PS2501L-4

Overview

The PS2501L-4 is a photovoltaic output optoisolator manufactured by CEL. It integrates a Gallium Arsenide (GaAs) infrared light-emitting diode with an NPN silicon phototransistor within a single package. The device provides electrical isolation between input and output circuits via optical coupling. It features a lead bending type, specifically gull-wing configuration, designed for surface mount technology applications. This component serves as an optically coupled isolator suitable for various electronic systems requiring signal transmission across isolated boundaries.

Feature Summary

Integrates a GaAs LED and NPN silicon phototransistor for optical signal transmission
Provides galvanic isolation between input and output circuits
Features gull-wing leads designed for surface mount assembly

Applications

Signal isolation in industrial control systems
Interface circuits for microprocessors and logic devices
Power supply feedback loops

Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and packaging variations. Ensure compatibility with surface mount reflow profiles. Confirm manufacturer documentation for RoHS compliance status if required by design specifications. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when surface mount isolation is required for low-speed digital signals. Consider the photovoltaic output characteristics for applications needing high linearity or zero leakage current without bias voltage. Evaluate the isolation voltage rating against system safety requirements. Compare package dimensions against PCB footprint constraints before finalizing the design.

Part Context

This part belongs to the PS2501 family of optocouplers produced by California Eastern Laboratories (CEL), now part of Renesas Technology. The family includes variants with different pin counts and packaging styles. The PS2501L-4 specifically denotes the four-channel variant in a lead-bending surface mount package, distinguishing it from through-hole DIP versions.
