Power MOSFETs from ON Semi

ON Semiconductor has introduced a new series of power MOSFETs offered in tiny SOT-723 packages and optimized for space-constrained portable applications. These low-threshold power MOSFETs use the company's Trench technology to achieve comparable electrical and power performance to MOSFETs offered in much larger SC-89 or SC-75 packages.

NTK3134N is a 20V, 890mA n-channel MOSFET. The NTK3139P is a -20V, -780mA p-channel MOSFET. Both devices have low Rds(on) values for over 200mA operating current and 1.5V low gate voltage to allow direct control from power management ASIC or other controllers.

The NTK313xx devices are suitable for load/power switching applications and small signal interface switching. Featuring integrated ESD protection, the devices minimize the need for special handling and assembly processes. The 1.2-by-1.2mm footprint of the SOT-723 package uses 44 percent less board space than similar performing MOSFETs offered in the SC-89 or SC-75 packages. With a low vertical clearance of 0.5mm, the SOT-723 packaged MOSFETs satisfy the requirements of new-generation ultrathin handheld portable devices.
