Optocoupler, Phototransistor Output, High Reliability, 5300 VRMS
DESCRIPTION
The SFH615A 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 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 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 VRMS or DC. Specifications subject to
change.

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). Refer to wave profile for soldering conditions for through
hole devices (DIP).
Note
• Minimum and maximum values are testing requirements. Typical values are characteristics of the device and are the result of engineering
evaluation. Typical values are for information only and are not part of the testing requirements.
