Thyristors 25 Amp Standard & Alternistor (High Commutation) Triacs RoHS Qxx25xx & Qxx25xHx Series Description This 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 alternistor triac components operate with in- phase signals in Quadrants I or III and ONLY unipolar negative gate pulses for Quadrant II or III. The alternistor triac will not operate in Quadrant IV. Features & Benefits R oHS compliant Surge capabilit y up to 250A at 60 Hz Glass passivated half cycle junctions Agency Approval V oltage capability up Agency Agency File Number to 1000 V E71639* * - Only Package Types TO-220L, TO-218K and TO-218J 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 Main Features power tools, exercise equipment, white goods and commercial appliances. Symbol Value Unit Alternistor Triacs (no snubber required) are used in I 25 A T(RMS) applications with high inductive loads requiring the highest V /V 1000 V DRM RRM commutation performance. I 50 or 80 mA GT Internally constructed isolated packages are offered for ease of heat sinking with highest isolation voltage.
