CMA50E1600TZ-TRL

Scrs Overview

The CMA50E1600TZ-TRL is a single Silicon Controlled Rectifier (SCR) manufactured by IXYS, designed for surface-mount applications in the D3PAK-3 (TO-268-3) package. It features a rated repetitive off-state voltage (VDRM) of 1.6 kV and an on-state RMS current (It RMS) of 79 A. The device exhibits a forward voltage drop (Vf) of 1.66 V, with a gate trigger voltage (Vgt) of 1.5 V and a gate trigger current (Igt) of 50 mA. It operates within a temperature range of -40°C to +125°C, supports a non-repetitive on-state current of 550 A, and has a maximum holding current (Ih) of 100 mA.

Scrs Feature Summary

• Surface-mount construction in a TO-268-3 package for automated PCB assembly
• High voltage blocking capability at 1.6 kV for robust power control
• Low gate trigger current requirement for efficient driver interface

Scrs Applications

• Phase control circuits for AC power regulation
• Industrial motor drive systems
• Solid-state relay implementations

Scrs Procurement Notes

Verify component authenticity through manufacturer channels or authorized distributors. Confirm RoHS compliance status via official documentation. Ensure storage conditions maintain integrity prior to soldering. Validate package marking against datasheet specifications to prevent counterfeit substitution during receipt inspection.

Scrs Selection Notes

Select this SCR when high-voltage isolation and surface-mount convenience are required. Compare Vf and Igt requirements against available gate drivers. Assess thermal management needs based on the 79 A RMS rating and operating environment. Verify that the TO-268-3 footprint matches the target PCB layout constraints.

Scrs Part Context

This component belongs to the IXYS CMA series of power thyristors, which are engineered for high-efficiency energy conversion. The series typically includes variants with different current ratings and packaging options, such as through-hole TO-247 or tube-packaged versions, allowing designers to scale power handling while maintaining consistent electrical characteristics across the product line.

Scrs Replacement Considerations

Cross-reference with other IXYS CMA series SCRs sharing the 1.6 kV rating and TO-268-3 package. Verify pinout compatibility and thermal resistance values before substituting. Ensure alternative parts meet the same 79 A RMS and 1.66 V Vf specifications for direct interchangeability.
