Thyristors 25 Amp High Temperature Alternistor Triacs RoHS QJxx25xHx Series Description This 25A alternistor triac solid state switch series is designed for AC switching and phase control applications such as motor speed and temperature modulation controls, lighting controls, and static switching relays. Alternistor TRIAC components only operate in Quadrants I, II, & III and are used in circuits requiring high dv/dt capability. Features & Benefits Agency Approvals Agency Agency File Number V oltage capability up to R ecognized to UL 1557 600V as an Electrically Isolated E71639* Semiconductor Devices Surge capabilit y of 250A * - J, K and L Packages at 60Hz half cycle Halogen-free and RoHS-compliant Main Features Symbol Value Unit I 25 A T(RMS) Applications V /V 400,600, or 800 V DRM RRM Excellent for AC switching and phase control applications I 35 to 80 mA GT such as heating, lighting, and motor speed controls. Typical applications are AC solid-state switches, industrial power tools, exercise equipment, white goods and Schematic Symbol commercial appliances. Alternistor Triacs (no snubber required) are used in applications with high inductive loads requiring the highest MT2 MT1 commutation performance. Internally constructed isolated package are offered for ease of heat sinking with highest isolation voltage. G 2019 Littelfuse, Inc Specifications are subject to change without notice.
