PS2561A-1-H-V-A

Overview

The PS2561A-1-H-V-A is a single-channel transistor output optocoupler manufactured by CEL. 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 and a collector-emitter breakdown voltage of at least 70 V. It operates within a temperature range of -55 °C to 100 °C and supports a maximum forward current of 30 mA. The component is UL recognized for safety compliance.

Feature Summary

• High isolation voltage capability of 5000 Vrms
• Integrated GaAs LED and NPN silicon phototransistor
• UL recognized safety certification

Applications

• Industrial control systems requiring signal isolation
• Power supply feedback circuits
• Microcontroller input/output isolation

Procurement Notes

Verify the specific suffix 'H-V-A' against manufacturer documentation to confirm pinout, lead form, and packaging type. Ensure compatibility with required safety standards such as UL or CSA if applicable to the end application. Confirm operating temperature ranges match system requirements.

Selection Notes

Select this component when high voltage isolation is required in a compact single-channel configuration. Consider the 5000 Vrms insulation rating and the 70 V collector-emitter breakdown voltage for circuit design. Verify that the NPN phototransistor output suits the load interface needs.

Part Context

This part belongs to the PS2561A series of photocouplers produced by CEL (California Eastern Laboratories). The series includes various package options such as DIP and surface mount variants. The PS2561A-1-H-V-A specifically denotes a version with defined lead bending and packaging characteristics within this family.

Replacement Considerations

Cross-reference with PS2561A-1-H-A or PS2561AL-1-F3-A for similar functionality. Verify pin compatibility and isolation ratings before substitution.
