PVI5050N

Overview

The PVI5050N is a photovoltaic output optocoupler manufactured by Infineon Technologies. It features a single channel with an isolation voltage of 4000 Vrms and an output voltage of 5 V. The device utilizes MER technology and is housed in an 8-DIP package. It is designed for high-voltage isolation applications requiring reliable signal transmission across electrical barriers.

Feature Summary

• Photovoltaic output architecture for galvanic isolation
• High insulation strength rated at 4000 Vrms
• Single-channel configuration for signal transfer
• MER technology integration

Applications

• High-voltage isolation circuits
• Signal isolation interfaces
• Power supply feedback loops

Procurement Notes

Verify the specific suffix against official datasheets, as variations like PVI5050NSPBF exist with different packaging or status. Confirm the component lifecycle status, as some variants are marked Not Recommended for New Designs (NRND). Ensure the 8-DIP package matches the target PCB footprint requirements before procurement.

Selection Notes

Select this component when high isolation voltage is critical for safety or noise immunity. The photovoltaic output requires external biasing circuitry compared to transistor outputs. Verify that the 5 V output capability aligns with the input stage of the receiving logic or amplifier in the design.

Part Context

This part belongs to Infineon's photovoltaic isolator family, distinct from standard transistor-output optocouplers. It differs from the PVI5050NSPBF variant primarily in packaging and lifecycle status. The technology focuses on providing robust isolation without magnetic coupling elements.
