PS2535L-1-E3-A

Overview

The PS2535L-1-E3-A is a single-channel transistor output optocoupler featuring an NPN photodarlington detector and a GaAs infrared LED. It provides high isolation voltage of 5000 Vrms and supports a maximum collector-emitter voltage of 350 V. The device operates with a forward current up to 50 mA and delivers a typical current transfer ratio of 1500%, ranging from 400% to 5500%. It is designed for surface mount installation in a compact SMD package, suitable for applications requiring robust electrical isolation and high voltage handling capabilities.

Feature Summary

High isolation voltage capability of 5000 Vrms for safe signal transmission across isolated circuits
NPN photodarlington output structure providing high current transfer efficiency
GaAs infrared LED input source ensuring reliable optical coupling performance
Surface mount packaging design facilitating automated assembly processes

Applications

Industrial control systems requiring galvanic isolation
Power supply feedback loops for voltage regulation
Solid-state relay driver circuits
Microcontroller interface isolation for digital signals

Procurement Notes

Verify the specific suffix E3 against manufacturer documentation to confirm lead-free compliance status. Confirm availability as distribution channels may list this part as discontinued or obsolete. Ensure the ordering code matches the exact pin configuration and packaging type required for your PCB layout. Cross-reference the datasheet revision date to ensure parameter consistency with your design specifications.

Selection Notes

Select this component when high collector-emitter voltage ratings are necessary alongside standard optocoupler functionality. The photodarlington output offers higher gain compared to standard transistor outputs, making it suitable for driving loads directly. Consider the thermal dissipation limits and operating temperature range during circuit design. Verify that the isolation voltage rating exceeds the peak transient voltages present in the application environment.

Part Context

This part belongs to the PS2535L series of multi-photocouplers manufactured by CEL, now part of Renesas Electronics. The series is characterized by high isolation voltage and high collector-emitter voltage capabilities. The PS2535L-1 variant specifically denotes a single-channel configuration within this family, distinguishing it from dual-channel counterparts like the PS2535L-2.
