Vishay Siliconix has announced the introduction of seven new temperature- and current-sensing TrenchFETs - including the industry's first 75V current-sensing MOSFET - in a thermally-enhanced D2PAK package.

The 30V to 75V devices 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.

The proprietary D2PAK packages are claimed by the company to 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 milliohm.

The higher current-handling capability and lower on-resistance values allow designers to save board space and lower production costs because in some cases fewer MOSFETs need to be run in parallel to reach the required current level and power load for a given application.

Vishay is an exhibitor at the IIC-China Fall 2002 and the 5th Annual Communications Design China & Exhibition to be held from September 19 to 20 in Guangzhou and from September 23 to 24 in Chengdu. Both eeEvents are organized by eMedia Asia Ltd, a Global Sources and CMP Media joint venture.
