PS2561L-2-V-A

Overview

The PS2561L-2-V-A is a surface-mount transistor output optocoupler manufactured by CEL. It integrates an AlGaAs light-emitting diode and an NPN silicon phototransistor within a compact 8-SMD package. The device provides high isolation voltage of 5000 Vrms between input and output channels. It features two independent channels, each capable of handling a maximum collector current of 50 mA and a collector-emitter voltage of 80 V. The unit operates reliably across a wide temperature range from -55°C to +100°C.

Feature Summary

Dual-channel configuration for simultaneous signal isolation
High dielectric strength with 5000 Vrms insulation capability
Surface-mount construction for automated assembly

Applications

Industrial control systems requiring galvanic isolation
Power supply feedback loops
Signal transmission in noisy environments

Procurement Notes

Verify the manufacturer designation on the component marking, as this part number appears in catalogs from multiple suppliers including CEL and Renesas. Confirm that the specific suffix corresponds to the desired packaging format and compliance status. Ensure the source document explicitly identifies CEL as the producer for this exact SKU to avoid substitution errors.

Selection Notes

Select this component when dual-channel isolation is required in a small footprint. The NPN phototransistor output suits digital switching applications. Consider the operating temperature range and isolation voltage requirements against the system's electrical stress levels. Verify pinout compatibility with the target PCB layout before finalizing the design.

Part Context

This device belongs to the PS2561L series of high-isolation voltage optocouplers. The 'L' designation indicates a lead-bending type suitable for surface mount technology. The '2' signifies a dual-channel arrangement within a single package. This series is designed to replace older DIP-based isolators in space-constrained modern electronics.
