Overview
The PS2502L-1-K-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics (formerly CEL). It features an NPN photodarlington output and utilizes a GaAs LED input. Key electrical specifications include a maximum collector-emitter voltage of 40 V, a peak forward current of 80 mA, and a minimum current transfer ratio of 200%. The device offers 5000 Vrms isolation voltage and operates within a temperature range of -55°C to +100°C. It is available in surface-mount packages.
Feature Summary
- High isolation voltage capability for safe signal transmission between isolated circuits
- NPN photodarlington output configuration providing high current gain
- Compact surface-mount design suitable for automated assembly processes
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal interface between microcontrollers and high-voltage loads
Procurement Notes
Verify the manufacturer designation carefully, as this component was originally produced by California Eastern Laboratories (CEL) and is now part of the Renesas Electronics portfolio. Confirm that the specific suffix matches your board layout requirements. Availability may be limited due to lifecycle status; check with authorized distributors for current stock or alternative sourcing options before finalizing designs.
Selection Notes
Select this component when a single channel with high current transfer ratio is required. Ensure the 40 V collector-emitter voltage rating meets the load requirements. Verify that the surface-mount package type fits the PCB footprint constraints. Consider the operating temperature range if the application involves extreme environmental conditions.
Part Context
This part belongs to the PS2502L series of optically coupled isolators. The series includes variants with different channel counts and packaging options. The 'L' suffix typically denotes a specific lead form or package variation compared to standard DIP versions. These devices are designed for general-purpose isolation applications where reliability and compact size are priorities.
Replacement Considerations
Direct substitutes include other PS2502L-1 variants from Renesas/CEL with compatible pinouts and electrical ratings. Cross-reference with equivalent parts from other manufacturers ensuring matching isolation voltage, CTR, and package dimensions.
