2014 Littelfuse, Inc. Specifications are subject to change without notice. Revised: 12/14/14 Teccor brand Thyristors 15 Amp Standard & 16 Amp Alternistor (High Commutation) Triacs 10 100 1000 100 10 1 Surge Current Duration - Full Cycles Peak Surge (Non-Repetitive) On-State Current (I TSM ) - AMPS Figure 10: Surge Peak On-State Current vs. Number of Cycles Supply Frequency: 60Hz Sinusoidal Load: Resistive RMS On-State [I T(RMS) ]: Max Rated Value at Specific Case Temperature Notes: 1. Gate control may be lost during and immediately following surge current interval. 2. Overload may not be repeated until junction temperature has returned to steady-state rated value.
