UT4414
Power MOSFET
N-CHANNEL ENHANCEMENT
MODE FIELD EFFECT
TRANSISTOR

DESCRIPTION
The UTC UT4414 is an N-channel enhancement mode FET with
excellent trench technology to provide customers perfect RDS(ON) and
low gate charge. The source leads are separated to allow a Kelvin
connection to the source, which may be used to bypass the source
inductance.
This device can be applied in a load switch or in PWM
applications.

FEATURES
* VDSS = 30V
* ID=8.5A @VGS=10V
* RDS(ON) < 26mΩ @ VGS=10V,ID=8.5A
* RDS(ON) < 40mΩ @ VGS=4.5V, ID=5A

Notes: 1. The value of θJA is measured with the device mounted on 1in2 FR-4 board with 2oz. Copper, in a still air
environment with TA=25°C. The value in any given application depends on the user's specific boar design.
The current rating is based on the t ≤ 10s thermal resistance rating.
2. Repetitive Rating : Pulse width limited by TJ.
3. The θJA is the sum of the thermal impedance from junction to lead θJL and lead to ambient.
