PUSB3FR6Z

PUSB3FR6Z appears to be a vendor-specific SKU rather than a universal part number. Without a manufacturer or datasheet, its exact function is unclear; it could be a USB-related component (protection, switch, filter, etc.) or another interface device, in a particular package.
How to get a precise introduction:
- Search the exact string in distributor catalogs (DigiKey, Mouser, Arrow) and the manufacturer’s site for a datasheet.
- Identify the device family, pinout, electrical ratings, and packaging from the datasheet.
- Check the BOM or schematic where the part is used to confirm its role.
- Ask the supplier for cross-references or a datasheet if needed.
If you can share the manufacturer, board context, or any markings, I can provide a concrete, concise description.

I can’t determine pin count or function from the code alone. “PUSB3FR6Z” could refer to different parts from different manufacturers (e.g., USB protection arrays, fuses, etc.). Please share the manufacturer or a link to the datasheet, and I’ll give the exact pin count and function.

If PUSB3FR6Z is a USB protection device (PTC resettable fuse), typical applications include:
- Overcurrent protection for USB power rails in USB 3.x interfaces
- Protection for USB ports in desktops, laptops, USB hubs, and docking stations
- Power protection in USB chargers, power banks, embedded systems, and IoT devices
- Suitable for automotive and industrial equipment with USB power lines
- Used in printers, cameras, wearables, and other consumer electronics with USB power connections

The package type for PUSB3FR6Z varies by manufacturer; parts with that number can come in different packages. Please provide the supplier or a datasheet/link, and I’ll confirm the exact package (e.g., SOT-23, QFN, SOIC, etc.).
