2014 Littelfuse, Inc. Specifications are subject to change without notice. Revised: 12/14/14 Teccor brand Thyristors 25 Amp Standard & Alternistor (High Commutation) Triacs Qxx25xx & Qxx25xHx Series Description 25 Amp bi-directional 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. Standard type devices normally operate in Quadrants I & III triggered from AC line. and are used in circuits requiring high dv/dt capability. Features & Benefits junctions to 1000 V to 250 A Main Features Symbol Value Unit I T(RMS) 25 A V DRM /V RRM 1000 V I GT 50 to 80 mA Schematic Symbol MT2 MT1 G Agency Approval Agency Agency File Number TO-220L, TO-218K, TO-218J & Fastpak Packages: E71639 Applications 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. Alternistor 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. RoHS Additional Information Datasheet Samples Resources
