Linear derating factor

Power semiconductor devices have a maximum power dissipation rating usually quoted at a case temperature of 25 °C (77 °F). The datasheet for the device also includes a derating curve which indicates how much a device will dissipate without getting damaged at any given case temperature, and this must be taken into account while designing a system. As can be seen from the derating curve image for a hypothetical bipolar junction transistor, the d… Nettet8. mar. 2007 · At case temperatures above 25°C, the linear derating factor is simply the inverse of R θJC.

Nettetdata sheet of 2.25 W and 0.9 W, respectively. A parameter called derating factor can be derived from this. The derating factor is linear, so if the dissipation is 2250 mW for a 100°C rise (from 25°C to 125°C), for each one degree increase in ambient temperature, the power dissipation rating has to be decreased 2250/100 = 22.50 mW/°C.
