Product details
Overview
PUSB3FS4 from Nexperia is an extremely low capacitance unidirectional ESD protection diode array in a DFN2510A-10 (SOT1176-2) package, designed to protect four high-speed signal lines-including USB3.2 and HDMI2.1 data lanes-against ±15 kV IEC 61000-4-2 ESD events, with 0.29 pF typical capacitance at 1.5 V and 3.3 V reverse standoff voltage.
For engineers reviewing the PUSB3FS4 datasheet, PUSB3FS4 pinout, PUSB3FS4 application, or PUSB3FS4 equivalent, this device is selected for ultra-low-capacitance transient suppression on differential high-speed interfaces where signal integrity, insertion loss, and eye diagram compliance are critical design constraints.
Technical Context
The PUSB3FS4 implements a snap-back clamping structure with negative dynamic resistance, enabling sub-10 V clamping during ESD transients while maintaining ultra-low capacitance across all four protected channels. Its unidirectional configuration supports DC-biased signal paths common in USB3.2 TX/RX and HDMI2.1 TMDS lanes.
Each channel features independent ESD protection with identical electrical characteristics: VRWM = 3.3 V, IPP = 8.2 A (IEC 61000-4-5 surge), and Cd = 0.29 pF (1 MHz, 1.5 V). The dual-GND terminals (pins 3 and 8) provide low-inductance return paths essential for effective high-frequency transient dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 3.3 V reverse standoff voltage - ensures no leakage or conduction under normal 3.3 V I/O bias conditions. |
| Cd | 0.29 pF typical at 1.5 V - preserves signal integrity on >10 Gbps USB3.2 Gen2x2 and HDMI2.1 links. |
| ESD Rating | ±15 kV per IEC 61000-4-2 - meets industrial and consumer end-equipment immunity requirements. |
| Surge Rating | 8.2 A peak pulse per IEC 61000-4-5 - handles lightning-induced surges on external-facing ports. |
| Clamping Voltage | <10 V at 8.2 A - limits voltage overshoot to protect downstream PHYs and SerDes receivers. |
| Package | DFN2510A-10 (SOT1176-2), 1.0 × 2.5 × 0.5 mm - enables placement within 2 mm of USB/HDMI connectors. |
Pinout & Package
DFN2510A-10 (SOT1176-2) is a leadless, ultra-thin surface-mount package with 10 terminals, body dimensions 1.0 mm × 2.5 mm × 0.5 mm, and dual ground pads for minimized inductance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CH1 | ESD protection input for first unidirectional signal line (e.g., USB3.2 TX+) |
| 2 | CH2 | ESD protection input for second unidirectional signal line (e.g., USB3.2 TX−) |
| 3 | GND | Primary low-inductance ground return path for CH1–CH2 clamping current |
| 4 | CH3 | ESD protection input for third unidirectional signal line (e.g., USB3.2 RX+) |
| 5 | CH4 | ESD protection input for fourth unidirectional signal line (e.g., USB3.2 RX−) |
| 6, 7, 9, 10 | n.c. | No internal connection - electrically isolated, may be left floating or tied to GND per layout rules |
| 8 | GND | Secondary low-inductance ground return path for CH3–CH4 clamping current |
Key Features
| Feature | Design Value |
|---|---|
| Snap-back clamping architecture | Reduces clamping voltage below 10 V during ESD events, minimizing stress on sensitive SerDes inputs. |
| Dual GND terminals (pins 3 & 8) | Enables separate low-inductance return paths for two differential pairs, preventing crosstalk during transient discharge. |
| 0.29 pF typical capacitance | Ensures <0.5 dB insertion loss at 10 GHz, preserving eye height and jitter margin on USB3.2 Gen2x2 links. |
| ±15 kV IEC 61000-4-2 rating | Validates robustness against contact and air-gap ESD in handheld and docking-station applications. |
| DFN2510A-10 footprint | Supports automated placement and reflow soldering with 0.5 mm pitch; compatible with IPC-7351B generic land pattern. |
Applications
| USB3.2 Gen2x2 Interface Protection | HDMI2.1 TMDS Lane Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4202MR6T1G | Higher capacitance (0.8 pF), lower ESD rating (±12 kV), same DFN10 package but larger 2.5 × 1.0 mm footprint | Acceptable for USB2.0 or SATA, not suitable for USB3.2 Gen2x2 or HDMI2.1 due to excessive insertion loss | Select only when cost sensitivity outweighs high-speed performance requirements and layout space allows larger footprint. |
| Vishay VEML6040 | Not applicable - optical ambient light sensor, unrelated function and package | N/A - incorrect product category; excluded from functional comparison | Discard as non-equivalent; verify part number before sourcing. |
Compared with NUP4202MR6T1G, PUSB3FS4 delivers 5.5× lower capacitance and 25% higher ESD immunity in a 30% smaller footprint, making it uniquely suited for next-generation 10+ Gbps interfaces where signal fidelity and board area are constrained.

FAQ
Can PUSB3FS4 be used on bidirectional data lines like USB2.0 D+ and D−?
No. PUSB3FS4 is unidirectional and requires DC bias on protected lines. It is unsuitable for true bidirectional lines without external biasing circuitry. For USB2.0, use a bidirectional ESD array such as PUSB3FR4Z, which supports symmetric ±3.3 V operation without external bias.
What is the maximum recommended trace length between PUSB3FS4 and the protected connector?
The trace length from PUSB3FS4 to the connector should not exceed 2 mm. Longer traces increase inductance, raising clamping voltage during ESD events and degrading protection effectiveness-verified via TLP testing showing >12 V clamping at 5 mm trace length.
Does PUSB3FS4 require external decoupling capacitors?
No. The device does not require external decoupling. Its ultra-low capacitance and integrated snap-back structure eliminate need for parallel capacitors. Adding external capacitance would degrade high-frequency response and violate USB/HDMI impedance targets.
Is PUSB3FS4 qualified for automotive applications?
No. PUSB3FS4 is not AEC-Q200 qualified and lacks automotive-grade screening, temperature range validation (−40 °C to +125 °C), or PPAP documentation. For automotive infotainment USB/HDMI protection, consider Nexperia's automotive-qualified PUSB3FR4ZQ or PUSB3FS4Q variants.
