Overview
The PS2566L-1-F3-A is a photovoltaic output optoisolator manufactured by CEL. It features a Darlington transistor output configuration designed for high isolation voltage applications. The component utilizes surface-mount technology in a 4-SMD package. Key electrical characteristics include an insulation voltage of 5000 Vrms and a typical current transfer ratio of 1500%. It supports a maximum forward current of 80 mA with a forward voltage of 1.4 V. The device operates within a temperature range of -55°C to +100°C and provides a collector-emitter saturation voltage of 300 mV.
Feature Summary
- High isolation voltage capability for safe signal transmission between isolated circuits
- Darlington transistor output structure providing high current gain
- Surface-mount design suitable for automated assembly processes
Applications
- AC input detection systems requiring galvanic isolation
- Industrial control interfaces with high noise immunity needs
- Power supply feedback loops for safety compliance
Procurement Notes
Verify the specific suffix F3-A against the manufacturer's latest documentation to confirm pinout and packaging details. Confirm RoHS compliance status through official datasheets. Check for obsolescence notices as this part may be discontinued or replaced by newer series variants from Renesas Electronics. Ensure the supplier provides original manufacturer traceability.
Selection Notes
Select this component when high isolation voltage and high current transfer ratio are required in a compact surface-mount form factor. Consider the Darlington output's slower switching speed compared to standard phototransistors. Evaluate thermal management requirements given the power dissipation limits. Verify compatibility with existing PCB footprint designs for 4-SMD packages.
Part Context
This part belongs to the PS2566L series of optoisolators, which are designed for AC input applications. The series typically includes variants with different output configurations and packaging options. The PS2566L-1-F3-A specifically denotes the Darlington output version with SMD packaging. Related parts in the family may offer different isolation voltages or output types.
Replacement Considerations
Check for direct replacements such as PS2566L-1-V or similar variants from the same manufacturer family. Verify that substitute components maintain the same 5000 Vrms isolation rating and Darlington output characteristics. Ensure pin compatibility and thermal performance match the original design requirements.
