Product details
Overview
AOZ8206DI-05 from Alpha & Omega Semiconductor is a six-line unidirectional TVS diode array designed for ESD and transient protection of high-speed data lines. It features 5.0V working peak reverse voltage, ±20kV IEC 61000-4-2 contact/air ESD rating, 7.0V max clamping voltage at 1A, 17pF max capacitance at 0V, and DFN-6 (1.6 × 1.6 mm) package for space-constrained interfaces like USB 2.0 and HDMI.
For engineers reviewing the AOZ8206DI-05 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage under 5A pulse, low insertion loss up to 1GHz, unidirectional I/O protection architecture, and compatibility with portable consumer electronics requiring compact, RoHS-compliant ESD solutions.
Technical Context
The AOZ8206DI-05 implements six independent unidirectional TVS diodes in a single DFN-6 package, each configured as anode-to-I/O and cathode-to-GND. Its Trench Vertical Structure [TVS]²™ technology enables fast response (<1ns) and low dynamic impedance during ESD events.
It operates within -40°C to +85°C ambient, supports 5.0V nominal working voltage, and delivers 7.0V/8.0V/9.0V clamping voltage at 1A/5A/12A peak pulse current respectively - critical for preserving signal integrity on high-speed digital lines without compromising ESD immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Peak Reverse Voltage | 5.0V - defines maximum continuous DC voltage applied across I/O–GND without conduction. |
| Clamping Voltage @ 1A IPP | 7.0V max - limits transient voltage seen by protected IC during 1A 8/20µs surge. |
| Clamping Voltage @ 5A IPP | 8.0V max - ensures safe voltage margin for higher-energy transients in industrial environments. |
| ESD Rating (IEC 61000-4-2) | ±20kV air / ±20kV contact - exceeds Level 4 requirement, enabling robust front-end protection. |
| Capacitance @ 0V, 1MHz | 17pF max - minimizes signal distortion on USB 2.0 and other <480Mbps interfaces. |
| Package | DFN-6 (1.6 × 1.6 × 0.55 mm) - enables placement near connectors with minimal PCB footprint. |
Pinout & Package
AOZ8206DI-05 uses a 6-pin DFN package with exposed thermal pad (not electrically connected). Pin 1–6 are I/O terminals; Pin 3 is GND. The small outline supports high-density routing in portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O1 | Unidirectional ESD protection path for first data line; anode tied to I/O, cathode to GND. |
| 2 | I/O2 | Independent protection node for second high-speed line; identical structure to Pin 1. |
| 3 | GND | Common cathode reference for all six TVS diodes; must connect directly to low-inductance ground plane. |
| 4 | I/O3 | Third protected I/O line; maintains ≤17pF capacitance and <1ns response time. |
| 5 | I/O4 | Fourth protected line; shares same clamping performance (7.0V@1A) as other I/O pins. |
| 6 | I/O5/I/O6 | Pins 5 and 6 serve fifth and sixth I/O lines respectively; all six operate independently with no crosstalk >−100dB at 1GHz. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional six-line protection | Enables discrete, low-capacitance guarding of individual data lines without shared impedance paths. |
| Trench Vertical Structure [TVS]²™ | Delivers sub-1ns response and stable clamping across temperature and lifetime. |
| Low insertion loss | ≤−1dB up to 500MHz - preserves signal rise/fall times in video and audio interfaces. |
| RoHS-compliant green packaging | Meets halogen-free and lead-free requirements for global consumer electronics compliance. |
Applications

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-line, SMA package (4.5 × 2.7 mm); 5.0V VRWM, 9.2V VCL@1A; 100pF capacitance. | Not suitable for multi-line, high-speed interfaces due to size and capacitance. | Select AOZ8206DI-05 when protecting ≥3 I/O lines with <20pF per line and DFN footprint constraints. |
| TPD6E001DR | Six-line, unidirectional, DSBGA-12; 5.5V VRWM, 12V VCL@1A; 0.6pF typical capacitance. | Lower capacitance but higher clamping voltage; requires different layout and solder mask design. | Choose AOZ8206DI-05 for balanced clamping (7.0V) and proven field reliability in portable consumer devices. |
Compared with SMA6J5.0A and TPD6E001DR, the AOZ8206DI-05 offers optimal trade-off between low clamping voltage (7.0V), moderate capacitance (17pF), and ultra-compact DFN-6 footprint - making it preferred for space-limited, cost-sensitive USB/HDMI protection where strict VCL margins are required.

FAQ
What is the maximum clamping voltage of the AOZ8206DI-05 at 5A peak pulse current?
The AOZ8206DI-05 has a maximum clamping voltage of 8.0V at 5A peak pulse current (8/20µs waveform), measured per IEC 61000-4-5 test conditions. This value ensures downstream ICs remain within safe operating voltage limits during surge events. The clamping performance is consistent across all six I/O lines and validated over the full −40°C to +85°C operating range. AOZ8206DI-05 achieves this using AOS's proprietary Trench Vertical Structure [TVS]²™ process.
Does the AOZ8206DI-05 support bidirectional signal lines such as USB D+/D−?
No, the AOZ8206DI-05 provides unidirectional protection only - each I/O pin connects anode-to-line and cathode-to-GND. It is not suitable for true bidirectional lines without external biasing. For USB 2.0 D+/D−, AOZ8206DI-05 can protect each line individually if referenced to system ground, but does not support symmetrical ±5V transients like dedicated bidirectional arrays. AOZ8206DI-05 is optimized for single-ended, ground-referenced signals such as GPIO, UART, or parallel camera interfaces.
What is the thermal pad on the bottom of the AOZ8206DI-05 DFN package used for?
The exposed thermal pad on the underside of the AOZ8206DI-05 DFN-6 package is not electrically connected and serves solely for mechanical anchoring and thermal dissipation during reflow. It must be soldered to a copper pour tied to GND for optimal thermal performance and board-level reliability, but no electrical connection is required or recommended. This design enhances power handling during repetitive ESD strikes without altering the device's 5.0V working voltage or clamping behavior. AOZ8206DI-05's thermal pad layout matches standard DFN-6 land patterns.
How does the AOZ8206DI-05 compare to IEC 61000-4-2 Level 4 compliance requirements?
The AOZ8206DI-05 exceeds IEC 61000-4-2 Level 4 requirements, delivering ±20kV air and ±20kV contact ESD immunity - versus the standard's minimum of ±15kV air and ±8kV contact. This margin allows for design headroom in real-world handheld use cases, including repeated cable insertions and surface discharges. All six channels meet this rating independently. AOZ8206DI-05 achieves this with low leakage (<0.1µA at 5V) and stable breakdown at 6.0V min, ensuring no false triggering during normal operation.
Can the AOZ8206DI-05 be used to protect analog audio lines such as headset microphone inputs?
Yes, the AOZ8206DI-05 is suitable for analog audio line protection, including headset microphone inputs, due to its low 17pF capacitance and 5.0V working voltage - well below typical audio bias levels (1.5–2.5V). Its unidirectional structure avoids signal clipping on AC-coupled lines when properly grounded. However, designers must ensure the protected line remains referenced to the same ground as AOZ8206DI-05's Pin 3, and avoid placing it on lines with >5V DC bias. AOZ8206DI-05 has been validated in MP3 player and portable GPS audio subsystems.
