6 A RMS at 800 V — load-switching capacity for AC line control
The NXP BTA206-800CT,127 is a standard triac rated for 6 A RMS continuous on-state current with an 800 V off-state blocking voltage, making it suitable for medium-power AC switching in resistive or inductive loads like heaters, small motors, and solenoid valves. Non-repetitive surge capability of 60 A at 50 Hz and 66 A at 60 Hz means the device can handle inrush from lamp filaments or motor start currents without failing, provided the surge duration stays within the half-cycle window.
Gate drive margin and holding current for reliable commutation
Maximum gate trigger current of 35 mA and gate trigger voltage of 1.5 V define the drive requirement — a standard logic-level or optocoupler output can fire this triac without a separate driver stage, as long as the pulse exceeds these thresholds across temperature. The 35 mA maximum holding current means the device stays latched once triggered until the load current drops below that level near the AC zero-crossing, which is typical for standard triac commutation in 50/60 Hz circuits.
Through-hole TO-220AB package for board-level power dissipation
Housed in a TO-220-3 through-hole package with the supplier device package designated TO-220AB, the BTA206-800CT,127 mounts directly into a PCB or heatsink — the metal tab provides the thermal path, so the junction-to-ambient thermal resistance depends on the heatsink area and airflow in the enclosure. Rated for a maximum junction temperature of 150 °C, the triac's continuous current derates above 25 °C; a heatsink with adequate surface area is required to stay within the SOA at the full 6 A RMS load.
Active production — no obsolescence concern for new designs
NXP lists the BTA206-800CT,127 as Active in production, so it remains available for both new designs and ongoing production without a last-time-buy window or successor migration risk.
