Product details
Overview
NUP4201MR6T1G from onsemi is a unidirectional transient voltage suppressor (TVS) diode array designed for ESD protection of high-speed data lines, featuring 5 V working peak reverse voltage, 12.5 V clamping voltage at 5 A, and ultra-low junction capacitance of 1.5–3.0 pF between I/O pins. It protects four data lines in USB 2.0, DVI, and Ethernet interfaces while maintaining signal integrity.
For engineers reviewing the NUP4201MR6T1G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage under IEC 61000-4-2 Level 4 (±20 kV contact), low capacitance for <480 Mbps data rates, TSOP-6 footprint compatibility with SC-74/SOT-23-6, and integrated steering diodes + TVS architecture for rail-to-rail transient diversion.
Technical Context
The NUP4201MR6T1G implements a unidirectional TVS array with four independent I/O channels (pins 1, 3, 4, 6), a common ground reference (pin 2), and a VCC bias terminal (pin 5). Its internal structure combines fast-switching steering diodes and a robust 500 W peak power TVS element to clamp transients to ≤12.5 V at 5 A.
It supports three configuration modes: VCC-referenced protection (pin 5 tied to supply), resistor-isolated bias (10 kΩ series), or fully isolated operation (pin 5 NC). Clamping behavior is defined by VF + VTVS, not VCC ± VF, eliminating supply rail coupling during ESD events.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E001DRYR | Unidirectional, 5.5 V VRWM, 15 V VC @ 5 A, 0.5 pF I/O–GND | Lower capacitance but higher clamping; optimized for USB 3.0 (5 Gbps) where 12.5 V clamping is acceptable | Select when prioritizing <0.6 pF for Gen 1+ SuperSpeed; verify system-level ESD margin with 15 V clamping |
| SZ1.5SMC5.0AT3G | Single-channel, 5.0 V VRWM, 14.4 V VC @ 100 A, 100 pF typical | Higher power (1500 W) but 30× higher capacitance; suitable only for low-speed power rails, not data lines | Use only for VBUS or DC supply rail protection-not for high-speed data; requires separate channel per line |
Compared with TPD4E001DRYR, the NUP4201MR6T1G offers lower clamping (12.5 V vs. 15 V) at the cost of slightly higher capacitance (1.5–3.0 pF vs. 0.5 pF), making it better suited for USB 2.0/DVI where clamping margin is critical. Versus SZ1.5SMC5.0AT3G, it provides true multi-channel integration and data-line-optimized capacitance, eliminating four discrete TVS placements.

FAQ
What is the maximum clamping voltage of the NUP4201MR6T1G under IEC 61000-4-2 ESD conditions?
The NUP4201MR6T1G exhibits a clamping voltage of ≤16.6 V at 1 A and ≤12.5 V at 5 A under the 8×20 µs pulse waveform per Figure 5 in its datasheet. For IEC 61000-4-2 contact discharge (±8 kV), oscilloscope screenshots (Figures 1–2) confirm clamping remains below 16 V across the full event duration, ensuring protected ICs stay within safe operating limits. This performance is guaranteed for the NUP4201MR6T1G across −40°C to +125°C junction temperature.
Can the NUP4201MR6T1G protect both power and data lines simultaneously?
Yes-the NUP4201MR6T1G integrates four data-line steering diodes and one TVS element in a single TSOP-6 package. When pin 5 is connected to VCC, the internal TVS protects the power rail from overvoltage, while the steering diodes divert ESD from I/O pins 1/3/4/6 to either VCC or ground (pin 2). This dual-role capability eliminates the need for separate power-rail TVS diodes, reducing component count and PCB area in designs such as USB 2.0 ports where both VBUS and D+/D− require protection.
Is the NUP4201MR6T1G pin-compatible with standard SOT-23-6 ESD protection devices?
Yes-the NUP4201MR6T1G uses the TSOP-6 package (Case 318G), which is explicitly stated in its datasheet to be footprint compatible with SC-74, SC-59, and SOT-23-6 6-lead packages. Pin assignments match Style 12 in the generic marking diagram: pin 1 = I/O, pin 2 = GROUND, pin 3 = I/O, pin 4 = I/O, pin 5 = VCC, pin 6 = I/O. This allows direct substitution into existing layouts without trace modifications, provided the original device also used this pinout configuration.
What is the recommended PCB layout practice for optimal ESD performance of the NUP4201MR6T1G?
For optimal ESD performance, connect pin 2 (VN) directly to a low-inductance ground plane using multiple vias; keep all I/O traces as short and straight as possible (<5 mm preferred); place the NUP4201MR6T1G within 3 mm of the protected connector; avoid routing sensitive signals under or near the device body; and use thermal relief on pin 2 pads to maintain solder joint integrity without sacrificing grounding. These practices minimize parasitic inductance that could elevate clamping voltage beyond the rated 12.5 V during nanosecond-scale ESD events.
Does the NUP4201MR6T1G meet automotive AEC-Q200 requirements?
No-the NUP4201MR6T1G is not qualified to AEC-Q200. Its datasheet specifies an operating junction temperature range of −40°C to +125°C and storage range up to +150°C, but it lacks AEC-Q200 stress test reporting (e.g., temperature cycling, humidity bias, mechanical shock). For automotive applications requiring AEC-Q200 compliance, consider onsemi's automotive-grade equivalents such as the ESD7L5.0DT5G, which shares similar electrical specs but carries full qualification documentation. The NUP4201MR6T1G remains suitable for industrial and consumer-grade systems operating within its specified temperature and reliability envelope.
