SFH6186 datasheet


Description :

The SFH618A (DIP) and SFH6186 (SMD) 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 silicon planar phototransistor detector, and isincorporated in a plastic DIP-4 or SMD package.


• Good CTR linearity depending on forward current
• Low CTR degradation
• High collector emitter voltage, VCEO = 55 V
• Isolation test voltage, 5300 VRMS
• Low coupling capacitance
• End stackable, 0.100″ (2.54 mm) spacing
• High common mode transient immunity


• Telecom
• Industrial controls
• Battery powered equipment
• Office machines
