The 110 °C rated SFH617A (DIP) feature a high current transfer ratio, 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. The couplers are end-stackable with 2.54 mm spacing. Creepage and clearance distances of >, 8.0 mm are achieved with option 6.Operating temperature from -55 °C to +110 °CGood CTR linearity depending on forward currentIsolation test voltage, 5300 VRMSAPPLICATIONS:AC adapterSMPSPLC
