The Vishay Dale SFH628A-4 is a DIP-4 packaged optocoupler featuring a phototransistor output. It is designed for reliable signal transmission between circuits requiring electrical isolation. Key electrical characteristics include a high Collector-Emitter Voltage of 55 V and an Isolation Test Voltage of 5300 V RMS, ensuring robust performance in demanding applications. The device utilizes a GaAs infrared emitting diode optically coupled to a silicon planar phototransistor. With a lead spacing of 2.54 mm, it is suitable for through-hole mounting. The SFH628A-4 is part of a series offering various Current Transfer Ratios (CTR), with this specific variant providing a CTR range of 160% to 500%.
This optocoupler is well-suited for applications requiring high common-mode interference immunity and good CTR linearity. Its design facilitates signal transmission in systems such as industrial controls, battery-powered equipment, and office machines where electrical isolation is critical. The DIP-4 package allows for standard through-hole assembly processes.
