Original Press Release:

Vishay Intertechnology Releases Six New Low-Input Current Optocouplers with Phototransistor Output in Eco-Friendly Green DIP and Mini-Flat Packages for AC Adapter, Switch Mode Power Supplies, and Programmable Logic Controller Applications

Devices Feature Low-Input Drive Currents of 1 mA and 5 mA, and High CTR Range

MALVERN, Pa. - Vishay Intertechnology, Inc. (VSH: NYSE) is broadening its optoelectronics portfolio with the release of six low-input current optocouplers with phototransistor output in the DIP-4, SSOP-4 half-pitch miniflat, and SOP-4L long miniflat packages. The new optocouplers provide exceptional isolation for human and equipment safety.

The VO617A and VO618A devices, available in the DIP-4 package, offer excellent high-temperature performance and an isolation voltage of 5000 VRMS for switch mode power supply applications. A current transfer ratio (CTR) of 40 % to 320 % is achieved for the VO617A at input drive current of 5 mA and at 1 mA for the VO618A. Option 6 offers a creepage distance of 8 mm.

The VOL617A and VOL618A optocouplers are offered in a low-profile (2 mm) SOP-4L package with 8 mm creepage distance and an isolation voltage of 5000 VRMS. Optimized for AC adapter applications, the VOL617A and VOL618A have a CTR range of 40 % to 320 % at an input drive current of 5 mA and 1 mA respectively.

The VOS618A and VOS628A, in the small SSOP-4 package with an isolation voltage of 3750 VRMS, are suited for programmable logic controller and industrial automation applications. These devices have a CTR range of 63 % to 320 % at a low input drive current of 1 mA. The lower input currents reduce the amount of heat generated and complement the industry's move to lower-power products.

The V0617A, VO618A, VOL617A, and VOL618A optocouplers are manufactured using an eco-friendly "green" molding compound.

Samples and production quantities of the new optocouplers are available now, with lead times of six to eight weeks for large orders. Pricing for U.S. delivery in 10,000-piece quantities is $0.072 for the VO617A and VO618A, $0.18 for the VOS618A, $0.20 for the VOS628A, and $0.28 for the VOL617A and VOL618A.
