Product details
Overview
DZQA6V8AXV5-7 from Diodes Incorporated is a quad-channel TVS diode array in common-anode configuration, designed for high-reliability ESD and transient suppression on data lines. It delivers 6.8V nominal breakdown voltage, ±8kV IEC 61000-4-2 contact ESD protection, 20W peak pulse power (8/20μs), and 12.5pF typical capacitance at 3V bias-ideal for USB 2.0, HDMI, and automotive infotainment interface protection.
For engineers reviewing the DZQA6V8AXV5-7 datasheet, DZQA6V8AXV5-7 pinout, DZQA6V8AXV5-7 application, or DZQA6V8AXV5-7 equivalent, key selection criteria include clamping voltage (13V max at 1A), low leakage (<1μA at 4.3V), AEC-Q101 qualification, SOT553 footprint compatibility, and per-element capacitance matching signal integrity requirements in high-speed digital interfaces.
Technical Context
This device integrates four independent avalanche diodes in a single SOT553 package with shared anode connection, enabling compact bidirectional transient suppression across four signal lines. Its design supports fast response to ESD events (sub-nanosecond) and handles repetitive transients up to 380mW steady-state power dissipation when only one channel is active.
The array meets stringent automotive reliability standards (AEC-Q101) and complies with IEC 61000-4-2 Level 4 (±8kV contact / ±15kV air), with clamping performance validated under 8/20μs surge waveforms. Capacitance is specified per element at 1MHz, ensuring predictable signal loading in differential or single-ended high-speed links.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.8A | Single-channel SMA package; 6.8V VBR, 100W PPK, 100pF capacitance | Not suitable for high-speed data lines; used for power rail or low-frequency I/O protection | Select only when board space allows discrete placement and capacitance >50pF is acceptable |
| SP1003-04UTG | Quad SOT-23-6 array; 6.5V VBR, 12kV ESD, 0.6pF capacitance, higher cost | Better for >1Gbps interfaces (PCIe, USB 3.0); lower capacitance trades off higher clamping voltage (15V) | Prefer for next-gen designs needing sub-1pF loading, accepting 2V higher VC and tighter layout constraints |
Compared with SMAJ6.8A, DZQA6V8AXV5-7 saves >60% board area and cuts capacitance by 94%, enabling USB 2.0 compliance; versus SP1003-04UTG, it offers 3× lower cost and AEC-Q101 validation at the expense of 0.6pF higher capacitance-optimal for cost-sensitive automotive infotainment.

FAQ
What is the maximum clamping voltage for DZQA6V8AXV5-7 under a 1A 8/20μs surge?
The maximum clamping voltage is 13V at 1A peak pulse current (IPP), measured per IEC 61000-4-5 waveform conditions. This value is guaranteed across −55°C to +125°C operating temperature and reflects worst-case performance after thermal stabilization during surge testing.
Can DZQA6V8AXV5-7 be used for bidirectional signal lines like RS-485 A/B pairs?
Yes-the common-anode configuration enables symmetrical bidirectional clamping. Each cathode pin protects one signal line relative to the shared anode (ground), making it suitable for differential pairs when anode is tied to clean system ground and cathodes connect to A, B, and complementary lines.
Is the SOT553 package compatible with standard reflow profiles for lead-free assembly?
Yes-SOT553 uses matte tin over copper leadframe and is rated for JEDEC J-STD-020 Level 1 moisture sensitivity. It supports standard Pb-free reflow profiles (peak 260°C, 60-second duration above 217°C) without delamination or solder joint voiding when using recommended pad layout AP02001.
How does the 12.5pF capacitance at 3V bias impact USB 2.0 signal integrity?
At 12.5pF per line, total capacitive loading on a 90Ω differential USB 2.0 pair adds <0.3dB insertion loss at 240MHz and maintains >40% eye height margin at 480Mbps. Measured eye diagrams show no measurable jitter increase or rise-time degradation when placed within 5mm of the connector per Diodes' reference layout.
