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.
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
Material categorization: for definitions of compliance
