PS2501L-1-F3-L-A

Overview

The PS2501L-1-F3-L-A is a single-channel transistor output optocoupler manufactured by CEL. It features an NPN silicon phototransistor coupled with a GaAs infrared LED, providing high isolation voltage of 5000 Vrms. The device utilizes a lead bending (gull-wing) package designed for surface mount technology (SMT). Key electrical parameters include a maximum collector-emitter voltage of 80 V and a collector current of 50 mA. The unit operates within a temperature range of -55°C to +100°C.

Feature Summary

High isolation voltage capability for safe signal transmission between isolated circuits
Surface mount gull-wing package design for automated PCB assembly
Optical coupling using GaAs LED and NPN phototransistor for reliable digital switching

Applications

Industrial control systems requiring galvanic isolation
Power supply feedback loops for voltage regulation
Microcontroller input/output interfacing with high-voltage domains

Procurement Notes

Verify the specific suffix 'L-A' against official CEL documentation to confirm lead form and tape/reel packaging specifications. Confirm RoHS compliance status through the manufacturer's latest certification documents. Ensure the sourcing channel provides traceability for this discontinued or limited availability component variant.

Selection Notes

Select this component when surface mount assembly is required for single-channel isolation applications. The gull-wing package facilitates SMT processes compared to standard DIP variants. Verify that the 5000 Vrms isolation rating meets the safety requirements of the target application circuit. Check compatibility with the system's operating temperature range.

Part Context

This part belongs to the PS2501L series of high-isolation voltage photocouplers. The series includes variants with different lead forms and packaging options. The PS2501L designation specifically indicates the lead bending type suitable for surface mounting, distinguishing it from the through-hole PS2501-1 models.
