Analog Power
BSS138N
N-Channel 50-V (D-S) MOSFET
These miniature surface mount MOSFETs
utilize High Cell Density process. Low
rDS(on) assures minimal power loss and
conserves energy, making this device ideal
for use in power management circuitry.
Typical applications are DC-DC
converters, power management in portable
and battery-powered products such as
computers, printers, PCMCIA cards,
cellular and cordless telephones.
