Optocoupler, Phototransistor Output, Low Input Current
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 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 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
• 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
• Compliant to RoHS Directive 2002/95/EC and in
accordance to WEEE 2002/96/EC

Notes
• Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not
implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute
maximum ratings for extended periods of the time can adversely affect reliability.
(1) Refer to reflow profile for soldering conditions for surface mounted devices (SMD). Refer to wave profile for soldering conditions for through
hole devices (DIP).
