• Low input current capability: 5 mA
DESCRIPTION
• Compliant to RoHS Directive to 2002/95/EC and in
accordance WEEE 2002/96/EC
The SFH675xT-series, is a dual channel 10 MBd
optocoupler utilizing a high efficient input LED coupled with
an integrated optical photodiode IC detector. The detector
has an open drain NMOS-transister output, providing less
leakage compared to an open collector Schottky clamped
transister output. The internal shield provides a guaranteed
common mode transient immunity of 5 kV/μs for the
SFH6756T and 15 kV/μs for the SFH6757T. The use of a
0.1 μF bypass capacitor connected between pin 5 and 8 is
recommended.
APPLICATIONS
• Microprocessor system interface
• PLC, ATE input/output isolation
• Computer peripheral interface
• Digital fieldbus isolation: CC-link, DeviceNet, profibus,
SDS
• High speed A/D and D/A conversion
AGENCY APPROVALS
• AC plasma display panel level shifting
• UL1577, file no. E52744 system code Y
• Multiplexed data transmission
• cUL - file no. E52744, equivalent to CSA bulletin 5A
• Digital control power supply
• DIN EN 60747-5-5 (VDE 0884) available with option 1
• Ground loop elimination

Note
• The thermal model is represented in the thermal network below. Each resistance value given in this model can be used to calculate the
temperatures at each node for a given operating condition. The thermal resistance from board to ambient will be dependent on the type of
PCB, layout and thickness of copper traces. For a detailed explanation of the thermal model, please reference Vishay’s Thermal
Characteristics of Optocouplers application note.

ESD CAUTION
This is an ESD (electro static discharge) sensitive device. Electrostatic charges accumulate on the human body and test
equipment and can discharge without detection. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality. ESD withstand voltage of this device is up to 1500 V acc. to JESD22-A114-B.
