TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN
MOSFET:N-Channel Silicon MOSFET
SBD:Schottky Barrier Diode
DC-DC Converter Applications
Ordering number:EN4895
FX855
Features
· Composite type composed of a ow ON-resistance Nchannel MOSFET for ultrahigh-speed switching and
low-voltage driving and a fast-recovery, low forward
-voltage Schottky barrier diode. Facilitates highdensity mounting.
· The FX855 is formed with 2 chips, one being
equivalent to the 2SK1470 and the other the SB0509, placed in one package.
