Power MOSFET
20V, 3.5A P-CHANNEL
ENHANCEMENT MODE FIELD
EFFECT TRANSISTOR

DESCRIPTION
The UTC UT3419 is a P-channel enhancement MOSFET
providing designers with excellent RDS(ON), low gate charge. The
gate voltage is as low as 2.5V.
The UTC UT3419 can be applied in PWM applications or used
as a load switch.

FEATURES
* RDS(ON) < 75mΩ (VGS = -10V)
RDS(ON) < 95mΩ (VGS = -4.5V)
RDS(ON) < 145mΩ (VGS = -2.5V)

Notes: 1. The value of θJA is measured with the device mounted on 1in FR-4 board with 2oz. Copper, in a still air
environment with TA =25°C. The value in any a given application depends on the user's specific board
design. The current rating is based on the t ≤ 10s thermal resistance rating.
2. Repetitive rating, pulse width limited by junction temperature.

Notes: 1. The θJA is the sum of the thermal impedance from junction to lead θJL and lead to ambient.
2. These tests are performed with the device mounted on 1 in2 FR-4 board with 2oz. Copper, in a still air
environment with TA=25°C. The SOA curve provides a single pulse rating.
