Power MOSFET
200 mA, 50 V
N−Channel SOT−23
Typical applications are DC−DC converters, power management in
portable and battery−powered products such as computers, printers,
PCMCIA cards, cellular and cordless telephones.
Features
•Low Threshold Voltage (VGS(th): 0.85 V−1.5 V) Makes it Ideal for
Low Voltage Applications
•Miniature SOT−23 Surface Mount Package Saves Board Space
•BVSS Prefix for Automotive and Other Applications Requiring
Unique Site and Control Change Requirements; AEC−Q101
Qualified and PPAP Capable
•These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS
Compliant
