Diode Forward Voltage versus CurrentSAFE OPERATING AREA The Forward Biased Safe Operating Area curves define reliable operation, the stored energy from circuit inductance the maximum simultaneous drain−to−source voltage and dissipated in the transistor while in avalanche must be less drain current that a transistor can handle safely when it is than the rated limit and adjusted for operating conditions forward biased. Curves are based upon maximum peak differing from those specified. Although industry practice is junction temperature and a case temperature (TC) of 25°C. to rate in terms of energy, avalanche energy capability is not Peak repetitive pulsed power limits are determined by using a constant. The energy rating decreases non−linearly with an the thermal response data in conjunction with the procedures increase of peak current in avalanche and peak junction discussed in AN569, “Transient Thermal temperature.
