Nexperia USA Inc. PRTR5V0U2AX,215

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 contact). It features 1.8 pF I/O-to-ground capacitance, 5.5 V reverse standoff voltage, and integrates a dedicated V_CC-to-GND ESD diode for supply-independent clamping.

For engineers reviewing the PRTR5V0U2AX datasheet, PRTR5V0U2AX pinout, PRTR5V0U2AX application, or PRTR5V0U2AX equivalent, this device is selected specifically 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 mandatory to avoid signal distortion at 480 Mbit/s.

Technical Context

This dual-channel rail-to-rail ESD protector uses back-to-back diode pairs between each I/O pin and both V_CC and GND, enabling symmetrical clamping during positive and negative transients without requiring bias. The integrated V_CC-to-GND diode ensures protection remains active even when V_CC is unpowered or floating.

Its 1.8 pF I/O-to-GND capacitance (measured at 1 MHz, 0 V bias) and 16 pF V_CC-to-GND capacitance minimize signal loading on differential high-speed lines. Reverse leakage is limited to 100 nA at 3 V, supporting low-power system design while maintaining robust 6–9 V breakdown voltage.

FAQ

What is the maximum operating temperature range for PRTR5V0U2AX?

The PRTR5V0U2AX is rated for ambient temperatures from −40 °C to +125 °C and storage temperatures from −55 °C to +125 °C, per IEC 60134 limiting values. This range supports deployment in industrial, automotive-adjacent, and consumer environments where thermal cycling and sustained high-temperature operation occur.

Does PRTR5V0U2AX require external capacitors for ESD protection?

No external capacitors are required. The device achieves full IEC 61000-4-2 Level 4 ESD protection (±12 kV contact) using its internal rail-to-rail diode architecture and integrated V_CC-to-GND diode. Adding external capacitors would increase line capacitance and degrade high-speed signal integrity.

How does the V_CC pin function when left unconnected?

When V_CC is unconnected or at 0 V, the internal V_CC-to-GND ESD diode remains functional, enabling clamping between I/O pins and GND. This ensures full ESD protection capability even during power-down or hot-plug scenarios where supply is not yet established.

Can PRTR5V0U2AX be used on 1.8 V logic lines?

Yes. Its 5.5 V reverse standoff voltage and 6–9 V breakdown voltage provide ample margin above 1.8 V rail operation. The rail-to-rail architecture clamps transients relative to both V_CC and GND, making it compatible with 1.8 V, 3.3 V, and 5 V systems without redesign.
