Product details
Overview
D15V0H1U2LP-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 15 V reverse working voltage, 16 V minimum breakdown voltage, 22 V clamping voltage at 5 A, 70 pF typical junction capacitance, and ±30 kV IEC 61000-4-2 contact/air ESD rating - deployed on USB, HDMI, and audio interfaces in smartphones and digital cameras.
For engineers reviewing the D15V0H1U2LP-7B datasheet, D15V0H1U2LP-7B pinout, D15V0H1U2LP-7B application, or D15V0H1U2LP-7B equivalent, key selection criteria include low-capacitance signal integrity preservation, ultra-small X1-DFN1006-2 footprint compatibility with tight board space, and validated ±30 kV ESD robustness for consumer-grade handheld devices.
Technical Context
This TVS operates as a single-channel unidirectional clamp between I/O and ground, triggered by overvoltage transients exceeding its 16 V breakdown threshold. Its low 70 pF capacitance minimizes signal distortion on high-frequency lines up to 100 MHz, while the 22 V clamping voltage at 5 A ensures downstream ICs remain within safe operating limits during ESD events.
The device uses a planar silicon junction structure in a lead-free, halogen-free X1-DFN1006-2 package with NiPdAu-plated terminals. Thermal resistance is 500 °C/W, and power derating begins above 25 °C ambient, supporting reliable operation in compact, thermally constrained portable enclosures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Working Voltage | 15.0 V - Maximum continuous DC voltage applied without conduction; sets upper limit for protected signal swing. |
| Breakdown Voltage (Min) | 16 V - Voltage at which device enters avalanche conduction; ensures reliable triggering before system damage. |
| Clamping Voltage (5 A) | 22 V - Peak voltage seen by protected circuit during 5 A 8/20 µs surge; defines worst-case stress on downstream IC. |
| Junction Capacitance | 70 pF @ 0 V, 1 MHz - Low enough to avoid signal attenuation or timing skew on USB 2.0 or audio paths. |
| ESD Rating | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - Meets highest consumer-grade ESD immunity requirement for handheld interfaces. |
| Peak Pulse Current | 12 A @ 8/20 µs - Sustains industry-standard lightning/surge test waveform without failure. |
| Package | X1-DFN1006-2 - 1.08 mm × 0.68 mm footprint with 0.53 mm max height; enables routing under connectors in ultra-thin PCBs. |
Pinout & Package
Supplied in the X1-DFN1006-2 surface-mount package: 0.53 mm maximum height, 1.08 mm × 0.68 mm body, side-wall plated terminals, NiPdAu finish, JEDEC-compliant moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Connected to protected I/O line; forward-biased during negative transients (not used in unidirectional configuration). |
| Pin 2 | Cathode | Connected to system ground; conducts avalanche current during positive ESD events above VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile | 0.53 mm max height - fits beneath stacked FPC connectors and under bezel-mounted buttons in <8 mm thick handsets. |
| IEC 61000-4-2 certified ESD protection | ±30 kV contact/air - eliminates need for external ESD testing waivers in CE/FCC certification for consumer devices. |
| Low channel capacitance | 70 pF typical - preserves signal rise time and eye diagram integrity on 480 Mbps USB 2.0 differential pairs. |
| Green, RoHS-compliant construction | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) - satisfies EU EcoDesign and China RoHS II requirements. |
Applications
| USB 2.0 Data Lines | HDMI Interface Protection |
|---|---|
Use Scenario: ESD protection for D+ and D− pins on smartphone USB ports exposed to frequent plug/unplug cycles. IC Role / Device Role / Timing Role: Unidirectional TVS clamp referenced to ground, activated only during positive surges above 16 V. Use Value: 70 pF capacitance avoids USB 2.0 eye diagram closure; ±30 kV rating prevents interface lockup during user-handling events. | Use Scenario: Transient suppression on TMDS clock and data channels in portable media players with mini-HDMI outputs. IC Role / Device Role / Timing Role: Single-channel I/O-to-ground clamp placed immediately adjacent to HDMI connector pins. Use Value: 22 V clamping at 5 A keeps TMDS receiver input within 0–3.3 V common-mode range during ESD discharge. |
| Smartphone Audio Jacks | Digital Camera SD Card Interfaces |
Use Scenario: Protecting microphone and headset detection lines in 3.5 mm TRRS jacks subject to pocket-induced static discharge. IC Role / Device Role / Timing Role: Ground-referenced unidirectional clamp on biased analog audio paths. Use Value: 15 V VRWM allows full compatibility with 1.8 V/3.3 V audio codec bias rails without leakage-induced noise. | Use Scenario: ESD hardening of SDIO command and data lines in compact digital cameras with sliding SD card doors. IC Role / Device Role / Timing Role: Per-line TVS on CMD, CLK, and DAT[0:3] traces routed near mechanical openings. Use Value: X1-DFN1006-2 footprint enables placement within 2 mm of SD card connector, minimizing stub inductance and clamping delay. |
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 (4.5 mm × 3.3 mm), 15 V VRWM, 24.4 V clamping at 5 A, 150 pF capacitance | Higher capacitance and larger footprint - unsuitable for high-speed mobile interfaces but acceptable for industrial control I/O. | Select when board space permits and signal bandwidth <10 MHz; avoid for USB/HDMI. |
| TPD2E001DRYR | 2-channel bidirectional TVS in X2SON-6, 5.5 V VRWM, 12 V clamping, 12 pF/channel | Lower voltage rating and bidirectional behavior - intended for low-voltage data lines like I²C, not 15 V-tolerant I/O. | Choose only for sub-6 V logic interfaces; incompatible with 15 V signal swing requirements. |
Compared with SMAJ15A-Q and TPD2E001DRYR, D15V0H1U2LP-7B uniquely balances 15 V operating margin, 70 pF signal loading, and 1.08 mm × 0.68 mm size - making it the sole fit for space-constrained, high-speed, 15 V-rated portable data lines requiring ±30 kV ESD immunity.

FAQ
What is the maximum operating temperature for D15V0H1U2LP-7B?
The device supports continuous operation from −65 °C to +150 °C junction temperature. Derating begins at +25 °C ambient: power dissipation drops linearly to zero at +150 °C, per Figure 1 in DS38851. PCB layout using 2 oz copper pads per Diodes' recommended footprint is required to achieve rated thermal resistance of 500 °C/W.
Can D15V0H1U2LP-7B be used for bidirectional signal lines?
No - D15V0H1U2LP-7B is strictly unidirectional and must be oriented with cathode to ground. It provides no protection against negative transients on the I/O line. For bidirectional protection (e.g., USB D+/D−), two devices in back-to-back configuration or a dedicated bidirectional TVS like SP1001-01UTG are required.
Is the marking 'MQ' on the device body electrically significant?
No - 'MQ' is the product type marking code per Diodes' internal scheme and indicates D15V0H1U2LP-7B. It has no electrical function. The bar adjacent to Pin 1 denotes cathode orientation; correct placement requires alignment of this bar with the PCB's designated cathode pad (ground net), verified via bottom-view schematic in DS38851 page 2.
Does D15V0H1U2LP-7B require external series impedance for optimal clamping?
No external resistor is required for basic ESD protection. However, adding a 0–10 Ω series resistor between the protected I/O and the TVS anode can reduce peak current stress during 12 A surges and improve clamping consistency - particularly beneficial in designs where PCB trace inductance exceeds 10 nH. Diodes does not specify or recommend such resistors in standard use.
