The SC146 series originated with General Electric's semiconductor line, and SC146D-marked devices have also been catalogued under ON Semiconductor. Littelfuse's Q4010R5 is a current-production 400V, 10A TO-220 TRIAC listed as an equivalent. Before substituting, confirm gate trigger current and voltage, holding current, quadrant operation and dv\/dt requirements against your circuit, since these parameters vary between TRIAC families even at identical voltage and current ratings.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eQ\u0026amp;A\u003c\/strong\u003e\u003cbr\u003eQ: What are the SC146D's ratings? A: 400V repetitive peak off-state voltage and 10A RMS on-state current, in a TO-220AB three-terminal package.\u003cbr\u003eQ: Is there a current-production equivalent? A: Littelfuse's Q4010R5 is a 400V\/10A TO-220 TRIAC listed as a cross-reference — verify gate trigger and dv\/dt specifications before substituting.\u003cbr\u003eQ: What is a TRIAC used for?
