1 Selected Packages* U.L. RECOGNIZED File #E7139 THERMOTAB TO-AB (Isolated) MT MT1 T QUADRACs Internally Triggered Triacs ( 15 Amps) 3 General Description Teccor s QUADRAC is a triac that includes a diac trigger mounted inside the same package. This device, developed by Teccor, saves the user the expense and assembly time of buying a discrete diac and assembling in conjunction with a gated triac. The QUADRAC is a bidirectional AC switch and is gate controlled for either polarity of main terminal voltage. Its primary purpose is for AC switching and phase control applications such as speed controls, temperature modulation controls, and lighting controls. Triac current capacities range from to 15 Amperes with voltage ranges from -. QUADRACs are available in the TO- AB package as shown above. The Thermotab package is electrically isolated to,5 V (RMS) from the leads to mounting surface., V (RMS) available on special order. This means that no external isolation is required, thus eliminating the need for separate insulators and insulatormounting steps... saving dollars over hot tab devices. All Teccor triac and diac chips have glass-passivated junctions to ensure long term device reliability and parameter stability. Variations of devices in this data sheet are available for custom design applications. Please consult the factory for more information.
