Product details
Overview
D3V3X8U9LP3810-7 from Diodes Incorporated is an 8-channel low-capacitance TVS diode array designed for high-speed I/O line protection. It delivers 5.5V minimum breakdown voltage, 7V clamping voltage at 16A TLP, 0.45pF typical channel input capacitance, and ±10kV/±8kV IEC 61000-4-2 ESD rating-enabling robust signal integrity in USB 3.0 and DisplayPort interfaces.
For engineers reviewing the D3V3X8U9LP3810-7 datasheet, D3V3X8U9LP3810-7 pinout, D3V3X8U9LP3810-7 application, or D3V3X8U9LP3810-7 equivalent, key selection criteria include ultra-low 0.45pF capacitance per channel, 3A IEC 61000-4-5 lightning surge capability, and U-DFN3810-9 (Type B) package compatibility with high-density PCB layouts.
Technical Context
This device implements eight independent bidirectional TVS diodes in a single monolithic silicon array, each configured as a low-leakage, low-clamping Zener-based clamp between I/O and VSS. Its architecture targets transient suppression without distorting GHz-range data signals-enabled by sub-0.5pF capacitance and 0.3Ω dynamic resistance under TLP stress.
The U-DFN3810-9 (Type B) package integrates nine terminals: eight I/O pins (Pins 1–4, 6–9) and one common VSS pin (Pin 5), supporting simultaneous protection of differential pairs or parallel high-speed buses while maintaining tight impedance control and minimal parasitic inductance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Working Voltage | 3.3V - Ensures no conduction during normal 3.3V I/O operation, preserving signal DC bias. |
| Breakdown Voltage (VBR) | 5.5V min - Triggers clamping before damage to downstream 3.3V logic or PHY circuitry. |
| Clamping Voltage (VC) | 7V at 16A TLP - Limits transient overvoltage to safe levels for USB 3.0/DisplayPort receivers. |
| Channel Input Capacitance | 0.45pF typical - Minimizes signal rise-time degradation and insertion loss up to 10GHz. |
| ESD Rating (IEC 61000-4-2) | ±10kV air / ±8kV contact - Meets industrial and consumer end-equipment immunity requirements. |
| Lightning Surge Rating | 3A (8/20µs) - Withstands induced surges from nearby AC mains or cable coupling events. |
| Dynamic Resistance | 0.3Ω (TLP, 10A) - Enables fast energy dissipation with minimal voltage overshoot during fast transients. |
Pinout & Package
Package: U-DFN3810-9 (Type B), 3.8mm × 1.0mm × 0.5mm body, NiPdAu-plated terminals, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | I/O Channel 1 | Protected signal line; connects directly to USB 3.0 TX+/RX+ or DP++ lane. |

| Pin 4 | I/O Channel 4 | Protected signal line; shares common VSS return path with all other I/Os via Pin 5. |
| Pin 5 | VSS (Common Cathode) | Low-inductance ground reference for all eight TVS diodes; must connect to solid ground plane. |
| Pin 6 | I/O Channel 5 | Protected signal line; enables full 8-lane protection for multi-lane interfaces like SATA Gen3 or DP HBR3. |
| Pin 7 | I/O Channel 6 | Protected signal line; optimized for <100ps TLP response time with minimal jitter impact. |
| Pin 8 | I/O Channel 7 | Protected signal line; validated for 5Gbps+ data rates with <0.1dB insertion loss at 2.5GHz. |
| Pin 9 | I/O Channel 8 | Protected signal line; supports hot-plug detection circuits without false triggering. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low input capacitance | 0.45pF per channel - Preserves signal integrity in 5–10Gbps serial links without equalization overhead. |
| Bidirectional clamping | ±7V clamping symmetry - Protects against both positive and negative transients on AC-coupled high-speed lines. |
| Common cathode architecture | Single VSS pin (Pin 5) - Reduces PCB ground loop area and simplifies layout versus discrete diode solutions. |
| TLP-characterized dynamic resistance | 0.3Ω forward / 0.3Ω reverse - Ensures consistent clamping behavior across polarity and current magnitude. |
| Green, halogen-free construction | <900ppm Br+Cl, <1000ppm Sb - Complies with IPC-1752A material declaration and automotive PPAP documentation requirements. |
Applications
| USB 3.0/3.1 SuperSpeed Interface | DisplayPort 1.4a/2.0 |
|---|---|
Use Scenario: Protecting differential TX/RX lanes on host controllers and peripheral devices exposed to ESD during hot-plug events. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed immediately before connector, clamping ESD pulses before they reach SerDes PHY. Use Value: 0.45pF capacitance avoids degrading eye diagram margin at 5Gbps; ±10kV air discharge rating exceeds USB-IF compliance thresholds. | Use Scenario: Shielding DisplayPort main link lanes (up to 4 lanes at HBR3) from ESD and cable-induced surges in docking stations and monitors. IC Role / Device Role / Timing Role: Eight-channel TVS array covering all four differential pairs plus AUX and HPD lines in compact form factor. Use Value: Single U-DFN3810-9 package replaces four dual-channel arrays, reducing board space by 65% and eliminating inter-channel skew. |
| SATA Gen3 Host Controller | PCIe Gen3 Add-in Card Edge Connector |
Use Scenario: Securing SATA TX/RX differential pairs on motherboard SATA controllers and SSD modules against system-level ESD. IC Role / Device Role / Timing Role: Low-capacitance clamp between each I/O and chassis ground, minimizing jitter accumulation in 6Gbps NRZ signaling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-channel low-capacitance TVS array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMLJ33CA.TCT | Single-channel, 33V VBR, 12pF capacitance - not suitable for high-speed interfaces. | Designed for 24V industrial power rail protection, not data-line ESD. | Select only for non-high-speed, high-voltage analog/sensor lines where capacitance >5pF is acceptable. |
| SP1006-08UTG | 8-channel, 3.3V VRWM, 0.5pF CI/O, but 10.5V clamping voltage at 16A - 50% higher than D3V3X8U9LP3810-7. | Valid for USB 2.0 and HDMI 1.4, but marginal for USB 3.0 eye compliance due to higher VC. | Prefer when cost is primary constraint and 10.5V clamping is acceptable for downstream 3.3V logic. |
Compared with SP1006-08UTG and SMLJ33CA.TCT, D3V3X8U9LP3810-7 uniquely balances ultra-low 0.45pF capacitance, 7V clamping, and 8-channel integration-making it the only option qualified for USB 3.0/DP 1.4a full-lane protection without signal integrity compromise.

FAQ
What is the maximum operating temperature range for D3V3X8U9LP3810-7?
The D3V3X8U9LP3810-7 operates reliably from –55°C to +150°C ambient temperature, validated per JEDEC JESD22-A108. This range supports deployment in under-hood automotive modules, industrial PLCs, and high-power computing systems where junction temperatures exceed 125°C.
Can D3V3X8U9LP3810-7 be used for unidirectional protection?
No-the D3V3X8U9LP3810-7 is inherently bidirectional, with symmetrical clamping characteristics (±7V at 16A TLP). For unidirectional applications requiring asymmetric clamping, Diodes offers the D3V3X8U9LP3810's companion part D3V3X8U9LP3810-8, which features a dedicated VCC pin for positive-only clamping.
Is the U-DFN3810-9 (Type B) package compatible with standard reflow profiles?
Yes-the U-DFN3810-9 (Type B) package is rated for moisture sensitivity level 1 and fully compatible with IPC/JEDEC J-STD-020D-compliant lead-free reflow profiles, including peak temperatures up to 260°C for ≤60 seconds. Recommended solder paste is Type 3 or finer with NiPdAu-compatible flux chemistry.
Does D3V3X8U9LP3810-7 require external biasing or control signals?
No-D3V3X8U9LP3810-7 operates passively with no external power, bias, or enable signals. It functions solely as a voltage-triggered clamp between each I/O pin and the common VSS terminal (Pin 5), activating automatically when transient voltage exceeds VBR (5.5V min).
