Optocoupler, Phototransistor Output,
with Base Connection in SOIC-8 Package
IL205AT/206AT/207AT/208AT
Vishay Semiconductors
DESCRIPTION
The IL205AT/IL206AT/IL207AT/IL208AT are optically
coupled pairs with a gallium arsenide infrared LED and a
silicon NPN phototransistor. Signal information, including a
DC level, can be transmitted by the device while maintaining
a high degree of electrical isolation between input and
output. This family comes in a standard SOIC-8A small
outline package for surface mounting which makes them
ideally suited for high density application with limited space.
In addition to eliminating through-hole requirements, this
package conforms to standards for surface mounted
devices.
A specified minimum and maximum CTR allows a narrow
tolerance in the electrical design of the adjacent circuits. The
high BV
CEO
of 70 V gives a higher safety margin compared
to the industry standard 30 V.
