Intersil’s 75 Volt N-Channel UltraFET™ Delivers Power Efficiency To Automotive 42 Volt Battery Applications

PALM BAY, FL, December 10, 1999 — Intersil Corporation today announced its first power MOSFET specifically designed for automotive 42 volt (V) battery applications. The company’s new 75V UltraFET features 10 milliohm on-resistance and a 75V drain-source breakdown voltage.

Intersil’s HUFA7510S3S is a 75V, 75A MOSFET boasting an on-resistance per unit area of silicon that is among the lowest in the industry. The device is engineered to withstand high energy in the avalanche mode and also features low gate charge, fast recovery time, and a lower reverse body diode charge (QRR) for applications that require fast switching speeds and improved efficiency.

"Automotive electronic control module and system manufacturers are proving 42V power supply designs on the road right now," said Peter Blumenroether, marketing manager for automotive discretes at Intersil. "Even though the first production vehicles equipped with the new power supply systems will not hit the road before the year 2001, Intersil recognizes the enormous growth potential for discrete power products in the developing 42V environment. We are dedicated to this market and want to secure our position as a major supplier right from the start."

To reduce time to market and facilitate design in, Intersil offers simulation models including temperature compensated PSPICE™ and SABER© electrical models.

About UltraFET
Intersil’s advanced UltraFET process technology achieves the lowest possible on-resistance per silicon area, lower gate charge, improved dynamic switching characteristics, and other capabilities resulting in unparalleled device performance. UltraFET devices withstand high peak currents and energy in the avalanche mode, essential when switching inductive loads.

Intersil remains committed to investments in new technology, product development, and software with an emphasis on providing solutions for our customers. All Intersil automotive UltraFET devices are fully compliant with the latest AEC Q101 specification, including the recently added preconditioning with forced moisture penetration, and all of Intersil’s Power Discrete facilities are QS9000 certified.
