It switches AC loads without an external RC snubber in many inductive applications — the Alternistor structure handles the commutation dV/dt internally. The TO-220-3 package fits standard through-hole mounting, with the tab tied to the MT2 terminal for heatsinking. The 800 V off-state rating gives headroom for 230 VAC mains (peak ~325 V) and even 400 VAC three-phase lines (peak ~565 V). The 16 A RMS on-state current is the continuous load limit — derate for ambient temperature above 25 °C and for heatsink thermal resistance. The 35 mA gate trigger current (Igt max) is compatible with standard MCU-driven optotriac or logic-level drivers; the 35 mA holding current (Ih max) means the triac stays latched above that load current. It is ROHS3 compliant. At the high end, the 16 A rating must be derated per the datasheet curve — the tab temperature, not the ambient, sets the limit. The TO-220 package allows bolt-on or clip-on heatsinking for continuous loads above a few amps.","metaTitle":"STMicroelectronics BTA16-800CWRG Triac, 800 V, 16 A, TO-220","metaDescription":"ST BTA16-800CWRG Snubberless Alternistor triac: 800 V off-state, 16 A RMS, TO-220-3, -40°C to 125°C.

The BTA16-800CW is a standard triac in the same voltage and current class. The Alternistor version has higher commutation dV/dt capability, which reduces the need for an external snubber on inductive loads.
