Optocoupler, Phototransistor Output, AC Input, Low Input Current,
4 Pin LSOP, Long Creepage Mini-Flat Package
DESCRIPTION
The VOL628A has two GaAs infrared emitting diodes, which
are optically coupled to a silicon planar phototransistor
detector, and are incorporated in a 4 pin LSOP wide body
package.
It features a high current transfer ratio, low coupling
capacitance, and high isolation voltage.
The coupling device is designed for signal transmission
between two electrically separated circuits.
FEATURES
• Low profile package
• High collector emitter voltage, VCEO = 80 V
• Isolation test voltage, 5000 VRMS
• Low coupling capacitance
• High common mode transient immunity
• Material categorization:
for definitions of compliance please see

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
