PS2532L-1

Overview

The PS2532L-1 is a single-channel transistor output optocoupler manufactured by CEL. It integrates an NPN silicon Darlington-connected phototransistor with a GaAs light emitting diode. Key electrical parameters include a collector-emitter voltage of 300 V, a typical current transfer ratio of 4000%, and an isolation voltage of 5000 Vrms. The device supports a maximum forward current of 80 mA and operates within a temperature range of -55°C to +100°C.

Feature Summary

• High collector-to-emitter voltage capability for demanding circuit applications
• High current transfer ratio ensuring efficient signal transmission
• Robust insulation voltage providing reliable electrical isolation

Applications

• Industrial control systems requiring high voltage isolation
• Power supply feedback loops
• Solid-state relay drivers

Procurement Notes

Verify the specific suffix and package type against your design requirements, as variations exist within the family. Confirm availability status directly with authorized distributors, as lifecycle stages may affect sourcing. Ensure compliance with RoHS directives if required by your manufacturing standards. Cross-reference datasheet revisions to confirm parameter consistency before finalizing procurement.

Selection Notes

Select this component when high collector-emitter voltage and high CTR are critical. Compare against standard phototransistor outputs if lower voltage tolerance suffices. Verify package compatibility with your PCB layout constraints. Consider thermal dissipation limits in high-density assemblies. Validate isolation voltage ratings against safety standards applicable to your end product.

Part Context

This part belongs to the PS2532L series of multi-photocouplers from CEL. It shares architectural similarities with other members like the PS2532L-2 and PS2532L-4, differing primarily in channel count. The series is designed for general-purpose isolation tasks where high voltage handling and signal integrity are prioritized over speed.
