Product details
Overview
D6V3H1U2LP4-7B from Diodes Incorporated is a unidirectional transient voltage suppression (TVS) diode designed for ESD protection of single I/O lines in portable electronics. It features a 6.5V minimum breakdown voltage, 30A peak pulse current (8/20µs), 200pF typical junction capacitance, and ±30kV IEC 61000-4-2 contact/air discharge rating - deployed in cellular handsets to safeguard USB/USB-C, audio jack, and SIM card interfaces.
For engineers reviewing the D6V3H1U2LP4-7B datasheet, D6V3H1U2LP4-7B pinout, D6V3H1U2LP4-7B application, or D6V3H1U2LP4-7B equivalent, key selection criteria include clamping voltage at 20A (9.0V max), low-profile X2-DFN1006-2 package (1.08 × 0.68 mm), RoHS-3 and halogen-free compliance, and thermal resistance of 500°C/W on FR-4.
Technical Context
This TVS diode operates as a unidirectional clamping device between an I/O line and ground, triggering conduction above 6.5V reverse breakdown to divert ESD transients. Its 9.0V clamping voltage at 20A ensures logic-level signal integrity for 3.3V/5V interfaces while limiting voltage overshoot during surge events.
The X2-DFN1006-2 package integrates NiPdAu-plated copper terminals and a UL 94V-0 green molding compound, enabling reflow soldering per MIL-STD-202 Method 208 and supporting moisture sensitivity level 1 handling without baking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 6.3V - Maximum continuous reverse working voltage before leakage exceeds 1µA; sets upper limit for safe operation on 5V or 3.3V data lines. |
| VBR (min) | 6.5V - Guaranteed reverse breakdown threshold at 1mA; ensures reliable turn-on before downstream IC damage thresholds. |
| VCL @ 20A | 9.0V max - Clamped voltage during 8/20µs surge; keeps protected IC I/O pins below 10V absolute maximum rating. |
| IPP | 30A - Peak pulse current capability under 8/20µs waveform; meets IEC 61000-4-5 Level 3 lightning surge immunity. |
| CT | 200pF - Junction capacitance at 0V bias and 1MHz; enables use on high-speed interfaces like USB 2.0 (480Mbps) without signal distortion. |
| PPP | 375W - Peak pulse power dissipation; defines transient energy absorption capacity for short-duration ESD events. |
Pinout & Package
Package: X2-DFN1006-2 - ultra-compact, 2-terminal, bottom-exposed thermal pad-less surface-mount package with 1.08mm × 0.68mm footprint and 0.40mm max height. Terminals are NiPdAu over copper leadframe; pin 1 marked by bar on cathode side.

| Pin 2 | Anode | Connected to system ground (GND); provides return path for diverted ESD current; requires low-inductance PCB routing. |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000-4-2 ESD Rating | ±30kV air/contact - exceeds industrial and consumer ESD immunity requirements without external shielding. |
| Low Profile & Small Footprint | 0.40mm max height, 1.08 × 0.68mm area - fits tight spaces in slim smartphones and wearables near connectors. |
| Halogen & Antimony Free | <900ppm Br, <900ppm Cl, <1000ppm Sb - satisfies strict environmental compliance for EU, Japan, and China RoHS-equivalent markets. |
| Thermal Performance | RθJA = 500°C/W on FR-4 - enables stable operation up to +85°C ambient in sealed handheld enclosures. |
Applications

|---|---|
Use Scenario: Protecting touchscreen controller I/O, proximity sensor, and earpiece amplifier inputs from user-hand ESD during daily handling. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed directly at connector entry point to shunt ESD to GND before reaching ASIC GPIOs. Use Value: Prevents latch-up or gate oxide damage in 28nm/40nm mobile SoCs by limiting transient voltage to ≤9.0V at 20A surge. | Use Scenario: Safeguarding D+ and D− differential pairs in smartphone USB-C receptacles against repeated plug/unplug ESD events. IC Role / Device Role / Timing Role: Low-capacitance (200pF) TVS placed adjacent to connector to preserve signal rise/fall time and eye diagram integrity. Use Value: Maintains USB 2.0 full-speed timing margin (≤17ns rise time) while passing ±30kV IEC 61000-4-2 testing. |
| Digital Camera Button & Lens Control | MP3 Player Audio Jack Interface |

IC Role / Device Role / Timing Role: Low-leakage (0.1µA typ) TVS ensuring no DC offset or noise injection into audio amplifiers during standby. Use Value: Eliminates audible pop/crackle during jack insertion by preventing ESD-induced bias rail disturbance in Class AB headphone drivers. |
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, 30A IPP, 600pF CT | Higher capacitance limits use to low-speed lines only; larger footprint incompatible with ultra-thin designs. | Select when board space allows and higher clamping voltage (10.5V @ 30A) is acceptable for 5V systems. |
| ESD5Z6.0T1G | SOD-523 package (1.3 × 0.85mm), 6.0V VRWM, 12A IPP, 100pF CT | Lower surge rating restricts use to non-critical I/O; insufficient for IEC 61000-4-2 ±30kV full compliance. | Select only for cost-sensitive, low-risk interfaces where 12A peak current suffices and 100pF capacitance is prioritized. |
Compared with SMAJ6.0A and ESD5Z6.0T1G, D6V3H1U2LP4-7B uniquely balances ultra-small size, ±30kV ESD robustness, and 200pF capacitance-making it optimal for space-constrained, high-reliability portable I/O protection where both speed and surge margin matter.

FAQ
What is the maximum clamping voltage at 30A for D6V3H1U2LP4-7B?
The maximum clamping voltage is 12.5V at 30A peak pulse current (8/20µs waveform), as specified in the Electrical Characteristics table. This value ensures protected circuits remain within safe operating voltage limits during worst-case ESD events, and is measured with defined test conditions per IEC 61000-4-2 Annex B.
Is D6V3H1U2LP4-7B suitable for bidirectional signal lines like USB D+/D−?
No - D6V3H1U2LP4-7B is unidirectional and intended for single-ended I/O lines referenced to ground. For differential or bidirectional interfaces, a pair of unidirectional devices or a dedicated bidirectional TVS (e.g., D5V0F4U2LP4-7B) must be used to ensure proper clamping in both polarities.
Does this TVS require a thermal pad or special PCB layout for heat dissipation?
No thermal pad is required - the X2-DFN1006-2 package relies on terminal conduction and PCB copper area for thermal management. Diodes specifies a standard FR-4 pad layout (available at diodes.com/package-outlines.html) that achieves 500°C/W RθJA; no internal thermal slug or exposed pad is present.
Can D6V3H1U2LP4-7B replace older DFN1006-2 TVS diodes like D6V0F2U2LP4-7B in existing designs?
Yes - it shares identical X2-DFN1006-2 packaging, pinout, and solder profile, but offers improved 6.5V VBR (vs. 6.0V) and tighter 200pF capacitance tolerance. Layout reuse is fully supported; verify system-level ESD performance due to the slightly higher clamping onset voltage.
