PS2533-1-V-A

Overview

The PS2533-1-V-A is a transistor output optocoupler manufactured by CEL (formerly NEC/Renesas). It comprises an aluminum gallium arsenide light-emitting diode and an NPN silicon Darlington phototransistor. Key electrical parameters include a collector-to-emitter voltage of 350 V, an isolation voltage of 5000 Vrms, and a current transfer ratio of 4000%. The device features a high CTR range of 80% to 150% at IF=5mA. It is housed in a 4-pin DIP or BSI L SMT package.

Feature Summary

• High collector-to-emitter voltage capability for robust switching applications
• High isolation voltage ensuring safe signal transmission across barriers
• High current transfer ratio providing efficient optical coupling

Applications

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

Procurement Notes

Verify the manufacturer designation carefully, as this component lineage involves transitions between NEC, Renesas Technology Corp, and CEL. Confirm that the specific suffix -V-A corresponds to the required packaging and compliance specifications. Cross-reference with official datasheets from the current rights holder to ensure parameter accuracy before integration into designs.

Selection Notes

Select this component when high voltage isolation and high gain are required in a compact form factor. The Darlington configuration offers significant current amplification suitable for driving loads directly. Ensure the operating temperature range and forward current limits align with the system's thermal and power constraints.

Part Context

This part belongs to the PS2533 family of optically coupled isolators. The family includes variants such as PS2533-1, -2, and -4, differing primarily in the number of channels. The PS2533-1-V-A specifically denotes a single-channel unit with specific lead-free and halogen-free attributes indicated by the suffix.

Replacement Considerations

Direct substitutes may include PS2533-1-A or PS2533L-1 depending on package requirements. Verify pinout compatibility and electrical ratings against the original design specifications before substitution.
