Description
The SFH628A (DIP) and SFH6286 (SMD) feature a high current transfer ratio, low coupling capacitance and high isolation voltage. These couplers have a GaAs infrared emitting diode, which is optically coupled to a silicon planar phototransistor detector, and is incorporated in a plastic DIP-4 or SMD package. The coupling devices are designed for signal transmission between two electrically separated circuits. The couplers are end-stackable with 2.54 mm lead spacing.

• High Common-mode Interference Immunity
• Isolation Test Voltage, 5300 VRMS
• Low Coupling Capacitance
• Good CTR Linearity Depending on Forward Current
• Low CTR Degradation
• High Collector-emitter Voltage, VCEO = 55 V
