DESCRIPTION
• Component in accordance to RoHS 2002/95/EC and
WEEE 2002/96/EC
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.
APPLICATIONS
• AC adapters
• PLCs
• Switch mode power supplies
• DC/DC converters
• Microprocessor I/O interfaces
• General impedance matching circuits
A specified minimum and maximum CTR allows a narrow
tolerance in the electrical design of the adjacent circuits. The
high BVCEO of 70 V gives a higher safety margin compared
to the industry standard 30 V.
AGENCY APPROVALS
• UL1577 - file no. E52744 system code Y
• CUL - file no. E52744, equivalent to CSA bulletin 5A
• DIN EN 60747-5-5 available with option 1
