Optocoupler, Phototransistor Output, AC Input, Low Input Current,
SSOP-4, Half Pitch, Mini-Flat Package
DESCRIPTION
The VOS628A series has a GaAs infrared emitting diode
emitter, which is optically coupled to a silicon planar
phototransistor detector, and is incorporated in a 4-pin
50 mil lead pitch mini-flat package.
It features a high current transfer ratio at low input current,
low coupling capacitance, and high isolation voltage.
The coupling devices are designed for signal transmission
between two electrically separated circuits.
FEATURES
• High CTR with low input current
• Low profile package (half pitch)
• High collector emitter voltage, VCEO = 80 V
• Isolation test voltage, 3750 VRMS
• Low coupling capacitance
• High common mode transient immunity
• Compliant to RoHS Directive 2002/95/EC and
in accordance to WEEE 2002/96/EC

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.
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.
