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 ±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 datasheet, PRTR5V0U2AX pinout, PRTR5V0U2AX application, or PRTR5V0U2AX equivalent, this device is selected for high-frequency signal line protection where minimal capacitive loading, low clamping voltage, and supply-independent operation are critical - especially in USB 2.0, HDMI, and mobile interface designs.
Technical Context
The PRTR5V0U2AX integrates three ESD protection diodes: two rail-to-rail diodes (pins 2–1 and 3–1) for bidirectional I/O protection, and a third diode (pin 4–1) between VCC and GND to clamp supply-line transients and prevent VCC charging during ESD events - enabling protection even with no applied supply voltage.
Its architecture delivers 1.8 pF I/O-to-ground capacitance at 1 MHz and 0 V bias, 16 pF supply-to-ground capacitance, and a typical breakdown voltage of 7.5 V, ensuring fast response (<1 ns rise time) and low clamping under ±8 kV IEC 61000-4-2 pulses without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5.5 V - Maximum continuous operating voltage before conduction begins; ensures compatibility with 5 V USB 2.0 and HDMI signal rails. |
| I/O-to-GND Capacitance | 1.8 pF - Measured at 1 MHz, 0 V bias; preserves signal integrity up to 480 Mbit/s (USB 2.0 full-speed data rates). |
| VCC-to-GND Capacitance | 16 pF - Enables stable supply decoupling without requiring additional bulk capacitors in compact layouts. |
| ESD Withstand Level | ±12 kV - Complies with IEC 61000-4-2 level 4 contact discharge; protects against human-body-model transients in handheld and peripheral devices. |
| Breakdown Voltage | 6–9 V (typ. 7.5 V) - Defines clamping onset threshold; ensures robust transient suppression before downstream IC damage occurs. |
| Reverse Leakage Current | 1 nA (typ.) at 3 V - Minimizes standby power loss and avoids signal distortion in high-impedance receiver inputs. |
Pinout & Package
SOT143B plastic surface-mount package: 4-lead, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body height; optimized for high-density PCB layouts and reflow/wave soldering per JEDEC MS-012 standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Common reference node for all ESD clamping paths; must be connected to low-inductance system ground plane. |
| 2 | I/O 1 | Protected high-speed signal line (e.g., USB D+); rail-to-rail diode path to GND and VCC enables bidirectional clamping. |
| 3 | I/O 2 | Second protected high-speed signal line (e.g., USB D−); electrically isolated from I/O 1 but shares GND and VCC terminals. |
| 4 | VCC | Supply connection for active clamping; internal diode to GND prevents VCC overvoltage during ESD events, enabling protection without external supply. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail dual-channel protection | Two independent I/O paths each with symmetrical forward/reverse conduction to GND and VCC - eliminates need for separate positive/negative clamping networks. |
| Supply-independent ESD clamping | Integrated VCC-to-GND diode ensures protection remains active even when VCC is unpowered or floating - critical for hot-plug interfaces. |
| Ultra-low 1.8 pF I/O capacitance | Preserves signal edge rate and eye diagram integrity in 480 Mbit/s USB 2.0 links; avoids intersymbol interference and timing jitter. |
| IEC 61000-4-2 level 4 compliance | Validated for ±12 kV contact discharge - meets industrial and consumer end-equipment immunity requirements without derating. |
| Small-footprint SOT143B package | Enables placement within 2 mm of USB/HDMI connectors - minimizes transient loop area and improves PCB-level ESD suppression efficiency. |
Applications
| USB 2.0 Interface Protection | HDMI Signal Line Protection |
|---|---|
|
Use Scenario: Protecting D+ and D− differential pairs on host/device USB 2.0 ports against ESD during cable insertion or handling. IC Role / Device Role / Timing Role: Bidirectional ESD clamp placed immediately adjacent to the USB connector; provides sub-nanosecond response to ±8 kV transients. Use Value: Maintains 480 Mbit/s data throughput by limiting I/O capacitance to 1.8 pF - avoids signal rise-time degradation and bit-error-rate increase. |
Use Scenario: Shielding TMDS clock and data channels in HDMI 1.4 receivers/transmitters from ESD-induced latch-up or oxide damage. IC Role / Device Role / Timing Role: Rail-to-rail ESD suppressor on each TMDS pair; operates without VCC dependency to protect powered-down sinks. Use Value: Enables compliance with IEC 61000-4-2 level 4 while preserving >165 MHz pixel clock integrity through ultra-low 1.8 pF loading. |
| Mobile Phone High-Speed Bus Protection | LAN/WAN PHY Interface Protection |
|
Use Scenario: Safeguarding MIPI D-PHY or eMMC data lanes in smartphones against ESD during SIM/microSD card insertion or button actuation. IC Role / Device Role / Timing Role: Dual-channel ESD suppressor with shared GND/VCC; placed directly at board edge connectors to minimize trace inductance. Use Value: Prevents false touch interrupts or storage corruption by clamping transients below 5.5 V standoff - matching common mobile rail voltages. |
Use Scenario: Protecting Ethernet PHY differential pairs (e.g., 10/100BASE-TX) from ESD entering via RJ-45 magnetics or chassis ports. IC Role / Device Role / Timing Role: Low-capacitance ESD clamp on TX+/TX− and RX+/RX− lines; supports auto-negotiation signaling integrity. Use Value: Delivers 12 kV ESD immunity without degrading return loss or near-end crosstalk - verified for IEEE 802.3 compliance. |
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, 1.2 pF I/O capacitance, 5.5 V standoff, no VCC terminal - uses GND-only clamping architecture. | Lacks supply-rail protection; requires separate VCC decoupling; limited to single-line protection per device. | Choose when protecting isolated single-ended lines with tighter capacitance budget (<1.2 pF), but not for dual-rail or supply-clamping needs. |
| ESD5V3U2M | Double rail-to-rail, 2.5 pF I/O capacitance, 5.3 V standoff, integrated 15 pF VCC-to-GND capacitor - higher capacitance than PRTR5V0U2AX. | Higher I/O loading limits use in >240 Mbit/s applications; integrated VCC cap reduces layout flexibility. | Prefer for cost-sensitive designs where 2.5 pF is acceptable and built-in supply capacitance simplifies BOM. |
Compared with TPD2E001DRYR and ESD5V3U2M, PRTR5V0U2AX uniquely balances dual-channel rail-to-rail clamping, 1.8 pF I/O loading, and active VCC-to-GND protection - making it optimal for space-constrained USB 2.0 and HDMI interfaces requiring guaranteed ±12 kV immunity without signal degradation.

FAQ
Is PRTR5V0U2AX suitable for USB 3.0 or higher-speed interfaces?
No. Its 1.8 pF I/O capacitance and specified performance are validated only for up to 480 Mbit/s (USB 2.0). USB 3.0 SuperSpeed (5 Gbit/s) requires sub-0.5 pF capacitance and different clamping dynamics - use dedicated USB 3.0 ESD arrays like PUSB3FR4 instead.
Can PRTR5V0U2AX operate without a VCC connection?
Yes. The internal VCC-to-GND diode allows full ESD protection functionality even when VCC is unconnected or at 0 V. However, connecting VCC improves clamping performance for transients coupling onto the supply rail and stabilizes leakage behavior.
What is the maximum recommended PCB trace length between PRTR5V0U2AX and the protected connector?
Trace length should not exceed 2 mm from device to connector pad. Longer traces add inductance that degrades high-frequency ESD suppression; the device must be placed adjacent to the I/O entry point to maintain effective transient shunting to GND.
Does PRTR5V0U2AX require external TVS diodes or RC filters for full system-level ESD compliance?
No. It meets IEC 61000-4-2 level 4 alone when correctly laid out (short traces, solid ground plane). External components are unnecessary and may degrade signal integrity - the integrated triple-diode architecture is designed for standalone protection in USB 2.0 and HDMI applications.
