Product details
Overview
AOZ8829ADI-03 from Alpha and Omega Semiconductor is a 4-channel ultra-low capacitance TVS diode array designed to protect HDMI 1.4/2.0 and USB 3.0/3.1 data lines from ESD transients. It delivers 0.3 pF line-to-line capacitance, ±30 kV IEC 61000-4-2 contact/air ESD rating, 3.3 V reverse working voltage, and clamping voltage of 1.3 V at 1 A TLP, enabling signal integrity preservation in high-speed digital interfaces.
For engineers reviewing the AOZ8829ADI-03 datasheet, pinout, applications, or equivalent options, key selection criteria include channel count (4), I/O-to-I/O capacitance (0.3 pF), clamping performance (1.3 V @ 1 A), operating voltage (3.3 V), and DFN-10L package compatibility with HDMI/USB 3.x PCB flow-through routing.
Technical Context
The AOZ8829ADI-03 integrates four unidirectional TVS structures with internal steering diodes that route transients to VN (pins 3 and 8) during overvoltage events. Its architecture supports bidirectional clamping via separate positive and negative paths, with dynamic resistance of 0.2 Ω measured between 8 A and 16 A TLP current.
Designed for direct placement on differential high-speed lanes, it uses a flow-through pinout (pins 1–2–4–5 for I/O channels; pins 3/8 as common VN; pins 6/7/9/10 as NC) to minimize trace discontinuity. Junction capacitance remains stable at ≤0.69 pF across 0–5 V bias, ensuring minimal signal distortion in 5 Gbps+ interfaces.
Key Specifications

|---|---|
Use Scenario: Protecting HDMI source outputs on graphics cards or SoC-based video processors against ESD during cable hot-plug events. IC Role / Device Role / Timing Role: Front-end transient suppressor placed immediately after connector, clamping fast-rising ESD pulses before they reach serializer ICs. Use Value: Maintains 6 Gbps signal fidelity with <0.3 pF loading and prevents latch-up in TI SN65DP159 or Parade PS8408 receivers. | Use Scenario: Shielding USB 3.0 SuperSpeed differential pairs on notebook motherboard I/O headers from user-handling ESD. IC Role / Device Role / Timing Role: Per-lane TVS array aligned with SSTX+/SSTX− and SSRX+/SSRX− traces adjacent to USB connector. Use Value: Enables pass/fail compliance with USB-IF ESD test plan using single-component solution instead of discrete diodes. |
| Flat Panel Display Video Interface | Set-Top Box HDMI Input Stage |
Use Scenario: Guarding V-by-One or LVDS video bus inputs on LCD panel timing controllers against board-level ESD coupling. IC Role / Device Role / Timing Role: Four-channel clamp on parallel high-speed video lanes, referenced to local VN plane to avoid ground bounce. Use Value: Eliminates pixel corruption or frame drop during factory handling without adding series impedance to video signals. | Use Scenario: Securing HDMI input receptacles on consumer STB PCBs exposed to frequent cable insertion/removal. IC Role / Device Role / Timing Role: Primary ESD suppression element located at edge connector, shunting transients directly to chassis ground via pins 3/8. Use Value: Achieves IEC 61000-4-2 Level 4 immunity while occupying <2.5 mm² area - critical for compact STB form factors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J33A-Q | Single-channel, 33 V standoff, 600 W peak pulse power - higher VRWM and lower channel density | Requires four discrete devices and additional PCB area; lacks integrated flow-through routing | Use only when higher voltage tolerance (>12 V) is required and space constraints allow discrete implementation |
| SP3205-01HTG | 4-channel, 0.35 pF line-to-line capacitance, 5 V VRWM - higher operating voltage and slightly higher capacitance | Better suited for 5 V USB 2.0 or DisplayPort interfaces; not optimized for 3.3 V HDMI 2.0 signal swing | Select SP3205-01HTG if system uses 5 V I/O rails and requires IEC 61000-4-5 12 A surge rating |
Compared with SMA6J33A-Q and SP3205-01HTG, AOZ8829ADI-03 uniquely combines 3.3 V operation, 0.3 pF capacitance, and DFN-10L flow-through layout - making it the only option that satisfies HDMI 2.0 eye mask requirements while fitting within tight connector-proximal PCB real estate.

FAQ
What is the maximum clamping voltage of AOZ8829ADI-03 under 16 A IEC 61000-4-5 surge conditions?
The AOZ8829ADI-03 exhibits a clamping voltage of 4.6 V (positive) and −4.2 V (negative) at 16 A TLP current, per datasheet page 3. This value reflects worst-case transient suppression performance under high-energy surge stress and ensures downstream 3.3 V logic remains within safe operating limits. The 0.2 Ω dynamic resistance contributes to this controlled voltage rise.
Can AOZ8829ADI-03 be used for USB 3.1 Gen 2 (10 Gbps) applications?
AOZ8829ADI-03 is specified for USB 3.0/3.1 Gen 1 (5 Gbps) per its 0.3 pF line-to-line capacitance and characterization in HDMI 2.0 contexts. While its low capacitance supports high-frequency operation, AOS does not validate or guarantee performance at 10 Gbps signaling rates. For USB 3.1 Gen 2, consult AOS's AOZ8830ADI-03 or equivalent 0.25 pF-rated arrays.
How should the VN pins (3 and 8) of AOZ8829ADI-03 be connected on the PCB?
Pins 3 and 8 of AOZ8829ADI-03 must be tied together and connected to a low-inductance reference node - typically chassis ground or a dedicated ESD return plane. Per datasheet page 6, this connection provides the lowest-impedance path for transient current, minimizing voltage overshoot. Avoid routing VN through shared signal ground planes to prevent ground bounce in sensitive receivers.
Does AOZ8829ADI-03 support bidirectional ESD protection?
Yes, AOZ8829ADI-03 provides bidirectional protection per I/O pin pair. Its internal structure combines unidirectional TVS elements with steering diodes that conduct transients toward VN regardless of polarity. The ±30 kV IEC 61000-4-2 rating and symmetric clamping voltages (±1.3 V @ 1 A) confirm full bidirectional ESD suppression capability for both positive and negative discharge events.
Is AOZ8829ADI-03 compliant with automotive AEC-Q200 requirements?
AOZ8829ADI-03 is not AEC-Q200 qualified. Its datasheet specifies an operating junction temperature range of −40°C to +125°C, which overlaps with automotive Grade 3 requirements, but no AEC-Q200 test report or qualification statement is provided by AOS. For automotive infotainment applications, verify qualification status directly with Alpha and Omega Semiconductor or select an AEC-Q200–certified variant such as AOZ8829ADI-03Q.
