Siliconix Presents New SUM Series TrenchFETs

August 18, 2002 by Jeff Shepard

Siliconix Inc. (Santa Clara, CA), a subsidiary of Vishay Intertechnology Inc. (Malvern, PA), announced seven new temperature- and current-sensing TrenchFETs in a thermally enhanced D2PAK package. The new 30V to 75V TrenchFETs are designed for any application requiring temperature or current sensing, such as motor drives and valve drives, as well as industrial and automotive applications, including door modules, EPS, and 12V or 42V powernet systems in cars.

The temperature-sensing function of the new SUM Series devices can be used to allow the MOSFET to shut down its circuitry before extreme temperature causes circuit malfunction or damage. Likewise, the current-sensing diode allows the MOSFET to shut down circuitry when it detects excessive current, as in the case of a stalled motor or short circuit.

The new power MOSFETs are provided in an enhanced D2PAK with a proprietary lead-frame design that allows the devices to offer low thermal resistance, depending on the die size used. With no increase in footprint, the new TrenchFETs provide thermal resistance up to 33 percent lower than standard D2PAK packages, as well as up to 20 percent higher current-handling capability, up to 50 percent higher power dissipation, and maximum on-resistance ratings as low as 4.5 milliohms.

Samples and production quantities of the SUM50N03-13LC, SUM60N04-12LT, SUM60N04-05LT, SUM60N04-06T, SUM60P05-11LT, SUM60N08-07C and SUM60N08-07T are now available, with lead times of 10 to 12 weeks for larger orders. Pricing for US delivery in 100,000-piece quantities ranges from $0.72 to $2.14.
