Optocoupler, Phototransistor Output, High Reliability, 5300 VRMS
DESCRIPTION
The SFH6156 features a variety of transfer ratios, low
coupling capacitance and high isolation voltage. This
coupler has a GaAs infrared diode emitter, which is optically
coupled to a silicon planar phototransistor detector, and is
incorporated in a plastic SMD package.
The coupling devices are designed for signal transmission
between two electrically separated circuits.
FEATURES
• Excellent CTR linearity depending on forward
current
• Isolation test voltage, 5300 VRMS
• Fast switching times
• Low CTR degradation
• Low coupling capacitance
• Material categorization: For definitions of compliance
please see www.vishay.com/doc?99912

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).

• 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.
