Overview
The CPC1302GSTR is a dual-channel optocoupler featuring independent unidirectional inputs and high-voltage Darlington outputs. It provides 3750Vrms input/output isolation and supports a 350V breakdown voltage. The device operates with a maximum forward current of 1mA and ensures a minimum current transfer ratio of 1000%. Packaged in an 8-pin surface mount DIP, this component is designed for robust signal transmission across isolated circuits.
Feature Summary
- Dual-channel architecture with identical, independent circuit paths
- High-voltage Darlington output configuration for enhanced switching capability
- Surface mount tape and reel packaging for automated assembly
Applications
- Telecom switching systems
- Industrial control interfaces
- Signal isolation in measurement equipment
Procurement Notes
Verify the specific suffix GSTR to confirm surface mount tape and reel packaging availability. Ensure compatibility with standard 8-pin DIP footprints during PCB layout. Cross-reference Littelfuse product change notices for any recent manufacturing updates or material substitutions that may affect long-term supply chain stability.
Selection Notes
Select this component when high isolation voltage and fast switching are required in compact designs. The Darlington output structure offers higher gain compared to standard phototransistor outputs. Consider the 1mA forward current limit when designing drive circuits to ensure optimal performance without exceeding specifications.
Part Context
This part belongs to the CPC1302 series of dual optocouplers manufactured by Littelfuse. It shares architectural similarities with other devices in the family but is distinguished by its specific surface mount packaging and electrical ratings tailored for modern electronic applications requiring reliable galvanic isolation.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical parameters before considering alternative components from other manufacturers.
