TQEC46A Datasheet The automatic retriggering prevents half cycles without current flow, even if the triacs is turned off earlier e.g. due to not exactly centred collector (brush lifter) or in the event of unsuccessful triggering. Ifit is necessary, another triggering pulse is generated after a time lapse of tpp = 4.5 tp and this is repeated until either the triac fires or the half cycle finishes. TQEC46A Price co Shipped in plastic bags, 1000 per bag co Available Tape and Reeled, 5000 per reel, by adding a "RL" suffix to the part number co Available in Fan-Fold Packaging, 3000 per box, by adding a "FF" suffix to the part number co These devices are manufactured with a Pb-Free external lead finish only* TQEC46A on stock 1 For a high side switch, the load pin voltage goes negative with respect to ground during the turn-off of an inductive load. This negative voltage is clamped by the device. 2 The load current is self-limited during the response time for short circuit load protection. Response time is measured from when input goes high. 3 If the load resistance is low, but not a complete short circuit, such that the on-state voltage remains less than VBLOO), the device remains in current limiting until the overtemperature protection operates.
