PS2535L-1-V-A

Overview

The PS2535L-1-V-A is a surface-mount optically coupled isolator manufactured by Renesas Electronics Corporation. It integrates a Gallium Arsenide (GaAs) light-emitting diode with an NPN silicon Darlington-connected phototransistor. The device provides high isolation voltage and features a collector-to-emitter saturation voltage of 1V maximum. It operates within a temperature range of -55°C to 100°C. The component utilizes a 4-SMD, Gull Wing package configuration.

Feature Summary

• Optical isolation between input and output circuits using GaAs LED technology
• High current transfer capability via NPN silicon Darlington phototransistor output
• Surface-mount construction for automated assembly processes

Applications

• Industrial automation control systems
• Power supply feedback loops
• Signal isolation in embedded computer interfaces

Procurement Notes

Verify the specific suffix V-A against official Renesas documentation to confirm surface-mount packaging and tape-and-reel availability. Ensure the requested quantity matches standard reel sizes defined in the manufacturer's ordering guide. Cross-reference the date code and lot traceability requirements with your quality management standards before finalizing procurement orders.

Selection Notes

Select this component when high isolation voltage and robust noise immunity are required in compact designs. The Darlington output structure offers higher gain compared to single transistor variants, suitable for driving low-current loads directly. Verify that the surface-mount footprint aligns with existing PCB layout constraints and thermal management strategies.

Part Context

This part belongs to the PS2535 series of optocouplers from Renesas. The series includes through-hole variants such as the PS2535-1. The L-series designation typically indicates lead-free compliance or specific material composition variations within the product line. These devices are designed for general-purpose digital signal isolation applications.

Replacement Considerations

Direct replacements include other 1-channel Darlington output optocouplers with similar isolation ratings and pin configurations. Verify compatibility with existing circuit biasing conditions. Check datasheets for equivalent current transfer ratios and switching speeds to ensure functional parity.
