onsemi NTK3139P P-Channel Single Power MOSFET

onsemi NTK3139P P-Channel Single Power MOSFET is available in a compact SOT-723 package with built-in ESD protection. The SOT-723 package has a 44% smaller footprint and is 38% thinner than an SC-89 package. The drain-to-source voltage (VDSS) is rated at -20V and has a continuous drain current (ID) rating of -780mA (TA = +25°C). The onsemi NTK3139P features a low threshold level allowing for a 1.5V RDS(on) rating (VGS = 1.5V, ID = -100mA) of 0.95Ω (typical). The onsemi device can be operated at a low logic level gate drive. Typical applications include load/power switching, interfacing (logic switching), and battery management for ultra-small portable electronics.
