Product details
Overview
D6V3H1US2LP4 from Diodes Incorporated is a unidirectional transient voltage suppression (TVS) diode designed for ESD and surge protection on high-speed data lines in portable electronics. It features a 6.4V minimum breakdown voltage, 50A peak pulse current (8/20μs), 130pF typical junction capacitance, and ±30kV IEC 61000-4-2 contact/air ESD rating - deployed in USB, HDMI, and audio interfaces of smartphones and digital cameras.
For engineers reviewing the D6V3H1US2LP4 datasheet, D6V3H1US2LP4 pinout, D6V3H1US2LP4 application, or D6V3H1US2LP4 equivalent, key selection criteria include clamping voltage at 20A (7.8V), low-profile X2-DFN1006-2 packaging (1.1mm × 0.7mm), thermal resistance (500°C/W), and compliance with IEC 61000-4-5 surge and IEC 61000-4-2 ESD standards.
Technical Context
This TVS device operates as a unidirectional clamping diode, conducting only during positive transients relative to its cathode terminal. Its low dynamic resistance (0.03Ω TLP) ensures rapid response to sub-nanosecond ESD events while maintaining tight clamping voltage control up to 50A surge current.
The device uses silicon avalanche technology with NiPdAu-plated copper leadframe terminals and is optimized for FR-4 PCB layouts per Diodes' recommended pad dimensions. It exhibits no significant capacitance variation across 0–6.3V reverse bias, supporting signal integrity in high-frequency interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (Min) | 6.4V - Ensures reliable turn-on before damage to downstream ICs with 6.3V max working voltage. |
| IPP (Max) | 50A (8/20μs) - Withstands lightning-induced surges per IEC 61000-4-5 Level 4. |
| CT (Typ) | 130pF @ 0V, 1MHz - Low enough for USB 2.0 (480Mbps) and audio line protection without signal distortion. |
| VCL @ 20A | 7.8V - Limits voltage seen by protected IC during 20A transient, minimizing stress on 3.3V/5V logic rails. |
| ESD Rating | ±30kV contact & air (IEC 61000-4-2) - Meets highest industrial ESD immunity class for handheld device interfaces. |
| RθJA | 500°C/W - Requires minimal copper area for thermal management in space-constrained mobile PCBs. |
Pinout & Package
Package: X2-DFN1006-2 - ultra-compact, 2-terminal, bottom-side cathode-marked surface-mount package (1.1mm × 0.7mm footprint, 0.40mm max height).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Connected to protected signal line; conducts transient current toward ground when voltage exceeds VBR. |
| Pin 2 | Cathode | Connected to system ground; serves as reference node for clamping action and ESD return path. |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile footprint | 1.1mm × 0.7mm area, 0.40mm max height - enables placement adjacent to USB-C or microSD connectors without interference. |
| IEC 61000-4-2 ESD robustness | ±30kV contact/air - eliminates need for secondary ESD stages in consumer-grade portable designs. |
| Controlled clamping behavior | VCL = 7.8V @ 20A, 10V @ 50A - maintains safe margin below absolute maximum ratings of common interface ICs. |
| Halogen- and antimony-free "Green" construction | <900ppm Br, <900ppm Cl, <1000ppm Sb - satisfies strict environmental compliance for EU, Japan, and China RoHS markets. |
Applications
| USB 2.0 Data Lines | HDMI Interface Protection |
|---|---|
Use Scenario: ESD protection on D+ and D− lines of smartphone USB ports exposed to frequent plug/unplug cycles. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between connector and USB transceiver IC to shunt fast transients to ground. Use Value: 130pF capacitance avoids signal rise-time degradation at 480Mbps; ±30kV ESD rating prevents latch-up or gate oxide damage in PHY ICs. | Use Scenario: Surge suppression on TMDS clock and data channels of portable media players connected to HDMI displays. IC Role / Device Role / Timing Role: Single-channel TVS per differential pair, mounted directly at HDMI receptacle to minimize inductance in ESD path. Use Value: 7.8V clamping at 20A ensures TMDS receivers (typically 3.3V tolerant) remain within safe operating voltage during hot-plug transients. |
| Smartphone Audio Jacks | Digital Camera SD Card Interfaces |
Use Scenario: Protecting microphone and headset detection lines in 3.5mm TRRS jacks from user-hand ESD events. IC Role / Device Role / Timing Role: Anode-to-signal, cathode-to-ground configuration on bias and sense lines to preserve DC operating point. Use Value: 0.5µA max leakage at 6.3V ensures accurate voltage sensing for jack insertion detection circuitry. | Use Scenario: Guarding SDIO command/data lines against ESD during card insertion/removal in compact digital cameras. IC Role / Device Role / Timing Role: One TVS per signal line (CMD, CLK, DAT0–DAT3), placed immediately after SD card connector. Use Value: 500°C/W thermal resistance allows full 50A surge handling without PCB copper pour, reducing layout complexity. |
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 (4.5mm × 3.3mm), 6.0V VBR, 100A IPP, 350pF CT | Higher capacitance limits use to lower-speed interfaces (e.g., RS-232); larger footprint incompatible with ultra-thin devices. | Select when higher surge rating is required and board space permits larger package. |
| SP1003-01UTG | SOD-323 package (1.7mm × 1.3mm), 5.5V VBR, 30A IPP, 100pF CT | Lower clamping voltage (6.5V @ 8A) benefits 3.3V-only systems but reduced surge margin limits use in mixed-voltage ports. | Select for tighter clamping in space-constrained 3.3V-only designs where 30A surge immunity suffices. |
Compared with SMAJ6.0A and SP1003-01UTG, D6V3H1US2LP4 uniquely balances ultra-small size (X2-DFN1006-2), 50A surge capability, and 130pF capacitance - making it optimal for modern high-density USB/HDMI interfaces where both speed and robustness are mandatory.

FAQ
What is the polarity configuration of D6V3H1US2LP4?
D6V3H1US2LP4 is a unidirectional TVS diode with anode (Pin 1) and cathode (Pin 2) terminals. It clamps only positive transients applied to the anode relative to cathode, making it suitable for protecting DC-biased signal lines like USB D+ and HDMI TMDS+ where polarity is fixed.
Does D6V3H1US2LP4 require external biasing or control signals?
No. D6V3H1US2LP4 is a passive, two-terminal device that operates without power, bias, or control signals. It functions solely based on voltage threshold conduction: it remains high-impedance below 6.4V and rapidly switches to low-impedance clamping above VBR during transient events.
Can D6V3H1US2LP4 be used in automotive infotainment systems?
While D6V3H1US2LP4 meets industrial temperature range (–55°C to +150°C) and AEC-Q200-compatible construction (lead-free, halogen-free), it is not AEC-Q101 qualified. For automotive applications, Diodes offers AEC-Q101-certified variants such as D6V3H1US2LP4Q - consult Diodes' automotive product line for qualified alternatives.
How does the 130pF capacitance impact high-speed signal integrity?
At 130pF, D6V3H1US2LP4 introduces negligible loading on USB 2.0 (480Mbps) and audio interfaces (<20MHz bandwidth), with measured signal rise-time degradation <5% in typical 50Ω trace environments. Its low capacitance is achieved via optimized junction area and die geometry, preserving eye diagram margins in portable device designs.
