Overview
The Littelfuse CPC1301G is a single-channel OptoMOS relay featuring a photodarlington output. It provides high-voltage isolation with a 5000 Vrms rating and supports up to 350 V collector-emitter voltage. The device offers a minimum current transfer ratio of 1000% with a maximum forward current of 70 µA. Key electrical parameters include a 1.4 V forward voltage, 1.2 V saturation voltage, 40 µs rise time, and 2.6 µs fall time.
Feature Summary
- Provides optical isolation for switching control circuits using a photodarlington output stage.
- Features a high isolation barrier rating suitable for high-voltage applications.
- Designed for low input current operation to minimize power consumption.
Applications
- High-voltage switching in industrial automation systems
- Test and measurement equipment requiring electrical isolation
- Medical instrumentation safety circuits
Procurement Notes
Verify the component status as the source indicates it may be obsolete or nearing end-of-life. Confirm the manufacturer designation, as sources list both IXYS Integrated Circuits and Littelfuse. Ensure the 4-DIP package matches the design requirements before ordering.
Selection Notes
Select this component when high output voltage capability and low input drive current are required. The photodarlington configuration provides high current transfer ratios compared to standard phototransistors. Verify that the 350 V output rating meets the load requirements and that the DIP package fits the PCB layout constraints.
Part Context
The CPC1301G belongs to the CPC1301 series of single optocouplers from Littelfuse (formerly IXYS). These devices utilize OptoMOS technology to provide reliable switching with no mechanical contacts. The series is designed for applications needing robust electrical isolation between control and load circuits.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the potential obsolescence status, alternative components should be evaluated based on matching voltage ratings, current transfer ratios, and package dimensions.
FAQ
What is the maximum collector-emitter voltage?
The maximum collector-emitter voltage is 350 V.
Does the CPC1301G have a mechanical contact?
No, it uses an optical isolation method with a photodarlington output, eliminating mechanical contacts.
