NUF2101MT1G

Overview

The NUF2101MT1G is a unidirectional ESD protection diode and USB downstream terminator from onsemi, housed in a TSOP-6 surface-mount package. It operates at a working voltage of 5.25 V with a breakdown voltage of 6 V. The device features a low capacitance of 55 pF and provides electrostatic discharge protection rated at 8 kV (contact) and 15 kV (air gap). It functions within a temperature range of -55°C to +125°C.

Feature Summary

• Integrates ESD suppression with USB termination functionality for signal integrity
• Provides high-level electrostatic discharge protection for sensitive data lines
• Utilizes a compact TSOP-6 surface-mount package for space-constrained designs

Applications

• USB 1.1 downstream port protection
• Cellular phone circuitry
• Wireless equipment interfaces

Procurement Notes

Verify the specific suffix 'MT1G' against official onsemi documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS directives if required by the target market. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and current production status before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring combined ESD protection and impedance matching for USB 1.1 downstream ports. The unidirectional configuration suits single-ended signaling applications. Consider the 55 pF capacitance value for signal speed requirements and verify that the TSOP-6 footprint aligns with the PCB layout constraints of the target electronic device.

Part Context

This component belongs to the NUF series of integrated filters and protectors designed specifically for USB applications. It addresses the need for compact solutions that manage both static discharge events and transmission line reflections simultaneously. The series targets portable electronics where board space is limited and signal integrity is critical for reliable data communication.
