PS2506L-2-A

Overview

The PS2506L-2-A is a two-channel optically coupled isolator manufactured by CEL. It integrates Gallium Arsenide (GaAs) light-emitting diodes with NPN silicon Darlington connected phototransistors. The device utilizes a lead-bending Gull-wing surface mount package designed for long creepage distance, ensuring high isolation voltage of 5000 Vrms. Key electrical characteristics include a typical current transfer ratio (CTR) of 2000%, a maximum collector-emitter voltage of 40V, and a maximum forward current of 80mA. It supports AC input response and features high-speed switching with typical rise and fall times of 100 µs.

Feature Summary

• High isolation voltage capability of 5000 Vrms
• AC input response functionality
• Surface mount Gull-wing package optimized for extended creepage distance

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops
• Signal transmission across isolated grounds

Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging configuration, as standard tube packaging may differ from taping products. Ensure compliance with relevant safety approvals such as UL, CSA, and VDE if required for the target application environment. Cross-reference the datasheet revision to confirm pinout and mechanical dimensions match the design requirements.

Selection Notes

Select this component when dual-channel isolation is necessary within a compact surface-mount footprint. The long creepage distance design makes it suitable for applications demanding enhanced safety clearance. Consider the 2000% typical CTR for driving loads with minimal input current, and verify that the 100 µs switching speed meets the system's timing constraints.

Part Context

This part belongs to the NEPOC series of high-isolation voltage photocouplers. It is part of the PS2506 family, which includes variants with different channel counts and package types. The L-series designation specifically indicates the lead-bending Gull-wing form factor intended for surface mount technology assembly.

Replacement Considerations

Direct substitutes include other PS2506L-2 variants from CEL or Renesas, provided the package and isolation ratings match. Verify compatibility with equivalent parts from other manufacturers by comparing pin configurations, isolation voltages, and current transfer ratios.
