SFH6286-4

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 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. Creepage and clearance distances of <gt/> 8 mm are achieved with option 6. This version complies with IEC 60950 (DIN VDE 0805) for reinforced insulation to an operation voltage of 400 VRMS or DC.

• Phototransistor output, AC input, low input current optocoupler
• 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
