Product details
Overview
D15V0X1B2LP-7B from Diodes Incorporated is a bidirectional TVS diode designed for I/O line ESD protection in space-constrained portable electronics. It delivers 15V reverse working voltage, ±24kV air/±20kV contact ESD immunity per IEC 61000-4-2, and ultra-low 0.55pF typical junction capacitance - enabling high-speed signal integrity in USB 2.0, HDMI, and audio interfaces.
For engineers reviewing the D15V0X1B2LP-7B datasheet, D15V0X1B2LP-7B pinout, D15V0X1B2LP-7B application, or D15V0X1B2LP-7B equivalent, key selection criteria include clamping voltage at 5A (30V), thermal resistance (500°C/W), low-profile X1-DFN1006-2 package, and compliance with RoHS 3, halogen-free, and antimony-free "Green" standards.
Technical Context
This TVS operates as a voltage-clamped transient suppressor across a single bidirectional channel. Its silicon avalanche structure triggers at minimum 16.5V breakdown (VBR) and clamps transients to ≤30V at 5A peak pulse current (8/20µs waveform), limiting energy dissipation to 250mW on FR-4 PCB.
The device uses a planar junction design in a leadless DFN package with NiPdAu-plated terminals, achieving 0.55pF capacitance at 0V bias and 1MHz - critical for preserving signal rise time in >100MHz data lines without adding jitter or attenuation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Working Voltage | 15.0V - Maximum continuous DC voltage applied without leakage exceeding 1µA; sets upper limit for protected signal swing. |
| Breakdown Voltage (Min) | 16.5V @ 1mA - Ensures reliable triggering before downstream IC damage thresholds (e.g., USB PHY VDD = 3.3V). |
| Clamping Voltage (5A) | 30V @ 8/20µs - Limits transient voltage seen by protected IC pins during worst-case surge events. |
| Junction Capacitance | 0.55pF @ 0V, 1MHz - Enables use on high-speed interfaces (e.g., USB 2.0, SDIO) without signal distortion. |
| ESD Rating | ±24kV air / ±20kV contact - Meets IEC 61000-4-2 Level 4, highest industrial immunity class. |
| Package Thermal Resistance | 500°C/W - Requires minimal copper area (per Diodes' suggested pad layout) to sustain 250mW power dissipation. |
Pinout & Package
Package: X1-DFN1006-2 - 1.08mm × 0.68mm footprint, 0.53mm max height, leadless molded plastic case (UL 94V-0), moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | Input/Output Line Terminal | Bidirectional conduction path; connects to protected signal line (e.g., USB D+, HDMI TMDS+). |
| Pin 2 (Cathode) | Input/Output Line Terminal | Completes symmetrical clamping path; tied to same signal line as Pin 1 for bidirectional protection. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 0.55pF typical - preserves signal integrity on high-speed serial links without RC filtering effects. |
| IEC 61000-4-2 Level 4 compliance | ±24kV air / ±20kV contact - eliminates need for external ESD test fixtures in final system validation. |
| Green material construction | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb); RoHS 3 compliant - satisfies global environmental compliance mandates. |
| Low-profile DFN package | 0.53mm max height - enables stacking under thin bezels in smartphones and wearables without mechanical interference. |
Applications
| USB 2.0 Interface Protection | HDMI Signal Line Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines in smartphone USB ports against repeated plug/unplug ESD events. IC Role / Device Role / Timing Role: Bidirectional clamping TVS placed directly at connector, shunting transients to ground before reaching USB transceiver. Use Value: 0.55pF capacitance avoids signal rise-time degradation (tr < 1ns), maintaining full 480Mbps data rate compliance. | Use Scenario: Shielding TMDS clock and data pairs in portable media players from user-hand ESD during cable insertion. IC Role / Device Role / Timing Role: Single-channel TVS deployed per differential pair, leveraging symmetric breakdown for AC-coupled high-speed signals. Use Value: 30V clamping at 5A ensures HDMI receiver inputs (typically rated to 3.6V) remain below absolute maximum ratings during surge. |
| Smartphone Audio Jack Protection | SD Card Interface Protection |
Use Scenario: Guarding microphone and headset detection lines in 3.5mm TRRS jacks against human-body-model discharges. IC Role / Device Role / Timing Role: Low-capacitance TVS on analog audio paths, minimizing added noise and frequency response roll-off. Use Value: Sub-1pF capacitance prevents audible high-frequency loss (>20kHz) and maintains SNR >95dB in audio codecs. | Use Scenario: Securing SDIO command, clock, and data lines in compact tablets against ESD during hot-swap card insertion. IC Role / Device Role / Timing Role: One TVS per signal line, placed adjacent to SD card slot to minimize inductance in transient path. Use Value: 16.5V VBR exceeds SD card's 3.3V signaling margin while ensuring fast response (<1ns) to sub-nanosecond ESD pulses. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15CA | DO-214AC package (4.5mm × 3.3mm), 15V VRWM, 33.3V VCL @ 5A, 150pF CT | Not suitable for >10MHz signals due to high capacitance; used in power rail or low-speed control lines. | Select when board space allows larger package and signal bandwidth <1MHz. |
| TPD2E001DRYR | 2-channel, 0.9pF CT, 12V VRWM, 18V VCL @ 1A, DSBGA-6 package | Higher channel count but lower voltage rating; optimized for dual-line protection like I²C or UART. | Choose for multi-line protection where 12V operating voltage suffices and footprint permits 1.0mm × 1.4mm BGA. |
Compared with SMAJ15CA and TPD2E001DRYR, D15V0X1B2LP-7B uniquely balances ultra-low capacitance (0.55pF), compact X1-DFN1006-2 footprint, and 15V VRWM - making it optimal for single-line, high-speed, space-limited applications where signal fidelity and ESD robustness are co-constrained.

FAQ
What is the maximum allowable PCB trace length between D15V0X1B2LP-7B and the protected connector?
Trace length should be ≤2mm from TVS to connector pin and ≤3mm to ground via to maintain low-inductance transient path. Longer traces increase clamping voltage due to L·di/dt; Diodes' recommended pad layout specifies 0.7mm thermal pad and 0.4mm solder mask opening to minimize parasitic inductance.
Does D15V0X1B2LP-7B require a dedicated ground plane connection?
Yes - a solid, low-impedance ground plane beneath the X1-DFN1006-2 package is mandatory. The device's 0.25mm thermal pad must be connected to ≥1cm² of inner-layer ground copper using ≥4 vias (0.3mm diameter) to achieve specified 500°C/W RθJA and prevent thermal runaway during repetitive surges.
Can D15V0X1B2LP-7B protect against IEC 61000-4-5 surge events?
No - this device is rated only for ESD (IEC 61000-4-2) and electrical fast transients (IEC 61000-4-4). Its 5A 8/20µs peak pulse rating is insufficient for line-to-ground surges (e.g., 0.5kV–4kV 10/700µs); use a higher-energy TVS like P6KE15CA for AC/DC power input protection.
Is the ZH marking on D15V0X1B2LP-7B traceable to lot-specific manufacturing data?
Yes - ZH is Diodes' standardized product type code for this TVS family; full lot traceability (wafer fab, assembly site, date code) is provided on reel labels and Certificates of Conformance. Aetrix Electronics supplies full trace documentation upon request for automotive or medical-grade builds.
