PS2533L-1-V-F3-A

Overview

The PS2533L-1-V-F3-A is a photovoltaic output optoisolator manufactured by CEL, featuring a GaAs infrared LED coupled with an NPN silicon Darlington connected phototransistor. It provides high isolation voltage of 5000Vrms and supports a collector-emitter voltage (VCEO) of 350 V. The device offers a typical current transfer ratio (CTR) of 4000% and operates in a 4-SMD gull-wing package.

Feature Summary

• High isolation voltage rating of 5000Vrms for safe operation in high-voltage environments
• Darlington output configuration providing high current transfer capability
• Compact surface-mount design suitable for space-constrained applications

Applications

• High-voltage isolation circuits
• Industrial control systems
• Power supply feedback loops

Procurement Notes

Verify the manufacturer designation as CEL or Renesas Electronics, as both entities are associated with this part number in public records. Confirm the specific suffix -V-F3-A matches the required gull-wing package and lead configuration. Check availability status, as some distributors list this component as discontinued or require parametric equivalents. Ensure datasheet specifications align with system requirements before procurement.

Selection Notes

Select this component when high isolation voltage and significant current gain are required in a compact form factor. The Darlington output structure supports higher load currents compared to standard phototransistors. Consider the 4000% typical CTR for signal amplification needs. Verify compatibility with the 4-SMD gull-wing footprint during PCB layout. Evaluate thermal management requirements based on the specific application environment.

Part Context

This optoisolator belongs to the PS2533L series, which includes variants like PS2533L-1-F3-A. The series utilizes GaAs LEDs and silicon Darlington phototransistors. The -V-F3-A suffix typically denotes specific packaging and lead finish options within the product line. These devices are designed for robust electrical isolation between input and output circuits.

Replacement Considerations

Publicly confirmed substitute part numbers include parametric equivalents listed by distributors such as DigiKey. Verify that any replacement maintains the 5000Vrms isolation rating and compatible pinout. Cross-reference the CTR and VCEO specifications to ensure functional parity. Consult manufacturer substitution guides for validated alternatives.
