement Considerations

Consult manufacturer cross-reference guides for verified equivalents. Ensure substitute parts match the 1600V rating and TO-240 mechanical constraints.
