PS2501L-1-M-A

Overview

The PS2501L-1-M-A is a single-channel optically coupled isolator manufactured by CEL. It integrates a Gallium Arsenide (GaAs) infrared light emitting diode with an NPN silicon phototransistor. The device utilizes a lead-bending type Gull-wing package designed for surface mount technology, specifically identified as a 4-DIP configuration with a 7.62mm pitch. Key electrical specifications include a maximum collector-emitter voltage of 80V and a collector current capacity of 50mA. The unit provides an isolation voltage rating of 5000VRMS. Operating temperature range spans from -55°C to +100°C.

Feature Summary

Integrates a GaAs LED with an NPN silicon phototransistor for signal transmission
Features a Gull-wing surface mount package for automated assembly compatibility
Provides high-voltage isolation capability between input and output circuits

Applications

Industrial control systems requiring galvanic isolation
Microprocessor input/output interface circuits
Power supply feedback loops

Procurement Notes

Verify the specific suffix 'M-A' against official CEL documentation to confirm pinout orientation and material compliance details. Ensure the selected variant matches the required surface mount footprint dimensions. Confirm availability status as distribution channels may vary. Cross-reference the manufacturer part number with Renesas Electronics records if necessary, given historical brand transitions in the optocoupler market.

Selection Notes

Select this component when a surface mount solution is required for single-channel isolation applications. The Gull-wing package facilitates PCB mounting compared to through-hole alternatives. Verify that the 80V collector-emitter voltage and 50mA current ratings meet the load requirements. Ensure the operating temperature range of -55°C to 100°C aligns with the environmental conditions of the target application.

Part Context

This component belongs to the PS2501 family of optocouplers, which are widely used for electrical isolation. The 'L' designation typically indicates the lead-bending Gull-wing package style, distinguishing it from standard DIP versions. The series is characterized by its use of GaAs LEDs for efficient light emission and silicon phototransistors for reliable switching performance in digital and analog isolation scenarios.
