VDRM and VRRM for all types can be applied on a continuous basis. Ratings apply for zero or negative gate voltage; however, (cont.) positive gate voltage shall not be applied concurrent with negative potential on the anode. Blocking voltages shall not be tested with a constant current source such that the voltage ratings of the devices are exceeded. 36 Motorola Thyristor Device Data C122( )1 Series MAXIMUM RATINGS -- continued Rating Forward Peak Gate Power (t = 10 s) Forward Average Gate Power Forward Peak Gate Current Operating Junction Temperature Range Storage Temperature Range Symbol PGM PG(AV) IGM TJ Tstg Value 5 0.5 2 -40 to +100 -40 to +125 Unit Watts Watt Amps C C THERMAL CHARACTERISTICS Characteristic Thermal Resistance, Junction to Case Symbol RJC Max 1.8 Unit C/W ELECTRICAL CHARACTERISTICS (TC = 25C unless otherwise noted.)
