Overview
The USBUF01P6 is an EMI filter and line termination device designed for USB upstream ports, manufactured by STMicroelectronics. It provides ESD protection exceeding IEC61000-4-2 Level 4 standards. The component features a complex array diode configuration with two chips per element. It operates within a temperature range of -40°C to 150°C. Key electrical parameters include a minimum breakdown voltage (Vbr) of 7V and a clamp voltage (VC) of 7.95V. The device is housed in a SOT-323 package with six pins, measuring 2.2mm in length, 1.35mm in width, and 1mm in height.
Feature Summary
- Provides EMI/RFI noise suppression for high-density board designs
- Offers line termination tailored to meet USB 1.1 standard requirements
- Delivers ESD protection exceeding IEC61000-4-2 Level 4
Applications
- USB upstream port line termination
- EMI/RFI noise suppression in USB interfaces
- ESD protection for USB data lines
Procurement Notes
Verify current manufacturing status as the USBUF01P6 is listed as obsolete in multiple distributor databases. Confirm availability of alternative packages or series replacements such as the USBUF01W6 if sourcing new production units is required. Ensure compatibility with existing PCB footprints when selecting substitutes.
Selection Notes
Select this component for applications requiring specific line termination for USB upstream ports alongside EMI filtering. Consider the SOT-323 package constraints and the 7V breakdown voltage threshold. Evaluate thermal performance within the specified -40°C to 150°C operating range for the target environment.
Part Context
The USBUF01P6 belongs to the USBUFxxW6 series from STMicroelectronics, which focuses on EMI filters and ESD protectors. This series addresses the need for compact solutions in portable electronics and computer peripherals where space is limited and signal integrity is critical for USB compliance.
Replacement Considerations
Public sources identify the USBUF01W6 as a similar available substitute. Verify pinout and electrical characteristics match before replacement due to potential package differences between P6 and W6 suffixes.
