Product details

What this Alternistor does — and what it saves you

The ST BTA06-600BWRG is a Snubberless™ Alternistor triac rated for 600 V off-state and 6 A RMS on-state current in a TO-220 through-hole package. The Snubberless construction means the internal die is designed to commutate inductive loads without an external RC snubber network — you can drop the snubber resistors and capacitors from the BOM for motor drives, heater controls, and solid-state relay outputs up to 6 A. Triggering at a maximum 50 mA gate current and 1.3 V gate voltage keeps the drive compatible with standard logic-level transistors or an MCU GPIO with a series resistor. The industrial temperature range (-40°C to 125°C junction) suits panel-mount applications in factory automation, HVAC damper drives, and commercial cooking equipment where the triac sees conducted heat from the load or enclosure. The single-triac configuration in a TO-220 means one mounting screw and a standard heatsink pad — no extra isolation hardware beyond the usual mica washer and bushings.

Frequently asked questions

What is BTA06-600BWRG?

BTA06-600BWRG is a Snubberless™ Alternistor triac from STMicroelectronics, rated 600 V off-state and 6 A RMS on-state, in a TO-220 through-hole package. It is designed for AC load switching without an external snubber network.

What is the difference between BTA06 and BTB06?

The BTA06 and BTB06 share the same Snubberless Alternistor die and 6 A / 600 V rating. The difference is package isolation: BTA06 uses an isolated TO-220 tab (no internal connection to the die), while BTB06 has the tab internally connected to the MT2 terminal. For a common heatsink, the BTA06 avoids an isolation washer.

What is Snubberless TRIAC?

Snubberless is ST's trademark for Alternistor triacs designed to commutate inductive loads without an external RC snubber network. The internal die structure handles the rate-of-rise of voltage (dV/dt) during turn-off, reducing BOM count and board space.

What is the equivalent of BTA06-600BWRG?

The functional equivalent within the same Snubberless series is the BTA06-800BWRG, which has an 800 V off-state rating instead of 600 V. The BTB06-600BWRG shares the same voltage and current rating but has a non-isolated tab. The BTA08-800BWRG is an 8 A / 800 V variant in the same package. None of these are pin-for-pin second-sources; verify the voltage, current, and isolation requirement for your application.
