Product Description
Product Overview
The VOL618A is a low input current optocoupler featuring a GaAs infrared emitting diode coupled to a silicon planar phototransistor. Housed in a 4-pin LSOP wide body package with long creepage, it offers high current transfer ratio, low coupling capacitance, and high isolation voltage, making it suitable for signal transmission between electrically separated circuits. Its low profile and robust isolation make it ideal for various applications including telecom, industrial controls, battery-powered equipment, office machines, and programmable controllers.
