Product details
Overview
PRTR5V0U2AX from Nexperia is an ultra-low-capacitance double rail-to-rail ESD protection diode in SOT143B package, designed to protect two high-speed data lines (e.g., USB 2.0 D+/D−) against IEC 61000-4-2 level 4 ESD transients (±12 kV), with 1.8 pF I/O-to-ground capacitance, 5.5 V reverse standoff voltage, and integrated VCC-to-GND clamping diode for supply-independent protection.
For engineers reviewing the PRTR5V0U2AX datasheet, PRTR5V0U2AX pinout, PRTR5V0U2AX application, or PRTR5V0U2AX equivalent, this device is selected for high-frequency signal integrity preservation in USB 2.0, HDMI, and DVI interfaces where sub-2 pF line capacitance and low clamping voltage are critical to maintain 480 Mbit/s data rates without distortion.
Technical Context
The PRTR5V0U2AX implements a triple-diode architecture: two rail-to-rail bidirectional ESD clamps between pins 2/3 and GND (pin 1), plus a dedicated unidirectional clamp from VCC (pin 4) to GND. This enables robust protection even when VCC is unpowered or floating.
Its 1.8 pF I/O-to-ground capacitance (measured at 1 MHz, 0 V bias) and 16 pF VCC-to-ground capacitance ensure minimal signal loading on differential high-speed lines, while the 6–9 V breakdown voltage and <100 nA reverse leakage at 3 V support stable DC biasing in active circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | IEC 61000-4-2 level 4: ±12 kV contact discharge - ensures compliance with industrial and consumer ESD immunity requirements without external components. |
| I/O-to-GND Capacitance | 1.8 pF (typ.) at 1 MHz, 0 V - preserves signal integrity for USB 2.0 (480 Mbit/s) and HDMI/DVI high-speed differential pairs. |
| Reverse Standoff Voltage | 5.5 V (max) - blocks normal operating voltages up to 5 V while triggering clamping during transients. |
| Breakdown Voltage | 6–9 V (min–max) - defines reliable turn-on threshold for ESD energy diversion before IC damage occurs. |
| Reverse Leakage Current | 1–100 nA at VR = 3 V - minimizes standby power loss and avoids interference with high-impedance receiver inputs. |
| VCC-to-GND Capacitance | 16 pF (typ.) - limits supply-line noise coupling without compromising transient response speed. |
Pinout & Package
SOT143B plastic surface-mount package: 4-lead, 1.9 mm pitch, 2.9 × 1.3 × 1.0 mm body, optimized for high-density PCB layouts near connectors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Common reference and transient return path; must be connected to low-inductance system ground plane. |
| 2 | I/O 1 | Protected high-speed signal line (e.g., USB D+); bidirectionally clamped to GND and VCC rails. |
| 3 | I/O 2 | Protected high-speed signal line (e.g., USB D−); independent rail-to-rail clamping identical to pin 2. |
| 4 | VCC | Supply connection enabling low-clamp-voltage operation; also provides VCC-to-GND ESD path when powered. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail bidirectional clamping | Enables protection of AC-coupled or DC-biased high-speed lines without polarity constraints or external biasing. |
| Integrated VCC-to-GND clamp | Ensures full ESD protection capability even when VCC is unpowered, eliminating reliance on system supply state. |
| 1.8 pF I/O capacitance | Meets USB 2.0 eye diagram mask requirements by minimizing intersymbol interference on 480 Mbit/s differential signals. |
| Small SOT143B footprint | Reduces PCB real estate and parasitic inductance - critical for maintaining clamping speed and impedance matching. |
Applications
| USB 2.0 Ports | Digital Video Interface (DVI) |
|---|---|
|
Use Scenario: Protecting D+/D− differential pair at upstream/downstream USB connectors against user-handling ESD events. IC Role / Device Role / Timing Role: Passive ESD transient suppressor placed immediately adjacent to connector, clamping fast-rising ±12 kV pulses within nanoseconds. Use Value: Maintains 480 Mbit/s data rate integrity by limiting I/O line capacitance to 1.8 pF and preventing signal overshoot/distortion during clamping. |
Use Scenario: Shielding TMDS clock and data channels in DVI source/sink devices from board-level ESD coupling. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp on each TMDS channel (clock, data0–2), referenced to local ground and VCC. Use Value: Prevents pixel corruption or link dropouts by ensuring clamping voltage stays below receiver absolute maximum ratings under ±12 kV stress. |
| HDMI Interfaces | Mobile Phone High-Speed Buses |
|
Use Scenario: Safeguarding HDMI 1.4a TMDS lanes on portable media players or display adapters exposed to frequent plug/unplug cycles. IC Role / Device Role / Timing Role: Rail-to-rail ESD protector on each of three data lanes and clock lane, mounted directly at HDMI receptacle. Use Value: Delivers sub-2 pF loading per lane to preserve rise/fall times required for 2.25 Gbit/s per lane operation. |
Use Scenario: Protecting MIPI D-PHY or eMMC data lines in smartphone mainboards from ESD during assembly, testing, or end-user handling. IC Role / Device Role / Timing Role: Dual-channel ESD suppressor for high-speed serial buses operating at 1–2 Gbit/s with tight timing margins. Use Value: Enables compact layout with minimal trace length between device and connector, reducing inductive ringing during ESD events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | Single-channel, 0.75 pF I/O capacitance, 5.5 V standoff, no VCC pin - uses internal capacitorless architecture. | Limited to one signal line; lacks VCC-referenced clamping, requiring external bias for optimal performance. | Select when ultra-low capacitance (<1 pF) is prioritized over dual-line integration and supply-independent operation. |
| ESD5V3U2MUTAG | Dual-channel, 2.5 pF I/O capacitance, 5.3 V standoff, includes VCC pin but higher leakage (500 nA). | Higher capacitance degrades margin for 480 Mbit/s USB 2.0; acceptable for lower-speed DVI/HDMI variants. | Choose when cost sensitivity outweighs strict 1.8 pF requirement and higher leakage is tolerable in non-battery systems. |
Compared with TPD2E001DRYR and ESD5V3U2MUTAG, PRTR5V0U2AX uniquely balances dual-channel integration, 1.8 pF capacitance, ±12 kV ESD rating, and VCC-enabled clamping - making it optimal for space-constrained, high-data-rate USB 2.0 and DVI designs requiring guaranteed protection without supply dependency.

FAQ
Is PRTR5V0U2AX suitable for USB 2.0 full-speed (12 Mbit/s) and high-speed (480 Mbit/s) operation?
Yes - its 1.8 pF I/O-to-ground capacitance and rail-to-rail clamping architecture are explicitly validated for USB 2.0 compliance, supporting both full-speed and high-speed modes without signal degradation or eye diagram violations. Layout proximity to the connector and short trace lengths are essential to maintain performance.
What is the role of the VCC pin (pin 4) when the system supply is absent?
Pin 4 provides a dedicated low-impedance path from VCC to GND via an integrated ESD diode, enabling effective clamping even when VCC is unpowered or floating. This ensures continuous protection for I/O lines regardless of system power state - a key differentiator versus passive-only ESD arrays.
Can PRTR5V0U2AX be used in AC-coupled differential signal paths?
Yes - its rail-to-rail bidirectional structure allows symmetric clamping above and below GND, making it compatible with AC-coupled lines like HDMI TMDS or USB 2.0 D+/D−. No DC bias is required, and the 5.5 V standoff voltage accommodates typical common-mode swing ranges.
Does PRTR5V0U2AX require external capacitors for optimal ESD performance?
No - the device achieves full IEC 61000-4-2 level 4 (±12 kV) protection without external capacitors. Its integrated VCC-to-GND diode eliminates the need for decoupling caps typically used to stabilize clamp behavior, simplifying layout and reducing BOM count.
