Siliconix Intros Seven New SUM Series MOSFETs

September 20, 2002 by Jeff Shepard

Siliconix Inc. (Santa Clara, CA) announced seven new temperature- and current-sensing TrenchFETs®, including what the company claims is the industry's first 75V current-sensing MOSFET, 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 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. 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 4.5mW.

Samples and production quantities of the SUM50N03-13LC, SUM60N04-12LT, SUM60N04-05LT, SUM60N04-06T, SUM60P05-11LT, SUM60N08-07C and SUM60N08-07T are available now, with lead times of 10 to 12 weeks for larger orders.
