Product details
Overview
AOZ8819DI-05 from Alpha & Omega Semiconductor is an ultra-low capacitance TVS diode array designed to protect four high-speed differential I/O lines (e.g., HDMI 1.4/2.0, USB 3.1) against ESD and lightning transients. It features 0.3 pF typical line-to-line capacitance at 1 GHz, 5.0 V working peak reverse voltage, ±13 kV contact ESD rating per IEC 61000-4-2, and clamps to 4 V at 2 A pulse current.
For engineers reviewing the AOZ8819DI-05 datasheet, pinout, applications, or equivalent options, key selection criteria include sub-0.4 pF capacitance at 1 GHz, flow-through DFN-10 layout compatibility with HDMI/USB 3.1 routing, low clamping voltage under 12 A surge, RoHS-compliant halogen-free packaging, and junction temperature range of −40 °C to +125 °C.
Technical Context
The AOZ8819DI-05 integrates eight surge-rated steering diodes and one internal TVS in a single DFN-10 package, enabling bidirectional clamping of transient energy to either VN (pin 3/8) or ground. Its pinout supports direct in-line placement on HDMI TX/RX or USB 3.1 SSTX/SSRX differential pairs without trace rerouting.
It operates with a 5.0 V working peak reverse voltage and delivers 0.3–0.4 pF capacitance at 1 GHz between I/O pins, ensuring minimal signal distortion up to 6 GHz. Clamping occurs at 4 V (IPP = 2 A) and 9 V (IPP = 12 A), meeting IEC 61000-4-5 (7 A, 8/20 μs) and HBM ±24 kV requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Capacitance @ 1 GHz | 0.3–0.4 pF per I/O pair - preserves signal integrity for 10 Gbps USB 3.1 and HDMI 2.0 eye diagrams |
| Working Peak Reverse Voltage | 5.0 V - matches standard 5 V I/O rail systems without overvoltage risk during normal operation |
| Clamping Voltage @ 2 A | 4 V - limits transient overvoltage to safe levels for downstream HDMI/USB PHY receivers |
| ESD Rating (IEC 61000-4-2) | ±13 kV contact / ±15 kV air - exceeds Level 4 immunity for consumer and industrial interfaces |
| Junction Temp Range | −40 °C to +125 °C - supports reliable operation in thermally demanding embedded video and computing environments |
| Package | DFN-10, 2.5 mm × 1.0 mm × 0.55 mm - enables compact, high-density PCB layouts with flow-through signal routing |
Pinout & Package
AOZ8819DI-05 uses a RoHS-compliant, halogen-free DFN-10 package (2.5 mm × 1.0 mm × 0.55 mm) with exposed thermal pad. Pin 1–2–4–5 connect to internal TVS elements for I/O protection; pins 3 and 8 are common VN terminals; pins 6, 7, 9, 10 are NC (no-connect) to enable mechanical stability and simplify soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5 | I/O Protection Channel Input | Direct connection points for four differential data lines (e.g., TX0+/TX0−, RX1+/RX1−) |
| 3, 8 | VN (Common Clamp Node) | Internal connection to TVS cathode; must be tied to stable reference (e.g., 5 V rail or low-impedance ground) |
| 6, 7, 9, 10 | No Connect (NC) | Unbonded terminals - no electrical function; used for mechanical anchoring and thermal relief |
Key Features
| Feature | Design Value |
|---|---|
| Flow-through pinout for HDMI/USB 3.1 | Enables straight trace routing under device - eliminates stubs, reduces parasitic inductance, and maintains impedance continuity |
| 0.3 pF capacitance @ 1 GHz | Minimizes insertion loss and phase distortion in 10 Gbps serial links, preserving eye opening and jitter margin |
| Four-channel protection in single package | Replaces four discrete TVS devices - saves >60% board area versus dual-channel alternatives |
| IEC 61000-4-5 compliant (7 A, 8/20 μs) | Withstands lightning-induced surges on external ports without degradation or latch-up |
Applications
| HDMI 1.4/2.0 Transmitter Protection | USB 3.1 SuperSpeed Interface |
|---|---|
Use Scenario: Protecting HDMI 2.0 source outputs (TX0+/−, TX1+/−, TX2+/−, CLK+/−) on graphics cards or set-top boxes connected to long cables. IC Role / Device Role / Timing Role: Bidirectional transient clamp placed immediately before the HDMI connector to shunt ESD and cable discharge events. Use Value: Maintains 18 Gbps signal fidelity by limiting inter-pair capacitance to ≤0.4 pF and clamping transients to ≤9 V at 12 A. | Use Scenario: Safeguarding USB 3.1 Gen 1/Gen 2 host controller differential pairs (SSTX+/−, SSRX+/−, D+/−) in notebook computers and docking stations. IC Role / Device Role / Timing Role: Low-capacitance ESD suppressor located at the USB Type-C receptacle to prevent PHY damage during hot-plug events. Use Value: Enables full compliance with USB-IF ESD test plans while sustaining <0.5 dB insertion loss up to 10 GHz. |
| MDDI Mobile Display Interface | SATA III Data Ports |
Use Scenario: Shielding MDDI high-speed pixel clock and data lanes in mobile computing devices (e.g., tablets, convertible laptops) from human-body ESD. IC Role / Device Role / Timing Role: Four-channel TVS array aligned with MDDI's four differential signal groups to preserve timing skew and jitter performance. Use Value: Delivers ±24 kV HBM robustness without degrading 1.5 Gbps MDDI eye diagram mask margin. | Use Scenario: Securing SATA III (6 Gbps) transmitter/receiver lanes on motherboards and storage controllers against connector-induced transients. IC Role / Device Role / Timing Role: Signal-line protector mounted adjacent to SATA edge connector to clamp fast-rising ESD pulses before reaching the SATA PHY. Use Value: Ensures uninterrupted link training and 6 Gbps data transfer by maintaining ≤0.4 pF channel-to-channel capacitance and ≤4 V clamping at 2 A. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J5.0A | Single-channel, SMA package, 5.0 V VRWM, 600 W peak power, 65 pF @ 1 MHz | Not suitable for multi-lane high-speed interfaces due to high capacitance and lack of integrated steering diodes | Select only for low-frequency DC power line protection where capacitance is non-critical |
| TPD4E05U06DQAR | Quad-channel, 0.5 pF @ 1 MHz, 5.0 V VRWM, ±12 kV contact ESD, DQFN-10 package | Higher 0.5 pF capacitance vs. AOZ8819DI-05's 0.3 pF - measurable impact on 10 Gbps USB 3.1 eye height | Acceptable for HDMI 1.4 or SATA III but not recommended for HDMI 2.0 or USB 3.1 Gen 2 designs requiring maximum signal integrity |
Compared with SMA6J5.0A and TPD4E05U06DQAR, the AOZ8819DI-05 uniquely combines 0.3 pF capacitance at 1 GHz, flow-through DFN-10 pinout, and 4 V clamping at 2 A - making it the only option qualified for HDMI 2.0 and USB 3.1 Gen 2 interface protection without signal degradation.

FAQ
What is the maximum clamping voltage of AOZ8819DI-05 under a 12 A transient pulse?
The AOZ8819DI-05 clamps to 9 V when subjected to a 12 A, 100 ns TLP pulse per I/O pin to ground. This value is measured under standardized transmission line pulse conditions and ensures downstream HDMI or USB PHY circuits remain within safe operating voltage margins during lightning-surge events per IEC 61000-4-5.
Does AOZ8819DI-05 support both HDMI 1.4 and HDMI 2.0 interfaces?
Yes, AOZ8819DI-05 supports both HDMI 1.4 and HDMI 2.0 interfaces. Its 0.3 pF capacitance at 1 GHz and low insertion loss up to 6 GHz maintain signal integrity for HDMI 2.0's 18 Gbps bandwidth. The DFN-10 pinout aligns directly with HDMI 2.0's four differential lane pairs (TX0–TX2, CLK), as confirmed in the manufacturer's Figure 1 and layout guidelines.
How many I/O lines does AOZ8819DI-05 protect, and which pins are active?
The AOZ8819DI-05 protects four I/O lines using pins 1, 2, 4, and 5. Pins 3 and 8 serve as common VN clamp nodes. Pins 6, 7, 9, and 10 are no-connect (NC) terminals - electrically inactive but used for mechanical stability and thermal anchoring per the DFN-10 package drawing on page 7 of the datasheet.
Is AOZ8819DI-05 compatible with lead-free reflow processes?
Yes, AOZ8819DI-05 is RoHS-compliant and halogen-free, rated for standard lead-free reflow profiles. Its MSL level is 1 (per J-STD-020), meaning it can be stored indefinitely at ≤30 °C/60% RH without baking. The device passed preconditioning per JESD22-A113 (168 hr @ 85 °C/85% RH + 3× reflow @ 260 °C), confirming robustness in high-temperature assembly.
What is the junction temperature range specified for AOZ8819DI-05?
The AOZ8819DI-05 has a specified junction temperature range of −40 °C to +125 °C, as stated in the Absolute Maximum Ratings table on page 2 of the datasheet. This allows reliable operation in extended-temperature environments such as automotive infotainment head units, industrial displays, and enclosed set-top boxes where ambient temperatures may exceed +85 °C.
