MALVERN, PENNSYLVANIA-May 4, 2001-Two new series of SMD optocouplers that provide reinforced isolation in a 2-mm high package - one of the industry's thinnest for this device type - have been announced by Vishay Intertechnology, Inc. (NYSE: VSH).

The new Vishay Telefunken devices consist of a phototransistor optically coupled to a gallium arsenide infrared-emitting diode. The devices offer designers two Miniflat package options: the standard 4-pin (TCLT10xx) or a new, industry-first, 5-pin base-connected version (TCLT11xx).

Intended for current isolation, the new Miniflat SMD optocouplers are optimized for miniaturized products such as PC cards (PCMCIA), set-top boxes, fax machines, modems, digital TV, switchmode power supplies, line receivers, computer peripheral interfaces, microprocessor system interfaces and other systems requiring a high level of package integration. All devices in both series conform to the VDE0884, IEC950/EN60950, VDE0804, and IEC65 standards for electrical safety.

Built on Vishay Telefunken co-planar technology, the four-lead TCLT10xx Series and five-lead TCLT11xx Series optocouplers ensure maximum safety and reliability by providing a stable distance between the emitter and detector chips. Creepage distance for both series is >8 mm. Providing an insulation voltage of 5,000 Vrms, the surface-mountable devices also feature a transistor output and a forward current of 60 mA.

Vishay offers nine different CTR options in both the TCLT10xx and TCLT11xx families, with values ranging from 40% to 600%. Additional series features include a -40C to +100C operating ambient temperature range, a low typical coupling capacitance of just 0.3 pF, and a low temperature coefficient of current transfer ratio (CTR).

All nine of the TCLT10xx and TCLT11xx Series devices are supplied in reel and tape packaging for high-speed assembly, with 3,000 pieces per reel. Samples and production quantities are available now, with lead times of six 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).
