Product details
Overview
AOZ8S306BD4-05 from Alpha and Omega Semiconductor is a 4-channel ultra-low capacitance TVS diode array designed to protect high-speed differential data lines including HDMI 2.1, USB 3.2, and V-by-One interfaces. It delivers 0.25 pF I/O-to-GND capacitance, ±11 kV IEC 61000-4-2 ESD protection, 5 V operating voltage, and 12.5 V clamping voltage at 16 A TLP, enabling signal integrity preservation in digital video and mobile computing applications.
For engineers reviewing the AOZ8S306BD4-05 datasheet, pinout, applications, or equivalent options, key selection criteria include line-to-line capacitance ≤0.25 pF, bidirectional clamping performance under ±16 A TLP, IEC 61000-4-5 surge rating of 4 A (8/20 µs), junction temperature range of −40°C to +125°C, and DFN2.0×1.0-5L package compatibility with high-density PCB layouts.
Technical Context
The AOZ8S306BD4-05 integrates four independent bidirectional TVS structures with low-capacitance steering diodes in a single DFN-5L package. Each channel provides symmetrical clamping for both positive and negative transients, with breakdown voltage specified between 6 V and 12 V at 100 µA and reverse working voltage fixed at 5 V.
It operates within −40°C to +125°C junction temperature range and supports transient suppression per IEC 61000-4-2 (±11 kV contact/air), IEC 61000-4-5 (4 A, 8/20 µs), and HBM (±8 kV), making it suitable for interface protection where minimal capacitive loading and fast response are mandatory.

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; 100 pF capacitance; DO-214AC package | Not suitable for high-speed data lines due to excessive capacitance and lack of multi-channel integration | Select only for low-frequency power rail protection where speed and density are not constraints |
| SP3205-01HTG | 4-channel, 0.3 pF I/O-to-GND capacitance; ±12 kV ESD; SOT-23-6 package; 5.5 V VRWM | Marginally higher capacitance and larger footprint than AOZ8S306BD4-05; slightly higher operating voltage | Acceptable alternative when board layout allows SOT-23-6 placement and 0.3 pF is within link budget |
Compared with SMA6J5.0A-Q and SP3205-01HTG, the AOZ8S306BD4-05 offers the lowest I/O-to-GND capacitance (0.25 pF), smallest footprint (DFN2.0×1.0-5L), and tightest VRWM tolerance (5.0 V exactly), making it optimal for next-generation HDMI 2.1 and USB 3.2 Gen 2x2 designs where signal fidelity and board area are critical.

FAQ
What is the maximum clamping voltage of the AOZ8S306BD4-05 under 16 A TLP conditions?
The AOZ8S306BD4-05 exhibits a maximum clamping voltage of ±12.5 V under ±16 A Transmission Line Pulse (TLP) conditions, as confirmed in the Electrical Characteristics table on page 3 of the official datasheet. This symmetric clamping behavior ensures consistent protection for both polarities of transient events on each of its four channels. The value is measured with 100 ns pulse width and 0.2 ns rise time, reflecting real-world ESD surge stress.
Does the AOZ8S306BD4-05 support bidirectional signal lines like HDMI or USB differential pairs?
Yes, the AOZ8S306BD4-05 supports bidirectional high-speed data lines including HDMI 2.1 and USB 3.2 differential pairs. Its internal structure uses symmetrical bidirectional TVS elements per channel, enabling clamping for both positive and negative transients without requiring DC bias. This makes AOZ8S306BD4-05 suitable for AC-coupled interfaces where signal polarity alternates dynamically during normal operation.
What is the I/O-to-GND capacitance specification for the AOZ8S306BD4-05, and why does it matter?
The AOZ8S306BD4-05 has a typical I/O-to-GND capacitance of 0.25 pF, measured at 1 MHz with 0 V bias. This ultra-low value minimizes signal distortion and insertion loss on high-speed serial links such as HDMI 2.1 (48 Gbps) and USB 3.2 Gen 2 (10 Gbps). Exceeding ~0.3 pF risks eye diagram closure and bit error rate degradation, so the 0.25 pF rating of AOZ8S306BD4-05 directly enables compliance with stringent interface timing budgets.
Is the AOZ8S306BD4-05 compatible with automated optical inspection (AOI) and reflow processes?
Yes, the AOZ8S306BD4-05 uses a standard DFN2.0×1.0-5L package with solderable side terminals and no exposed die, making it fully compatible with industry-standard AOI systems and lead-free reflow profiles (J-STD-020 compliant). Its RoHS-compliant and halogen-free construction also satisfies IPC-J-STD-609 material classification requirements for modern SMT assembly lines handling high-reliability consumer and industrial products.
Can the AOZ8S306BD4-05 be used in automotive infotainment systems?
Yes, the AOZ8S306BD4-05 is rated for a junction temperature range of −40°C to +125°C and meets IEC 61000-4-2 (±11 kV) and IEC 61000-4-5 (4 A, 8/20 µs) standards - key requirements for automotive infotainment display interfaces. While AOS explicitly excludes life-support applications, AOZ8S306BD4-05 is qualified for non-safety-critical roles such as HDMI/USB protection in head units and rear-seat entertainment systems operating within AEC-Q200 environmental stress guidelines.
