MCR218-2G

Overview

The MCR218-2G is a silicon controlled rectifier (SCR) from Littelfuse, rated for 50 V repetitive off-state voltage and 8 A RMS on-state current. It features a maximum gate trigger current of 25 mA and a forward voltage of 1.8 V. The device operates within a temperature range of -40°C to +125°C and utilizes a TO-220AB through-hole package.

Feature Summary

Designed primarily for half-wave AC control applications
Suitable for motor controls, heating controls, and power supplies

Applications

Motor controls
Heating controls
Power supplies

Procurement Notes

Verify the specific Littelfuse datasheet for complete electrical characteristics and thermal derating curves. Confirm that the TO-220AB package dimensions match your PCB footprint requirements. Ensure the 50V rating aligns with your circuit's peak voltage demands.

Selection Notes

Select this component when a low-power SCR is required for half-wave AC regulation. The 8A current rating suits moderate load applications. Verify compatibility with standard gate drive circuits given the 25mA trigger requirement.

Part Context

This part belongs to the MCR218 series of low-power SCRs. The series offers various voltage ratings up to 1200V while maintaining similar current capabilities. The MCR218-2G specifically denotes the 50V variant within this standardized family.

Replacement Considerations

Consult official Littelfuse documentation for confirmed substitute part numbers. Generic equivalents may differ in gate sensitivity or thermal performance.
