PVI5080

Overview

The PVI5080 is a photovoltaic isolator manufactured by Infineon Technologies. It generates an electrically isolated DC voltage upon receipt of a DC input signal, functioning as a microelectronic relay. The device features an isolation voltage of 4000 Vrms and provides a single output with an output voltage of 5 V. It utilizes MER technology for signal transmission.

Feature Summary

• Generates electrically isolated DC voltage from DC input signals
• Functions as a solid-state microelectronic relay
• Provides high-voltage isolation between input and output circuits

Applications

• Solid-state relay replacement in industrial control systems
• High-voltage isolation interfaces in measurement equipment
• Signal coupling in environments requiring galvanic isolation

Procurement Notes

Verify the specific suffix (e.g., NPbF, NSPbF) against the required package type, as the base part number may refer to multiple physical variants. Confirm current production status, as this component series may be obsolete or not recommended for new designs. Ensure compatibility with existing PCB footprints if replacing older units.

Selection Notes

Select based on the required isolation voltage rating of 4000 Vrms and the specific output configuration. Consider the package style (DIP vs. SMD) relative to assembly methods. Verify that the 5 V output level meets the downstream circuit requirements without additional conditioning.

Part Context

This component belongs to the PVI series of photovoltaic isolators from Infineon Technologies. These devices are designed to replace mechanical relays in applications where silent operation, long life, and fast switching are beneficial. The series emphasizes robust electrical isolation capabilities.
