New Generation 12A and 16A Hi-Com Triacs

The BTA312 and BTA316 series are the latest additions to NXP Semiconductors' range of Hi-Com (three-quadrant) triacs. NXP's new-generation triacs balance the sensitivities in the first and third quadrants (positive and negative load current) to achieve the maximum possible immunity to false triggering at any gate sensitivity.

The BTA312 and BTA316 (12A and 16A) series offer big improvements in dI_com/dt compared to competitors' three-quadrant triacs of similar sensitivity. For example, the BTA312 series C sensitivity, with an I_GT of 35mA, boasts a minimum dI_com/dt of 20A/ms at T_j = +125°C without snubber. This compares with the 6.5A/ms quoted for a competitor's 12A 3Q triac with similar gate sensitivity.



High immunity to false triggering by dV_D/dt, dV_com/dt and dI_com/dt assures performance in circuits with reduced or no protection components. This performance improvement allows further reduction, or complete removal, of the protection components that traditionally were applied to triac circuits. Additionally, the application's reliability also improves because the false triggering and the potentially stressful load current that it causes have reduced.

The triacs offer a full range of gate sensitivities: I_GT = 50mA, 35mA, 10mA or 5mA matches any application requirement. Three package options suit designers' through-hole, isolated and surface mount requirements.
