Overview
The CPC1303G is a single-channel optocoupler featuring a photovoltaic output configuration. It provides high-voltage isolation with a minimum breakdown voltage (BVCEO) of 30V and a typical current transfer ratio of 1000%. The device supports an input control current of 0.2mA and exhibits a maximum saturation voltage of 0.5V. It offers 5kV isolation capability in a compact package, suitable for precise signal switching applications requiring galvanic separation.
Feature Summary
- Provides optical isolation between input control circuits and output loads
- Features a photovoltaic transistor output for low-power switching
- Designed for high-voltage isolation requirements
Applications
- High-voltage isolation and switching
- Control circuit isolation
- Signal transmission in isolated systems
Procurement Notes
Verify the specific suffix 'G' to confirm the DIP-4 package variant, as other suffixes like 'R' indicate tape-and-reel packaging. Confirm the manufacturer source, noting that Littelfuse acquired IXYS Integrated Circuits; ensure the datasheet aligns with the current Littelfuse specifications rather than legacy IXYS documents to avoid discrepancies in mechanical or electrical ratings.
Selection Notes
Select this component when a single-channel, high-isolation optocoupler with photovoltaic output is required. The 30V breakdown voltage and 5kV isolation rating make it suitable for applications demanding robust galvanic separation. Ensure the input forward current requirements match the system's drive capabilities, as the device operates with low input currents.
Part Context
The CPC1303G belongs to the Single Optocouplers series from Littelfuse. This series utilizes OptoMOS technology to provide reliable switching solutions. The part is distinct from dual-channel variants like the CPC1302, offering a single independent channel for cost-effective isolation in space-constrained designs.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing footprints and electrical parameters before considering alternative sources.
