Fotoaccoppiatore Vishay, Montaggio superficiale, uscita Fototransistor, 4 Pin

The Vishay optocoupler feature a variety of transfer ratios, low coupling capacitance and high isolation voltage. These couplers have a GaAs infrared diode emitter, which is optically coupled to a silicon planar phototransistor detector and is incorporated in a plastic DIP-4 package. The coupling devices are designed for signal transmission between two electrically separated circuits.

Excellent CTR linearity depending on forward current
Fast switching times
Low CTR degradation
Low coupling capacitance
