Product details

Logic-level triac for low-power AC switching

The WeEn BTA2008-800E,412 is a single logic-level (sensitive gate) triac in a through-hole TO-92-3 package. It switches AC loads up to 800 mA RMS at 800 V off-state, with a maximum gate trigger current of 10 mA and a gate trigger voltage of 2 V. The low Igt lets a microcontroller GPIO or optocoupler drive it directly, eliminating the driver transistor and saving board space in small appliances, fan speed controllers, and solid-state relay front-ends. The 125°C junction temperature rating suits enclosed or warm environments like a motor-start circuit or a lighting ballast.

It is a current-production part, not an obsolete or NRND line. For dual-sourcing resilience, the standard TO-92-3 sensitive-gate triac footprint is shared across several manufacturers (e.g., STMicroelectronics, Littelfuse, NXP legacy parts); a pin-compatible alternate can be qualified without a board respin.

Frequently asked questions

What is the gate trigger current (Igt) of BTA2008-800E?

The maximum gate trigger current (Igt) is 10 mA, and the maximum gate trigger voltage (Vgt) is 2 V. These low values allow direct drive from a 5 V logic output through a current-limiting resistor.

Is BTA2008-800E a logic-level (sensitive gate) triac?

Yes, the BTA2008-800E is a logic-level (sensitive gate) triac, meaning it can be triggered directly by low-voltage logic signals without an intermediate driver transistor.

What is the replacement or equivalent for BTA2008-800E?

The BTA2008-800E is an active part with no official successor. For a second source, look for a TO-92-3 sensitive-gate triac with 800 V off-state and 800 mA RMS rating from STMicroelectronics or Littelfuse – the footprint and pinout are standard across the industry.
