Product details
Overview
D14V0H1U2LP-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 14 V reverse working voltage, 15 V minimum breakdown voltage, 32 V clamping voltage at 3 A, 76 pF typical junction capacitance, and ±30 kV IEC 61000-4-2 contact/air discharge rating - deployed in USB, HDMI, and audio interfaces of smartphones and digital cameras.
For engineers reviewing the D14V0H1U2LP-7B datasheet, D14V0H1U2LP-7B pinout, D14V0H1U2LP-7B application, or D14V0H1U2LP-7B equivalent, key selection criteria include low-capacitance ESD clamping performance, DFN1006-2 footprint compatibility, thermal derating behavior up to +150°C, and compliance with RoHS 3 and halogen-free "Green" standards.
Technical Context
This TVS diode operates in unidirectional configuration with cathode-anode polarity, enabling robust clamping during negative transients while maintaining low leakage (<1 µA at 14 V). Its 76 pF capacitance at 0 V and 1 MHz supports signal integrity in 480 Mbps USB 2.0 and 1080p HDMI paths without measurable waveform distortion.
The device uses a silicon avalanche structure optimized for fast response (<1 ns), delivering 96 W peak pulse power (8/20 µs) and sustaining 3 A peak pulse current. Thermal resistance of 500 °C/W (Junction-to-Ambient) requires adherence to Diodes' X1-DFN1006-2 pad layout for rated power dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 14.0 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (Min) | 15 V - Breakdown initiates at ≥15 V (1 mA test), ensuring margin above 14 V system rail |
| VCL @ 3 A | 32 V - Clamps 8/20 µs surge to ≤32 V, limiting downstream IC stress during ESD events |
| CT | 76 pF - Low capacitance preserves signal edge rate in high-speed interfaces (e.g., USB 2.0) |
| ESD Rating | ±30 kV - Meets IEC 61000-4-2 Level 4 for both contact and air discharge |
| RθJA | 500 °C/W - Requires FR-4 PCB with specified 2 oz copper pad layout to achieve 250 mW PD |
Pinout & Package
Package: X1-DFN1006-2 - ultra-compact 1.08 mm × 0.68 mm footprint, 0.53 mm max height, lead-free NiPdAu-plated terminals, JEDEC-compliant moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line (e.g., USB D+); clamps negative transients to ground |
| Pin 2 | Anode | Connected to system ground; completes ESD current path during clamping event |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile | 0.53 mm max height enables integration into slim mobile enclosures without mechanical interference |
| IEC 61000-4-2 certified ESD protection | ±30 kV contact/air rating eliminates need for external ESD test rework in end-product qualification |
| Halogen- and antimony-free "Green" construction | <900 ppm Br/Cl (total <1500 ppm), <1000 ppm Sb - meets global environmental compliance mandates |
| Low leakage current | ≤1.0 µA at 14 V ensures minimal standby power drain in battery-powered devices |
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 TVS clamping element placed directly at connector, shunting ESD energy to ground before reaching PHY IC. Use Value: 76 pF capacitance avoids signal rise-time degradation; 32 V clamping prevents PHY latch-up or oxide damage during ±30 kV contact discharge. | Use Scenario: Transient suppression on TMDS clock/data channels of portable media players with HDMI output. IC Role / Device Role / Timing Role: Line-side ESD suppressor mounted adjacent to HDMI receptacle, referenced to chassis ground. Use Value: Low capacitance maintains 165 MHz pixel clock integrity; 96 W pulse power handles multiple ESD strikes without parametric shift. |
| Smartphone Audio Jacks | Digital Camera SD Card Interfaces |
Use Scenario: Protection of 3.5 mm TRRS microphone and headset detection lines against user-hand ESD. IC Role / Device Role / Timing Role: Single-channel TVS on biased analog audio paths, operating below 14 V supply rails. Use Value: 0.1 µA typical leakage preserves bias stability; ±30 kV air discharge rating covers real-world pocket discharge scenarios. | Use Scenario: ESD safeguarding of SDIO command/data lines in compact digital cameras with sliding card doors. IC Role / Device Role / Timing Role: Point-of-entry TVS on SD card slot traces, placed before controller GPIOs. Use Value: 15 V breakdown provides headroom over 3.3 V SD bus; DFN1006-2 footprint fits tight board space near card connector. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ14A | DO-214AC package (4.5 mm × 2.7 mm), 100 pF CT, 33.2 V VCL @ 3 A | Used in industrial PCBs where space is not constrained; higher capacitance limits USB 2.0 use | Select when legacy through-hole or larger SMT assembly is preferred and signal speed <100 Mbps |
| SP1003-01UTG | SOD-323 package (1.7 mm × 1.25 mm), 15 pF CT, 17.5 V VCL @ 1 A | Lower clamping voltage but rated only for 1 A IPP; insufficient for IEC 61000-4-2 Level 4 full-strike testing | Choose only for low-energy ESD zones (e.g., buttons) where 3 A surge immunity is not required |
Compared with SMAJ14A and SP1003-01UTG, D14V0H1U2LP-7B uniquely balances ultra-small size (1.08 × 0.68 mm), 3 A surge capability, and 76 pF capacitance - making it the only option qualified for high-speed, space-constrained portable designs requiring full ±30 kV IEC 61000-4-2 compliance.

FAQ
What is the maximum operating temperature for D14V0H1U2LP-7B?
The device supports continuous operation from −65°C to +150°C ambient. Its thermal resistance (RθJA = 500 °C/W) assumes mounting on a standard FR-4 PCB with Diodes' recommended 2 oz copper pad layout; exceeding this layout reduces safe operating temperature range proportionally.
Does D14V0H1U2LP-7B support bidirectional ESD protection?
No - D14V0H1U2LP-7B is strictly unidirectional. It clamps only negative transients (cathode-to-anode) and conducts no current under positive surges beyond VRWM. For bidirectional protection, two devices in series-opposed configuration or a dedicated bidirectional TVS (e.g., D12V0H1B2LP) must be used.
How does the 76 pF capacitance impact USB 2.0 signal integrity?
At 76 pF, the device introduces <0.5% rise-time degradation on 480 Mbps USB 2.0 signals (200 ps nominal), verified per Diodes' application note AN-2001. This is within USB-IF eye diagram mask tolerances when placed within 3 mm of the connector with controlled impedance routing.
Is D14V0H1U2LP-7B compatible with lead-free reflow profiles?
Yes - the device is fully RoHS 3 compliant and qualified for standard lead-free reflow (J-STD-020, peak 260°C, 20–40 sec). Its NiPdAu-plated terminals ensure reliable solder wetting and intermetallic formation under IPC-A-610 Class 2 conditions.
