| Market Reality | This is the triac row behind dimmers, speed controllers, heater regulators and every mains switch built in the last forty years: the BT13x series from 4A to 16A and the BTA/BTB 16-40A generation, all in TO-220 bodies that differ in ways the eye cannot see. Two laws govern the family. The prefix encodes the tab: BTA is the isolated-tab part that bolts straight to a grounded heatsink, BTB is the non-isolated one that needs an insulating pad. And the suffix encodes drive class and voltage: sensitive-gate D/E grades trigger from logic-level currents where the snubberless B/A grades demand tens of milliamps. Every substitution along this row is one of those two letters read wrong. | This is the triac row behind dimmers, speed controllers, heater regulators and every mains switch built in the last forty years: the BT13x series from 4A to 16A and the BTA/BTB 16-40A generation, all in TO-220 bodies that differ in ways the eye cannot see.
