Product details
Overview
D3V3F4U10LPQ-7 from Diodes Incorporated is a 4-channel, low-capacitance TVS diode array designed for ESD protection of high-speed I/O lines. It features 0.5pF typical channel input capacitance, 5.5V minimum breakdown voltage, 5A IEC 61000-4-5 lightning surge rating, ±12kV IEC 61000-4-2 ESD immunity, and 5V clamping voltage at 16A TLP, making it suitable for USB 3.0/3.1 and DisplayPort interfaces.
For engineers reviewing the D3V3F4U10LPQ-7 datasheet, D3V3F4U10LPQ-7 pinout, D3V3F4U10LPQ-7 application, or D3V3F4U10LPQ-7 equivalent, key selection criteria include ultra-low capacitance for signal integrity, AEC-Q101 qualification for automotive use, U-DFN2510-10 package footprint compatibility, and verified clamping performance under IEC-compliant transient waveforms.
Technical Context
This device implements four independent bidirectional TVS diodes in a single U-DFN2510-10 package, each with a 3.3V reverse working voltage and 5.5V minimum breakdown threshold. Its 0.25Ω TLP dynamic resistance ensures rapid voltage clamping during fast transients, while the 0.5pF input capacitance minimizes signal distortion on differential high-speed links.
The device operates across –55°C to +150°C and is rated for 5A (8/20µs) surge current per channel to VSS. It meets IEC61000-4-2 (±12kV contact/air), IEC61000-4-5 (5A), and AEC-Q101 stress requirements, with thermal resistance of 360°C/W on standard FR-4 layout.
Key Specifications

|---|---|
|
Use Scenario: Protecting differential TX/RX pairs on host-side USB 3.0/3.1 controllers against ESD events during cable insertion and hot-plug operations. IC Role / Device Role: Bidirectional transient voltage suppressor placed directly at connector entry point, shunting ESD energy to chassis ground. Use Value: 0.5pF capacitance avoids eye diagram degradation at 5–10 Gbps; 5V clamping prevents damage to SerDes PHYs rated for ≤3.6V absolute max. |
Use Scenario: Shielding DisplayPort main link lanes (CH0–CH3) on GPU or source device outputs from electrostatic discharge during docking or cable handling. IC Role / Device Role: Four-channel TVS array integrated into DP++ receptacle layout, with VSS tied to shield ground plane.

| SATA III 6Gbps Host Controller | Automotive Infotainment USB-C Port |
|
Use Scenario: Safeguarding SATA differential pairs on motherboard or storage controller from ESD during drive hot-swap or enclosure maintenance. IC Role / Device Role: Low-capacitance TVS array mounted adjacent to SATA connector, with minimal trace length to preserve impedance continuity. Use Value: 0.25Ω dynamic resistance ensures clamping within 1ns; 5.5V VBR avoids false triggering during 3.3V SATA signaling swings. |
Use Scenario: ESD protection for USB-C receptacles in automotive head units or rear-seat entertainment systems exposed to passenger interaction. IC Role / Device Role: AEC-Q101-qualified TVS array used on both CC and high-speed lanes, with VSS connected to vehicle chassis ground. Use Value: Validated for –40°C to +125°C operation; RoHS 3 and halogen-free compliance satisfies OEM material declarations (IMDS, CAMDS). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J3.3A-Q | Single-channel, SMA package, 3.3V VRWM, 12.3V VBR MIN, 12pF CI/O | Not suitable for multi-lane high-speed interfaces due to higher capacitance and discrete layout | Use only for low-speed, single-line protection where board space and cost outweigh signal integrity needs |
| SP1006-04UTG | 4-channel, SOT-23-6 package, 3.3V VRWM, 5.5V VBR MIN, 0.6pF CI/O, ±15kV ESD | Larger footprint (3.0 × 1.75 mm), slightly higher capacitance, no AEC-Q101 qualification | Preferred for industrial non-automotive designs requiring higher ESD margin but lacking space constraints |
Compared with SMA6J3.3A-Q and SP1006-04UTG, D3V3F4U10LPQ-7 uniquely combines automotive qualification, ultra-low 0.5pF capacitance, and compact U-DFN2510-10 packaging-enabling direct integration into space-constrained, high-reliability USB/DP port designs without compromising signal fidelity or compliance.

FAQ
What is the maximum operating temperature for D3V3F4U10LPQ-7?
The device operates from –55°C to +150°C, validated per AEC-Q101 thermal cycling and high-temperature operating life tests. Its 360°C/W junction-to-ambient thermal resistance assumes mounting on a 2oz copper FR-4 pad layout per Diodes' recommended footprint.
Can D3V3F4U10LPQ-7 protect both USB 3.1 Gen 2 and DisplayPort 1.4 simultaneously?
Yes - its 0.5pF typical input capacitance and 5V clamping voltage at 16A TLP meet the signal integrity and voltage tolerance requirements of both standards. Each of the four channels independently protects one differential pair without crosstalk or bandwidth limitation up to 10 GHz.
Is the U-DFN2510-10 package compatible with standard reflow profiles?
Yes - the package is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 and supports peak reflow temperatures up to 260°C. Its NiPdAu plating ensures solderability per MIL-STD-202, Method 208, with no pre-bake required.
Does D3V3F4U10LPQ-7 require external biasing or control signals?
No - it is a passive, bidirectional TVS array with no external connections beyond the four I/O pins and two VSS pins. It operates automatically during transients without power supply, enable signals, or configuration registers.
