Overview
The PS2581L2-F3-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output housed in a 4-pin DIP Gull Wing package. Key electrical specifications include a maximum collector-emitter voltage of 80 V, a maximum collector current of 50 mA, and a forward voltage of 1.17 V at a maximum forward current of 10 mA. The device provides 5000 Vrms isolation voltage with a typical rise time of 3 µs and fall time of 5 µs. It operates within a temperature range of -55°C to 100°C and complies with RoHS standards.
Feature Summary
- Provides high-voltage isolation between input and output circuits using optical transmission.
- Utilizes an NPN phototransistor output for reliable switching applications.
- Designed for surface mount installation in a compact 4-pin DIP Gull Wing form factor.
Applications
- Signal isolation in industrial control systems
- Interface circuits for microprocessors and logic devices
- Power supply feedback loops
Procurement Notes
Verify the specific suffix F3-A against the official Renesas datasheet to confirm package type and tape/reel specifications. Confirm component status as Not Recommended for New Designs (NRND) prior to procurement to ensure long-term availability and support alignment with project lifecycle requirements.
Selection Notes
Select this component when a single-channel isolation interface with moderate speed and high voltage capability is required. Ensure the application circuit supports the 10 mA forward current limit and 50 mA collector current rating. Verify that the 4-pin SMD footprint matches the PCB layout constraints and thermal management needs.
Part Context
This part belongs to the PS2581 series of transistor output optocouplers from Renesas Electronics. The series is designed for general-purpose signal isolation, offering a balance of performance and reliability. The L2 variant specifically denotes the package configuration and electrical characteristics defined in the product specification.
Replacement Considerations
Consult the official Renesas cross-reference documentation for verified substitute part numbers. Do not assume functional equivalence with other brands or series without validating pinout, electrical ratings, and isolation voltage specifications against the original datasheet.
