Product details

Logic-level sensitive-gate triac for 400 VAC line switching

The STMicroelectronics T1210T-8FP is a single, logic-level sensitive-gate triac rated for 800 V off-state voltage and 12 A RMS on-state current. Its 10 mA maximum gate trigger current (Igt) means a microcontroller port can fire it directly through a series resistor — no driver transistor needed.

For dual-sourcing or a higher-current variant, the T1610T-8FP offers 16 A RMS in the same TO-220FP package and same 800 V off-state. The T1210T-8T is the surface-mount sibling in a D²PAK — same die, same ratings, different footprint.

Frequently asked questions

What is the equivalent or replacement for T1210T-8FP?

The T1210T-8T is the surface-mount D²PAK version of the same die — same 800 V, 12 A, sensitive-gate ratings. For a higher-current through-hole alternative, the T1610T-8FP offers 16 A RMS in the same TO-220FP package.

What is the gate trigger current of T1210T-8FP?

The maximum gate trigger current (Igt) is 10 mA, making it a logic-level sensitive-gate triac that can be driven directly from a microcontroller output.
