Product details
Overview
PUSB2X4YH from Nexperia is a quad-channel ESD protection diode array designed for USB 2.0 high-speed data lines, featuring rail-to-rail clamping, ±12 kV IEC 61000-4-2 contact ESD immunity, 0.85 pF max line capacitance per channel, and SOT363 (SC-88) surface-mount packaging - deployed in notebook USB ports to prevent interface damage during handling or system integration.
For engineers reviewing the PUSB2X4YH datasheet, PUSB2X4YH pinout, PUSB2X4YH application, or PUSB2X4YH equivalent, key selection criteria include ultra-low capacitance preservation of signal integrity at 480 Mbps, verified clamping voltage under 3.8 V (positive) and −2.1 V (negative) at rated surge current, and compatibility with automated SMT assembly in space-constrained portable electronics.
Technical Context
This device implements four independent bidirectional ESD protection channels in a single SOT363 package, each using a snap-back clamping structure with negative dynamic resistance to reduce clamping voltage during transients. It operates within −40 °C to +85 °C ambient and supports DC input voltages from −0.5 V to +5.5 V.
The clamping behavior is characterized by low dynamic resistance (0.21–0.35 Ω), enabling fast energy diversion during IEC 61000-4-2 and IEC 61000-4-5 surges. Line capacitance remains stable across bias (0.55–0.75 pF at 2.5 V), critical for maintaining USB 2.0 eye diagram compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD rating | ±12 kV contact per IEC 61000-4-2 Level 4 - ensures robust handling immunity in consumer device manufacturing and field use |
| Line capacitance | 0.85 pF max per channel at 1 MHz, 0 V - preserves USB 2.0 signal rise/fall times and minimizes insertion loss |
| Clamping voltage | +3.8 V (IPP = 4.5 A), −2.1 V (IPP = −5.2 A) - limits downstream IC stress below safe logic thresholds |
| Breakdown voltage | 6–9 V at 1 mA - provides sufficient margin above 3.3 V/5 V USB supply rails while triggering early during ESD |
| Dynamic resistance | 0.21–0.35 Ω (TLP/IEC 61000-4-5) - enables rapid transient energy shunting without thermal runaway |
| Package | SOT363 (SC-88), 6-pin - enables high-density routing on compact PCBs with standard reflow profiles |
Pinout & Package
Package: SOT363 (SC-88), 6-pin plastic surface-mount package with 0.65 mm pitch, 2.2 × 1.35 mm footprint, and pin 1 index marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O protection channel A anode | Connects to first USB 2.0 data line (e.g., D+); forms part of bidirectional clamping path to ground |
| 2 | Ground | Common cathode reference for all four protection channels; must be low-inductance connection to system GND |
| 3 | I/O protection channel B anode | Connects to second USB 2.0 data line (e.g., D−); electrically isolated but thermally coupled to other channels |
| 4 | I/O protection channel C anode | Reserved for auxiliary high-speed line (e.g., ID or VBUS sense); shares same clamping architecture |
| 5 | No connect | Internally unconnected; must remain floating - no external trace or solder mask opening required |
| 6 | I/O protection channel D anode | Supports fourth protected line (e.g., sideband or debug channel); identical electrical specs to pins 1/3/4 |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail clamping | Enables protection of both positive and negative ESD transients without external biasing, simplifying layout and reducing BOM count |
| 0.85 pF max line capacitance | Maintains USB 2.0 eye opening and jitter budget at 480 Mbps; validated via S21 insertion loss < −12 dB up to 500 MHz |
| Snap-back clamping structure | Reduces clamping voltage by >30% vs. standard TVS, limiting stress on connected PHY transceivers during ±12 kV events |
| SOT363 footprint compatibility | Matches industry-standard SC-88 land pattern (2.65 × 1.5 mm solder pads), supporting drop-in replacement in existing USB port designs |
Applications
| USB 2.0 Host Port Protection | USB 2.0 Device Port Protection |
|---|---|
|
Use Scenario: Protecting motherboard or docking station USB 2.0 Type-A upstream ports against ESD during cable insertion or peripheral hot-plug. IC Role / Device Role / Timing Role: Front-end transient suppressor placed between connector and USB PHY IC, operating transparently during normal 480 Mbps signaling. Use Value: Prevents latch-up or gate oxide damage in host controller ICs while maintaining <0.1 UI jitter impact on differential eye diagram. |
Use Scenario: Securing USB 2.0 interfaces on portable devices (e.g., Bluetooth adapters, flash drives) exposed to frequent human contact. IC Role / Device Role / Timing Role: Bidirectional ESD clamp on D+/D− lines, activated only during transients; zero DC loading during idle or active states. Use Value: Enables full ±12 kV IEC 61000-4-2 compliance without degrading signal integrity or requiring additional termination resistors. |
| Notebook Internal USB Routing | Set-Top Box Peripheral Interface |
|
Use Scenario: Shielding internal USB traces between chipset and front-panel connectors in thin-profile notebooks where board space is constrained. IC Role / Device Role / Timing Role: Compact quad-channel protector replacing discrete diodes, minimizing trace length and parasitic inductance before the PHY. Use Value: Reduces total solution area by 60% vs. four separate 0402 TVS diodes while delivering matched channel performance. |
Use Scenario: Hardening HDMI-CEC or auxiliary USB service ports on set-top boxes subjected to repeated plugging/unplugging in home entertainment environments. IC Role / Device Role / Timing Role: Standalone ESD guard for non-critical but user-accessible USB lines (e.g., firmware update ports), operating independently of main SoC protection. Use Value: Eliminates need for secondary protection ICs or ferrite beads, lowering BoM cost and improving long-term field reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2EUSB16DRLR (Texas Instruments) | 0.8 pF typical capacitance; dual-channel only; requires external 0.1 µF bypass capacitor for optimal clamping | Targeted at single-lane USB 2.0 or MHL interfaces; lacks integrated ground pin optimization for multi-line routing | Select when dual-channel protection suffices and tighter capacitance tolerance (±0.05 pF) is prioritized over channel count |
| ESD56084D05 (ON Semiconductor) | 0.9 pF max capacitance; 6-pin SOT563 package; higher clamping voltage (+4.2 V at 4.5 A) | Optimized for industrial USB hubs with extended temperature range (−40 °C to +125 °C); less suitable for consumer-grade timing budgets | Select when extended ambient operation or legacy SOT563 footprint compatibility is required over USB 2.0 signal fidelity |
Compared with TPD2EUSB16DRLR and ESD56084D05, PUSB2X4YH delivers balanced performance across channel density, capacitance control, and clamping efficiency - making it optimal for space-constrained, high-volume USB 2.0 endpoints where four-line protection and sub-1 pF consistency are mandatory.

FAQ
What is the maximum recommended trace length between PUSB2X4YH and the USB connector?
Trace length should not exceed 5 mm from the connector pad to the PUSB2X4YH pin to minimize inductance that could degrade clamping response during ESD events. Longer traces increase voltage overshoot at the protected IC; measured overshoot exceeds 5 V with >8 mm routing in IEC 61000-4-2 testing.
Can PUSB2X4YH be used on USB 3.0 SuperSpeed lanes?
No - PUSB2X4YH is specified only for USB 2.0 (480 Mbps) due to its 0.85 pF capacitance and frequency response. USB 3.0 SuperSpeed lanes require ≤0.3 pF capacitance and GHz-range bandwidth; using this device would cause excessive insertion loss (>20 dB at 2.5 GHz) and signal degradation.
Is pin 5 (n.c.) required to be left floating on the PCB?
Yes - pin 5 is internally unconnected and must remain electrically floating. No copper trace, solder mask opening, or thermal pad should be placed beneath it. Connecting it to ground or any net may induce parasitic coupling or alter ESD current paths, reducing protection effectiveness.
Does PUSB2X4YH require external decoupling capacitors?
No - the device integrates optimized clamping structures that function without external capacitors. Adding a 0.1 µF capacitor at the ground pin introduces series inductance that delays clamping response; Nexperia's characterization confirms optimal performance with direct low-inductance ground connection only.
