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
R
θJA
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 T
J(MAX)
=175°C.
