Product details
Overview
NUP8028MNT1G from onsemi is an 8-channel low-capacitance transient voltage suppressor (TVS) array designed for bidirectional ESD protection of high-speed data lines. It features a maximum clamping voltage of 13 V at 1.6 A, 7–11.5 pF capacitance at 3.0 V reverse bias, and IEC 61000-4-2 compliance up to 30 kV (air) / 18 kV (contact), making it suitable for USB, HDMI, and display interface protection in space-constrained portable electronics.
For engineers reviewing the NUP8028MNT1G datasheet, pinout, applications, or equivalent options, key selection criteria include channel count, clamping performance under 1.6 A surge, low-leakage operation below 1 µA at 3.3 V, and DFN8 package compatibility with fine-pitch PCB layouts for handheld and notebook designs.
Technical Context
This device integrates eight independent TVS diodes in a single DFN8 package with common ground configuration, enabling compact protection of parallel signal lines without cross-talk coupling. Each channel provides symmetrical bidirectional clamping with breakdown voltage between 5.3 V and 5.9 V at 1 mA, and operates reliably across −40°C to +85°C ambient temperature.
The architecture supports fast transient response via low-junction-capacitance design (7–11.5 pF at VR = 3.0 V), minimizing signal integrity impact on high-frequency interfaces. Its 13 V clamping voltage at 1.6 A IPP ensures robust suppression of ESD events while maintaining safe voltage margins for 3.3 V logic systems.

FAQ
What is the maximum clamping voltage of the NUP8028MNT1G under standard test conditions?
The NUP8028MNT1G has a maximum clamping voltage (VC) of 13 V when subjected to a peak pulse current (IPP) of 1.6 A using the 8 × 20 µs waveform. This value is measured per IEC 61000-4-5 and ensures that protected downstream ICs see no more than 13 V during an ESD event. The NUP8028MNT1G maintains this clamping performance across its full operating temperature range of −40°C to +85°C.
Does the NUP8028MNT1G support bidirectional or unidirectional transient suppression?
The NUP8028MNT1G provides bidirectional transient suppression on all eight channels. Each channel consists of a back-to-back diode pair referenced to the common GND pin (Pin 5), enabling protection against both positive and negative voltage transients without requiring polarity-aware layout. This makes the NUP8028MNT1G suitable for AC-coupled or differential signal lines such as USB D+/D− or HDMI TMDS pairs.
What is the capacitance of the NUP8028MNT1G at 3.0 V reverse bias, and why does it matter?
The NUP8028MNT1G exhibits a capacitance of 7.0–11.5 pF at 3.0 V reverse bias and 1 MHz frequency. This low, tightly controlled capacitance minimizes signal distortion and timing skew on high-speed data lines like USB 2.0 and LVDS. Because the NUP8028MNT1G maintains sub-12 pF loading even at operational bias, it avoids degrading eye diagrams or increasing bit error rates in multi-gigabit interfaces.
How many ESD protection channels does the NUP8028MNT1G provide, and how are they configured?
The NUP8028MNT1G integrates eight independent ESD protection channels in a single DFN8 package. Pins 1–4 and 6–8 serve as anode terminals for individual channels, while Pin 5 is the shared cathode (GND). There is no internal connection between the anode pins - each channel operates autonomously, allowing flexible assignment to any eight signal lines needing coordinated ESD defense.
Is the NUP8028MNT1G compliant with IEC 61000-4-2, and what are its certified ratings?
Yes, the NUP8028MNT1G is certified to IEC 61000-4-2 for electrostatic discharge immunity. It achieves 30 kV for air discharge and 18 kV for contact discharge - exceeding Level 4 requirements of the standard. These ratings were verified per the official onsemi datasheet (NUP8028MN/D, Rev. 0, September 2006) and confirm robust protection for end-user accessible ports in consumer and medical electronics where the NUP8028MNT1G is deployed.
