Overview
The PS2561DL1-1Y-H-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a GaAs infrared emitting diode and an NPN silicon phototransistor within a compact 4-pin DIP package. The device provides electrical isolation with a rated insulation voltage of 5000 Vrms, ensuring safe signal transmission between isolated circuits. It supports a maximum collector-emitter voltage of 80 V and a continuous collector current of 50 mA. The component operates reliably across an ambient temperature range of -55°C to +110°C, making it suitable for industrial applications requiring robust isolation performance.
Feature Summary
- Integrates a GaAs light emitting diode and an NPN silicon phototransistor for efficient optical coupling
- Provides high-voltage isolation capability rated at 5000 Vrms between input and output terminals
- Designed for operation in wide ambient temperature environments up to 110°C
- Utilizes a standard 4-pin DIP package configuration for through-hole mounting
Applications
- Industrial automation control systems

Procurement Notes
Verify the specific suffix 'H' against the official Renesas datasheet to confirm lead-free status and RoHS compliance requirements. Ensure the ordering part number matches the exact package style and marking specifications defined in the product documentation. Cross-reference manufacturer codes to avoid counterfeit components during sourcing.
Selection Notes
Select this component when a single-channel isolation solution with high voltage withstand capability is required. Consider the 5000 Vrms rating for safety-critical interfaces. Evaluate the operating temperature range to ensure compatibility with the target environment. Confirm that the DIP package format aligns with the printed circuit board layout constraints.
Part Context
This device belongs to the PS2561 series of optically coupled isolators from Renesas Electronics. The series includes various package options and performance grades. The DL1 designation typically indicates a specific lead form or packaging variant within the broader product family. It serves as a fundamental building block for galvanic isolation in electronic designs.
Replacement Considerations
Consult the official Renesas replacement guide for verified substitutes. Generic equivalents may not match the specific insulation voltage or temperature ratings. Verify pinout compatibility before substitution.
