Product details
Overview
D7V0H1U2LP-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 delivers 7.5V minimum breakdown voltage, ±30kV IEC 61000-4-2 contact/air discharge immunity, and 150pF typical junction capacitance in an ultra-compact X1-DFN1006-2 package - deployed on USB, audio, and camera interfaces in smartphones and wearables.
For engineers reviewing the D7V0H1U2LP-7B datasheet, D7V0H1U2LP-7B pinout, D7V0H1U2LP-7B application, or D7V0H1U2LP-7B equivalent, key selection criteria include clamping voltage at 24A (14.4V), low-profile footprint (1.08 × 0.68 mm), thermal resistance (500°C/W), RoHS/Green compliance, and single-channel unidirectional topology for signal-line protection.
Technical Context
This TVS diode operates as a unidirectional clamp between I/O and ground, activating above 7.5V reverse breakdown to shunt ESD transients away from sensitive ICs. Its 150pF capacitance and 10.6V clamping at 5A ensure minimal signal distortion on high-speed lines like USB 2.0 and MIPI D-PHY.
The device uses silicon avalanche structure with NiPdAu-plated copper leadframe and meets J-STD-020 Level 1 moisture sensitivity. Thermal derating follows a linear curve down to zero power at +150°C ambient, with 250mW steady-state dissipation on standard FR-4 PCB layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 7.5V min @ 1mA - ensures reliable conduction onset before damage to 3.3V/5V interface ICs |
| Clamping Voltage (VCL) | 14.4V max @ 24A, 8/20µs - limits stress on protected IC during worst-case ESD surge |
| Junction Capacitance (CT) | 150pF typ @ 0V, 1MHz - preserves signal integrity on 480Mbps USB 2.0 and 1Gbps MIPI lanes |
| ESD Rating | ±30kV air & contact per IEC 61000-4-2 - exceeds industrial and consumer immunity requirements |
| Package | X1-DFN1006-2 (1.08 × 0.68 × 0.53 mm) - enables placement adjacent to connectors without board area penalty |
| Thermal Resistance (RθJA) | 500°C/W - defines safe continuous power limit (250mW) on standard 2oz FR-4 pad layout |
Pinout & Package
Package: X1-DFN1006-2 - ultra-thin, two-terminal, bottom-side cathode-marked surface-mount package with NiPdAu terminals and UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Connected to protected I/O line; forward-biased during normal operation, blocks reverse leakage (<1µA @ 7V) |
| Pin 2 | Cathode | Connected to system ground; provides low-impedance path to shunt ESD current during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|

| IEC 61000-4-2 certified ESD protection | ±30kV contact/air - eliminates need for external ESD test fixtures during system validation |
| Lead-free & Green compliant | No intentionally added lead, Br/Cl <900ppm, Sb <1000ppm - satisfies global environmental compliance mandates |
| Moisture sensitivity level | Level 1 per J-STD-020 - allows indefinite floor life without dry pack or baking prior to reflow |
Applications
| Smartphone Front Camera Interface | USB 2.0 Data Lines |
|---|---|
Use Scenario: Protecting MIPI CSI-2 differential pairs between image sensor and application processor from handling ESD. IC Role / Device Role / Timing Role: Unidirectional TVS placed directly at connector side to clamp fast-rising ESD pulses before reaching serializer IC.

Use Value: X1-DFN1006-2 footprint fits tight spacing near flex ZIF connectors without requiring additional keep-out area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.0A | DO-214AC package (4.5 × 2.7 mm), 7.0V VRWM, 12.5V VCL@24A, 350pF | Higher capacitance and larger footprint - unsuitable for space-constrained high-speed interfaces | Select only when board space permits and lower clamping voltage outweighs size/capacitance penalties |
| SP1001-01UTG | SOD-523 package (1.3 × 0.85 mm), 5.5V VRWM, 12.5V VCL@5A, 0.6pF | Lower working voltage and sub-pF capacitance - better for RF/analog but insufficient for 7V logic rails | Prefer for RF front-end or low-voltage analog sensors; not drop-in for 3.3V/5V digital I/O protection |
Compared with SMAJ7.0A and SP1001-01UTG, D7V0H1U2LP-7B uniquely balances 7.5V breakdown, 150pF capacitance, and 1.08 × 0.68 mm footprint - making it optimal for compact, high-speed digital interfaces where both voltage margin and signal fidelity matter.

FAQ
What is the polarity configuration of D7V0H1U2LP-7B?
D7V0H1U2LP-7B is a unidirectional TVS diode with anode (Pin 1) and cathode (Pin 2) terminals. It conducts only when the anode is driven positive relative to cathode - ideal for protecting grounded-signal lines such as USB D+ or MIPI data pairs. The cathode side is marked by a bar on the package bottom view.
Does D7V0H1U2LP-7B require series impedance for optimal ESD performance?
No external series impedance is required for basic ESD clamping functionality. However, placing a small ferrite bead (e.g., 60Ω @ 100MHz) between the TVS and protected IC can improve high-frequency filtering without affecting DC bias. Layout best practice requires shortest possible trace from I/O pin to TVS anode and direct ground connection to cathode.
Can D7V0H1U2LP-7B be used on bidirectional signal lines like I²C?
No - D7V0H1U2LP-7B is unidirectional and will conduct during negative excursions on bidirectional lines, disrupting normal signaling. For I²C or other bidirectional interfaces, a bidirectional TVS such as D7V0F1U2LP-7B (same package, symmetrical clamping) must be selected instead.
What is the maximum allowable PCB trace length between D7V0H1U2LP-7B and the protected IC?
To maintain effective ESD suppression, the trace from the TVS anode to the protected IC pin should not exceed 3 mm. Longer traces add inductance that degrades clamping response; the TVS cathode must connect directly to a solid ground plane with minimal via count. Diodes' recommended pad layout (X1-DFN1006-2) specifies 0.3mm thermal relief gaps to balance solderability and thermal performance.
