Power MOSFET
4.2A, 20V P-CHANNEL
POWER MOSFET
DESCRIPTION
The UTC UT2305 is P-channel enhancement mode power
MOSFET, designed in serried ranks. With fast switching speed, low
on-resistance, favorable stabilization.
Used in commercial and industrial surface mount applications
and suited for low voltage applications such as DC/DC converters.
