Product details
Overview
D3V3F8U9LP3810 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, 5A IEC 61000-4-5 lightning surge rating, 0.55pF typical channel input capacitance, ±12kV IEC 61000-4-2 ESD contact/air immunity, and 5V clamping voltage at 16A TLP-enabling robust signal integrity in USB 3.0/3.1 and DisplayPort interfaces.
For engineers reviewing the D3V3F8U9LP3810 datasheet, D3V3F8U9LP3810 pinout, D3V3F8U9LP3810 application, or D3V3F8U9LP3810 equivalent, key selection criteria include ultra-low 0.55pF capacitance for <10Gbps data rates, sub-5V clamping performance under 16A TLP stress, validated U-DFN3810-9 (Type B) package thermal resistance (360°C/W), and automotive-grade manufacturability per IATF 16949.
Technical Context
This device implements eight independent bidirectional TVS diodes in a single U-DFN3810-9 (Type B) package, each with a 3.3V reverse working voltage and 5.5V minimum breakdown threshold. Its 0.25Ω dynamic resistance (TLP, 10A) ensures rapid voltage clamping during transient events, while the 0.55pF input capacitance minimizes signal distortion on differential high-speed lanes.
The architecture supports simultaneous protection of eight I/O lines without shared ground-path coupling, with verified ±12kV ESD immunity (IEC 61000-4-2) and 5A 8/20µs surge capability (IEC 61000-4-5). Thermal design is optimized for FR-4 PCB layouts with 2oz copper, delivering 350mW power dissipation and 360°C/W junction-to-ambient resistance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-channel low-capacitance TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1006-08UTG | 0.8pF CI/O, 6.5V VBR(min), 6.8V VC@16A - higher capacitance and clamping voltage | Limited to USB 2.0/3.0 (5Gbps) due to 0.8pF capacitance; unsuitable for DP 1.4 or PCIe 3.0 | Select when cost sensitivity outweighs 10Gbps signal integrity requirements and board space allows larger U-DFN2510-10 package |
| TPD8S300DRBR | 0.45pF CI/O, 3.6V VRWM, 5.5V VC@16A - lower VRWM but tighter clamping tolerance | Optimized for mobile USB-C ports with tighter voltage margins; lacks IATF 16949 manufacturing certification | Prefer for consumer handhelds where 0.45pF advantage enables marginally better 10Gbps eye opening, but avoid in automotive or industrial OEM designs requiring PPAP |
Compared with SP1006-08UTG and TPD8S300DRBR, D3V3F8U9LP3810 uniquely balances 0.55pF capacitance, 5V clamping, and IATF 16949 production - making it optimal for industrial USB 3.1/DP 1.4 systems requiring both signal fidelity and supply-chain traceability.

FAQ
What is the maximum operating temperature range for D3V3F8U9LP3810?
The D3V3F8U9LP3810 operates reliably from –55°C to +150°C ambient temperature, validated per JEDEC JESD22-A104 thermal cycling and JESD22-A108 high-temperature operating life tests. This range supports deployment in under-hood automotive modules and industrial control cabinets without derating.
Does D3V3F8U9LP3810 require external biasing or control signals?
No. The D3V3F8U9LP3810 is a passive bidirectional TVS array with no external bias, enable, or configuration pins. It functions solely as a voltage-clamping device between each I/O line and ground, activating automatically when transient voltage exceeds its breakdown threshold of 5.5V.
How does the U-DFN3810-9 (Type B) package affect thermal performance?
The U-DFN3810-9 (Type B) package achieves 360°C/W junction-to-ambient thermal resistance when mounted on a standard FR-4 PCB with 2oz copper and the exposed pad (Pin 9) fully soldered to an internal ground plane. This enables 350mW continuous power dissipation without exceeding 150°C junction temperature at 25°C ambient.
Can D3V3F8U9LP3810 replace discrete TVS diodes in existing USB 3.0 designs?
Yes-its pin-compatible layout with eight independent channels and shared cathode structure allows direct replacement of discrete 8-diode arrays. However, verify PCB pad dimensions against Diodes' suggested U-DFN3810-9 layout (0.20mm b, 3.80mm D, 1.00mm E) and confirm ground plane connectivity to Pin 9 to maintain specified 0.55pF capacitance and thermal performance.
