HEILBRONN, GERMANY - July 28, 1999 - A new family of 20 Schottky glass diodes, including the first devices in the exclusive, assembly-friendly MicroMELF package, was released today by Vishay Intertechnology, Inc. The new Vishay Telefunken products span a range of maximum voltage, forward voltage, and package options, significantly adding to the options available to designers of computers, cell phones, data storage systems, and many other applications.

The new devices combine a choice of 30-, 40-, 50-, and 60-V maximum reverse voltages with four packages options: the DO-35, the SOD80 MiniMELF, the SOD80 QuadroMELF, and the exclusive Vishay Telefunken MicroMELF. With their low typical forward voltages, ranging from 320 mV for the 30-V devices to 410 mV for the 40- and 60-V devices, the new glass diodes will minimize forward losses in cell phones, notebook computers, and other mobile applications where efficient power consumption is a must.

In addition to lower conduction losses, the devices feature fast switching speeds for more efficient operation, with typical turn-on times as low as 3 ns.

The square cross-section of Vishay Telefunken's QuadroMELF and MicroMELF packages dramatically speeds up assembly of printed circuit boards. When assembled using vacuum techniques, the pick-and-place procedure is 20% to 40% faster than with standard, round diodes. In addition to streamlining the assembly process, Vishay's MicroMELF is the smallest glass package on the market. With dimensions as small as 2 mm x 1.25 mm x 1.25 mm and using the industry-standard 0805 outline, MicroMELF Schottky diodes help reduce space requirements while using the same solder pads and design rules for placing and soldering traditional devices.

"Whether they're used as a signal rectifier in an RF circuit, a low-voltage power supply, or any other of their many target applications, these new Schottky diodes will save space, accelerate the assembly process, and provide the reliable performance for which designers have relied on Vishay's Telefunken products for more than 30 years," said Juergen Wilhelm, Senior Manager, Marketing, Diodes.

Samples and production quantities of all 20 new devices are available now, with lead times of 8 to 10 weeks for larger orders.

Vishay Intertechnology, Inc., a Fortune 1000 Company listed on the NYSE (VSH), is one of the world's largest manufacturers of discrete semiconductors (diodes, MOSFETs, and infrared optoelectronics) and passive electronic components (resistors, inductors, and capacitors). These components are used in virtually all types of electronic devices and equipment, in the industrial, computing, automotive, consumer, telecommunications, military, aerospace, power supplies, and medical markets.
