PS2801A-1-A

Overview

The PS2801A-1-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a forward current of 30 mA, and a forward voltage of 1.4 V. The device provides an isolation voltage of 2500 Vrms and has a power dissipation rating of 60 mW. Current transfer ratio ranges from 50% to 400%, with switching times of 5 µs rise and 7 µs fall.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits
• Utilizes a small and thin SSOP-4 surface mount package for dense applications
• Incorporates ambient light shielding to prevent interference

Applications

• Programmable logic controllers
• Measurement instruments
• Power supply units

Procurement Notes

Verify the Not Recommended for New Design (NRND) status before implementation. Confirm RoHS compliance details via official documentation. Ensure the SSOP-4 package matches PCB footprint requirements. Validate that the 70 V collector-emitter voltage meets circuit specifications.

Selection Notes

Select this component for single-channel isolation needs requiring a compact form factor. The 2500 Vrms isolation rating suits general industrial applications. Consider the 50% to 400% current transfer ratio for signal transmission efficiency. Verify thermal management capabilities given the 60 mW power dissipation limit.

Part Context

This part belongs to the PS2801A-1 series of high-isolation voltage photocouplers. It shares the SSOP-4 package family with other variants in the lineup. The series is designed for applications requiring reliable signal transmission across isolated boundaries.

Replacement Considerations

Check for direct pin-compatible substitutes within the same series. Verify if updated revisions offer improved availability or performance metrics.
