Product details
Overview
DZQA5V6AXV5-7 from Diodes Incorporated is a quad-channel TVS diode array in common-anode configuration, designed for ESD and transient voltage suppression on high-speed data lines. It features a 5.6 V nominal breakdown voltage, 13 V max clamping voltage at 1.6 A, 12.3 pF typical capacitance at 3 V bias, and SOT553 ultra-small surface-mount package for space-constrained USB/USB-C, HDMI, and audio interface protection.
For engineers reviewing the DZQA5V6AXV5-7 datasheet, DZQA5V6AXV5-7 pinout, DZQA5V6AXV5-7 application, or DZQA5V6AXV5-7 equivalent, key selection criteria include per-element clamping performance, low capacitance for signal integrity, JEDEC-qualified reliability, and compatibility with IEC 61000-4-2 Level 4 (±15 kV air / ±8 kV contact) ESD protection requirements.
Technical Context
This device integrates four independent avalanche diodes in a single common-anode topology, enabling bidirectional transient suppression across four signal lines referenced to a shared ground rail. Each channel delivers 20 W peak pulse power (8/20 µs), 1 µA max reverse leakage at 3.0 V, and operates from –55 °C to +150 °C.
The SOT553 package supports high-density PCB layouts with 0.5 mm pitch terminals and 0.002 g mass. Thermal resistance is 327 °C/W (junction-to-ambient, single-diode powered), and the device meets JEDEC high-reliability standards per AEC-Q references - though not automotive-qualified unless specified with Q-suffix.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage | 5.3–5.9 V @ 1 mA - defines ESD trigger threshold before clamping conduction begins |
| Max Clamping Voltage | 13 V @ 1.6 A (8/20 µs) - limits voltage seen by protected IC during surge events |
| Capacitance @ 3 V | 11.4–12.3 pF - ensures minimal signal distortion on USB 2.0 or audio differential pairs |
| Peak Pulse Power | 20 W - sustains transient energy without failure under IEC 61000-4-5 surge conditions |
| Leakage Current | ≤1 µA @ 3.0 V - avoids DC loading of high-impedance sensor or reference lines |
| Operating Temp Range | –55 °C to +150 °C - supports industrial and under-hood applications with thermal cycling |

Applications
| USB 2.0 Interface Protection | HDMI 1.3+ Data Line Protection |
|---|---|
Use Scenario: Protecting host/device USB ports against ESD events during hot-plug insertion and cable handling. IC Role / Device Role / Timing Role: Bidirectional transient suppressor on D+ and D− differential pair, referenced to common ground. Use Value: 12.3 pF capacitance prevents eye diagram closure; 13 V clamping ensures connected PHY ICs remain within absolute maximum ratings. | Use Scenario: Safeguarding HDMI source/sink TMDS channels from electrostatic discharge during display connection/disconnection. IC Role / Device Role / Timing Role: Per-channel TVS element on each TMDS data lane (0+, 0−, 1+, 1−), sharing common anode to chassis ground. Use Value: Sub-13 V clamping preserves signal swing margin; low leakage avoids DC offset in AC-coupled video paths. |
| Audio Line ESD Suppression | Industrial Sensor Interface Protection |
Use Scenario: Shielding analog audio inputs (e.g., 3.5 mm jack line-in) from user-handling ESD in consumer audio equipment. IC Role / Device Role / Timing Role: Low-capacitance TVS on left/right channel and ground-referenced return paths. Use Value: 11.4 pF typical capacitance avoids high-frequency roll-off in 20 kHz bandwidth audio signals. | Use Scenario: Protecting RS-485 transceiver I/O pins in factory automation controllers exposed to field wiring transients. IC Role / Device Role / Timing Role: Transient clamp on A/B differential bus lines and enable/control signals. Use Value: –55 °C to +150 °C operating range ensures reliability in uncontrolled cabinet environments; 20 W rating handles induced lightning surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad TVS array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SZ1.5SMC5.0A-Q | Single-channel, higher 1.5 kW peak power, 5.0 V nominal breakdown, DO-214AB package | Requires four discrete devices; larger footprint; better for high-energy surges but unsuitable for high-speed data lines | Select only when protecting low-frequency industrial I/O where capacitance is not critical |
| SP1003-04UTG | Quad-channel, 5.5 V breakdown, 12 pF @ 0 V, SOT-23-6 package, lower 12 W peak power | Higher capacitance at 0 V bias; smaller peak power margin; same pin-compatible layout for some designs | Prefer when cost-sensitive and surge threat is limited to IEC 61000-4-2 only (not 4-5) |
Compared with SZ1.5SMC5.0A-Q and SP1003-04UTG, DZQA5V6AXV5-7 uniquely balances low capacitance (12.3 pF @ 3 V), quad integration in SOT553, and 20 W surge capability - making it optimal for miniaturized, high-speed interface protection where board space and signal fidelity are constrained.

FAQ
What is the maximum clamping voltage for DZQA5V6AXV5-7 under IEC 61000-4-2 ESD testing?
The device does not specify clamping voltage under IEC 61000-4-2 directly, but its 13 V max clamping voltage at 1.6 A (8/20 µs waveform) applies to ESD surge events. This value was measured per Note 7 in the datasheet using the standard 8/20 µs current pulse, which correlates closely with contact-discharge ESD behavior in system-level testing.
Can DZQA5V6AXV5-7 be used for bidirectional signal lines like RS-485?
Yes - its common-anode quad configuration allows bidirectional clamping on each cathode terminal relative to the shared anode (ground). When placed across differential pairs such as RS-485 A/B lines, it suppresses both positive and negative transients without polarity constraints, provided the signal swing remains within the 5.6 V breakdown threshold.
Is DZQA5V6AXV5-7 qualified for automotive applications?
No - this standard-grade part is not AEC-Q200 qualified. Diodes Incorporated offers automotive-grade variants with Q-suffix (e.g., DZQA5V6AXV5Q-7) that undergo PPAP, AEC-Q200 stress testing, and are manufactured in IATF 16949-certified facilities. The -7 suffix here denotes tape-and-reel packaging, not automotive qualification.
How does the SOT553 package affect thermal performance during repeated surge events?
With RθJA = 327 °C/W (single-diode powered), the SOT553 limits sustained power dissipation. During repetitive 8/20 µs surges, junction temperature rise remains manageable due to short pulse duration (<20 µs), but continuous operation above 380 mW total package power will cause thermal runaway. Layout with thermal vias under the common anode pad improves heat dissipation significantly.
