MCR22-6RLRA

Scrs Overview

The MCR22-6RLRA is a Silicon Controlled Rectifier (SCR) manufactured by onsemi, belonging to the MCR22-6 series. It features a rated repetitive off-state voltage of 400 V and an RMS on-state current of 1.5 A. The device supports non-repetitive peak on-state currents up to 15 A with a maximum holding current of 5 mA. Gate triggering requirements include a maximum DC gate trigger current of 0.2 mA and a maximum DC gate trigger voltage of 0.8 V. It operates within a temperature range of -40°C to +125°C and is housed in a TO-92-3 package.

Scrs Feature Summary

• Provides reliable switching capability for AC power control applications through a standard three-terminal SCR structure.
• Designed for robust performance in industrial environments with a wide operating temperature range extending to +125°C.
• Features low gate trigger current requirements to facilitate efficient drive circuit design.

Scrs Applications

• AC power control circuits
• Lighting dimmer applications
• Motor speed control systems

Scrs Procurement Notes

Verify the specific suffix RLRA against official onsemi documentation to confirm exact packaging and tape-and-reel specifications. Confirm availability status as distribution channels may vary. Ensure compliance with RoHS directives if required by the target application. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Scrs Selection Notes

Select this component when a 400 V blocking voltage and 1.5 A continuous current rating are required in a compact TO-92 package. Consider the thermal management capabilities given the +125°C junction temperature limit. Evaluate gate drive compatibility with the specified 0.2 mA trigger current. Compare against alternative thyristors if higher current or voltage ratings are needed for the specific system design.

Scrs Part Context

This device is part of the MCR22-6 family of SCRs from onsemi, designed for general-purpose power switching. The family typically includes variants with different voltage ratings and packaging options. These components are widely used in consumer electronics and industrial equipment requiring simple, cost-effective AC phase control solutions.

Scrs Replacement Considerations

Direct replacements must match the 400 V rating, 1.5 A current capacity, and TO-92-3 footprint. Verify pinout compatibility and electrical characteristics such as gate trigger voltage and holding current. Consult onsemi's official substitution guides for qualified alternatives.
