Overview
The PS2566L-1-V-A is a single-channel optocoupler from the NEPOC series, featuring an AC-input GaAs LED and an NPN silicon Darlington phototransistor. It utilizes a surface-mount Gull-wing package with lead bending designed for long creepage distance. Key electrical parameters include a maximum collector-emitter voltage of 40 V, a typical current transfer ratio (CTR) of 2000%, and a high isolation voltage of 5000 Vrms. The device supports a maximum forward current of 80 mA and operates within a temperature range of -55°C to +100°C.
Feature Summary
- AC input response capability
- High isolation voltage rating
- Surface mount Gull-wing package with extended creepage distance
Applications
- Industrial control systems requiring high isolation
- Power supply feedback circuits
- Signal transmission across isolated boundaries
Procurement Notes
Verify the specific suffix 'V' against the manufacturer's latest documentation to confirm pinout configuration and package dimensions. Ensure compliance with RoHS directives if required by your application, as historical data indicates potential variations in lead composition. Cross-reference the ordering number with official CEL catalogs to distinguish between tape-and-reel and tube packaging options.
Selection Notes
Select this component when high current transfer ratio and AC input compatibility are required. The long creepage distance design makes it suitable for applications demanding robust insulation performance. Verify that the 40 V collector-emitter voltage meets the load requirements and that the surface-mount footprint aligns with the PCB layout constraints.
Part Context
This part belongs to the PS2566L series, which includes variants like PS2566L-2 and PS2566L-4 offering multiple channels. The 'L' designation specifically denotes the lead-bending type for surface mounting, distinguishing it from standard DIP packages. It is part of the NEPOC family known for high-speed switching and high isolation characteristics.
Replacement Considerations
Direct substitutes include other parts within the PS2566L series such as PS2566L-1-E3 or PS2566L-1-F3, provided the package and electrical specifications match. Verify that any replacement maintains the same AC input response and isolation voltage ratings.
