DESCRIPTION
The SFH620A (DIP) and SFH6206 (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 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
• 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
• Low CTR degradation
• Temperature stable
• Low coupling capacitance
• End-stackable, 0.100" (2.54 mm) spacing
• High common-mode interference immunity
• Material categorization: for definitions of compliance
