Product details
Overview
D6V3H1U2LPQ-7B from Diodes Incorporated is a unidirectional transient voltage suppression (TVS) diode designed for ESD protection of high-speed data lines in portable electronics. It features a 6.5V minimum breakdown voltage, 30A peak pulse current rating, 200pF typical junction capacitance, and AEC-Q101 qualification for automotive-grade reliability in compact form factor.
For engineers reviewing the D6V3H1U2LPQ-7B datasheet, D6V3H1U2LPQ-7B pinout, D6V3H1U2LPQ-7B application, or D6V3H1U2LPQ-7B equivalent, key selection criteria include IEC 61000-4-2 ±30kV contact/air ESD rating, low-profile X1-DFN1006-2 package, clamping voltage ≤11.0V at 30A, and automotive-compliant manufacturing under IATF 16949.
Technical Context
This TVS device operates as a single-channel unidirectional clamp between signal line and ground, triggered when reverse voltage exceeds 6.5V. Its low 200pF capacitance minimizes signal distortion on USB 2.0, HDMI, or audio interfaces while maintaining robust surge immunity.
The device uses silicon avalanche structure with NiPdAu-plated copper leadframe for stable clamping performance across -65°C to +150°C. Thermal resistance of 500°C/W and 250mW power dissipation are specified for FR-4 PCB mounting per Diodes' recommended pad layout.

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A | DO-214AC package (4.5×2.7mm), 6.0V VRWM, 100pF CT, 400W PPP | Higher power handling but 10× larger footprint; unsuitable for space-constrained portable designs | Choose for industrial equipment where board space is available and higher surge energy must be absorbed |
| SP1003-010 | SOD-323 package (1.7×1.25mm), 5.5V VRWM, 0.5pF CT, 3A IPP | Lower capacitance ideal for >1Gbps interfaces, but insufficient for 30A IEC 61000-4-5 compliance | Prefer for ultra-high-speed SerDes lanes where ESD threat level is lower (e.g., internal board traces) |
Compared with SMAJ6.0A and SP1003-010, D6V3H1U2LPQ-7B uniquely balances automotive-grade reliability, 30A surge capability, and sub-1mm² footprint-making it optimal for ESD protection in next-generation mobile and automotive infotainment interfaces where space, speed, and qualification are jointly constrained.

FAQ
What is the maximum clamping voltage at 30A for D6V3H1U2LPQ-7B?
The maximum clamping voltage is 12.5V at 30A for an 8/20μs pulse, per Electrical Characteristics table on page 2 of DS42847 Rev. 1–2. This value ensures protected ICs experience less than 12.5V stress during worst-case surge events, preserving functional integrity of 5V-tolerant interfaces.
Is D6V3H1U2LPQ-7B suitable for bidirectional signal lines like USB Type-C CC pins?
No - D6V3H1U2LPQ-7B is unidirectional and intended only for signals referenced to ground (e.g., USB 2.0 D+, HDMI HPD). For bidirectional lines such as USB Type-C Configuration Channel, a bidirectional TVS like D5V0H1U2LPQ-7B must be used to protect both positive and negative ESD transients.
Does the X1-DFN1006-2 package require thermal pad soldering to PCB ground?
No - unlike larger DFN packages, the X1-DFN1006-2 variant used in D6V3H1U2LPQ-7B has no exposed thermal pad. Heat dissipation relies solely on the two copper terminals and PCB copper area, with RθJA specified at 500°C/W for standard FR-4 mounting per Diodes' recommended pad layout.
How does the ±30kV ESD rating translate to real-world usage in handheld devices?
The ±30kV rating per IEC 61000-4-2 represents worst-case human-body-model discharge under controlled lab conditions. In practice, this provides robust protection against common electrostatic events during daily handling - such as pocket-to-device discharge or finger contact after walking on carpet - significantly reducing field failure rates in certified consumer electronics.
