Overview
The CPC1302G is a dual optocoupler manufactured by Littelfuse/IXYS, housed in an 8-pin DIP package. It features two identical, independent channels, each with a unidirectional input and a high-voltage Darlington output. The device supports a load voltage of 350V and offers a current transfer ratio (CTR) of 1000%. It operates within a temperature range of -40°C to +85°C.
Feature Summary
- Dual channel configuration with independent operation
- High-voltage Darlington output structure
- Unidirectional input control
Applications
- Control circuit switching
- Industrial automation systems
- Metering applications
Procurement Notes
Verify the specific suffix 'G' against the manufacturer's latest documentation to confirm compliance with RoHS directives or other regulatory standards. Ensure the ordering part number matches the exact package type and pinout requirements for your PCB design. Cross-reference with Littelfuse product change notices to confirm manufacturing status and availability.
Selection Notes
Select this component when high-voltage isolation is required between control and load circuits. The dual-channel design allows for cost-effective implementation of multiple isolated switches in a single package. Consider the 350V load voltage rating and the specific CTR requirements for your application logic levels before finalizing the design.
Part Context
This component belongs to the CPC1302 series of Dual Optocouplers from Littelfuse/IXYS. The series provides optically isolated means of switching control circuits using phototransistor outputs. The CPC1302G variant specifically denotes the dual-channel version with high-voltage capabilities, distinct from single-channel counterparts in the same family.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing designs by comparing pinouts, electrical ratings, and package dimensions with alternative dual optocouplers from Littelfuse or other manufacturers.
