Product details
Overview
D15V0HA1U2LP-7B from Diodes Incorporated is a unidirectional transient voltage suppression (TVS) diode designed for ESD and surge protection on high-speed data lines. It features a 15.0V reverse working voltage, ±30kV IEC 61000-4-2 contact/air ESD rating, 20A peak pulse current (8/20µs), 95pF typical junction capacitance, and X1-DFN1006-2 (1.1mm × 0.7mm) package-ideal for USB 2.0, HDMI, and audio jack interfaces in smartphones.
For engineers reviewing the D15V0HA1U2LP-7B datasheet, D15V0HA1U2LP-7B pinout, D15V0HA1U2LP-7B application, or D15V0HA1U2LP-7B equivalent, key selection criteria include clamping voltage at 20A (23V), low-profile footprint compatibility with 0.4mm pitch layouts, thermal derating above 25°C, and compliance with IEC 61000-4-5 surge and RoHS 3/Green standards.
Technical Context
This TVS operates as a single-channel, unidirectional clamp between signal line and ground, triggered when reverse voltage exceeds 16.0V (min VBR). Its low 95pF capacitance ensures minimal signal integrity impact on 480Mbps USB 2.0 paths, while the 23V clamping voltage at 20A limits downstream IC stress during lightning-induced surges.
The device uses a planar silicon junction structure in a lead-free, halogen-free DFN package with NiPdAu-plated terminals. Thermal resistance is 500°C/W (J-A), requiring PCB copper area per Diodes' suggested pad layout to sustain 250mW continuous power dissipation at +25°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Working Voltage | 15.0V - Maximum DC or RMS signal voltage the device blocks without conduction |
| Breakdown Voltage (Min) | 16.0V @ 1mA - Threshold where TVS begins avalanche conduction during overvoltage events |
| Clamping Voltage (20A) | 23V @ 8/20µs - Peak voltage imposed on protected line during worst-case 20A surge |
| Junction Capacitance | 95pF @ 0V, 1MHz - Low enough to avoid signal attenuation in USB 2.0 and audio applications |
| ESD Rating | ±30kV air & contact - Meets highest IEC 61000-4-2 level for handheld device button/jack interfaces |
| Surge Rating | 20A peak pulse (8/20µs) - Withstands IEC 61000-4-5 Level 3 surge transients on external ports |
| Package | X1-DFN1006-2 - 1.1mm × 0.7mm × 0.5mm footprint, compatible with automated SMT placement |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Connected to protected signal line (e.g., USB D+, HDMI TMDS+); conducts to ground during overvoltage |
| Pin 2 | Cathode | Connected to system ground plane; provides low-inductance return path for surge current |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile | 0.50mm typical height - Enables use under mechanical shields and in slim bezel designs |
| ESD robustness | ±30kV contact/air - Eliminates need for secondary ESD protection in portable front-panel interfaces |
| Low capacitance | 95pF - Preserves signal rise time and eye diagram integrity on 480Mbps USB 2.0 links |
| Green compliance | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb) - Meets IPC-1752A Tier 2 reporting requirements |
Applications
| USB 2.0 Interface Protection | HDMI Connector ESD Guard |
|---|---|
Use Scenario: Protecting USB D+ and D− lines in smartphone charging ports against repeated plug/unplug ESD events. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed directly at connector, shunting ESD current to ground before it reaches USB transceiver. Use Value: Prevents latch-up or gate oxide damage in USB PHY ICs by limiting clamped voltage to ≤23V during ±30kV discharges. | Use Scenario: Shielding HDMI Type-A receptacle pins (TMDS+, TMDS−, CEC, HPD) in tablets from user-hand ESD. IC Role / Device Role / Timing Role: One D15V0HA1U2LP-7B per differential pair, mounted within 3mm of connector edge to minimize inductance. Use Value: Maintains 95pF capacitance to avoid degrading 1.65Gbps TMDS signal integrity while passing IEC 61000-4-2 testing. |
| Smartphone Audio Jack | Industrial Sensor Interface |
Use Scenario: ESD protection for 3.5mm TRRS headset jack mic and ground lines in mobile handsets. IC Role / Device Role / Timing Role: Bidirectional protection achieved using two unidirectional devices back-to-back; this part handles mic bias line polarity. Use Value: 15.0V VRWM allows compatibility with 2.8V mic bias rails while clamping transients below audio codec ABS MAX ratings. | Use Scenario: Surge protection for 4–20mA current-loop sensor inputs exposed to factory floor transients. IC Role / Device Role / Timing Role: Placed across input terminals ahead of op-amp conditioning stage to absorb 20A IEC 61000-4-5 surges. Use Value: 460W peak pulse power rating sustains 8/20µs surges without degradation, ensuring long-term reliability in harsh environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A-Q | DO-214AC package (4.5mm × 2.7mm), 15V VRWM, 23.1V VCL @ 20A, 100pF | Not suitable for space-constrained portable PCBs due to 6× larger footprint | Select when board area is unconstrained and higher surge energy handling (400W) is required |
| SP1003-010 | SOD-323 package (1.7mm × 1.25mm), 12V VRWM, 19.5V VCL @ 20A, 105pF | Lower VRWM limits use to sub-12V signal rails; higher capacitance affects >200Mbps signals | Select only for 3.3V/5V logic lines where tighter clamping voltage justifies reduced speed margin |
Compared with SMAJ15A-Q and SP1003-010, D15V0HA1U2LP-7B uniquely balances ultra-small footprint (1.1mm × 0.7mm), 15V VRWM compatibility with common bias rails, and 95pF capacitance-making it optimal for high-density USB/audio/HDMI protection where board space and signal integrity are co-constrained.

FAQ
What is the maximum operating temperature for D15V0HA1U2LP-7B?
The device supports continuous operation from –55°C to +150°C ambient. Derating begins at +25°C: power dissipation drops linearly to zero at +150°C, per Figure 1 in DS41799. At +85°C ambient, maximum allowable continuous power is 125mW.
Can D15V0HA1U2LP-7B protect bidirectional signal lines like USB D+?
No-it is unidirectional and must be used in pairs (anode-to-line/cathode-to-ground and cathode-to-line/anode-to-ground) for true bidirectional protection. For native bidirectional operation, consider Diodes' D12V0UA1U2LP-7B (12V symmetric clamping).
Is the X1-DFN1006-2 package compatible with standard reflow profiles?
Yes-the device is rated for Moisture Sensitivity Level 1 (per J-STD-020) and withstands standard Pb-free reflow profiles (peak 260°C, 30 sec max). The NiPdAu terminal finish ensures reliable solder wetting with SAC305 paste.
How does its 95pF capacitance affect USB 2.0 signal integrity?
At 95pF, insertion loss at 240MHz (USB 2.0 fundamental) is <0.5dB and eye diagram jitter increase is <1%-well within USB-IF compliance margins. Layout best practices (short traces, ground pour under device) maintain this performance.
