Test Circuits and Waveforms
Switch Waveforms:
Notes:
①The maximum current rating is limited by bond-wires.
②Repetitive rating; pulse width limited by max. junction temperature.
③The power dissipation PD is based on max. junction temperature, using junction-to-case thermal
resistance.
④The value of RθJA is measured with the device mounted on 1in 2 FR-4 board with 2oz. Copper, in a
still air environment with TA =25°C
⑤These curves are based on the junction-to-case thermal impedence which is measured with the
device mounted to a large heatsink, assuming a maximum junction temperature of TJ(MAX)=175°C.
⑥ Calculated continuous current based on maximum allowable junction temperature. Package
limitation current is 75A
