NTUD312x devices offer a 30 percent smaller mount area than comparable MOSFET solutions offered in single SOT-723 package and 60 percent smaller than SOT-563 MOSFETs

PHOENIX, Ariz. – April 16, 2008 - ON Semiconductor (Nasdaq: ONNN), a global leader in efficient power solutions, introduced three new dual MOSFETs offered in an ultra-small SOT-963 package and optimized for space-constrained portable electronics. Measuring 1.0 mm x 1.0 mm, the SOT-963 offers 30 percent smaller mount area than comparable MOSFET solutions offered in a single SOT-723 package and a 60 percent smaller footprint than SOT-563 devices. With a low vertical clearance of 0.5 mm, the new SOT-963 packaged NTUD312x devices satisfy the requirements of the new generation ultra-thin handheld portable devices.

The NTUD312x devices have On-Resistance values rated at 1.5 volt (V) gate to source to enable operation at low voltage logic level. NTUD3127C is a 20 V, 200 milliampere (mA) / -180 mA complementary small signal MOSFET. The NTUD3128N is a 20 V, 200 mA Dual N-Channel MOSFET. The NTUD3129P is a -20 V, -180 mA Dual P-Channel MOSFET.

Budgetary pricing for these devices is $ 0.33 USD per unit in 8,000 unit quantities. For additional information, visit https://www.onsemi.com or contact Sam Abdeh at sam.abdeh@onsemi.com.
