Overview
The MCR22-006 is a silicon-controlled rectifier (SCR) manufactured by onsemi, designed for general-purpose triggering applications. It features a single-phase configuration housed in a TO-92 package. Key electrical specifications include a maximum repetitive peak off-state voltage of 400V and a maximum RMS on-state current of 1.5A. The device has a maximum DC gate trigger current of 0.2mA and a maximum DC gate trigger voltage of 0.8V. It exhibits a holding current of 5mA and a non-repetitive peak on-state current of 15A. The typical circuit commutation turn-off time is 40µs, with a critical rate of rise of off-state voltage of 25V/µs.

Procurement Notes
Verify the specific suffix code to ensure correct voltage and current ratings, as variations exist within the MCR22 series. Confirm RoHS compliance status if required for your assembly process. Check the datasheet for precise thermal resistance values and derating curves to ensure safe operation under your specific load conditions. Ensure the TO-92 package dimensions match your PCB footprint requirements.
Selection Notes
Select this component when a low-cost, general-purpose SCR is needed for moderate current switching. Compare the 400V rating against your peak inverse voltage requirements. Consider the 1.5A continuous current limit for your load. Evaluate the gate trigger characteristics against your driving circuit's output capabilities. Verify that the TO-92 package meets your mechanical and thermal constraints.
Part Context
The MCR22 series comprises silicon-controlled rectifiers from onsemi, widely used in consumer electronics and industrial controls. These devices are known for their reliability and ease of use in phase-control applications. The series offers various voltage ratings to suit different AC line voltages. They are commonly found in household appliances and power supplies where simple, robust switching is required.
Replacement Considerations
Check for direct pin-compatible replacements such as the MCR100 series or equivalent SCRs from other manufacturers like Littelfuse or Vishay. Ensure the replacement part matches the 400V voltage rating and 1.5A current handling capacity. Verify that the gate trigger parameters are compatible with your existing circuit design.
