PS2503L-1-F3-L-A

Overview

The PS2503L-1-F3-L-A is a single-channel transistor output optocoupler manufactured by CEL. It integrates a GaAs light emitting diode and an NPN silicon phototransistor within a 4-SMD Gull Wing package. Key electrical parameters include a maximum collector-emitter voltage of 40 V, a peak forward current of 80 mA, and a typical forward voltage of 1.1 V. The device offers a minimum isolation voltage of 5000 Vrms and operates across a temperature range of -55°C to 100°C. Typical switching characteristics feature rise and fall times of approximately 20 µs.

Feature Summary

Integrates a GaAs LED with an NPN silicon phototransistor for signal isolation
Provides high insulation voltage capability for safety separation
Designed for surface mount installation using a gull-wing package

Applications

General purpose signal isolation in electronic circuits
Switching applications requiring moderate speed performance
Industrial control systems utilizing surface mount technology

Procurement Notes

Verify the specific suffix 'L-A' against official datasheets to confirm lead configuration and tape/reel specifications. Ensure compatibility with surface mount assembly processes. Confirm RoHS compliance status through manufacturer documentation prior to integration into production designs.

Selection Notes

Select this component when a single-channel isolation solution with moderate switching speeds is required. Consider the 40 V collector-emitter voltage limit and 30 mA output current capacity for circuit design. Evaluate the 5000 Vrms isolation rating against system safety requirements and operating environment conditions.

Part Context

This part belongs to the PS2503L series of multi-photocouplers produced by CEL. The series includes variants with different packaging options such as DIP and SMD configurations. The L-series specifically denotes lead bending types suitable for surface mount applications, distinguishing it from through-hole DIP versions.
