PS2561AL2-1-E3-A

Overview

The PS2561AL2-1-E3-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and operates with a maximum collector-emitter voltage of 70 V and a collector current of 30 mA. The device provides high insulation capability with a rated isolation voltage of 5000 Vrms. It supports a forward current of 10 mA with a typical forward voltage of 1.2 V. The unit is housed in a DIP-4 Gull Wing package suitable for surface mount installation. Operating temperatures range from -55°C to +100°C, with a power dissipation rating of 150 mW.

Feature Summary

Provides electrical isolation between input and output circuits using an infrared LED and NPN phototransistor configuration.
Offers high dielectric strength with a 5000 Vrms insulation voltage rating for safety-critical applications.
Designed for surface mount technology (SMD/SMT) integration into compact printed circuit boards.

Applications

Industrial control systems requiring signal isolation
Power supply feedback loops
Microcontroller interface circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead-free specifications against the official datasheet. Check for obsolescence notices as this part may be subject to discontinuation. Ensure packaging integrity upon receipt to prevent damage to the delicate internal components during handling and assembly processes.

Selection Notes

Select this component when high isolation voltage is required in a small surface-mount footprint. Compare CTR specifications against load requirements to ensure adequate switching performance. Verify thermal management capabilities within the 150 mW power dissipation limit. Consider alternative packages if through-hole mounting is preferred over SMD configurations.

Part Context

This device belongs to the PS2561A series of transistor output optocouplers. It shares functional similarities with other variants in the family but differs in specific electrical parameters and packaging options. The series is designed for general-purpose isolation tasks in industrial and consumer electronics applications.
