2014 Littelfuse, Inc. Specifications are subject to change without notice. Revised: 12/14/14 Teccor brand Thyristors AN1002 Examples of a 10 A Triac: If I GT (I) = 10 mA, then I GT (II) = 15 mA I GT (III) = 14 mA I GT (IV) = 31 mA If I L (I) = 16 mA, then I L (II) = 40 mA I L (III) = 18 mA I L (IV) = 20 mA If I H (+) = 11 mA at 25 C, then I H (+) = 16 mA Gating, latching, and holding current characteristics of Thyristors are quite important yet predictable (once a single parameter value is known). Their interrelationships (ratios) can also be used to help designers in both initial circuit application design as well as device selection.
