PS2561A-1-W-A

Overview

The PS2561A-1-W-A is a single-channel transistor output optocoupler manufactured by CEL (Renesas). It integrates a Gallium Arsenide (GaAs) infrared emitting diode with an NPN silicon phototransistor to provide electrical isolation. The device features a high isolation voltage of 5000 Vrms between input and output circuits. It operates within a temperature range of -55 °C to +100 °C. The component is housed in a plastic DIP package and is designed for cost-effective signal transmission across isolated barriers.

Feature Summary

High isolation voltage capability of 5000 Vrms
Integration of GaAs LED and NPN phototransistor
UL, CSA, and BSI safety approvals

Applications

Industrial control systems
Power supply feedback loops
Signal isolation in communication interfaces

Procurement Notes

Verify the specific suffix 'W' against official Renesas or CEL documentation to confirm package variant and tape/reel specifications. Ensure compliance with RoHS directives if required. Cross-reference the manufacturer part number with current datasheets to validate pinout and thermal characteristics before procurement.

Selection Notes

Select this component when high voltage isolation is required in a compact DIP form factor. Consider the collector-emitter breakdown voltage and current transfer ratio requirements relative to the load. Verify that the operating temperature range meets the environmental conditions of the target application.

Part Context

This part belongs to the NEPOC series of photocouplers from NEC/Renesas. The series includes various package options such as DIP and surface mount variants like the AL2 type. The PS2561A-1 is a standard single-channel version widely used for general-purpose isolation tasks.
