UT4435
Power MOSFET
-8.8A, 30V P-CHANNEL
POWER MOSFET

DESCRIPTION
The UT4435 uses advanced trench technology to provide
excellent RDS(ON), low gate charge and operation with low gate
voltages. This device is suitable for use as a load switch or in
PWM applications.

Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. Pulse Test: Pulse Width < 300μs, Duty Cycle < 2.0%.
3. θJA is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal
reference is defined as the solder mounting surface of the drain pins. θJC is guaranteed by design while θJA
is determined by the user's board design.
