UF640-P
Power MOSFET
18A, 200V, 0.18OHM,
N-CHANNEL POWER MOSFET

DESCRIPTION
These kinds of n-channel power MOSFET field effect
transistor have low conduction power loss, high input
impedance, and high switching speed, Linear Transfer
Characteristics, so can be use in a variety of power conversion
applications.
