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 cou-

pled to a silicon planar phototransistor detector, and

is incorporated in a plastic DIP-4 or SMD package.

The coupling devices are designed for signal trans-

mission 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

Order Information

For additional information on the available options refer to

Option Information.

Absolute Maximum Ratings

Stresses in excess of the absolute Maximum Ratings can cause permanent damage to the devise. 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 Rating for extended periods of the time can adversely affect reliability.
