ENHANCEMENT MODE FIELD
EFFECT TRANSISTOR

DESCRIPTION
The UTC UD4840-H is a dual N-Channel enhancement mode
field effect transistor, it uses UTC’s advanced technology to provide
customers with a minimum on-state resistance and low gate charge,
etc.
The UTC UD4840-H is suitable for use as a load switch or in
PWM applications.

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 board design.
The current rating is based on the t≤10s thermal resistance rating.
2. Repetitive rating, pulse width limited by junction temperature.
3. The θJA is the sum of the thermal impedence from junction to lead θJL and lead to ambient.
