Optocoupler, Phototransistor Output, AC Input,
SSOP-4, Half Pitch, Mini-Flat Package
DESCRIPTION
The VOS627A 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
• Material categorization:
For definitions of compliance please see
