SFH628A-4

SFH628A 系列 单通道 55 V 5300 Vrms 光电晶体管 光耦合器 - DIP-4

The is a 1-channel 4-pin Phototransistor Output Optocoupler with AC input. It features a high current transfer ratio, low coupling capacitance and high isolation voltage. This coupler has a GaAs infrared emitting diode, 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. Creepage and clearance distances of >8mm. This version complies with IEC 60950 DIN VDE 0805 for reinforced insulation to an operation voltage of 400VRMS or DC. It is suitable for battery-powered equipment and office machines.
