Vishay's New High-Voltage Optocoupler Meets ATEX Standard for Use in Potentially Explosive Atmospheres

Device Offers Input-to-Output Distance of >3 mm, CTR of 50% to 300%

MALVERN, PENNSYLVANIA - September 17, 2003 - Vishay Intertechnology, Inc. (NYSE: VSH) today announced the release of a new high-voltage optocoupler that meets the European Union's ATEX standard for operation in potentially explosive atmospheres.

Designed to enable galvanically separated circuits in environments including coal mines, chemistry labs, refineries, and mills,the new Vishay Semiconductors CNY65Exi consists of a phototransistor optically coupled to a gallium arsenide (GaAs) infrared-emitting diode in a four-lead, plastic package.

The CNY65Exi's optical components are mounted opposite one another, maintaining the highest safety standards with an input-to-output distance of >3 mm. The device's specially molded plastic package measures 17.8 mm by 9.6 mm with a height of 6.1 mm. It features a pin index of 15.24 mm and is designed for a J coupling system.

The new optocoupler features a current transfer ratio (CTR) range of 50% to 300%. The creepage current resistance of the isolation material according to VDE 0303/DIN 53480 is > or = 475, and the isolation test voltage is 11.6 kV. A very low typical coupling capacity of 0.3 pF provides resistance to high-noise voltage.

In addition to meeting EU health and safety guidelines EN 50014:1997+A1+A2 and EN 50020:1994, the CNY65Exi is ATEX-certified (PTB 03 ATEX 2033 U) for explosive atmospheres according to the European guideline 94/9/EG and meets specifications for isolation material according to UL94-VO-flammability class. The device also meets test class 25/100/21 DIN 40045 requirements.

Samples and production quantities of the new CNY65Exi high-voltage optocoupler from Vishay Semiconductors are available now, with lead times of six weeks for larger orders. Pricing for U.S. delivery in 100,000-piece quantities starts at $1.50 per piece.

Vishay, a Fortune 1,000 Company listed on the NYSE, is one of the world's largest manufacturers of discrete semiconductors (diodes, rectifiers, transistors, optoelectronics, and selected ICs) and passive electronic components (resistors, capacitors, inductors, and transducers). The Company's components can be found in products manufactured in a very broad range of industries worldwide. Vishay is headquartered in Malvern, Pennsylvania, and has plants in sixteen countries employing over 25,000 people. Vishay can be found on the Internet at www.vishay.com.
