Product details

Overview

PRTR5V0U2AX-QR 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 ±12 kV IEC 61000-4-2 level 4 ESD transients while maintaining signal integrity via 1.8 pF I/O-to-ground capacitance and 5.5 V reverse standoff voltage.

For engineers reviewing the PRTR5V0U2AX-QR datasheet, PRTR5V0U2AX-QR pinout, PRTR5V0U2AX-QR application, or PRTR5V0U2AX-QR equivalent, this device is selected for high-frequency interface protection where sub-2 pF line loading, automotive-grade AEC-Q101 qualification, and supply-independent clamping are critical design requirements.

Technical Context

This dual-channel ESD protector integrates two rail-to-rail diodes between each I/O pin and both supply (VCC) and ground (GND), plus a dedicated GND–VCC clamp diode to prevent supply-line charging during ESD events. It operates without bias-clamping remains effective even at 0 V supply.

The architecture delivers symmetrical bidirectional protection with low dynamic impedance, enabling fast transient response (<30 ns rise time per IEC 61000-4-2) and minimal signal distortion on data lines up to 480 Mbit/s. Its 1.8 pF capacitance is measured at 1 MHz, 0 V bias, 25 °C across pins 2 and 3 to GND.

Key Specifications

Parameter Value and Actual Design Meaning
ESD Rating ±12 kV per IEC 61000-4-2 level 4 - ensures robust immunity against human-body-model ESD events at connector interfaces.
I/O-to-GND Capacitance 1.8 pF (typ.) - preserves signal integrity on USB 2.0, HDMI, and DVI lines by minimizing high-frequency attenuation and timing skew.
Reverse Standoff Voltage 5.5 V - blocks normal operating voltages up to 5 V systems while remaining transparent during signal transmission.
Breakdown Voltage 6–9 V (typ.) - defines the onset of clamping conduction, ensuring safe margin above 5.5 V VRWM for reliable turn-on during transients.
Reverse Leakage Current 1 nA (typ.) at 3 V - minimizes DC loading on high-impedance signal paths and preserves power budget in battery-powered devices.
Ambient Temperature Range −40 °C to +125 °C - supports operation in under-hood automotive environments and industrial edge nodes.

Pinout & Package

SOT143B plastic surface-mounted package: 4-lead, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body height. RoHS-compliant, qualified per AEC-Q101.

Pin/Terminal Circuit Role Design Meaning
1 GND Primary reference node for all clamping paths; must be connected to low-inductance system ground plane.
2 I/O 1 Protected signal line 1 (e.g., USB D+); bidirectionally clamped to GND and VCC via internal rail-to-rail diodes.
3 I/O 2 Protected signal line 2 (e.g., USB D−); independently clamped with identical characteristics as Pin 2.
4 VCC Supply connection for active clamping path; enables low-VF forward conduction when transient exceeds VRWM.

Key Features

Feature Design Value
Rail-to-rail clamping architecture Enables symmetric ±V transient suppression on both I/O lines without polarity dependence or external biasing.
Integrated GND–VCC ESD diode Prevents VCC line charging during negative transients, eliminating need for external decoupling capacitors in clamping path.
AEC-Q101 qualification Validated for automotive use including temperature cycling, HTRB, and ESD stress-supports Tier-1 module designs.
1.8 pF I/O capacitance Meets USB 2.0 eye-diagram mask requirements at 480 Mbit/s; avoids intersymbol interference in high-speed serial links.
No supply dependency for basic protection Clamps transients even with VCC = 0 V, ensuring fail-safe protection during power-down or brownout conditions.

Applications

USB 2.0 Interface Protection HDMI/DVI Signal Line Protection

Use Scenario: Protecting D+ and D− differential pair at USB 2.0 Type-A or Micro-B connectors against ESD during hot-plug events.

IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at connector, providing sub-30 ns clamping response.

Use Value: Maintains 480 Mbit/s data rate compliance by limiting I/O capacitance to 1.8 pF and avoiding signal reflection or jitter accumulation.

Use Scenario: Shielding TMDS clock and data channels in HDMI 1.4 or DVI-D interfaces from contact ESD during cable insertion.

IC Role / Device Role / Timing Role: Low-capacitance shunt protector positioned before EMI filters and common-mode chokes to preserve high-frequency signal fidelity.

Use Value: Enables >165 MHz pixel clock support with <0.1 UI jitter impact due to ultra-low 1.8 pF line loading and matched channel capacitance.

Automotive Infotainment Port Protection Mobile Device High-Speed Interface Protection

Use Scenario: Safeguarding USB-C or micro-USB ports in head units and display modules exposed to harsh vehicle cabin ESD environments.

IC Role / Device Role / Timing Role: AEC-Q101-qualified ESD array providing fail-safe clamping independent of system power state.

Use Value: Ensures uninterrupted media streaming and firmware updates by surviving repeated ±12 kV contact discharges per ISO 10605.

Use Scenario: Protecting MIPI D-PHY lanes (e.g., camera sensor interfaces) in smartphones and tablets where board space and capacitance budgets are constrained.

IC Role / Device Role / Timing Role: Dual-channel ESD suppressor integrated into compact camera module flex circuits near image sensor connectors.

Use Value: Delivers 1.8 pF loading per lane and −40 °C to +125 °C operation, enabling reliable 1.5 Gbps D-PHY signaling in thermally aggressive enclosures.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-channel rail-to-rail ESD protection applications.

Alternative Part Technical Difference Application Difference Selection Advice
ON Semiconductor NUP4201MR6T1G Higher 3.5 pF I/O capacitance; single-package quad-channel (not dual); no integrated VCC–GND diode. Limited to lower-speed interfaces (<100 Mbit/s); requires external VCC decoupling for optimal clamping. Select when cost sensitivity outweighs speed requirements and layout allows larger footprint.
Vishay VEML6030X01 Optical sensor IC-not an ESD protector; functionally incompatible. Not applicable-misidentified part; excluded from ESD protection selection. Avoid: not a functional alternative; VEML6030X01 is ambient light sensor, not ESD diode.

Compared with NUP4201MR6T1G, PRTR5V0U2AX-QR provides 2.0× lower capacitance and integrated supply-clamp functionality-critical for USB 2.0 and automotive infotainment. VEML6030X01 is not an ESD protection device and must be excluded from consideration.

FAQ

Is PRTR5V0U2AX-QR compatible with USB 2.0 full-speed and high-speed signaling?

Yes. With 1.8 pF I/O-to-ground capacitance and <30 ns clamping response per IEC 61000-4-2, it meets USB-IF eye diagram requirements for 480 Mbit/s high-speed operation. Layout best practices-such as placing the device within 3 mm of the connector and using short, direct traces to GND-must be followed to maintain signal integrity.

Does PRTR5V0U2AX-QR require external capacitors for ESD protection?

No. The integrated GND–VCC ESD diode eliminates the need for external decoupling capacitors on the VCC line. This simplifies PCB layout, reduces BOM count, and avoids resonance risks introduced by discrete capacitor parasitics-verified in Nexperia's application note AN11167.

What is the maximum operating voltage for continuous DC bias on the I/O pins?

The reverse standoff voltage (VRWM) is rated at 5.5 V, meaning the device remains non-conductive under steady-state DC bias up to 5.5 V. It is intended for 3.3 V and 5 V systems; operation above 5.5 V risks premature breakdown and permanent damage per absolute maximum ratings.

How does PRTR5V0U2AX-QR perform under zero-supply conditions?

It maintains full ESD protection capability with VCC = 0 V. The rail-to-rail diodes clamp between I/O pins and GND, while the integrated GND–VCC diode remains reverse-biased but does not impede protection. Clamping voltage rises slightly versus powered operation, yet still limits transients to safe levels per IEC 61000-4-2 testing.
