Product details
Overview
AOZ8804ADI from Alpha and Omega Semiconductor is an ultra-low capacitance TVS diode array designed to protect four high-speed differential I/O lines (e.g., HDMI 1.3, USB 3.0) against ESD, EFT, and lightning transients. It delivers 0.3 pF line-to-line capacitance, 5.0 V working voltage, ±15 kV IEC 61000-4-2 contact/air discharge rating, and clamps at 12.0 V (IPP = 1 A) for signal integrity preservation in digital video and computing interfaces.
For engineers reviewing the AOZ8804ADI datasheet, pinout, applications, or equivalent options, key selection criteria include its DFN-10 flow-through layout for minimal trace discontinuity, verified 6 GHz insertion loss performance, low clamping voltage under 12 A surge, and RoHS-compliant Halogen-Free packaging for HDMI/USB 3.0 port-level ESD hardening.
Technical Context
The AOZ8804ADI integrates eight steering diodes and one internal TVS in a single DFN-10 package to shunt transients from four bidirectional data lanes to VN (common reference rail). Its architecture enables simultaneous protection of two differential pairs-each lane pair shares a common clamping path to VN, not ground, minimizing ground bounce and enabling clean signal return paths.
It operates within -40°C to +85°C ambient temperature with a junction limit of +125°C, supports 5.0 V DC bias, and maintains sub-0.35 pF typical line-to-line capacitance at 1 MHz-critical for preserving eye diagram integrity at 5 Gbps (USB 3.0) and HDMI 1.3 bandwidths without requiring impedance re-tuning beyond trace width compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Line-to-Line Capacitance | 0.30 pF typical - preserves signal integrity up to 6 GHz with <0.5 dB insertion loss at 5 GHz |
| Reverse Working Voltage (VRWM) | 5.0 V - matches standard 5 V I/O supply rails in HDMI/USB 3.0 transceivers |
| Clamp Voltage (VCL) | 12.0 V @ IPP = 1 A - limits transient overvoltage to safe levels for 3.3 V/5 V interface ICs |
| ESD Rating (IEC 61000-4-2) | ±15 kV contact & air - exceeds Level 4 immunity requirement for consumer electronics |
| Package | DFN-10 (2.5 mm × 1.0 mm × 0.55 mm) - enables flow-through PCB routing with no signal detour |
| Operating Temp Range | -40°C to +85°C ambient - qualified for set-top boxes, digital TVs, and notebook environments |
| Surge Current (IEC 61000-4-5) | 2.5 A (8/20 µs) - withstands induced lightning surges on external ports |
Pinout & Package
AOZ8804ADI uses a RoHS-compliant, Halogen-Free DFN-10 package (2.5 mm × 1.0 mm × 0.55 mm) with exposed thermal pad. The pinout supports flow-through routing for HDMI and USB 3.0 differential pairs, minimizing parasitic inductance and eliminating need for vias or trace bends.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5 | I/O Channel Terminals | Connect directly to protected differential lanes (e.g., TX+/TX−, RX+/RX−); internally tied to steering diodes and TVS |
| 3, 8 | VN (Common Reference Rail) | Reference node for clamping-must be connected to stable 5 V rail, not signal ground, to avoid ground bounce |
| 6, 7, 9, 10 | No Connect (NC) | Unbonded terminals; allow mechanical stability and solder joint reliability without electrical function |
Key Features
| Feature | Design Value |
|---|---|
| Flow-through pinout for HDMI/USB 3.0 | Enables straight trace routing under device-eliminates stubs, vias, and impedance discontinuities |
| 0.3 pF line-to-line capacitance | Maintains >95% signal amplitude at 5 GHz, supporting full USB 3.0 5 Gbps eye opening |

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Semtech RClamp0524P | 0.35 pF line-to-line capacitance; 13.5 V clamp @ 1 A; same DFN-10 package but different pinout (GND-referenced) | Requires ground-plane routing and layout revision; less suitable for VN-referenced systems like HDMI 1.3 | Select when system ground is low-impedance and clamping to GND is preferred over rail-referenced clamping |
| ON Semiconductor ESD7L5.0DT5G | Single-channel 0.35 pF TVS; requires four discrete units vs. integrated 4-channel AOZ8804ADI; 14.5 V clamp @ 1 A | Higher board area, more solder joints, and mismatched channel timing vs. monolithic array | Choose only if existing design uses discrete placement or requires independent channel replacement |
Compared with RClamp0524P and ESD7L5.0DT5G, the AOZ8804ADI offers integrated 4-channel protection with rail-referenced clamping, lower capacitance (0.30 pF), and flow-through pinout-reducing layout complexity and improving signal fidelity in HDMI/USB 3.0 designs without ground plane dependency.

FAQ
What is the maximum clamping voltage of the AOZ8804ADI under a 12 A transient?
The AOZ8804ADI exhibits a maximum clamping voltage of 16.5 V for positive transients and −7.0 V for negative transients when subjected to a 12 A (8/20 µs) surge current. This value is measured between any I/O pin and ground, ensuring protected downstream ICs remain within safe voltage margins during high-energy lightning-induced surges. The AOZ8804ADI maintains this performance across its full operating temperature range of −40°C to +85°C ambient.
Does the AOZ8804ADI require connection to ground or to a power rail?
The AOZ8804ADI must be connected to a stable 5 V power rail (VN pins 3 and 8), not signal ground, to enable its rail-referenced clamping architecture. Connecting VN to ground would compromise clamping effectiveness and increase ground bounce risk. The AOZ8804ADI's internal steering diodes conduct transients toward VN, making proper 5 V rail decoupling essential for optimal performance in HDMI and USB 3.0 applications.
Can the AOZ8804ADI be used for SATA interface protection?
Yes, the AOZ8804ADI is explicitly listed in its datasheet for SATA port protection due to its 0.3 pF line-to-line capacitance, 6 GHz bandwidth, and ability to maintain signal integrity at SATA II/III speeds (3–6 Gbps). Its flow-through pinout supports direct integration into SATA differential pairs without trace detours, and its ±15 kV ESD rating meets IEC 61000-4-2 Level 4 requirements for external storage interfaces.
How does the AOZ8804ADI differ from the AOZ8802A?
The AOZ8804ADI protects four I/O lines (two differential pairs), whereas the AOZ8802A is a dual-channel variant protecting two lines. Both share the same DFN-10 package, 0.3 pF capacitance, and 5 V VRWM, but AOZ8804ADI's pinout (CH1–CH4 on pins 1,2,4,5) and internal 4-channel steering topology make it suitable for HDMI/USB 3.0, while AOZ8802A targets simpler dual-line applications like LVDS or MIPI D-PHY.
Is the AOZ8804ADI compatible with HDMI 2.0 or higher standards?
The AOZ8804ADI is validated for HDMI 1.3 (1.65 Gbps) and USB 3.0 (5 Gbps), with measured insertion loss <0.5 dB up to 6 GHz. While not officially characterized for HDMI 2.0 (6 Gbps per lane) or HDMI 2.1 (12 Gbps), its 0.3 pF capacitance and TDR performance indicate potential usability in lower-loss PCB stacks-but system-level validation including eye diagram testing at target data rates is required before deployment in HDMI 2.0+ designs. The AOZ8804ADI remains optimal for HDMI 1.3–1.4 implementations.
