Product details
Overview
D3V3X4U10LPQ from Diodes Incorporated is a 4-channel ultra-low-capacitance TVS diode array designed for ESD protection of high-speed I/O lines, featuring 0.45 pF typical channel capacitance, 5.5 V minimum breakdown voltage, and 3 A peak pulse current (8/20 µs), deployed in USB 3.0, USB 3.1, and DisplayPort interfaces.
For engineers reviewing the D3V3X4U10LPQ datasheet, D3V3X4U10LPQ pinout, D3V3X4U10LPQ application, or D3V3X4U10LPQ equivalent, key selection criteria include clamping voltage at 16 A (6 V), IEC 61000-4-2 ±8 kV contact/air ESD rating, TLP dynamic resistance (0.3 Ω), and U-DFN2510-10 package compatibility with high-density PCB layouts.
Technical Context
This device implements four independent bidirectional TVS diodes between I/O pins and VSS, each optimized for sub-1 pF signal path loading while maintaining robust transient suppression. Its low dynamic resistance (0.3 Ω reverse, 0.2 Ω forward) ensures minimal voltage overshoot during fast ESD events.
The architecture supports simultaneous protection of four differential or single-ended high-speed data lanes without signal integrity degradation. It operates within -55°C to +150°C and meets AEC-Q101 qualification for automotive-grade reliability under IATF 16949 manufacturing control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Working Voltage | 3.3 V - Maximum continuous DC voltage applied across I/O–VSS without leakage exceeding 1.0 µA |
| Breakdown Voltage (VBR) | 5.5 V min - Voltage at which each channel begins avalanche conduction at 1 mA, ensuring reliable turn-on before system damage |
| Clamping Voltage (VC) | 6 V @ 16 A TLP - Peak voltage seen by protected line during worst-case ESD event, limiting stress on downstream ICs |
| Channel Input Capacitance | 0.45 pF typ - Enables use in >5 Gbps serial links (e.g., USB 3.1 Gen 1) without measurable signal rise-time degradation |
| ESD Rating (IEC 61000-4-2) | ±8 kV contact / ±8 kV air - Full compliance with industrial and automotive ESD immunity requirements |
| Peak Pulse Current (IPP) | 3 A @ 8/20 µs - Sustains lightning-surge transients per IEC 61000-4-5 without parametric shift or failure |
Pinout & Package
Package: U-DFN2510-10 - 2.5 mm × 1.0 mm × 0.575 mm body, 10-terminal leadless plastic package with NiPdAu-plated copper leadframe, moisture sensitivity level 1, UL 94V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5 | I/O Channel Terminal | Four independent protected signal paths; each connects to one high-speed data line (e.g., USB D+/D−, DP+/DP−) |
| 3, 8 | VSS (Ground) | Common cathode connection point for all four TVS diodes; must be tied to low-impedance system ground plane |
| 6, 7, 9, 10 | No Connection | Unbonded terminals; electrically isolated and not to be connected to any net to avoid parasitic coupling or solder wicking issues |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low input capacitance | 0.45 pF typical per channel - preserves signal integrity in 5+ Gbps differential interfaces without equalization overhead |
| Low clamping voltage | 6 V @ 16 A TLP - limits voltage excursion below 3.3 V rail tolerance thresholds of modern SerDes PHYs |
| Low dynamic resistance | 0.3 Ω reverse TLP resistance - reduces clamping voltage overshoot and improves energy dissipation efficiency |
| AEC-Q101 qualified | Qualified for automotive applications with PPAP capability and IATF 16949 manufacturing - enables use in ADAS camera links and infotainment USB ports |
Applications
| USB 3.0/3.1 Interface Protection | DisplayPort Line Protection |
|---|---|
Use Scenario: Protecting SuperSpeed TX/RX differential pairs in host/device connectors against ESD events during hot-plug insertion. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at connector entry point, shunting ESD current to chassis ground before reaching USB controller PHY. Use Value: 0.45 pF capacitance avoids eye diagram closure; 6 V clamping prevents PHY latch-up or oxide damage during ±8 kV contact discharge. | Use Scenario: Safeguarding DisplayPort main link lanes (up to HBR3) from electrostatic discharge in docking stations and monitors. IC Role / Device Role / Timing Role: Four-channel TVS array placed per-lane at receptacle side, with VSS tied to shield ground to minimize common-mode noise injection. Use Value: Sub-1 pF loading maintains 8.1 Gbps signal fidelity; AEC-Q101 qualification supports automotive display clusters with DP inputs. |
| SATA III Data Line Protection | PCIe Gen3 Lane Protection |
Use Scenario: ESD hardening of SATA 6 Gbps differential signals in storage enclosures and motherboard headers. IC Role / Device Role / Timing Role: One D3V3X4U10LPQ protects two SATA lanes (TX+/TX− and RX+/RX−), minimizing trace length between TVS and connector. Use Value: 0.45 pF per channel avoids jitter increase beyond PCIe/SATA jitter budget; 3 A IEC 61000-4-5 rating covers surge from nearby power switching. | Use Scenario: Transient protection of PCIe Gen3 x1/x2 slots in embedded computing modules and edge AI accelerators. IC Role / Device Role / Timing Role: Placed adjacent to edge connector, protecting both transmit and receive differential pairs with matched capacitance to preserve skew. Use Value: Matched 0.45 pF channels ensure <0.1 ps inter-pair skew; low dynamic resistance prevents reflection-induced ringing during fast ESD pulses. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 4-channel low-capacitance TVS diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SZ1.8C-4 | Higher capacitance (0.8 pF), lower VRWM (1.8 V), same U-DFN2510-10 footprint | Targeted for 1.8 V logic rails; unsuitable for 3.3 V I/O due to excessive leakage at VRWM | Select only when protecting sub-2 V interfaces with tighter voltage margins |
| SP3205-04UTG | 0.5 pF capacitance, 5.5 V VBR, but no AEC-Q101 qualification or automotive PPAP support | Limited to commercial/industrial use; lacks automotive change control and IATF 16949 traceability | Prefer for cost-sensitive non-automotive designs where qualification is not required |
Compared with SZ1.8C-4 and SP3205-04UTG, D3V3X4U10LPQ uniquely balances 0.45 pF capacitance, 3.3 V VRWM compatibility, and full AEC-Q101 qualification-making it the only option qualified for automotive USB/DP interfaces requiring both signal integrity and functional safety traceability.

FAQ
What is the maximum operating temperature range for D3V3X4U10LPQ?
The D3V3X4U10LPQ is rated for operation from -55°C to +150°C, validated per AEC-Q101 stress testing. This range supports placement near heat-generating components in automotive infotainment systems and industrial USB hubs, provided thermal pad layout follows Diodes' recommended 2 oz copper land pattern.
Can D3V3X4U10LPQ be used to protect HDMI 2.0 signals?
No-HDMI 2.0 requires ≤0.25 pF per channel to maintain 6 Gbps signal integrity, but D3V3X4U10LPQ's 0.45 pF typical capacitance exceeds this limit and may cause measurable eye closure. It is validated for USB 3.1 (5 Gbps) and DisplayPort 1.4 (8.1 Gbps with margin), not HDMI 2.0.
Is the VSS pin electrically common across all four channels?
Yes-pins 3 and 8 are internally bonded to a single common cathode node shared by all four TVS diodes. Both must be connected to the same low-impedance ground plane; splitting VSS connections introduces inductance that degrades clamping performance during fast transients.
Does D3V3X4U10LPQ require external biasing or control signals?
No-it is a passive, unidirectional TVS array with no enable pins, control logic, or bias requirements. It operates solely via avalanche breakdown above VBR and requires only proper PCB layout: short traces to I/O lines, direct VSS grounding, and no series impedance between diode and protected node.
