N-channel Trench MOSFETs

ON Semiconductor’s new MOSFETs feature optimized low gate charge and RDS(on) to improve switching performance and overall system efficiency in an advanced packaging portfolio.

New NTD49xx, NTMFS49x, NTTFS49x and NTMS49x series of 30 volt, N-channel devices improve switching performance and overall power efficiency

Phoenix, AZ – Oct. 26, 2009 - ON Semiconductor (Nasdaq: ONNN) has introduced 24 new 30 volt (V), N-channel Trench MOSFETs in DPAK, SO-8FL, µ8FL and SOIC-8 packages featuring enhanced switching performance for synchronous buck converters in computing and game console applications.

The new series of MOSFETs utilize ON Semiconductor’s Trench technology to deliver on-state resistance [RDS(on)] and improved switching performance for synchronous DC-to-DC converters in PC, server, game console, VRM and point-of-load applications. 

DPAK, SO-8FL and SOIC-8 package solutions – which are a drop-in replacement for NTD48x, NTMFS48x and NTMS48x series – and the new µ8FL 3.3 mm x 3.3 mm solution achieve low RDS(on) in relation to packaging size.

“Power management design engineers in the computing and gaming segments can improve overall efficiency by using ON Semiconductor’s newest 30 volt Trench MOSFET solutions,” says Paul Leonard, ON Semiconductor vice president and general manager of Power MOSFET products.

ON Semiconductor’s new MOSFETs feature optimized low gate charge and RDS(on) to improve switching performance and overall system efficiency in an advanced packaging portfolio.  All devices are lead-free (Pb-free), Halogen free and RoHs compliant.
