Overview
The PVI5050NPBF is a single-channel photovoltaic isolator manufactured by International Rectifier. It features an integrated photovoltaic generator that produces a 5V output, driven by a GaAlAs LED for optical isolation. The device operates within a temperature range of -40°C to +85°C and provides 4000Vrms isolation voltage. Packaged in an 8-DIP format, it serves as a gate driver for power MOSFETs or IGBTs.
Feature Summary
- Provides direct gate drive capability for power switching devices without external bias supplies
- Ensures high-voltage electrical isolation between control circuits and power stages
- Utilizes monolithic photovoltaic generation technology for reliable signal transmission
Applications
- Solid-state relay (SSR) gate driving
- High-voltage power supply control loops
- Industrial motor drive isolation interfaces
Procurement Notes
Verify the component status as NRND (Not Recommended for New Designs) before finalizing procurement plans. Confirm RoHS compliance and lead-free specifications match project requirements. Ensure the 8-DIP package dimensions align with existing PCB footprints. Validate that the 4000Vrms isolation rating meets safety standards for the intended application environment.
Selection Notes
Select this component when a self-powered optocoupler solution is required to simplify gate driver circuitry. It is suitable for applications needing robust isolation without complex auxiliary power supplies. Consider the single-channel configuration and 5V output level against system voltage requirements. Evaluate thermal performance within the specified operating temperature range for long-term reliability.
Part Context
This part belongs to the PVI series of photovoltaic isolators designed by International Rectifier. These devices integrate a photovoltaic generator with an input LED to create isolated drivers. The series supports both single and dual-channel configurations for various power electronics applications requiring galvanic isolation.
Replacement Considerations
Check for updated Infineon datasheets regarding lifecycle management due to NRND status. Verify pin compatibility if substituting with other PVI series variants like PVI5050NSPBF.
