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.
Creepage and clearance distances of > 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.

FEATURES
• 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
• Material categorization: For definitions of compliance
