PS2533L-1-F3-K-A

Overview

The PS2533L-1-F3-K-A is a surface-mount transistor output optocoupler manufactured by Renesas Electronics. It integrates a GaAs infrared LED with an NPN silicon Darlington phototransistor in a 4-SMD Gull Wing package. Key electrical specifications include a collector-emitter voltage of 350 V, a maximum forward current of 80 mA, and an isolation voltage of 5000 Vrms. The device exhibits a typical current transfer ratio of 4000%, with a minimum of 1500% and a maximum of 6500%. Operating temperatures range from -55°C to +100°C, with power dissipation rated at 450 mW.

Feature Summary

• High isolation voltage capability of 5000 Vrms for robust circuit separation
• High collector-emitter voltage rating of 350 V suitable for high-side switching
• High current transfer ratio ensuring efficient signal transmission
• Surface-mount Gull Wing package design for automated assembly

Applications

• Industrial motor control systems requiring galvanic isolation
• Power supply feedback loops for voltage regulation
• Solid-state relay driver circuits
• Microcontroller interface circuits for noise immunity

Procurement Notes

Verify the specific suffix K-A against official Renesas documentation to confirm package type and tape-and-reel configuration. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents. Ensure the component source is authorized to avoid counterfeit risks, as this part number may have discontinued variants or equivalent substitutes available from other distributors.

Selection Notes

Select this component when high voltage isolation and high collector voltage are required in a compact surface-mount form factor. The high CTR makes it suitable for driving loads directly without additional amplification. Consider the operating temperature range and power dissipation limits relative to the application environment. Verify pin compatibility if replacing existing designs using similar DIP or SMD optocouplers.

Part Context

This component belongs to the PS2533L series of optically coupled isolators. The series typically features GaAs LEDs paired with NPN Darlington outputs. Variants exist in both DIP and SMD packages, with different suffixes indicating packaging options such as tape-and-reel or bulk quantities. The PS2533L-1-F3-K-A specifically denotes the surface-mount version with specific reel packaging.

Replacement Considerations

Publicly confirmed substitute part numbers are not explicitly listed in the provided source material. Check for parametric equivalents from Renesas or other manufacturers that match the 350V CEO, 5000Vrms isolation, and 4-SMD Gull Wing package dimensions.
