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 > 8.0 mm are achieved
with option 6. This version complies with IEC 60950
(DIN VDE 0805) for reinforced insulation to an operation
voltage of 400 V
RMS
or DC.
APPLICATIONS
• Telecom
• Industrial controls
• Battery powered equipment
• Office machines
AGENCY APPROVALS
• UL1577, file no. E52744 system code J
• DIN EN 60747-5-5 (VDE 0884) available with option 1
• BSI IEC 60950; IEC 60065

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.
