Elektronische Bauelemente
Dual N-Channel Mode Power MOSFET
4.4 A, 40 V, R
DS(ON)
75 m
RoHS Compliant Product
A suffix of “-C” specifies halogen & lead-free
DESCRIPTION
These miniature surface mount MOSFETs
utilize a high cell density trench process to
provide low R
DS(on)
and to ensure minimal
power loss and heat dissipation. Typical
applications are DC-DC converters and power
management in portable and battery-powered
products such as computers, printers, PCMCIA
cards, cellular and cordless telephones.
