PS2502-1-A

Overview

The PS2502-1-A is a single-channel photodarlington output optocoupler manufactured by Renesas Electronics. It features an isolation voltage of 5000 Vrms and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a minimum current transfer ratio of 200% at 1 mA, a maximum collector-emitter saturation voltage of 1 V, and a peak forward current of 80 mA. The device supports a maximum collector current of 200 mA with a collector-emitter breakdown voltage of 40 V.

Feature Summary

• High current transfer ratio capability for efficient signal transmission
• Robust insulation voltage rating for safe circuit isolation
• Wide operating temperature range suitable for demanding environments

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops
• Signal interface between microcontrollers and high-voltage circuits

Procurement Notes

Verify the specific suffix (e.g., -A, -RJ) against the datasheet to ensure correct packaging and compliance status. Confirm RoHS and REACH declarations as required by regional regulations. Check the part status, as this component may be designated as Not For New Designs in some distributor catalogs. Ensure the ordering quantity matches the factory pack size specified in the official documentation.

Selection Notes

Select this component when a high CTR photodarlington output is required for single-channel isolation. Compare the 5000 Vrms isolation rating against system safety requirements. Evaluate the 200 mA collector current limit against load demands. Consider the DIP-4 package constraints for PCB layout. Verify compatibility with the driving voltage and current limits of the input LED side.

Part Context

This part belongs to the PS2502L series of transistor output optocouplers from Renesas Electronics. The series includes variants with different channel counts and package styles. The PS2502-1-A specifically denotes the single-channel configuration in a standard DIP-4 package. It is designed for general-purpose isolation applications where high reliability and wide temperature operation are necessary.

Replacement Considerations

Check for direct substitutes within the PS2502L family, such as PS2502L-1-A, noting any differences in suffixes or manufacturing updates. Verify pinout compatibility before substitution. Consult the manufacturer's PCN documents for any lifecycle changes or recommended replacements if the part is obsolete.
