Product details
Overview
PESD2USB3UV-TR from Nexperia is a dual-channel unidirectional automotive-grade ESD protection diode in SOT23 package, designed for high-speed data lines including USB 2.0, HDMI, and DisplayPort. It delivers 3.3 V reverse standoff voltage, 0.83 pF typical capacitance, 2.6 V clamping at 8 A, 18 kV IEC 61000-4-2 ESD immunity, and operates up to 175 °C junction temperature-enabling robust protection in infotainment bus interfaces.
For engineers reviewing the PESD2USB3UV-TR datasheet, PESD2USB3UV-TR pinout, PESD2USB3UV-TR application, or PESD2USB3UV-TR equivalent, key selection criteria include ultra-low capacitance for signal integrity, AEC-Q101 qualification for automotive reliability, common-anode dual-diode topology for differential line protection, and verified clamping performance under IEC/ISO transient standards.
Technical Context
This device implements a common-anode dual-diode architecture where pins 1 and 2 serve as independent cathodes and pin 3 is the shared anode-enabling bidirectional transient suppression across two signal lines referenced to a common ground plane. Its unidirectional configuration ensures low leakage (<50 nA at 3.3 V) and precise clamping onset above VRWM.
Designed specifically for high-speed serial buses, it maintains sub-1 pF capacitance (0.83 pF typ.) with <0.5% matching between channels, minimizing signal distortion on 480 Mbps USB 2.0 and multi-Gbps HDMI links. Dynamic resistance is specified at 0.14 Ω (typ.), ensuring rapid voltage clamping during 100 ns TLP pulses up to 16 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 3.3 V - Ensures no conduction during normal 3.3 V bus operation; defines maximum continuous working voltage. |
| Clamping Voltage | 2.6 V at 8 A (IEC 61000-4-5 8/20 µs) - Limits transient voltage seen by downstream PHY to safe levels below IC absolute maximum ratings. |
| Diode Capacitance | 0.83 pF at 1 MHz, 0 V - Preserves signal integrity on USB 2.0 and HDMI differential pairs without measurable insertion loss or timing skew. |
| ESD Withstand | 18 kV contact discharge (IEC 61000-4-2 & ISO 10605) - Meets stringent automotive infotainment ESD immunity requirements per OEM specifications. |
| Junction Temperature | 175 °C max - Supports placement near heat-generating SoCs or power stages in compact head-unit PCB layouts. |
| Leakage Current | 1 nA typ. at 3.3 V - Prevents DC loading of high-impedance receiver inputs and avoids false detection in hot-plug circuits. |
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 high-density routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Connects to first protected signal line (e.g., USB D+); conducts ESD current to common anode when voltage exceeds VRWM. |
| 2 | Cathode (Diode 2) | Connects to second protected signal line (e.g., USB D−); enables symmetrical protection of differential pairs without cross-talk. |
| 3 | Common Anode | Connected to system ground; serves as shared return path for both diodes-reducing PCB trace count and layout complexity. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance matching | ≤0.5% ∆Cd/Cd - Ensures balanced impedance and phase response across differential lanes, critical for HDMI 1.4 eye diagram compliance. |
| AEC-Q101 qualified | Qualified to Grade 3 (−40 °C to +125 °C ambient) - Validated for under-hood and dashboard-mounted infotainment modules per automotive reliability standards. |
| Low dynamic resistance | 0.14 Ω typ. - Minimizes voltage overshoot during fast-rising ESD events (e.g., 1 ns rise time), improving clamping fidelity. |
| High-temperature operation | 175 °C Tj max - Enables placement adjacent to thermal sources like video processors without derating or failure risk. |
Applications
| USB 2.0 Interface Protection | HDMI Data Lane Protection |
|---|---|
Use Scenario: ESD protection for USB 2.0 D+/D− lines in automotive head units and rear-seat entertainment systems. IC Role / Device Role / Timing Role: Unidirectional transient voltage suppressor placed directly at connector entry point to shunt ESD energy before reaching USB transceiver PHY. Use Value: 0.83 pF capacitance prevents signal degradation at 480 Mbps; 2.6 V clamping ensures PHY input stays within ±3.6 V absolute maximum rating. |
Use Scenario: Protection of TMDS clock and data channels in automotive HDMI displays and camera video links. IC Role / Device Role / Timing Role: Dual-channel clamp on differential pairs, leveraging matched capacitance to preserve differential impedance and minimize skew. Use Value: ≤0.5% capacitance mismatch maintains <1 ps inter-pair skew; 18 kV ESD rating meets OEM EMC test plans for infotainment subsystems. |
| DisplayPort Link Protection | GMSL SerDes Interface |
Use Scenario: High-speed serial link protection in digital instrument clusters using DisplayPort 1.2a (5.4 Gbps). IC Role / Device Role / Timing Role: Common-anode dual diode placed inline with main link lanes to suppress contact ESD without affecting AC-coupled signaling. Use Value: Sub-1 pF loading avoids violation of DP AC coupling capacitor impedance targets; 3.3 V VRWM aligns with DP receiver common-mode voltage range. |
Use Scenario: ESD hardening of GMSL (Gigabit Multimedia Serial Link) serializer/deserializer interfaces in ADAS camera modules. IC Role / Device Role / Timing Role: Front-end protection element on serialized video and control lines operating up to 3 Gbps with tight jitter budgets. Use Value: 0.14 Ω dynamic resistance limits transient-induced jitter; 175 °C Tj rating supports placement in sealed camera housings exposed to solar loading. |
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 (12 pF), lower ESD rating (15 kV), same SOT23-3 package | Targeted at industrial USB/HDMI, not AEC-Q101 qualified | Select only for non-automotive designs where cost outweighs signal integrity and qualification requirements. |
| Vishay VEML3010-001 | Unidirectional dual-diode, 0.9 pF, 15 kV ESD, AEC-Q101 Grade 2 (−40 °C to +105 °C) | Limited to 105 °C ambient; lacks 175 °C junction rating for under-dash deployment | Acceptable for center-console modules but not for engine-bay-adjacent head units requiring full Grade 3 thermal margin. |
Compared with NUP4201MR6T1G and VEML3010-001, PESD2USB3UV-TR uniquely combines automotive-grade thermal capability (175 °C Tj), ultra-low capacitance (0.83 pF), and full 18 kV ESD immunity-making it the only option qualified for next-generation high-bandwidth, thermally constrained automotive multimedia interfaces.

FAQ
Is PESD2USB3UV-TR compatible with USB 3.0 or higher-speed interfaces?
No-PESD2USB3UV-TR is characterized for USB 2.0 (480 Mbps) and HDMI 1.4 (3.4 Gbps) applications. Its 0.83 pF capacitance and clamping behavior are validated up to ~3.5 GHz; USB 3.0 SuperSpeed (5 Gbps) requires lower capacitance (<0.3 pF) and different topology, such as array-based or integrated TVS solutions with enhanced RF performance.
Can pin 3 (common anode) be left floating or tied to a voltage other than ground?
No-pin 3 must be connected directly to a low-inductance system ground plane. Floating the anode disables ESD protection; connecting it to any voltage above ground violates the unidirectional diode's bias condition and may cause permanent damage or unpredictable clamping behavior during transients.
What is the meaning of "Cd matching" and why does it matter for differential signals?
"Cd matching" refers to the capacitance difference between pin 1–3 and pin 2–3, specified as ≤0.5%. For differential buses like HDMI or DisplayPort, mismatched capacitance introduces skew and common-mode imbalance, degrading eye height/width and increasing bit error rate-especially at multi-Gbps data rates where timing margins are sub-100 ps.
Does PESD2USB3UV-TR protect against electrical fast transients (EFT) per IEC 61000-4-4?
Yes-the device's 8 A rated peak pulse current (IPPM) and 2.6 V clamping voltage are tested per IEC 61000-4-5 (surge), and its low dynamic resistance (0.14 Ω) and fast response enable effective suppression of 5 kHz burst EFT waveforms. However, system-level EFT compliance requires proper PCB layout, grounding, and filtering in addition to device-level protection.
