Active production, sensitive gate, TO-92 package
The NXP BTA2008-800D,412 is an active-production sensitive-gate triac in a TO-92 through-hole package. It switches AC loads up to 800 mA RMS with an off-state voltage rating of 800 V, making it suitable for low-power phase control and on/off switching in compact, cost-sensitive designs.
Gate trigger and hold current — what they mean for the driver circuit
Maximum gate trigger current is 5 mA and maximum gate trigger voltage is 2 V — a logic-level output from a microcontroller or a low-power transistor can drive this triac directly without a separate driver stage. The 10 mA maximum hold current means the triac stays latched once triggered as long as the load current stays above that threshold; below it the device commutates off at the next zero-crossing.
Surge capability and junction temperature
Non-repetitive surge current is rated 9 A at 50 Hz and 10 A at 60 Hz — this covers inrush from incandescent lamps, capacitive loads, or motor start-up within the device's SOA. Maximum operating junction temperature is 125 °C, so the triac can be used in enclosed or moderately warm environments without derating the RMS current below 800 mA.
Through-hole assembly and package options
Supplied in a TO-226-3 / TO-92-3 package with formed leads, the device is suited for wave-solder assembly on single-sided or double-sided PCBs. The bulk packaging suits high-volume pick-and-place with tube or tray feeders; for reeled tape, confirm the alternative order code with your distributor.
