(October 25, 2010) — Vishay Intertechnology Inc. (NYSE: VSH) released two devices in its first family of power MOSFETs built on an enhanced process flow with strict manufacturing process controls for implantable medical applications.

The devices released today are an n- and p-channel 12 V MOSFET in the PowerPAK SC-70 (SMMA511DJ) and a 20 V dual n-channel MOSFET in the PowerPAK SC75 (SMMB912DK). The new MOSFETs are distinguished from commercial devices by their high quality and reliability as ensured by enhanced quality control gates for every lot: statistical bin limit (SBL), yield limit (SYL), and part average testing (PAT) controls for wafers and component packages, and homogeneous reliability testing for all wafer lots. The rigorous SMM medical MOSFET process flow also includes an acceptable quality level (AQL) of 0.04%.

Applications for the new MOSFETs will include load switching in drug delivery systems, defibrillators, pacemakers, hearing aids, and other implantable devices. Their very small package dimensions (2 mm by 2 mm for the SMMA511DJ, 1.6 mm by 1.6 mm for the SMMB912DK) will help save space in miniaturized medical devices, while their ultra-low on-resistance, down to 0.040 Ω, will lower conduction losses and thus maximize battery life.

The Vishay Siliconix SMM medical MOSFET family includes n-channel, p-channel, and n- and p-channel pair configurations in various package sizes. Complete details are available at http://www.vishay.com/medical-mosfets/.

Samples of the SMMA511DJ and SMMB912DK are available now. Production quantities will be available in Q4 2010 with lead times of 16 weeks for large orders.

Vishay Intertechnology Inc. (NYSE: VSH), manufactures discrete semiconductors (diodes, MOSFETs, and infrared optoelectronics) and passive electronic components (resistors, inductors, and capacitors).
