Vishay Intertechnology, Inc. 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 what the company says is 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 5mA and at 1mA for the VO618A. Option 6 offers a creepage distance of ≥8mm.
