PS2501L-1-A

Overview

The PS2501L-1-A is a single-channel optocoupler featuring an NPN silicon phototransistor output and a GaAs infrared LED input. It provides a 5000Vrms isolation voltage with a collector-emitter voltage of 80V and maximum DC forward current of 80mA. The device operates within a temperature range of -55°C to +100°C, offering a typical rise time of 3µs and fall time of 5µs.

Feature Summary

• High isolation voltage rating for reliable signal transmission
• Wide operating temperature range suitable for industrial environments
• Fast switching speed with low propagation delay

Applications

• Industrial automation control systems
• Power supply feedback circuits
• Signal isolation in measurement equipment

Procurement Notes

Verify the specific suffix 'A' against the manufacturer's latest datasheet to confirm pinout and packaging details. Check for any Product Change Notifications (PCNs) regarding material or manufacturing site updates. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement.

Selection Notes

Select this component when high isolation voltage and wide temperature operation are required. Compare current transfer ratio specifications against load requirements. Verify that the 80V output voltage rating exceeds the circuit's maximum operating voltage. Consider the surface-mount package type for automated assembly processes.

Part Context

This part belongs to the PS2501 series of optocouplers from Renesas Electronics. The series includes variants with different channel counts and package types. The 'L' suffix typically denotes a specific lead-free or RoHS-compliant version within the product family, distinguishing it from standard plastic DIP packages.

Replacement Considerations

Direct replacements include PS2501-1-A and PS2501AL-1-F3-A. Verify pin compatibility and electrical parameters such as CTR and isolation voltage before substitution.
