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 MAXIMUM RATINGS — continued Rating Forward Peak Gate Power (t = 10 µs) Forward Average Gate Power Symbol Value Unit PGM 5 Watts PG(AV) 0.5 Watt IGM 2 Amps TJ –40 to +100 °C Tstg –40 to +125 °C Symbol Max Unit RθJC 1.8 °C/W Forward Peak Gate Current Operating Junction Temperature Range Storage Temperature Range THERMAL CHARACTERISTICS Characteristic Thermal Resistance, Junction to Case ELECTRICAL CHARACTERISTICS (TC = 25°C unless otherwise noted.)
