Overview
The PS2561L-1-F3-H-A is a single-channel transistor output optocoupler manufactured by CEL, now part of Renesas Electronics. It features an NPN phototransistor output and provides 5000 Vrms isolation voltage. The device operates with a maximum forward current of 80 mA and supports a collector-emitter voltage of 80 V. Key electrical parameters include a minimum current transfer ratio of 80% at 5 mA, a rise time of 3 µs, and a fall time of 5 µs. It is housed in a 4-SMD (DIP-4 Gull Wing) package suitable for surface mount applications.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Utilizes an NPN phototransistor for reliable signal transmission
- Designed for surface mount integration via gull-wing packaging
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal transmission across isolated barriers
Procurement Notes
Verify the specific suffix H-A against official Renesas or CEL documentation to confirm lead bending and taping specifications. Confirm availability status as distribution channels may list discontinued or NRND items. Ensure the component matches the required 4-SMD gull wing form factor for PCB layout compatibility before finalizing orders.
Selection Notes
Select this component when a single channel with 5000 Vrms isolation is required for surface mount designs. The 80 mA forward current capability allows for robust drive conditions. Verify that the 3 µs rise time meets the system's speed requirements. Ensure the NPN output configuration aligns with the receiving circuit's logic levels.
Part Context
This part belongs to the PS2561 series of transistor output optocouplers. The manufacturer CEL was acquired by Renesas Electronics, which continues to support these components. The series is designed for general-purpose isolation applications where compact surface mount packaging and high isolation voltage are critical design constraints.
Replacement Considerations
Check for PS2561L-1-E3 or PS2561L-1-E4 variants from the same family. Verify if PS2561AL1-1-V-A serves as a functional substitute if lead bend specifications differ. Confirm pinout compatibility before substituting.
