DESCRIPTION
The SFH620AA, SFH620AGB features a high current transfer ratio, low coupling capacitance and high isolation voltage. These couplers have a GaAs infrared emitting diode emitter, which is optically coupled to a silicon planar phototransistor detector, and is incorporated in a plastic DIP-4 package.

FEATURES
• High current transfer ratios
    - at 5 mA: 50 to 600 %
    - at 1.0 mA: 45 % typical (> 13)
• Low CTR degradation
• Good CTR linearity depending on forward current
• Isolation test voltage, 5300 VRMS
• High collector emitter voltage, VCEO = 70 V
• Low saturation voltage
• Fast switching times
• Temperature stable
• Low coupling capacitance
• End stackable, 0.100" (2.54 mm) spacing
• High common mode interference immunity (unconnected base)
• SMD option, see SFH620A, SFH6206 datasheet
