Product details
Overview
D5V0Q1B2LP3-7 from Diodes Incorporated is a bidirectional TVS diode designed for ESD protection of high-speed data lines in portable electronics. It features a 5.5V reverse standoff voltage, 6pF typical channel capacitance, ±15kV contact/±17kV air ESD immunity per IEC 61000-4-2, and a compact X3-DFN0603-2 package (0.6mm × 0.3mm). It is deployed in USB, HDMI, and audio interface paths of smartphones and digital cameras.
For engineers reviewing the D5V0Q1B2LP3-7 datasheet, D5V0Q1B2LP3-7 pinout, D5V0Q1B2LP3-7 application, or D5V0Q1B2LP3-7 equivalent, key selection criteria include clamping voltage at 3A (≤11.0V), low leakage (<100nA at 5V), thermal resistance (500°C/W), and compatibility with high-density PCB layouts requiring sub-0.3mm profile components.
Technical Context
This TVS operates as a bidirectional transient suppressor across a single channel, leveraging avalanche breakdown to clamp fast-rising ESD transients while maintaining minimal signal distortion. Its low 6pF input capacitance ensures integrity of >100MHz digital signals such as USB 2.0 and I²C bus lines.
The device uses a silicon planar construction with matte tin–plated copper leadframe and meets IEC 61000-4-2 Level 4 requirements without external filtering. Its 0.3mm height and 0.6mm × 0.3mm footprint enable placement directly at connector entry points on space-constrained PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5.5V - Maximum continuous operating voltage before conduction begins; defines safe working range for 5V logic interfaces. |
| Breakdown Voltage (VBR) | 6.0–8.0V @ 1mA - Ensures reliable triggering during ESD events while avoiding false trips under normal bias. |
| Clamping Voltage (IPP = 3A) | ≤11.0V - Limits peak voltage seen by protected IC during worst-case 8/20µs surge, safeguarding 5V-tolerant inputs. |
| Channel Capacitance (CT) | 6pF @ 0V, 1MHz - Enables use on high-speed lines (e.g., USB 2.0, SDIO) without signal rise-time degradation. |
| ESD Withstand (IEC 61000-4-2) | ±15kV contact / ±17kV air - Meets industrial and consumer end-equipment immunity requirements without additional shielding. |
| Power Dissipation | 250mW - Sustains short-duration surges without thermal runaway when mounted per recommended FR-4 pad layout. |
Pinout & Package
Package: X3-DFN0603-2 - ultra-compact, leadless, 2-terminal surface-mount package measuring 0.6mm × 0.3mm × 0.3mm, with exposed copper pads for thermal and mechanical reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Transient current sink for negative ESD events | Connected to signal line; conducts during negative transients to ground reference. |
| Cathode (Pin 2) | Transient current sink for positive ESD events | Connected to same signal line; conducts during positive transients to ground reference - bidirectional operation enabled by symmetric layout. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD suppression | Single-channel architecture protects both polarities of fast transients without polarity-sensitive routing. |
| Ultra-low 6pF capacitance | Preserves signal edge rate and eye diagram integrity on 480Mbps USB 2.0 and 3.4Mbps I²C buses. |
| IEC 61000-4-2 Level 4 compliance | Validated performance at ±15kV contact discharge eliminates need for system-level retesting after component change. |
| Lead-free, halogen-free "Green" construction | Meets RoHS 3 (2015/863/EU), J-STD-020 Level 1 moisture sensitivity, and automotive-grade material definitions. |
Applications
| USB 2.0 Data Lines | HDMI Hot-Plug Detection |
|---|---|
Use Scenario: Protecting D+ and D− pins of USB 2.0 ports against repeated electrostatic discharge during cable insertion/removal. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed within 2mm of connector, clamping surges before they reach host controller PHY. Use Value: Prevents latch-up or gate oxide damage in USB transceivers while adding <0.1ns propagation delay due to 6pF loading. | Use Scenario: Safeguarding HDMI HPD (Hot-Plug Detect) line against ESD during mating/unmating of display cables. IC Role / Device Role / Timing Role: Low-capacitance shunt protector on 5V-tolerant HPD signal path, ensuring robust detection without false disconnects. Use Value: Maintains DC logic threshold margin (≥3.5V valid high) under surge conditions, enabling reliable plug-and-play functionality. |
| Smartphone Audio Jacks | Digital Camera SDIO Interfaces |
Use Scenario: Shielding 3.5mm TRRS audio jack contacts (MIC, GND, L/R) from user-hand ESD in handheld devices. IC Role / Device Role / Timing Role: Single-channel TVS applied per signal line, leveraging 0.3mm height to fit beneath thin bezels and metal shields. Use Value: Eliminates pop/click artifacts and microphone dropout caused by ESD-induced bias shift in audio codecs. | Use Scenario: Protecting four-bit SDIO data lines (D0–D3) and CMD line in compact camera modules with microSD slots. IC Role / Device Role / Timing Role: One TVS per line placed adjacent to card connector, minimizing trace inductance to achieve sub-9V clamping at 3A. Use Value: Prevents SD card initialization failure and CRC errors induced by ESD coupling into high-impedance SDIO receivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A-Q | DO-214AC package (4.5mm × 3.2mm); 100pF capacitance; 12.5V clamping at 3A | Not suitable for high-speed interfaces; used in power rail or low-frequency analog protection | Select only when board space allows larger footprint and signal bandwidth <10MHz. |
| TPD2E001DRYR | 2-channel, 12pF per channel, 5-pin UQFN; 10V clamping at 1A | Higher capacitance limits use to ≤48Mbps interfaces; integrated dual-channel reduces layout count | Prefer for multi-line protection where shared ground and compactness outweigh single-line optimization. |
Compared with SMAJ5.0A-Q and TPD2E001DRYR, D5V0Q1B2LP3-7 uniquely balances ultra-miniaturization, sub-10V clamping at full 3A, and 6pF loading-making it optimal for next-gen portable interfaces where size, speed, and surge margin are simultaneously constrained.

FAQ
What is the maximum clamping voltage of D5V0Q1B2LP3-7 at 3A peak pulse current?
The maximum clamping voltage is 11.0V under 8/20µs waveform conditions, measured per Figure 1 in DS37519 Rev. 3-2. This value ensures protected ICs with 5.5V absolute maximum ratings remain within safe operating limits during worst-case ESD events.
Can D5V0Q1B2LP3-7 be used on a 3.3V I²C bus?
Yes - its 5.5V reverse standoff voltage exceeds the 3.3V bus voltage with sufficient margin, and its 6pF capacitance introduces negligible rise-time degradation on standard-mode (100kHz) or fast-mode (400kHz) I²C lines. Leakage remains below 100nA at 3.3V, preserving bus pull-up efficiency.
Is the X3-DFN0603-2 package compatible with standard reflow profiles?
Yes - the device is rated for Moisture Sensitivity Level 1 per J-STD-020 and supports industry-standard Pb-free reflow profiles (peak temperature ≤260°C). Its matte tin finish ensures reliable solderability using SnAgCu paste and standard stencil apertures for 0.3mm pitch.
Does D5V0Q1B2LP3-7 meet automotive qualification standards?
No - this part is not AEC-Q200 qualified. While it shares material and process attributes with automotive-grade variants (e.g., halogen-free molding compound), it lacks PPAP documentation, extended temperature validation, and IATF 16949-controlled lot traceability required for automotive applications.
