Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 3:
Dynamic supply current is higher due to the gate charge may cause permanent damage to the device. Exposure to any Absolute being delivered at the switching frequency. See typical performance Maximum Rating condition for extended periods may affect device characteristics and applications information. reliability and lifetime.
Note 4:
Gate rise times are measured from 2V to 10V, delay times are
Note 2:
TJ is calculated from the ambient temperature TA and power measured from the input transition to when the gate voltage has decreased dissipation PD according to the following formulas: to 10V, and fall times are measured from 10V to 2V.
