The Alternistor structure provides commutating dv/dt immunity that eliminates the external RC snubber normally required when switching inductive loads like small motors, solenoids, or transformer primaries. With a 35 mA maximum gate trigger current and 1.3 V maximum gate trigger voltage, the device can be driven directly from a microcontroller I/O pin through a current-limiting resistor — no additional driver transistor needed for most 5 V logic families. ## Surge handling and thermal budget The 35 mA maximum holding current ensures the triac stays latched at low load currents, preventing premature turn-off in lightly loaded circuits. ## Package and mounting for power dissipation Housed in a standard TO-220-3 through-hole package (supplier device package TO-220), the BTA12-600CWRG mounts to a heatsink via the metal tab — the tab is electrically isolated from the die but must be considered for creepage and clearance in the PCB layout. The through-hole leads handle the 12 A RMS current without additional thermal relief on the copper pour. ## Lifecycle and compliance status ROHS3 compliant, so it meets EU RoHS exemption requirements for lead-free soldering processes without additional documentation burden.","metaTitle":"STMicroelectronics BTA12-600CWRG Triac, 12 A, 600 V","metaDescription":"STMicroelectronics BTA12-600CWRG Snubberless™ triac, 12 A RMS, 600 V off-state, TO-220-3.
