Product details

6 A RMS, 800 V off-state — AC load switching in a TO-220

The STMicroelectronics T610T-8T is a logic-level triac rated for 6 A RMS on-state current and 800 V off-state voltage, housed in a TO-220 through-hole package. The sensitive gate (10 mA max Igt) allows direct triggering from a microcontroller or ASIC I/O without an external driver transistor.

Surge and gate drive margins

Non-repetitive surge current is 45 A at 50 Hz and 47 A at 60 Hz — this covers the inrush from incandescent lamp loads or capacitive power supplies without exceeding the device's peak current capability. Maximum gate trigger voltage is 1.3 V, and the hold current is 15 mA max.

Frequently asked questions

Where can I buy T610T-8T and how do I get a price?

The T610T-8T is sourced to order against your BOM quantity.

What is the closest functional second-source to T610T-8T?

The T810T-8T is the 8 A RMS sibling in the same TO-220 package, same 800 V off-state voltage, same logic-level gate sensitivity. It drops into the same footprint and gate drive circuit, offering a higher current ceiling if the load requires it.
