PS2565-1Y-A

Overview

The PS2565-1Y-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 80 V, a maximum collector current of 50 mA, and a typical current transfer ratio of 200%. The device provides 5000 Vrms isolation voltage and supports AC/DC input types. Switching characteristics consist of a 3 µs rise time and a 5 µs fall time. Power dissipation is rated at 150 mW, with a forward voltage of 1.17 V at a forward current of 10 mA.

Feature Summary

• Provides high-speed switching capabilities for signal transmission applications
• Ensures electrical safety through robust insulation voltage between input and output circuits
• Supports both AC and DC input signal configurations for versatile integration

Applications

• Telephone and fax equipment interfaces
• Factory automation and office automation systems
• Programmable logic controller (PLC) signal isolation

Procurement Notes

Verify the specific ordering suffix against official Renesas documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure the selected variant matches the required lead frame material and marking configuration for the target assembly process.

Selection Notes

Select this component when a single-channel isolation barrier is required with moderate speed performance. Consider the DIP-4 package constraints for through-hole mounting designs. Evaluate the 80 V collector-emitter voltage rating against load requirements. Verify that the 150 mW power dissipation limit accommodates the thermal environment of the final enclosure.

Part Context

This part belongs to the PS2565 series of multi photocouplers designed for general-purpose isolation. The series includes variants with different packaging options such as surface mount and standard DIP configurations. These components are engineered to meet international safety standards for industrial and consumer electronics applications requiring reliable signal transfer across isolated domains.

Replacement Considerations

Consult official cross-reference lists for parameter-equivalent alternatives. Verify pinout compatibility and isolation voltage ratings before substituting. Ensure replacement parts maintain identical switching times and current transfer ratios to preserve circuit timing integrity.
