Optocoupler, Phototransistor Output, with Base Connection in

SOIC-8 Package, 110 °C Rated

IL1205AT/1206AT/1207AT/1208AT

Vishay Semiconductors

DESCRIPTION

The 110 °C IL1205AT/1206AT/1207AT/1208AT 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-8 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

to the industry standard 30 V.
