PS2501L-1-E3-H-A

Overview

The PS2501L-1-E3-H-A is a single-channel transistor output optocoupler manufactured by CEL. It integrates an aluminum gallium arsenide (AlGaAs) light-emitting diode with an NPN silicon phototransistor to provide electrical isolation. The device features a gull-wing surface-mount package and offers high insulation voltage of 5000 Vrms. Key electrical parameters include a collector-emitter voltage of 80V, a maximum forward current of 50mA, and a typical current transfer ratio of 100% at a forward current of 5mA. The unit operates within a temperature range of -55°C to +100°C.

Feature Summary

Integrates AlGaAs LED and NPN phototransistor for signal isolation
Provides 5000 Vrms insulation voltage between input and output
Utilizes gull-wing lead bending type for surface mount applications

Applications

Industrial control systems requiring noise suppression
Signal isolation in measurement circuits
Power supply feedback loops

Procurement Notes

Verify the specific suffix 'E3-H-A' against official datasheets to confirm compliance with RoHS directives and lead-free specifications. Ensure the gull-wing package variant matches the intended PCB footprint requirements. Confirm availability status as this component series may have limited stock or end-of-life implications depending on the region.

Selection Notes

Select this component when high isolation voltage and surface-mount compatibility are required. The NPN phototransistor output suits digital switching applications. Verify that the 80V collector-emitter voltage rating meets the load requirements. Consider the thermal performance within the specified operating temperature range for reliable long-term operation.

Part Context

This part belongs to the PS2501L family of single-channel optocouplers from CEL. These devices are designed for general-purpose isolation tasks. The L-series designation indicates the specific gull-wing surface-mount package style, distinguishing it from through-hole DIP variants within the same product line.
