Overview
The PS2502-4 is a four-channel optically coupled isolator manufactured by California Eastern Laboratories (CEL). It integrates a Gallium Arsenide (GaAs) infrared light emitting diode with an NPN silicon Darlington phototransistor array. The device provides high isolation voltage of 5,000 Vrms and features a typical current transfer ratio of 2,000%. Switching characteristics include typical rise and fall times of 100 μs. It is available in 16-pin DIP or surface mount packages.
Feature Summary
- Contains four independent channels for multi-signal isolation
- Utilizes GaAs LED and NPN silicon Darlington phototransistors
- Provides high isolation voltage capability
Applications
- Industrial control systems requiring multi-channel isolation
- Data communication interfaces
- Power supply feedback circuits
Procurement Notes
Verify the manufacturer designation on the component marking, as CEL products are often distributed under NEC or Renesas branding due to corporate acquisitions. Confirm the package type matches your PCB footprint requirements, specifically distinguishing between standard DIP and SMT variants. Ensure the ordering suffix corresponds to the desired tape-and-reel or tube packaging configuration before finalizing procurement orders.
Selection Notes
Select this component when four isolated channels are required within a single package to save board space. The high current transfer ratio makes it suitable for driving loads directly without additional amplification stages. Consider the 100 μs switching speed limitations; this part is not suitable for high-frequency digital signals but is appropriate for slower control applications.
Part Context
This component belongs to the PS2502 series of high-density mounting photodarlington optically coupled isolators. The series includes single and dual channel variants (PS2502-1, PS2502-2) and low-profile versions (PS2502L). The four-channel configuration offers a compact solution for applications needing multiple isolated outputs compared to using discrete single-channel devices.
Replacement Considerations
Cross-reference with PS2502-4-A or PS2502L-4 if specific pinout or package height variations are required. Verify compatibility with NEC/NEC Electronics original specifications if sourcing from legacy distributors.
