PS2532-1

Overview

The PS2532-1 is a single-channel optically coupled isolator manufactured by CEL. It integrates a Gallium Arsenide (GaAs) infrared emitting diode with an NPN silicon Darlington transistor output. The device provides high isolation voltage of 5000 Vrms and supports a maximum collector-emitter voltage of 300 V. Typical forward current is 80 mA, with a forward voltage of approximately 1.4 V. It offers a high current transfer ratio up to 4000% and operates within a temperature range of -25°C to +70°C.

Feature Summary

• High collector-to-emitter voltage capability of 300 V
• Strong electrical isolation with 5000 Vrms breakdown voltage
• High current transfer ratio for efficient signal transmission

Applications

• Industrial automation control systems
• Power supply feedback loops
• Solid-state relay driver circuits
• Microprocessor input/output isolation

Procurement Notes

Verify the manufacturer marking matches CEL specifications. Confirm the package type is standard DIP-4. Check datasheet revisions for any changes in insulation class or safety approvals. Ensure storage conditions comply with moisture sensitivity levels before soldering.

Selection Notes

Select this component when high voltage isolation and high gain are required in a single channel. Compare CTR ranges against load requirements. Consider thermal dissipation if operating near maximum ratings. Verify compatibility with control logic voltage levels.

Part Context

This part belongs to the PS2532 family of photocouplers. Variants include dual and quad channel versions. The series is designed for general-purpose isolation applications requiring robust performance and compact packaging.

Replacement Considerations

Check pinout compatibility with existing PCB layouts. Verify equivalent isolation voltage and CTR specifications. Ensure replacement parts meet same safety certifications.
