Schematic diagram Assignment Description:
These N-Channel enhancement mode power field effect transistors are produced using silikron
proprietary MOSFET technology. This advanced technology has been especially tailored to
minimize on-state resistance, provide superior switching performance, and withstand high energy
pulse in the avalanche and commutation mode. These devices are well suited for high efficiency
switch mode power supplies

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)=150°C.
⑥ The maximum current rating is limited by bond-wires.
