Q4040J7TP

Q4040J7TP is a 40Amp alternator (high commutation) and standard triac thyristor. This bi-directional solid state switch series is designed for AC switching and phase control applications such as motor speed, temperature modulation controls, lighting controls, and static switching relays. Alternator type components only operate in quadrants I, II, & III and are used in circuits requiring high dv/dt capability. Standard type devices operate in quadrants I,II,III & IV. Applications include excellent for AC switching and phase control applications such as heating, lighting, and motor speed controls, typical applications are AC solid-state switches, industrial power tools, exercise equipment, white goods and commercial appliances, alternator triacs (no snubber required) are used in applications with extremely inductive loads requiring highest commutation performance, internally constructed isolated packages are offered for ease of heat sinking with highest isolation voltage.
