Ratings apply for zero or negative gate voltage; however, 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. (2) Ratings apply for tw = 1 ms. See Figure 1 for ITM capability for various duration of an exponentially decaying current waveform, t w is defined as 5 time constants of an exponentially decaying current pulse. (3) Test Conditions: IG = 150 mA, VD = Rated VDRM, ITM = Rated Value, TJ = 125°C. 1 Device Package Shipping MCR69–2 TO220AB 500/Box MCR69–3 TO220AB 500/Box MCR69–2, MCR69–3 THERMAL CHARACTERISTICS Symbol Max Unit Thermal Resistance, Junction to Case Characteristic RθJC 1.5 °C/W Thermal Resistance, Junction to Ambient RθJA 60 °C/W TL 260 °C Maximum Lead Temperature for Soldering Purposes 1/8″ from Case for 10 Seconds ELECTRICAL CHARACTERISTICS (TC = 25°C unless otherwise noted.)
