February 23, 2010 – Providing power electronics design engineers with a high voltage device capable of high speed digital data transmission, OPTEK Technology developed an optical isolator that delivers AC and DC voltage isolation up to 16KV while achieving digital data transmission rates of 2Mbd. Designated OPI1268, the UL-recognized high voltage optoisolator is designed for power isolation in high voltage PC board circuits in industrial electronics systems, medical electronic equipment and office machines. The OPI1268 optoisolator combines a high efficiency GaAlAs (Gallium Aluminum Arsenide) LED with a peak wavelength of 850nm, optically coupled to a Photologic photodiode in the output IC. Forward current (IF) is 10mA typical/50mA max, with typical propagation delays (tPHL-tPLH) ≤ 500ns.
Creepage distance/air path is 0.970 inches (24.64mm), and the devices are UL recognized under file #E58730.Packaged in an opaque high dielectric plastic housing, the OPI1268 device measures 27.94mm x 6.35mm x 8.89mm with a five-lead configuration (cathode, anode, Vcc, output and ground).
Operating temperature range is from -40°C to +100°C.Typical pricing for the OPI1268 optoisolator is $3.48 in quantities of 1,000 pieces.
