5. Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient temperature as possible.
6. The V IPK(Sense) Current Limit Sense Voltage is specified at static conditions. In dynamic operation the sensed current turn ? off value depends
on comparator response time and di/dt current slope. See the Operating Description section for details.
7. NCV prefix is for automotive and other applications requiring site and change control.
