PS2701A-1-V-F3-M-A

Overview

The CEL PS2701A-1-V-F3-M-A is a single-channel optocoupler featuring an AlGaAs infrared LED coupled to a phototransistor output. It provides electrical isolation between input and output circuits with a high isolation voltage rating. The device utilizes a 4-pin DIP package configuration, suitable for through-hole mounting on printed circuit boards. Key electrical characteristics include a collector-emitter breakdown voltage of 80V and a forward current rating for the LED input section. The component is designed for signal transmission in environments requiring galvanic isolation.

Feature Summary

• Integrated AlGaAs infrared light emitting diode for efficient optical coupling
• Phototransistor output stage for digital signal switching applications
• High isolation voltage capability between input and output terminals
• Standard 4-pin dual in-line package for easy PCB integration

Procurement Notes

Verify the specific suffix codes against the manufacturer's latest datasheet to ensure compatibility with required isolation ratings and package variations. Confirm that the ordering code matches the exact pinout and electrical specifications needed for your design. Cross-reference the part number with official CEL documentation to avoid substitutions that may differ in performance or physical dimensions.

Selection Notes

Choose this component when a single channel of isolation is sufficient for the application. Consider the phototransistor output speed and current transfer ratio relative to the load requirements. Ensure the operating temperature range aligns with the environmental conditions of the final assembly. Evaluate the isolation voltage rating against the system's safety standards and noise immunity needs.

Part Context

This part belongs to the PS2701 series of optocouplers manufactured by CEL. The series typically offers various configurations including single and dual channels with different output types.
