Overview
The PVI1050NSTPBFHUMA1 is a photovoltaic output optocoupler manufactured by Infineon Technologies, featuring two independent channels in an SMD-8 package. It provides 2500 Vrms isolation voltage and operates within a temperature range of -40°C to +85°C. The device supports a maximum forward current of 50 mA with a forward voltage of 1.4 V and a reverse voltage rating of 6 V. Classified as a microelectronic relay, it is currently marked as Not Recommended for New Designs (NRND).
Feature Summary
- Photovoltaic output technology enabling contactless switching without mechanical wear.
- Dual-channel configuration providing independent signal isolation paths.
- Surface-mount design suitable for automated PCB assembly processes.
Applications
- Signal isolation in industrial control systems
- Interface circuits for measurement and testing equipment
- Power supply feedback loops requiring galvanic separation
Procurement Notes
Verify component status carefully as this part is designated NRND. Confirm availability through authorized distributors as stock may be limited or discontinued. Ensure final designs account for potential obsolescence and plan for long-term supply chain stability or alternative sourcing strategies before production commitment.
Selection Notes
Select this component when photovoltaic output characteristics are required for zero-drift isolation. Compare against MOSFET-output variants if faster switching speeds are needed. Verify package compatibility with existing footprints and ensure thermal management aligns with the specified operating temperature range for reliable performance.
Part Context
This device belongs to Infineon's photovoltaic isolator family, utilizing Microelectronic Relay (MER) technology. It serves as a solid-state replacement for electromechanical relays in applications demanding high reliability and long life cycles. The series emphasizes low leakage current and high insulation resistance for precision analog signal transmission.
Replacement Considerations
The PVI1050NPBFHKLA1 is listed as a possible replacement option. Evaluate pinout compatibility and electrical specifications before substitution. Note that the original model is NRND, making transition planning essential for ongoing manufacturing requirements.
