PS2561DL1-1Y-A

Overview

The PS2561DL1-1Y-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and utilizes a DIP-4 package for through-hole mounting. The device provides high isolation with a rated insulation voltage of 5000 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum collector current of 50 mA, and a power dissipation of 150 mW. The forward current range is specified from 10 mA to 40 mA, with a corresponding forward voltage between 1.2 V and 1.4 V. The current transfer ratio spans from 50% to 160%. Switching characteristics include a typical rise time of 3 µs and a fall time of 5 µs. The component operates within a temperature range of -55°C to +110°C.

Feature Summary

• Provides galvanic isolation via an internal LED and NPN phototransistor structure.
• Supports high-speed switching applications with defined rise and fall times.
• Ensures safety compliance with UL recognized standards for input-output isolation.

Applications

• Industrial automation control systems
• Programmable logic controller (PLC) signal interfaces
• Power supply feedback circuits

Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's latest datasheet to confirm tape-and-reel packaging specifications, as this affects handling procedures. Ensure that the DIP-4 footprint matches the target PCB design constraints. Confirm RoHS compliance status directly with the supplier documentation prior to integration into final assemblies.

Selection Notes

Select this component when a single-channel isolation barrier is required with moderate speed capabilities. The 80 V collector-emitter voltage rating suits low-voltage digital signal transmission. Consider the 5000 Vrms insulation level for safety-critical applications. Evaluate the 50-160% CTR range to ensure adequate drive capability for the downstream load circuitry under varying temperature conditions.

Part Context

This part belongs to the PS2561 series of transistor output optocouplers designed for general-purpose isolation. The DL1 variant specifically denotes the DIP-4 package configuration. The series is engineered for reliability in industrial environments, offering robust performance across wide temperature ranges while maintaining compact physical dimensions suitable for dense circuit board layouts.

Replacement Considerations

Consult official cross-reference lists for direct replacements. Verify pinout compatibility and electrical parameter equivalence before substitution. Ensure any alternative component meets the same insulation voltage and safety certification requirements.
