Product details
Overview
D2V5H1BS2LP4-7B from Diodes Incorporated is a single-channel, bi-directional transient voltage suppression (TVS) diode designed for ESD and surge protection on high-speed data lines. It features a 2.5V reverse working voltage, 2.6V minimum breakdown voltage, 150pF typical junction capacitance, ±30kV IEC 61000-4-2 ESD rating, and 85A peak pulse current capability - deployed in cellular handsets and portable electronics signal paths.
For engineers reviewing the D2V5H1BS2LP4-7B datasheet, D2V5H1BS2LP4-7B pinout, D2V5H1BS2LP4-7B application, or D2V5H1BS2LP4-7B equivalent, key selection criteria include low clamping voltage (3.3V at 1A), ultra-low profile (0.4mm max height), IEC 61000-4-5 surge compliance, and compatibility with space-constrained USB/MIPI/SDIO interfaces.
Technical Context
This TVS operates as a bi-directional clamp between two terminals, activating symmetrically during positive or negative transients exceeding its 2.6V breakdown threshold. Its low 150pF capacitance minimizes signal integrity impact on 100+ Mbps digital interfaces, while the 3.3–7.0V clamping range (at 1–85A) ensures robust overvoltage suppression without disrupting normal 2.5V logic operation.
The device uses a planar silicon junction structure housed in an X2-DFN1006-2 package with NiPdAu-plated copper leads. Thermal resistance of 500°C/W and 250mW power dissipation rating reflect its suitability for low-power, surface-mounted PCB layouts with minimal copper area - consistent with portable electronics thermal constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Working Voltage | 2.5V - Maximum continuous DC or RMS signal voltage before leakage exceeds 1µA; sets upper limit for protected line voltage. |
| Breakdown Voltage (VBR) | 2.6V min @ 1mA - Threshold where TVS begins conducting significantly; defines earliest clamping onset for fast transients. |
| Clamping Voltage (VCL) | 3.3V typ @ 1A (8/20µs) - Actual voltage seen by protected IC during surge; critical for ensuring downstream logic stays within safe margin. |
| Peak Pulse Current (IPP) | 85A max @ 8/20µs - Maximum surge current the device can shunt without failure; validates IEC 61000-4-5 Level 4 compliance. |
| Junction Capacitance (CT) | 150pF typ @ 0V, 1MHz - Low enough to avoid signal distortion on USB 2.0, MIPI D-PHY, or SDIO lines operating up to ~100MHz. |
| ESD Rating | ±30kV contact & air (IEC 61000-4-2) - Full system-level ESD immunity without external shielding; eliminates need for secondary protection stages. |
Pinout & Package
Package: X2-DFN1006-2 - ultra-compact, 1.0 × 0.6 mm, 0.4 mm max height, lead-free, halogen-free, RoHS-compliant molded plastic package with exposed thermal pad not present (2-terminal configuration).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode/Cathode (bi-directional) | Shared terminal for symmetrical clamping; connects to signal line requiring bidirectional transient suppression. |
| Pin 2 | Anode/Cathode (bi-directional) | Paired terminal completing the TVS junction; no polarity distinction - interchangeable with Pin 1 in layout. |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional clamping architecture | Enables single-device protection of AC-coupled or differential signal lines (e.g., USB D+/D−, MIPI lanes) without polarity concerns. |
| Ultra-low 150pF capacitance | Maintains signal rise/fall times and impedance matching on high-speed interfaces up to 480 Mbps, avoiding bit errors or eye closure. |
| 3.3V clamping at 1A | Keeps protected IC I/O pins below absolute maximum ratings during ESD events, preventing latch-up or oxide damage in 2.5V/3.3V systems. |
| 0.4mm max profile | Allows placement adjacent to connectors or under shields in smartphones, wearables, and TWS earbuds where Z-height is constrained. |
Applications
| USB 2.0 Data Lines | MIPI D-PHY Interfaces |
|---|---|
Use Scenario: Protecting D+ and D− lines in smartphone USB ports against repeated ESD strikes during cable insertion/removal. IC Role / Device Role: Bi-directional TVS placed directly at connector, clamping transients before they reach USB transceiver IC. Use Value: Prevents communication dropouts and port IC damage while maintaining <1% signal attenuation at 480 Mbps due to 150pF capacitance. | Use Scenario: Shielding camera sensor interface traces in compact mobile modules from board-level ESD coupling. IC Role / Device Role: Per-lane TVS on each MIPI clock and data pair, mounted within 3 mm of sensor connector per layout guidelines. Use Value: Enables >100,000 hot-plug cycles without pixel corruption or frame loss, validated per IEC 61000-4-2 ±30kV contact discharge. |
| SD Card Interface | Audio Codec Data Lines |
Use Scenario: Securing SDIO command, clock, and data lines in portable medical devices exposed to clinical ESD environments. IC Role / Device Role: Single TVS per signal line (CMD, CLK, DAT0–DAT3), placed at SD card slot edge. Use Value: Maintains 25 MHz SDHC timing margins while surviving 85A lightning-induced surges per IEC 61000-4-5. | Use Scenario: Guarding I²S or PCM data lines between baseband processor and audio codec in Bluetooth headsets. IC Role / Device Role: Low-capacitance TVS on serial data and word clock lines, minimizing jitter and SNR degradation. Use Value: Adds <0.05 dB THD+N penalty at 20 kHz while providing full ±30kV ESD immunity - critical for Class D amplifier stability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ2.5A | DO-214AC package (4.5 × 2.7 mm), 350pF capacitance, 100A IPP, 3.0V VBR | Higher capacitance limits use to DC/low-speed lines; larger footprint incompatible with mobile PCB real estate. | Select only when board space allows and signal bandwidth <10 MHz. |
| SP1003-02HTG | SOD-882 package (1.3 × 0.85 mm), 120pF CT, 30A IPP, 2.8V VBR | Lower surge rating restricts use to ESD-only scenarios; insufficient for IEC 61000-4-5 lightning surge. | Choose for cost-sensitive wearables where 85A surge immunity is not required. |
Compared with SMAJ2.5A and SP1003-02HTG, D2V5H1BS2LP4-7B uniquely balances ultra-small size, 150pF capacitance, and 85A surge capability - making it the only option qualified for high-speed, space-constrained, and system-level surge-compliant designs.

FAQ
What is the maximum operating temperature for D2V5H1BS2LP4-7B?
The device supports continuous operation from –55°C to +150°C ambient temperature. Its 500°C/W thermal resistance assumes mounting on a standard FR-4 PCB with Diodes' recommended 2oz copper pad layout; derating applies above +70°C per Figure 1 in the datasheet.
Does D2V5H1BS2LP4-7B require orientation-specific placement on PCB?
No - the device is bi-directional and symmetrical. Pins 1 and 2 are electrically identical; either terminal may connect to the signal line and the other to ground or return path. The "H6" marking identifies the device but does not indicate polarity.
Can this TVS protect HDMI or PCIe Gen3 signals?
No - its 150pF capacitance introduces excessive insertion loss above ~500 MHz. It is validated for USB 2.0 (480 Mbps), MIPI D-PHY (1.5 Gbps), and SDIO (50 MHz), but not for multi-Gbps differential protocols requiring <0.5pF per line.
Is D2V5H1BS2LP4-7B qualified for automotive AEC-Q200?
No - this variant is not AEC-Q200 qualified. Diodes offers automotive-grade equivalents (e.g., D2V5H1BS2LP4Q-7B) with PPAP documentation, IATF 16949 manufacturing, and extended temperature validation; contact Diodes sales for qualified part numbers.
