Power MOSFETs suit space-constrained apps

Keywords:ON Semiconductor  power MOSFETs  NTK3134N  NTK3139P 

ON Semiconductor has introduced a generation of power MOSFETs offered in tiny SOT-723 packages and optimised for space-constrained portable applications. These low threshold power MOSFETs utilise ON Semiconductor's leading-edge 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 electrostatic discharge (ESD) protection the devices minimise the need for special handling and assembly processes. The 1.2-by-1.2mm footprint of the SOT-723 package utilises 44 per cent 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 ultra-thin handheld portable devices.
