Overview
The PS2561DL1-1Y-Q-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and operates in a DIP-4 package with through-hole mounting. The device provides 5000 Vrms insulation voltage and supports a maximum collector current of 50 mA. Key electrical parameters include a forward current of 40 mA, a forward voltage of 1.2 V, and a collector-emitter voltage rating of 80 V. The current transfer ratio ranges from 100% to 260%.
Feature Summary
- Provides high-voltage isolation between input and output circuits using optical transmission.
- Features an NPN phototransistor output for digital signal switching applications.
- Designed for reliable operation within extended industrial temperature ranges.
Applications
- Industrial automation control systems
- Power supply feedback loops
- Microcontroller interface isolation
Procurement Notes
Verify the specific suffix 'Q' against official Renesas documentation to confirm if it denotes a qualified variant or packaging difference, as distributor listings may not explicitly detail suffix functions. Confirm RoHS compliance status directly from the datasheet. Check current lifecycle status, as availability varies by region and distributor.
Selection Notes
Select this component when a DIP-4 through-hole package is required for PCB assembly. Ensure the circuit design accommodates the 40 mA maximum forward current and 50 mA collector current limits. Verify that the 5000 Vrms isolation rating meets the safety requirements of the application environment.
Part Context
This part belongs to the PS2561 series of transistor output optocouplers from Renesas Electronics. The series is designed for general-purpose isolation tasks. The DL1 designation typically indicates a specific lead form or package variation within the broader product family.
Replacement Considerations
Direct substitutes include PS2561DL-1Y-F3-A and PS2561BL-1-A, provided pinout and electrical ratings are compatible. Verify package compatibility and CTR specifications before substitution.
