Product details

12 A RMS SCR for line-voltage switching

It is designed for phase-control applications such as motor speed drives, industrial heating, lighting dimmers, and AC power switching where a robust thyristor is needed. The 5 mA maximum gate trigger current allows direct drive from low-power logic or optocoupler circuits without an extra driver stage.

For high-reliability or high-vibration installations, use a thermal compound and a clip or screw mount to the heatsink.

No successor or replacement has been announced.

Frequently asked questions

Is TYN612TRG RoHS compliant?

Yes, the TYN612TRG is ROHS3 compliant.

Can TYN612TRG replace TYN612?

The TYN612TRG is the same base product (TYN612) with a specific packaging and reel suffix. It is functionally identical to other TYN612 variants in the same package. For a direct replacement, verify the package and temperature grade match your BOM.
