Product details
Overview
AOZ8806DI-05 from Alpha & Omega Semiconductor is an ultra-low capacitance TVS diode array designed to protect six high-speed data lines (e.g., USB 3.0 differential pairs, HDMI, Thunderbolt) against ESD, EFT, and lightning surges. It features 0.3 pF line-to-line capacitance, 5.0 V working peak reverse voltage, ±15 kV IEC 61000-4-2 contact/air discharge rating, and clamps transients to ≤9.0 V at 4 A (8/20 µs).
For engineers reviewing the AOZ8806DI-05 datasheet, pinout, applications, or equivalent options, key selection criteria include low signal distortion up to 6 GHz, minimal PCB layout impact due to drop-in I/O alignment, RoHS-compliant 3.3 mm × 1.3 mm DFN-8 package, and validated performance in USB 3.0 (5 Gbps/10 Gbps) and HDMI 1.4 eye diagrams.
Technical Context
The AOZ8806DI-05 integrates twelve surge-rated steering diodes and one internal TVS in a single 8-lead DFN package, enabling bidirectional clamping of transient energy to VCC or GND. Its architecture supports simultaneous protection of three differential pairs (six I/O lines), with each path rated for 4 A (8/20 µs) peak pulse current and ≤9.0 V clamping voltage.
Designed for high-frequency integrity, it delivers <−25 dB insertion loss up to 6 GHz and maintains signal fidelity per USB 3.0 and HDMI 1.4 compliance testing. The device operates across −40 °C to +85 °C ambient, with junction temperature rated to +125 °C and storage range from −65 °C to +150 °C.

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-Q | Single-channel, 5.0 V unidirectional TVS; 600 W peak power; 100 pF typical capacitance | Requires six discrete devices for full USB 3.0 protection; unsuitable for >1 GHz data rates due to high capacitance | Select only for low-speed DC power rail protection where signal integrity is not critical |
| SP3222-04UTG | Quad-channel, 5.0 V bi-directional TVS; 0.5 pF typical capacitance; 12 kV ESD rating | Protects four lines only; lacks integrated steering diodes for VCC-to-GND clamping; lower surge rating (2 A vs. 4 A) | Acceptable for cost-sensitive USB 2.0 or LVDS interfaces but insufficient for USB 3.0 10 Gbps or HDMI 1.4 compliance |
Compared with SMA6J5.0A-Q and SP3222-04UTG, the AOZ8806DI-05 uniquely combines six-line protection, 0.3 pF capacitance, 4 A surge rating, and integrated steering+TVS architecture-enabling single-device, high-fidelity safeguarding of next-generation high-speed serial interfaces without compromising PCB layout simplicity or signal integrity.

FAQ
What is the maximum clamping voltage of the AOZ8806DI-05 under IEC 61000-4-5 surge conditions?
The AOZ8806DI-05 has a maximum clamping voltage of 9.0 V when subjected to a 4 A, 8/20 µs current pulse per IEC 61000-4-5. This value is measured across each I/O line relative to GND or VCC, ensuring protected ICs experience minimal overvoltage stress during lightning-induced transients. The AOZ8806DI-05 achieves this with low dynamic impedance and integrated steering diode topology.
Does the AOZ8806DI-05 support both contact and air discharge ESD per IEC 61000-4-2 Level 4?
Yes, the AOZ8806DI-05 is rated for ±15 kV contact discharge and ±15 kV air discharge per IEC 61000-4-2 Level 4. These values are verified through standardized testing with 150 pF/330 Ω network and reflect the device's ability to absorb and divert ESD energy without degradation. The AOZ8806DI-05 maintains its 0.3 pF capacitance and 5.0 V working voltage throughout repeated ESD events.
Can the AOZ8806DI-05 be used to protect USB 3.1 Gen 2 (10 Gbps) interfaces?
Yes, the AOZ8806DI-05 is validated for USB 3.1 Gen 2 operation, as confirmed by published 10 Gbps eye diagram testing showing no measurable jitter or amplitude loss. Its 0.3 pF line-to-line capacitance and <−25 dB insertion loss up to 6 GHz ensure signal integrity is preserved. The AOZ8806DI-05's pinout aligns directly with USB 3.1 differential pair routing, enabling drop-in integration without layout redesign.
What is the thermal performance limit of the AOZ8806DI-05 in continuous operation?
The AOZ8806DI-05 has a maximum junction temperature of +125 °C and operates over an ambient range of −40 °C to +85 °C. Its DFN-8 package includes an exposed thermal pad that must be soldered to a PCB copper pour for effective heat dissipation. Under normal ESD/EFT transient conditions, self-heating is negligible; continuous DC leakage remains below 1.0 µA at 5.0 V VRWM, minimizing steady-state thermal load. The AOZ8806DI-05 does not require derating for standard endpoint use cases.
How does the AOZ8806DI-05 differ from the AOZ8806DI-03 variant?
The AOZ8806DI-05 has a 5.0 V working peak reverse voltage and 6.0 V minimum breakdown voltage, whereas the AOZ8806DI-03 is rated for 3.3 V VRWM and 3.5 V VBR. Both share identical 0.3 pF capacitance, ±15 kV ESD rating, and 8-lead DFN package. The AOZ8806DI-05 is selected for 5 V-biased interfaces like legacy USB 2.0 sideband lines or HDMI HPD, while AOZ8806DI-03 suits 3.3 V logic such as PCIe or SATA.
