DESCRIPTION
The 110 °C rated ILD1205T/1206T/1207T 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. The ILD1205T/1206T/
1207T come in a standard SOIC-8 small outline
package for surface mounting which makes it ideally
suited for high density applications with limited space.
In addition to eliminating through-holes 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 of 30 V.
