Product details
Overview
NUP4108W5T2G from onsemi is a low-capacitance quad unidirectional ESD protection diode array in SC−88A (SOT−353) package, rated for 6.4–7.1 V breakdown voltage, 13 V clamping at 1.6 A, and 12 pF typical junction capacitance at 0 V bias. It delivers IEC 61000−4−2 Level 4 and MIL−STD−883C Class 3 ESD protection for high-speed data lines in space-constrained portable electronics.
For engineers reviewing the NUP4108W5T2G datasheet, pinout, applications, or equivalent options, key selection criteria include its 12 pF max capacitance at 1 MHz, 1.0 µA leakage at 5.0 V, 380 mW steady-state power per diode, and verified performance in USB 2.0, HDMI, and serial port interface protection.
Technical Context
This device integrates four independent unidirectional TVS diodes in a single SC−88A package, each with a nominal 6.8 V breakdown voltage and sub-13 V clamping under 1.6 A 8/20 µs surge current. Its low 12 pF capacitance enables use on high-speed signal lines without signal integrity degradation.
The NUP4108W5T2G operates across −40°C to +125°C junction temperature and supports FR4 PCB mounting with 327°C/W thermal resistance. It is Pb−free, RoHS compliant, and qualified per JEDEC standards for surface-mount reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage | 6.4–7.1 V at 1 mA - defines minimum overvoltage threshold before conduction begins |
| Clamping Voltage | ≤13 V at 1.6 A 8/20 µs pulse - limits transient voltage seen by protected IC |
| Junction Capacitance | 12 pF max at 0 V, 1 MHz - preserves signal integrity on USB/HDMI/UART lines |
| Leakage Current | ≤1.0 µA at 5.0 V reverse - minimizes standby power loss in battery-powered systems |
| Power Dissipation | 380 mW per diode - sets continuous thermal limit for single-line operation |
| ESD Rating | IEC 61000−4−2 Level 4 (±15 kV air / ±8 kV contact) - meets industrial end-equipment immunity requirements |

Applications
| USB 2.0 Interface Protection | HDMI Data Line Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 ports in notebooks and docking stations from ESD discharge during cable insertion. IC Role / Device Role / Timing Role: Transient voltage suppressor placed directly at connector, clamping fast ESD pulses before they reach USB transceiver IC. Use Value: 12 pF capacitance avoids signal distortion; 13 V clamping ensures PHY-level logic remains within safe operating voltage. | Use Scenario: Shielding TMDS clock and data pairs in HDMI 1.4 interfaces of monitors and media players from contact ESD. IC Role / Device Role / Timing Role: Unidirectional TVS array connected between each TMDS differential pair and ground, preserving common-mode noise rejection. Use Value: Low leakage (<1 µA) prevents DC bias shift; quad layout matches HDMI's 3 data + 1 clock lane count. |
| Serial Port (RS-232/UART) Protection | Industrial Sensor Interface Protection |
Use Scenario: Safeguarding TX/RX/CTS/RTS lines of RS-232 or UART peripherals in factory automation controllers. IC Role / Device Role / Timing Role: Discrete line protection element mounted adjacent to connector, shunting ESD energy to chassis ground. Use Value: 6.8 V breakdown aligns with ±5 V to ±15 V RS-232 signaling range; SC−88A size fits tight connector footprints. | Use Scenario: Protecting analog sensor inputs (e.g., thermocouple, pressure transducer) in medical diagnostic devices from handling ESD. IC Role / Device Role / Timing Role: Front-end ESD clamp on low-bandwidth analog signal paths prior to instrumentation amplifier input stage. Use Value: Sub-1 µA leakage avoids measurement offset errors; 125°C max junction temperature supports sterilization environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z5.0T1G | Single-channel, 5.0 V breakdown, 10 pF capacitance, SOD-523 package | Requires four discrete placements vs. quad integration; lower capacitance but higher board area usage | Preferred where ultra-low capacitance (<10 pF) is critical and layout allows discrete placement |
| TPD4E001DRYR | Quad-channel, 5.5 V breakdown, 3.5 pF capacitance, X2SON-8 package | Lower capacitance and tighter tolerance, but requires different footprint and ground pad design | Selected when protecting >1 Gbps interfaces like USB 3.0 or DisplayPort where <4 pF is mandatory |
Compared with NUP4108W5T2G, ES5Z5.0T1G trades integration for lower capacitance per channel, while TPD4E001DRYR offers superior high-speed performance at the cost of non-drop-in layout changes and higher unit cost.

FAQ
What is the maximum clamping voltage of the NUP4108W5T2G under standard ESD test conditions?
The NUP4108W5T2G exhibits a maximum clamping voltage of 13 V when subjected to a 1.6 A, 8/20 µs current waveform - the standardized surge condition defined in IEC 61000−4−5. This value is measured at the device terminals and ensures downstream ICs experience limited overvoltage stress during transient events. The NUP4108W5T2G maintains this clamping performance across its full operating temperature range.
Does the NUP4108W5T2G support bidirectional signal lines such as USB D+ and D−?
No, the NUP4108W5T2G implements a unidirectional configuration: each of its four channels has an anode input and shares a common cathode. For true bidirectional protection of differential pairs like USB D+/D−, two NUP4108W5T2G devices are required - one for positive swing clamping and another for negative swing - or a dedicated bidirectional array must be selected. The NUP4108W5T2G itself is not rated for reverse conduction.
What is the thermal resistance (RJA) of the NUP4108W5T2G on a standard FR4 PCB?
The NUP4108W5T2G has a specified junction-to-ambient thermal resistance (RJA) of 327°C/W when mounted on a standard FR4 board with minimum copper pad area. This value assumes no additional thermal relief or copper pour. Designers should apply the 3.05 mW/°C derating factor above 25°C ambient to maintain safe junction temperatures. The NUP4108W5T2G's thermal performance is validated per JEDEC JESD51-2 standards.
Can the NUP4108W5T2G be used to protect 3.3 V logic interfaces?
Yes, the NUP4108W5T2G is compatible with 3.3 V logic interfaces. Its 6.4–7.1 V breakdown voltage ensures it remains non-conductive during normal 3.3 V operation, while its ≤13 V clamping voltage provides safe margin below typical 3.3 V IC absolute maximum ratings (often 4.6 V or 5.5 V). System-level validation is required to confirm that clamped voltage does not exceed downstream IC tolerances - the NUP4108W5T2G alone does not guarantee full interface safety.
Is the NUP4108W5T2G RoHS compliant and lead-free?
Yes, the NUP4108W5T2G is a Pb−free device and fully RoHS compliant, as confirmed in the official onsemi datasheet (Rev. 2, February 2007) and marked "Pb−Free" in the ordering information. It meets EU Directive 2011/65/EU and subsequent amendments, with lead content below 1000 ppm. The SC−88A package uses matte tin lead finish and is compatible with standard SnPb and lead-free reflow profiles up to 260°C peak temperature.
