UF3N20
Preliminary
Power MOSFET
3A, 200V N-CHANNEL
POWER MOSFET

DESCRIPTION
The UTC UF3N20 is an N-channel mode power MOSFET
using UTC’s advanced technology to provide customers with
planar stripe and DMOS technology. This technology allows a
minimum on-state resistance and superior switching performance.
It also can withstand high energy pulse in the avalanche and
commutation mode.
The UTC UF3N20 is generally applied in high efficiency switch
mode power supplies, active power factor correction and
electronic lamp ballasts based on half bridge topology.

FEATURES
* RDS(ON) < 200mΩ @ VGS=10V, ID=1.5A
* High switching speed
* 100% avalanche tested

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. Repetitive Rating : Pulse width limited by TJ.
3. L=55mH, IAS=2.0A, VDD=50V, RG=25 Ω, Starting TJ = 25°C
4. ISD ≤ 2.4A, di/dt ≤ 200A/μs, VDD ≤ BVDSS, Starting TJ = 25°C
