PS2705-1-V-F3-L-A

Overview

The PS2705-1-V-F3-L-A is a single-channel transistor output optocoupler manufactured by CEL. It features AC input response capability and provides high isolation voltage of 3,750 Vrms. The device utilizes an NPN phototransistor output with a typical current transfer ratio (CTR) of 100%. Key electrical parameters include a maximum collector-emitter voltage of 40V, a maximum forward current of 50mA, and a saturation voltage of 300mV. Operating temperatures range from -55°C to +100°C.

Feature Summary

Supports AC input signal detection without additional rectification circuitry
Provides galvanic isolation with high dielectric strength
Delivers standard NPN phototransistor switching output

Applications

AC mains voltage sensing circuits
Solid-state relay driver interfaces
Microcontroller isolation for power supply monitoring

Procurement Notes

Verify the manufacturer designation carefully, as this part number appears in databases linked to both CEL and Renesas Electronics due to historical corporate acquisitions. Confirm RoHS compliance status and specific suffix requirements with the supplier, as availability varies significantly across distributors. Ensure the package type matches the target PCB footprint before ordering.

Selection Notes

Select this component when AC input detection is required directly from the LED side. The 3,750 Vrms isolation rating suits primary-side sensing applications. Compare the 100% typical CTR against designs requiring higher gain or lower sensitivity. Verify that the 40V collector voltage meets the load requirements of the downstream switching circuit.

Part Context

This device belongs to the PS2705 series of optocouplers designed for general-purpose isolation. The series is characterized by its ability to handle AC inputs on the emitter-cathode junction. It serves as a bridge between low-voltage control logic and higher-voltage AC lines, commonly found in industrial control and consumer appliance safety circuits.
