The GATE pin has internal clamping circuits to prevent the GATE pin voltage

from exceeding the maximum ratings of a MOSFET with VGSMAX = 20 V and

internal process limits. Applying a voltage source to this pin externally may

cause irreversible damage.

Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. This is a stress

rating only; functional operation of the device at these or any

other conditions above those indicated in the operational

section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device reliability.

THERMAL CHARACTERISTICS

θJA is specified for the worst-case conditions, that is, a device

soldered in a circuit board for surface-mount packages.
