Product details
Overview
NUP4202W1T2G from onsemi is a low-capacitance, unidirectional ESD protection diode array in SC-88 package, designed to safeguard high-speed data lines against IEC 61000-4-2 Level 4 ESD (±20 kV contact), EFT (40 A), and lightning surges. It features 5 V working peak reverse voltage, 8.5–12.5 V clamping at 5 A, ≤5 pF I/O-to-GND capacitance, and operates from −40 °C to +125 °C junction temperature.
For engineers reviewing the NUP4202W1T2G datasheet, pinout, applications, or equivalent options, this device is selected for USB 2.0, HDMI/DVI, Ethernet 10/100, and T1/E1 interface protection where low clamping voltage, sub-5 pF capacitance, and robust 500 W peak power handling are critical design requirements.
Technical Context
The NUP4202W1T2G integrates four steering diodes and one bidirectional surge protection diode in a single SC-88 package. Its internal configuration enables transient current diversion from I/O pins (1, 3, 4, 6) to either ground (pin 2) or VCC (pin 5), depending on biasing mode - supporting three distinct protection topologies including supply-referenced, resistor-isolated, and fully isolated configurations.
Clamping behavior is defined by the combination of forward voltage drop (VF) of steering diodes and breakdown voltage (VBR = 6.0 V) of the integrated surge diode. At 5 A IPP, VC remains ≤12.5 V; at 1 A IPP, VC is 14.5 V. Junction capacitance is specified as 1.5–3.0 pF between I/O pins and 3.0–5.0 pF between I/O pins and GND at 0 V bias and 1 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Peak Reverse Voltage | 5.0 V - sets minimum DC operating voltage threshold before leakage rises significantly |
| Breakdown Voltage | 6.0 V @ 1 mA - defines onset of avalanche conduction for transient clamping |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DQAR | 4-channel, 5.5 V VRWM, 12 V VC @ 5 A, 0.5 pF typical I/O–GND capacitance | Lower capacitance ideal for USB 3.0/PCIe Gen2, but lower 350 W peak power rating | Select when ultra-low capacitance (<1 pF) is prioritized over 500 W surge capability |
| SZ1.5SMC5.0AT3G | Single-channel, 5.0 V VRWM, 14.4 V VC @ 100 A, 1000 pF typical capacitance, DO-214AB package | Higher power (1500 W), but unsuitable for high-speed data due to excessive capacitance and lack of multi-channel integration | Use only for DC power rail protection where speed is irrelevant and board space allows larger package |
Compared with TPD4E05U06DQAR, NUP4202W1T2G offers higher surge power (500 W vs 350 W) at the cost of slightly higher capacitance - making it better suited for USB 2.0 and HDMI 1.3. Compared with SZ1.5SMC5.0AT3G, NUP4202W1T2G provides integrated 4-channel protection with sub-5 pF capacitance, enabling compact, high-fidelity data line protection impossible with discrete TVS diodes.

FAQ
What is the maximum clamping voltage of the NUP4202W1T2G during an ESD event?
The NUP4202W1T2G delivers a clamping voltage of 8.5–12.5 V at 5 A peak pulse current (8×20 µs waveform), and 14.5 V at 1 A. These values are measured per IEC 61000-4-2 test conditions and represent the maximum voltage imposed on protected circuitry during transient events - critical for ensuring compatibility with 3.3 V and 5 V logic interfaces.
How many data lines can the NUP4202W1T2G protect simultaneously?
The NUP4202W1T2G protects four independent data lines (pins 1, 3, 4, and 6) plus a dedicated power rail reference (pin 5). Its internal architecture routes transients from any I/O pin to either ground (pin 2) or VCC (pin 5), enabling full-port protection for standards such as USB 2.0 (D+/D− plus VBUS/GND) or HDMI (three TMDS pairs plus CEC).
Does the NUP4202W1T2G require external biasing components?
The NUP4202W1T2G supports three bias configurations: direct VCC connection (pin 5 to supply), 10 kΩ isolation resistor (reducing capacitance while maintaining diode bias), or floating VP (pin 5 unconnected) for fully isolated operation. No external capacitors or active biasing circuitry is needed - simplifying layout and reducing BOM count compared to discrete diode arrays.
Is the NUP4202W1T2G compatible with lead-free reflow soldering processes?
Yes, the NUP4202W1T2G is Pb-free and rated for lead-free reflow with a maximum lead solder temperature of 260 °C for 10 seconds. It complies with IPC/JEDEC J-STD-020 moisture sensitivity level 1, allowing indefinite floor life at ≤30 °C/60% RH - eliminating bake requirements prior to assembly.
What is the junction capacitance specification for the NUP4202W1T2G between I/O pins and ground?
The NUP4202W1T2G exhibits 3.0–5.0 pF junction capacitance between each I/O pin (1, 3, 4, 6) and ground (pin 2) at 0 V reverse bias and 1 MHz frequency. This low, tightly controlled capacitance ensures minimal loading on high-speed signals - preserving eye diagram integrity for USB 2.0 (480 Mbps) and HDMI 1.3 (1.65 Gbps) applications.
