PS2501AL-1-P-A

Overview

The PS2501AL-1-P-A is a surface mount optically coupled isolator manufactured by CEL. It integrates a Gallium Arsenide (GaAs) light emitting diode with an NPN silicon phototransistor. The device utilizes a lead bending type Gull-wing package designed for surface mount applications. Key electrical specifications include a 5000Vrms isolation voltage and a maximum output current of 30mA per channel.

Feature Summary

• Optical isolation between input and output circuits
• High dielectric strength insulation barrier
• Surface mount compatible Gull-wing packaging

Applications

• Industrial control systems
• Power supply feedback loops
• Signal isolation in microprocessor interfaces

Procurement Notes

Verify the specific suffix -P-A against manufacturer documentation to confirm the exact pin configuration and reel/tube packaging format. Confirm availability status as distribution channels may list discontinued or obsolete variants. Ensure the component meets required safety certifications for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when surface mount assembly is required for single-channel isolation. Compare the 5000Vrms isolation rating against system safety requirements. Evaluate the 30mA collector current capability against load demands. Consider the GaAs LED efficiency for drive current requirements compared to alternative technologies.

Part Context

This part belongs to the PS2501AL series of NEC/CEL optocouplers. It shares the internal GaAs LED and NPN phototransistor architecture with the through-hole PS2501A-1 variant but differs in physical packaging. The AL designation typically indicates the lead form factor suitable for automated surface mount placement processes.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify parametric equivalence with other 4-SMD transistor output optoisolators if direct replacement is necessary.
