Product details
Overview
D2V5L1BS2LP4-7B from Diodes Incorporated is a single-channel bidirectional transient voltage suppressor (TVS) diode designed for ESD and surge protection of high-speed data lines in portable electronics. It features a 2.6V minimum breakdown voltage, ±30kV IEC 61000-4-2 contact/air ESD rating, 15A peak pulse current (8/20µs), 30pF typical junction capacitance, and operates within –55°C to +150°C. It is deployed on USB, HDMI, and audio interface lines in smartphones and digital cameras.
For engineers reviewing the D2V5L1BS2LP4-7B datasheet, D2V5L1BS2LP4-7B pinout, D2V5L1BS2LP4-7B application, or D2V5L1BS2LP4-7B equivalent, key selection criteria include clamping voltage at 1–15A, low capacitance for signal integrity, ultra-small X2-DFN1006-2 footprint, RoHS/Green compliance, and IEC 61000-4-5 surge capability.
Technical Context
This TVS uses a planar silicon avalanche structure optimized for bidirectional clamping across both polarities without polarity marking. Its low 30pF capacitance and sub-6V clamping at 15A enable protection of 500Mbps+ interfaces while minimizing signal distortion.
The device employs a monolithic dual-junction design with symmetrical VBR (2.6V min) and matched forward/reverse clamping behavior. Thermal resistance (RθJA = 500°C/W) and 250mW steady-state power dissipation are specified for FR-4 PCB mounting per Diodes' recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (Min) | 2.6V - Ensures reliable conduction onset before damage to 2.5V logic or USB 2.0 I/O rails |
| IPP (Max) | 15A (8/20µs) - Withstands lightning-induced surges per IEC 61000-4-5 Level 3 |
| CT (Typ) | 30pF @ 0V, 1MHz - Low enough to avoid signal degradation on 480Mbps USB 2.0 lines |
| VCL @ 15A | 6.0V max - Limits voltage seen by protected IC to safe level during full surge event |
| ESD Rating | ±30kV air / ±30kV contact - Meets highest IEC 61000-4-2 Level 4 immunity requirement |
| Package | X2-DFN1006-2 - 1.1mm × 0.7mm footprint with 0.37mm profile for space-constrained PCBs |
Pinout & Package
Package: X2-DFN1006-2 - ultra-compact, leadless, two-terminal surface-mount package with NiPdAu-plated copper leadframe and UL 94V-0 molding compound. Moisture sensitivity level 1 (J-STD-020).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode/Cathode (bidirectional) | Non-polarized terminal; functions as cathode under positive transients, anode under negative transients |
| Pin 2 | Anode/Cathode (bidirectional) | Complementary terminal; completes symmetrical clamping path across protected line |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or differential signal lines (e.g., USB D+/D−) without polarity concerns |
| Low 30pF capacitance | Maintains signal rise/fall time integrity on high-speed interfaces up to 480Mbps |
| ±30kV ESD robustness | Eliminates need for secondary ESD protection stages in handheld device front-end designs |
| 0.37mm profile | Allows placement adjacent to connectors or under shields in slim-profile mobile PCBs |
Applications
| USB 2.0 Interface Protection | HDMI Data Lane Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 ports in smartphones against connector hot-plug ESD and cable discharge events. IC Role / Device Role / Timing Role: Bidirectional TVS placed directly at USB connector, clamping transients before they reach the USB transceiver IC. Use Value: 30pF capacitance avoids signal integrity loss at 480Mbps; ±30kV ESD rating exceeds IEC 61000-4-2 Level 4 requirements. | Use Scenario: Shielding TMDS data channels in portable HDMI adapters from ESD during cable insertion and handling. IC Role / Device Role / Timing Role: Low-capacitance TVS mounted at HDMI receptacle to suppress fast-rising ESD pulses without degrading 165MHz pixel clock timing. Use Value: Sub-6V clamping at 15A ensures downstream HDMI receiver remains within absolute maximum ratings during surge events. |
| Smartphone Audio Jack Protection | Industrial Sensor Interface Protection |
Use Scenario: Safeguarding 3.5mm audio jack MIC and GND lines in mobile handsets from user-hand ESD during plug insertion/removal. IC Role / Device Role / Timing Role: Two-device array (one per line) providing symmetric clamping on analog audio paths with minimal DC loading. Use Value: 1.0µA max reverse leakage at 2.5V preserves battery life; 2.6V VBR avoids false triggering on 2.8V bias rails. | Use Scenario: Protecting RS-485 or CAN FD transceiver inputs in industrial handheld testers exposed to field ESD and induced surges. IC Role / Device Role / Timing Role: Front-end TVS on differential bus lines, absorbing energy before it reaches isolated transceiver input stage. Use Value: 90W peak pulse power and 15A IPP support IEC 61000-4-5 Level 3 surge immunity in ungrounded portable equipment. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ2.5A | DO-214AC package (4.5mm × 2.7mm); 35pF capacitance; 24.4V VBR; 23.1A IPP | Designed for higher-voltage industrial power rails, not high-speed data lines | Select only when board space allows larger footprint and signal bandwidth <100MHz |
| SP1003-02HTG | SOD-882 package (1.3mm × 0.85mm); 15pF capacitance; 3.3V VBR; 12A IPP | Lower capacitance but higher VBR limits use on 2.5V/3.3V I/O with tight margin | Prefer for >1Gbps interfaces where <20pF is mandatory, accepting higher clamping voltage |
Compared with SMAJ2.5A and SP1003-02HTG, D2V5L1BS2LP4-7B uniquely balances ultra-small size (1.1mm × 0.7mm), 30pF capacitance, and 2.6V VBR-making it optimal for compact 2.5V–3.3V high-speed data protection where board area and signal fidelity are jointly constrained.

FAQ
What is the maximum clamping voltage at 15A for D2V5L1BS2LP4-7B?
The maximum clamping voltage is 6.0V at 15A (8/20µs waveform), measured per IEC 61000-4-5 test conditions. This value ensures protected ICs remain within their absolute maximum voltage ratings during worst-case surge events, and is verified in Diodes' DS44248 datasheet Figure 6.
Can D2V5L1BS2LP4-7B be used on 5V logic lines?
No-it is not recommended for 5V systems. Its 2.6V minimum breakdown voltage and 6.0V clamping at 15A provide insufficient margin above 5V rail voltage, risking premature conduction and system malfunction. It is optimized for 2.5V–3.3V interfaces like USB 2.0 and audio codecs.
Is the X2-DFN1006-2 package compatible with standard reflow profiles?
Yes-the device is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 and supports standard Pb-free reflow profiles (peak temperature ≤260°C). Its NiPdAu-plated terminals ensure reliable solderability per MIL-STD-202, Method 208.
Does D2V5L1BS2LP4-7B meet automotive qualification standards?
No-this part is not AEC-Q200 qualified. While Diodes offers automotive-grade variants in the same X2-DFN family, D2V5L1BS2LP4-7B is intended for commercial portable electronics. For automotive applications, consult Diodes' AEC-Q200-certified TVS portfolio and contact their automotive support team.
