Overview
The PS2506L-1-A is a transistor output optocoupler from the CEL NEPOC series, featuring a GaAs LED and NPN silicon Darlington phototransistor in a surface-mount Gull-wing package. It provides high isolation voltage of 5000 Vrms and supports AC input response. Key electrical parameters include a typical current transfer ratio (CTR) of 2000%, maximum collector-emitter voltage of 40 V, and maximum collector current of 200 mA. The device operates within a temperature range of -55°C to +100°C with a power dissipation of 200 mW.
Feature Summary
- High isolation voltage capability for safe signal transmission
- AC input response functionality for direct line interfacing
- Surface-mount Gull-wing lead configuration for automated assembly
Applications
- Industrial control systems requiring galvanic isolation
- Solid-state relay driver circuits
- Microcontroller interface isolation
Procurement Notes
Verify the specific suffix 'A' against the manufacturer's latest datasheet to confirm pinout and packaging details. Ensure compliance with RoHS directives if required by your application standards. Cross-reference the part number with official distributor catalogs to confirm current availability status and lead times before finalizing procurement plans.
Selection Notes
Select this component when high current gain is needed due to the Darlington output structure. The AC input feature simplifies circuit design for mains-connected applications. Consider the surface-mount package type for PCB space constraints. Verify that the 40V collector-emitter voltage rating meets the load requirements of the isolated side.
Part Context
This part belongs to the PS2506/PS2566 family of optocouplers designed for general-purpose isolation. The 'L' designation typically indicates a lead-bending or surface-mount variant compared to through-hole DIP versions. It serves as a bridge between low-voltage digital logic and higher-voltage analog or power circuits.
Replacement Considerations
Direct replacements may include PS2506-1-A for through-hole applications or PS2566L1-1-A for similar surface-mount specifications. Verify pin compatibility and CTR ranges when substituting.
