Product details
Overview
PESD2USB5UV-TR from Nexperia is a dual-channel unidirectional automotive ESD protection diode in SOT23 package, designed to safeguard high-speed USB 2.0 and HDMI data lines against ±22 kV IEC 61000-4-2 and ISO 10605 transients. It delivers 5 V reverse standoff voltage, 0.76 pF typical capacitance, and clamps at 2.4 V under 8 A TLP pulse - enabling signal integrity preservation in infotainment serial buses.
For engineers reviewing the PESD2USB5UV-TR datasheet, PESD2USB5UV-TR pinout, PESD2USB5UV-TR application, or PESD2USB5UV-TR equivalent, this device is selected for AEC-Q101-compliant ESD hardening of differential high-speed interfaces where sub-1 pF capacitance and low clamping voltage are critical to maintain eye diagram margin and bit error rate performance.
Technical Context
This device implements two independent unidirectional ESD protection diodes sharing a common anode (Pin 3), configured for bidirectional transient suppression across two signal lines (Pins 1 and 2). Its architecture targets low-capacitance coupling to preserve signal rise/fall times on USB 2.0 (480 Mbps) and HDMI TMDS channels.
Clamping behavior is characterized by dynamic resistance of 0.12 Ω at 10 A and stable 2.4 V clamping at 8 A TLP, with junction temperature rated up to 175 °C for under-hood deployment. It meets AEC-Q101 Grade 0/1/3 stress requirements and supports operation from −55 °C to +175 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Ensures no leakage or conduction during normal 5 V USB/HDMI signal swing. |
| Clamping Voltage | 2.4 V at 8 A TLP - Limits voltage excursion below IC I/O absolute maximum rating during ESD event. |
| Diode Capacitance | 0.76 pF at 1 MHz - Minimizes signal distortion and insertion loss on >480 Mbps USB 2.0 links. |
| ESD Withstand | ±22 kV per IEC 61000-4-2 contact discharge - Meets automotive infotainment system-level ESD immunity requirements. |
| Junction Temperature | 175 °C - Supports placement near heat sources in head unit or display module PCBs. |
| Peak Pulse Current | 10 A per IEC 61000-4-5 8/20 µs - Handles surge events from load dump or inductive switching in vehicle power domains. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 × 1.3 × 1.0 mm body. Optimized for automated reflow assembly and space-constrained automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Connects to first protected line (e.g., USB D+); conducts transient current to common anode during negative ESD event. |
| 2 | K2 (Cathode 2) | Connects to second protected line (e.g., USB D−); enables independent protection of differential pair without cross-talk. |
| 3 | CA (Common Anode) | Connected to ground plane; serves as shared return path for both diodes' clamping current during ESD strike. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance matching | ΔCd/Cd ≤ 0.5 % - Ensures balanced impedance and common-mode rejection on differential buses like LVDS and USB. |
| Automotive qualification | AEC-Q101 compliant - Validated for temperature cycling, HTRB, and ESD robustness required in Tier-1 automotive supply chain. |
| Low dynamic resistance | 0.12 Ω at 10 A - Reduces voltage overshoot during fast-rising ESD pulses (<1 ns rise time). |
| High-temperature operation | 175 °C max junction temperature - Enables use in proximity to power management ICs or display drivers in compact modules. |
Applications
| USB 2.0 Interface Protection | HDMI TMDS Channel Protection |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4201MR6T1G | Higher capacitance (1.2 pF), lower ESD rating (±15 kV IEC 61000-4-2), same SOT23-3 package. | Approved for non-critical industrial USB ports; not AEC-Q101 qualified. | Select only for cost-sensitive non-automotive designs where 0.44 pF higher capacitance is acceptable. |
| Vishay ESDE05V55D04 | Quad-channel configuration (4-line protection), 0.6 pF capacitance, ±25 kV ESD rating, SOT363 package. | Requires PCB redesign due to 6-pin footprint and different pin assignment; supports HDMI + USB dual-interface protection in one device. | Choose when consolidating protection for multi-interface modules and board space permits SOT363 layout. |
Compared with NUP4201MR6T1G and ESDE05V55D04, PESD2USB5UV-TR uniquely balances AEC-Q101 compliance, 0.76 pF capacitance, and dual-channel SOT23 integration - making it optimal for space-constrained, high-reliability automotive USB/HDMI nodes where qualification and signal fidelity are jointly mandated.

FAQ
Is PESD2USB5UV-TR compatible with USB 2.0 full-speed and high-speed signaling?
Yes. With 0.76 pF typical capacitance and <2.4 V clamping at 8 A, it preserves signal integrity for USB 2.0 high-speed (480 Mbps) operation. Measured insertion loss remains below 0.8 dB at 240 MHz, ensuring eye diagram compliance per USB-IF specifications without requiring equalization.
What is the grounding requirement for effective ESD clamping performance?
Pin 3 (common anode) must connect to a low-inductance chassis or system ground plane using short, wide traces (<5 mm length, ≥0.3 mm width). Ground path inductance directly impacts clamping voltage rise; values >2 nH degrade VCL by >15 % at 1 A/ns dI/dt.
Does PESD2USB5UV-TR support bidirectional signal lines like HDMI TMDS?
Yes - its dual unidirectional topology (K1–CA and K2–CA) provides symmetrical clamping for both polarities on each line. When paired across differential pairs (e.g., TMDS+ and TMDS−), it delivers balanced ±22 kV protection without degrading common-mode rejection ratio.
How does its AEC-Q101 qualification differ from standard industrial ESD diodes?
It undergoes accelerated stress testing including 1000-cycle temperature cycling (−55 °C to +175 °C), 1000-hour high-temperature reverse bias, and human-body-model ESD validation at extreme temperatures - all beyond JEDEC JESD22 standards and required for Tier-1 automotive procurement.
