ON Semiconductor Expands Low Vce(sat) BJT Portfolio

July 05, 2007 by Jeff Shepard

ON Semiconductor has expanded its low Vce(sat) bipolar junction transistors (BJTs) portfolio to include PNP and NPN devices that incorporate advanced silicon technology. These new transistors are claimed to deliver maximized power efficiency and longer battery life than traditional BJTs or planar MOSFETS. Suitable for a variety of portable applications, the new low Vce(sat) BJTs are available in multiple package options, including WDFN, SOT-23, SOT-223, SOT-563, ChipFET and SC-88.

"ON Semiconductor offers the widest selection of high performance BJTs on the market today," said Mamoon Rashid, Vice President and General Manager of ON Semiconductor’s Discrete Products Division. "Our Low Vce(sat) BJTs are leaders in power loss and thermal performance providing very economic solutions for power control. These devices are strategic switches in products from mobile phones to automobiles providing cost effective solutions designers need to keep their products at the leading edge."

The company’s new NSSxxx low Vce(sat) surface mount devices are specifically designed for use in low voltage switching applications where energy efficient control is vital. They feature ultra-low saturation voltage – 45mV at 1A – and high current gain – 300. Offering a high electrostatic discharge (ESD) tolerance of greater than 8,000V, these Low Vce(sat) BJTs are self-protecting against unexpected surges and damage. According to the company, by providing "superior electrical performance" and low temperature coefficient, they improve power efficiency and ultimately, battery power conservation without the need for additional ESD protection circuits. The medium switching speeds provide lower noise harmonics than MOSFETS and are therefore more suited to applications where Electro Magnetic Interference has to be controlled.

The low Vce(sat) BJT series is available in a wide variety of industry leading packages, including SOT-23, SOT-223, SOT-563, WDFN3, WDFN6, ChipFET, SC-88, SC74, TSOP6. They are priced between $0.14 to $0.27 USD per unit for quantities of 10,000 units.
