ON Semiconductor Introduces New SOT-723 Packaged Power MOSFETs for Space-Constrained Portable Electronics

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

The 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 200 mA 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 minimize the need for special handling and assembly processes. The 1.2mm x 1.2mm footprint of the SOT-723 package utilizes 44% 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 new SOT-723 packaged MOSFETs satisfy the requirements of new generation ultra-thin handheld portable devices.

Both devices are currently in production and available. They are priced at $0.13 USD per unit in 10,000 unit quantities.
