Low-Voltage FETs reduce Losses to Meet Demand for Greater Efficiency

ON Semiconductor Corp. introduced during PCIM Europe a new family of six 25V N-channel MOSFETs that have been designed and optimized to deliver industry leading efficiency compared to existing devices on the market. The new NTMFS4Hxxx and NTTFS4Hxxx series of MOSFETs are suited as switching devices for a wide range of applications including server and networking equipment and high power density dc-dc converters, or to support synchronous rectification in point-of-load (PoL) modules. Versions of these MOSFETS are available with or without an integrated Schottky diode that can help engineers achieve even greater efficiency.

ON Semiconductor recognizes the ever-increasing focus on the energy efficiency of end product performance, and has optimized the design, materials and packaging of the new power MOSFETs to reduce losses. Best-in-class RDSon performance of 0.7 milliohms (mΩ) and low input capacitance of 3780 picofarads (pF) ensure conduction, switching and driver losses are minimized. Careful consideration has also been given to ensure that the MOSFETs offer improved thermal performance and low package resistance and inductance compared to existing devices.

"Optimal overall efficiency derived from minimizing losses incurred through conduction and switching is very high on the wish list for designers across an increasing number of end markets," said Paul Leonard, vice president and general manager for ON Semiconductor's Power Discrete products. "By utilizing our process, materials and packaging expertise we have been able to advance the performance of power MOSFETs to a new level that will help our customers achieve their stringent design performance objectives."

The NTMFS4H01N, NTMFS4H01NF, NTMFS4H02N and NTMFS4H02NF are offered in Pb-free S08-FL packages and priced at $2.99, $3.06, $1.86 and $1.93 per unit respectively in 1,500 unit quantities while the NTTFS4H05N and NTTFS4H07N are offered in Pb-free µ8-FL packages and priced at $0.86 and $0.67 per unit in 1,500 unit quantities.
