Overview
The CEL PS2501-1 is a single-channel transistor output optocoupler featuring a GaAs light emitting diode and an NPN silicon phototransistor. It provides high isolation voltage of 5000Vrms and supports a current transfer ratio of 300%. The device operates with a collector to emitter voltage of 80V and exhibits typical rise time of 3 µs. Packaged in DIP-4, it serves as an optically coupled isolator for signal transmission across isolated circuits.
Feature Summary
- Contains a GaAs LED and NPN silicon phototransistor for optical coupling
- Provides high isolation voltage capability
- Features high-speed switching performance
Applications
- Signal transmission between isolated circuits
- Microprocessor input/output interface
- Solid-state relay driver applications
Procurement Notes
Verify the manufacturer designation, as this component was originally developed by NEC and is now produced by CEL under Renesas ownership. Confirm the specific suffix indicates standard packaging or automotive qualification if required. Ensure the datasheet matches the exact part number variant to avoid discrepancies in electrical characteristics or pin configuration.
Selection Notes
Select this component when high isolation voltage and reliable transistor output are required for single-channel applications. Consider the 5000Vrms isolation rating for safety-critical interfaces. Evaluate the 300% CTR and 80V VCEO against load requirements. Verify compatibility with control logic levels and switching speed needs compared to alternative optocouplers.
Part Context
This part belongs to the PS2501 series of high isolation voltage photo couplers. The series includes variants like PS2501-4 for quad configurations. Originally manufactured by NEC, production continues under CEL. The series is designed for general-purpose isolation in industrial and consumer electronics.
Replacement Considerations
Direct substitutes include other single-channel transistor output optocouplers with similar 5000Vrms isolation and DIP-4 packaging. Verify pinout compatibility and electrical parameters such as CTR and propagation delay before substitution.
