CMA20E1600PB

Scrs Overview

The CMA20E1600PB is a single Silicon Controlled Rectifier (SCR) manufactured by IXYS, designed for high-voltage power control applications. It features a rated repetitive off-state voltage (VDRM) of 1.6 kV and an on-state RMS current (IT RMS) of 35 A. The device exhibits a forward voltage drop of 1.46 V, with a gate trigger voltage of 1.3 V and a gate trigger current of 28 mA. It supports a non-repetitive surge current of 180 A and maintains a holding current maximum of 60 mA. Operating within a temperature range of -40°C to +125°C, the component utilizes a TO-220-3 through-hole package.

Scrs Feature Summary

• High voltage blocking capability up to 1.6 kV for robust off-state performance
• Standard recovery characteristics suitable for general power switching tasks
• Through-hole mounting configuration for secure mechanical installation

Scrs Applications

• Industrial motor drive systems requiring high-voltage isolation
• Power supply circuits utilizing thyristor-based regulation
• General purpose AC/DC power control modules

Scrs Procurement Notes

Verify the specific manufacturer part number against official IXYS documentation to ensure authenticity. Confirm that the received components match the specified TO-220-3 package dimensions and pinout configuration. Check for any recent product change notifications regarding material composition or testing standards. Ensure storage conditions comply with semiconductor handling guidelines to prevent moisture sensitivity issues prior to soldering.

Scrs Selection Notes

Select this component when a 1.6 kV blocking voltage and approximately 35 A continuous current capacity are required in a standard through-hole form factor. Consider the 1.46 V forward voltage drop for thermal management calculations. Evaluate the gate trigger requirements against available driver circuit capabilities. Compare alternative packages if surface-mount solutions are preferred for automated assembly processes.

Scrs Part Context

This SCR belongs to the IXYS CMA series of discrete thyristors, which are engineered for reliable operation in demanding power electronics environments. The series offers various current ratings and packaging options to accommodate different thermal and spatial constraints. As a single-phase device, it serves as a fundamental building block for controlling high-power loads in industrial and commercial electrical systems.

Scrs Replacement Considerations

Cross-reference with other IXYS SCRs offering similar 1.6 kV ratings and comparable current capacities. Verify pin compatibility and thermal resistance values before substituting with devices from other manufacturers. Ensure that any alternative component meets the same operating temperature range and regulatory compliance standards.
