BSS138LT1
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): 0.5 V−1.5 V) Makes it Ideal for
Low Voltage Applications
• Miniature SOT−23 Surface Mount Package Saves Board Space
• Pb−Free Packages are Available
