6. Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient temperature as possible.
7. 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.
8. NCV prefix is for automotive and other applications requiring site and change control and extended operating temperature conditions.
