Product details

Snubberless alternistor for inductive loads

The STMicroelectronics BTA16-600BW is a Snubberless™ alternistor triac rated for 600 V off-state voltage and 16 A RMS on-state current. The TO-220 through-hole package handles the dissipation with a simple heatsink — no thermal pad complexity.

Sourcing this part now

The BTA16-600BW is listed as obsolete. For new designs, consider the active BTA16-600CW or BTA41-600BRG as drop-in candidates with identical 600 V / 16 A ratings and Snubberless behaviour.

Gate drive and surge margin

Maximum gate trigger current is 50 mA and gate trigger voltage is 1.3 V — compatible with standard logic-level drivers or optocoupler outputs. The 50 mA holding current ensures reliable latching in noisy environments. Non-repetitive surge capability is 160 A at 50 Hz and 168 A at 60 Hz, sized for lamp inrush or motor start transients.

Frequently asked questions

What is the direct replacement for BTA16-600BW?

No official direct replacement is listed, but the BTA16-600CW and BTA41-600BRG are functionally equivalent Snubberless triacs in the same TO-220 package with identical 600 V off-state voltage and 16 A RMS current rating. Verify gate trigger and holding current against your design.

Can BTA16-600BW be used as a snubberless triac replacement?

Yes, the BTA16-600BW is itself a Snubberless™ alternistor triac. It is designed for inductive loads without external snubber components, relying on internal dV/dt immunity to prevent false triggering.
