Optocoupler, Phototransistor Output, AC Input, Low Input Current
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
please see www.vishay.com/doc?99912
APPLICATIONS
• Telecom
• Industrial controls
• Battery powered equipment
• Office machines
AGENCY APPROVALS
• UL1577, file no. E52744 system code H
• DIN EN 60747-5-5 (VDE0884-5), available with option 1

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).
Note
• Minimum and maximum values are testing requirements. Typical values are characteristics of the device and are the result of engineering
evaluation. Typical values are for information only and are not part of the testing requirements.
