Optocoupler, Photodarlington Output,
High Gain (Quad Channel)
ILQ32
Vishay Semiconductors
DESCRIPTION
The ILQ32 is optically coupled isolators with a gallium
arsenide infrared LED and a silicon photodarlington sensor.
Switching can be achieved while maintaining a high degree
of isolation between driving and load circuits.
These optocouplers can be used to replace reed and
mercury relays with advantages of long life, high speed
switching and elimination of magnetic fields.
FEATURES
• Isolation test voltage, 5300 VRMS
• High isolation resistance, 1011 typical
• Low coupling capacitance
• Standard plastic DIP package
• Compliant to RoHS Directive 2002/95/EC and
in accordance to WEEE 2002/96/EC
AGENCY APPROVALS
• UL1577, file no. E52744 system code H, double protection
• cUL tested to CSA 22.2 bulletin 5A
• DIN EN 60747-5-2 (VDE 0884)/DIN EN 60747-5-5
(pending), available with option 1
• BSI IEC 60950; IEC 60065
Notes
• Additional options may be possible, please contact sales office.

Note
• Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not
implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute
maximum ratings for extended periods of the time can adversely affect reliability.
Note
• Minimum and maximum values are testing requirements. Typical values are characteristics of the device and are the result of engineering
evaluation. Typical values are for information only and are not part of the testing requirements.
