DESCRIPTION
The SFH615A (DIP) and SFH6156 (SMD) feature a variety
of transfer ratios, low coupling capacitance and high isolation
voltage. These couplers have a GaAs infrared diode emitter,
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 up to an operation
voltage of 400 V
RMS
or DC. Specifications subject to change.
APPLICATIONS
• Switchmode power supply
• Telecom
• Battery powered equipment
AGENCY APPROVALS
• UL1577, file no. E52744 system code H or J, double
protection
• DIN EN 60747-5-5 (VDE 0884) available with option 1

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.

Notes

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.
