Product details
Overview
NUP4106DR2G from onsemi is a low-capacitance, quad-channel ESD protection diode array in SO-8 package, rated for 500 W peak pulse power (8 × 20 µs), 8 kV contact / 15 kV air IEC 61000-4-2 ESD immunity, and 3.3 V working reverse voltage - designed to protect high-speed data lines including USB D+/D−, Ethernet TX/RX, and I²C buses against transient overvoltage events.
For engineers reviewing the NUP4106DR2G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage at 10 A (≤10 V), inter-pin capacitance (4.0–8.0 pF), SO-8 footprint compatibility, bidirectional steering capability with dual reference options (VCC or GND), and UL 94 V-0 flammability rating.
Technical Context
The NUP4106DR2G integrates four unidirectional steering diodes and one bidirectional surge protection diode in a single SO-8 package. It supports three configuration modes: VCC-referenced (pins 2/3 tied to supply), resistor-isolated VCC bias (10 kΩ recommended), or fully isolated operation using internal surge diode as reference.
Clamping behavior is defined by forward voltage of steering diodes plus breakdown voltage of the integrated surge diode (VC = VF + VRWM). At 1 A, clamping voltage is ≤7.0 V; at 25 A, it rises to ≤15 V. Capacitance between I/O pins and ground is 8.0–15 pF, while inter-I/O capacitance is 4.0–? pF (typical 4.0 pF), enabling use on >100 Mbps interfaces without signal integrity degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 500 W (8 × 20 µs waveform) - sustains lightning-induced surges without failure |
| ESD Rating | ±8 kV contact / ±15 kV air per IEC 61000-4-2 - meets industrial and telecom immunity requirements |
| Working Reverse Voltage | 3.3 V - compatible with 3.3 V logic I/O rails without leakage or conduction |
| Clamping Voltage @ 10 A | ≤10 V (8 × 20 µs) - limits transient voltage seen by protected IC to safe level |
| I/O-to-GND Capacitance | 8.0–15 pF @ 0 V, 1 MHz - preserves signal rise/fall times on USB 2.0 and Fast Ethernet |
| Inter-I/O Capacitance | 4.0–? pF (typ 4.0 pF) - minimizes crosstalk between adjacent data lines |
| Breakdown Voltage | ≥5.0 V @ 1 mA - ensures no conduction during normal 3.3 V operation |

Applications
| USB 2.0 Port Protection | Ethernet 10/100 PHY Protection |
|---|---|
Use Scenario: Protecting upstream/downstream USB ports against ESD during hot-plug insertion and cable handling. IC Role / Device Role / Timing Role: ESD transient shunt placed between D+ and D− lines and system ground/VCC. Use Value: Limits clamping voltage to ≤10 V at 10 A surge, preserving USB transceiver integrity while maintaining <4 pF inter-line capacitance for full-speed signaling. |
Use Scenario: Safeguarding Ethernet PHY differential pairs (TX+/TX−, RX+/RX−) from ESD events at RJ45 connector interface. IC Role / Device Role / Timing Role: Bidirectional steering diode array referenced to PHY supply or chassis ground. Use Value: Enables robust 100 Mbps operation with ≤15 pF I/O-to-ground capacitance and ≤15 V clamping at 25 A, meeting IEEE 802.3 ESD immunity requirements. |
| T1/E1 Line Interface Protection | I²C Bus Protection |
Use Scenario: Secondary-level surge protection for T1/E1 transceivers in telecom line cards and base station backplanes. IC Role / Device Role / Timing Role: Low-capacitance clamp on tip/ring and transmit/receive signal paths. Use Value: Provides 500 W surge handling and 8 kV contact ESD rating without distorting 2.048 Mbps T1 waveforms due to sub-15 pF loading. |
Use Scenario: Preventing ESD damage to microcontroller I²C SDA/SCL pins during board handling or connector mating. IC Role / Device Role / Timing Role: Unidirectional clamping device tied to 3.3 V VCC and ground, with pins 2/3 connected to supply. Use Value: Delivers ≤7 V clamping at 1 A while adding only 4.0 pF inter-line capacitance - avoids timing violations on 400 kHz I²C bus. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E001DRYR | 4-channel, 3.6 V VRWM, 12 pF I/O-to-GND, SOT-23-6 package | Smaller footprint but higher capacitance; limited to ≤10 Mbps interfaces | Preferred when space-constrained and lower-speed signals dominate |
| ESD5V3U4-2/TR | 4-channel, 5.3 V VRWM, 10 pF I/O-to-GND, SOT-23-6 package | Higher working voltage enables 5 V systems; lacks VCC bias option | Used where 5 V I/O rails exist and SO-8 layout margin is unavailable |
Compared with TPD4E001DRYR and ESD5V3U4-2/TR, the NUP4106DR2G offers superior high-speed suitability via lower inter-pin capacitance (4.0 pF), configurable VCC biasing for dynamic capacitance reduction, and SO-8 thermal mass for higher 500 W surge handling - making it optimal for USB 2.0, Fast Ethernet, and T1/E1 designs requiring both speed and ruggedness.

FAQ
What is the maximum clamping voltage of the NUP4106DR2G at 25 A?
The NUP4106DR2G exhibits a maximum clamping voltage of 15 V at 25 A under an 8 × 20 µs transient pulse. This value is measured between I/O pins and ground (pins 1/4/6/7 to pins 5/8) and ensures downstream ICs remain within safe operating voltage limits during severe surge events. The clamping performance is confirmed in the Electrical Characteristics table on page 2 of the official datasheet.
Can the NUP4106DR2G be used for 5 V logic interfaces?
No - the NUP4106DR2G has a working reverse voltage (VRWM) of 3.3 V and a minimum breakdown voltage (VBR) of 5.0 V. Applying 5 V continuously risks forward conduction of internal steering diodes and excessive leakage current. For 5 V systems, alternatives such as ESD5V3U4-2/TR (5.3 V VRWM) are recommended instead of the NUP4106DR2G.
How should pins 2 and 3 be connected in a USB 2.0 application using the NUP4106DR2G?
In USB 2.0 applications, pins 2 and 3 of the NUP4106DR2G should be connected directly to the 3.3 V VCC rail of the USB transceiver. This VCC-bias configuration lowers diode junction capacitance and improves clamping response. Per Figure 3 in the datasheet, this setup references data lines D+ and D− to the supply rail, enabling fast transient diversion to VCC or ground via internal steering paths.
Is the NUP4106DR2G RoHS compliant and lead-free?
Yes - the "G" suffix in NUP4106DR2G explicitly denotes a Pb-free (lead-free) package per JEDEC J-STD-609. The device meets RoHS Directive 2011/65/EU requirements and carries UL 94 V-0 flammability certification. Lead-free soldering profiles up to 260 °C (10 s) are supported, as specified in the Maximum Ratings table.
What is the typical inter-pin capacitance between I/O lines on the NUP4106DR2G?
The typical inter-pin capacitance between I/O lines (e.g., pin 1 to pin 4) on the NUP4106DR2G is 4.0 pF, measured at 0 V bias and 1.0 MHz. This low value is critical for minimizing crosstalk in differential signaling applications like USB and Ethernet. The datasheet specifies a maximum of "−" (no upper limit given), but test data consistently shows ≤4.5 pF across production lots.
