Product details
Overview
AOZ8802ADI from Alpha & Omega Semiconductor is an ultra-low capacitance TVS diode array designed to protect dual high-speed data lines (e.g., USB 2.0 D+/D−) against ESD, EFT, and lightning transients. It delivers 0.3pF line-to-line capacitance, 5.0V working peak reverse voltage, ±15kV IEC 61000-4-2 contact/air discharge rating, and clamping voltages of 12V/–3V at 1A, enabling HDMI 1.3 and USB 2.0 signal integrity preservation in compact consumer electronics.
For engineers reviewing the AOZ8802ADI datasheet, pinout, applications, or equivalent options, key selection criteria include its DFN-6 flow-through layout for minimal parasitic inductance, verified 6GHz insertion loss performance, dual-channel protection architecture, and RoHS-compliant halogen-free packaging suitable for space-constrained mobile and display interfaces.
Technical Context
The AOZ8802ADI integrates four surge-rated steering diodes with an internal TVS element in a monolithic structure, enabling bidirectional transient shunting to VN (ground) or VCC (5V rail). Its channel-specific clamping behavior-12V positive / –3V negative at 1A-ensures low-voltage logic compatibility while maintaining sub-1ns response time per IEC 61000-4-2.
Designed for differential signaling paths, it maintains matched 0.3pF I/O–I/O capacitance and 0.65pF I/O–ground capacitance, minimizing skew and crosstalk up to 6GHz. The DFN-6 package's symmetric pinout (pins 1–3 tied internally to ground/TVS, pins 4–6 NC) supports direct in-line placement without trace routing detours.

Pinout & Package
AOZ8802ADI uses a RoHS-compliant, halogen-free DFN-6 package measuring 1.6mm × 1.0mm × 0.55mm with exposed thermal pad. Pin 1 is marked by dot; pins 1–3 connect internally to ground and TVS elements, while pins 4–6 are no-connect terminals for mechanical stability during reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Anode / Ground Tie | Internally connected to cathode of CH1 steering diode and TVS ground node - forms low-inductance path for transient current. |
| 2 | Channel 2 Anode / Ground Tie | Internally connected to cathode of CH2 steering diode and same TVS ground node - enables common-mode transient suppression. |
| 3 | Ground / TVS Cathode | Dedicated low-impedance ground terminal for TVS element - minimizes clamping voltage overshoot via shortest PCB return path. |
| 4 | No Connect | Mechanical anchor only - no electrical function; must remain unconnected to avoid parasitic coupling. |
| 5 | No Connect | Mechanical anchor only - ensures coplanarity and solder joint reliability on fine-pitch DFN footprint. |
| 6 | No Connect | Mechanical anchor only - provides symmetrical thermal mass distribution across package body. |
Key Features
| Feature | Design Value |

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 (4.5 × 2.7 mm), 5.0V VRWM, 600W PPPK, 60pF capacitance | Not suitable for high-speed differential lines due to excessive capacitance; limited to DC/low-frequency power rail protection | Select only for non-data-line 5V rail clamping where board space and speed are not constraints. |
| TPD2E001DRSR | Two-channel, DRSR (2 × 2 mm), 5.5V VRWM, 0.8pF line-to-line capacitance, ±8kV IEC 61000-4-2 | Lower ESD rating and higher capacitance reduce margin for HDMI 1.3 and USB 2.0 full-speed compliance | Acceptable for cost-sensitive USB-only designs where ±8kV air discharge suffices and 0.8pF capacitance is tolerable. |
Compared with SMA6J5.0A and TPD2E001DRSR, the AOZ8802ADI uniquely combines dual-channel protection, 0.3pF capacitance, ±15kV ESD rating, and DFN-6 flow-through layout-making it the only option qualified for simultaneous HDMI 1.3 and USB 2.0 interface hardening in space-constrained consumer platforms.

FAQ
What is the primary circuit role of the AOZ8802ADI in a USB 2.0 design?
The AOZ8802ADI serves as a bidirectional transient voltage suppressor placed directly at the USB connector to clamp ESD and surge events on D+ and D− lines before they reach the USB PHY. Its 0.3pF line-to-line capacitance and flow-through pinout preserve signal integrity at 480Mbps, while its ±15kV IEC 61000-4-2 rating ensures robust protection in real-world handling conditions. The AOZ8802ADI achieves this without requiring series resistors or layout compromises.
Does the AOZ8802ADI support HDMI 1.3 compliance?
Yes, the AOZ8802ADI supports HDMI 1.3 compliance through its 0.3pF line-to-line capacitance, which minimizes insertion loss and jitter on TMDS differential pairs up to 165MHz pixel clocks. Its 6GHz bandwidth and low clamping voltage (12V/–3V at 1A) prevent eye diagram degradation and ensure stable video transmission in digital TVs and set-top boxes. The AOZ8802ADI is explicitly validated for HDMI 1.3 applications in its datasheet.
How does the DFN-6 package pinout of the AOZ8802ADI reduce PCB parasitics?
The AOZ8802ADI's DFN-6 pinout places pins 1–3 as grounded terminals aligned with the signal path, enabling straight "flow-through" PCB trace routing without vias or bends. Pins 4–6 are no-connect anchors that improve solder joint reliability without adding parasitic capacitance. This layout reduces loop inductance by >30% compared to conventional L-shaped TVS placements, directly lowering clamping voltage overshoot during ESD events. The AOZ8802ADI's mechanical design thus enhances electrical performance intrinsically.
What is the maximum operating temperature range for the AOZ8802ADI?
The AOZ8802ADI is rated for an ambient operating temperature range of –40°C to +85°C, with a junction temperature limit of –40°C to +125°C. This range supports deployment in thermally demanding consumer enclosures such as digital TVs, gaming consoles, and portable media players. The DFN-6 package's exposed thermal pad facilitates efficient heat dissipation, ensuring stable clamping performance across the full industrial temperature span. The AOZ8802ADI maintains specified electrical characteristics within this range.
Can the AOZ8802ADI protect both USB and HDMI interfaces simultaneously on the same PCB?
Yes, the AOZ8802ADI can protect both USB and HDMI interfaces when deployed per-interface-each AOZ8802ADI safeguards one differential pair (e.g., USB D+/D− or HDMI TMDS clock). Its dual-channel architecture, 0.3pF capacitance, and 6GHz bandwidth make it suitable for either application without redesign. Layout best practices require placing one AOZ8802ADI at each connector, with short traces to ground. The AOZ8802ADI's consistent performance across protocols simplifies BOM consolidation for multi-interface consumer devices.
