The SFH620A-2 is an AC Input Phototransistor Output Optocoupler features a high current transfer ratio, low coupling capacitance and high isolation voltage. This coupler has a GaAs infrared diode emitter, which is optically coupled to a silicon planar phototransistor detector. The coupling device is designed for signal transmission between two electrically separated circuits. The coupler is end-stackable with 2.54mm lead spacing. This version complies with IEC 60950 (DIN VDE 0805) for reinforced insulation to an operation voltage of 400Vrms or DC.
