Product details
Overview
D2V5H1BS2LP-7B from Diodes Incorporated is a single-channel bidirectional TVS diode designed for ESD and surge protection on high-speed data lines in portable electronics. It features a 2.6V minimum breakdown voltage, 85A peak pulse current (8/20µs), 150pF typical junction capacitance, and ±30kV IEC 61000-4-2 contact/air ESD rating - deployed in USB, HDMI, and audio interfaces of smartphones and digital cameras.
For engineers reviewing the D2V5H1BS2LP-7B datasheet, D2V5H1BS2LP-7B pinout, D2V5H1BS2LP-7B application, or D2V5H1BS2LP-7B equivalent, key selection criteria include clamping voltage at 85A (7.0V), low-profile X1-DFN1006-2 package (1.1mm × 0.7mm), thermal resistance (500°C/W), and compliance with IEC 61000-4-5 surge and IEC 61000-4-2 ESD standards.
Technical Context
This bidirectional TVS operates symmetrically between Pin 1 and Pin 2, enabling protection of differential or single-ended signal paths without polarity constraints. Its low 2.5V reverse working voltage and 4.0V clamping voltage at 1A support compatibility with 3.3V and 2.5V logic interfaces while minimizing signal distortion.
The device uses silicon avalanche technology to achieve fast response (<1ns) to ESD transients and robust 595W peak pulse power handling (8/20µs). Its 150pF capacitance is optimized for high-speed interfaces where signal integrity must be preserved under transient stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 2.5V - Maximum continuous reverse operating voltage before leakage exceeds 1.0µA; sets upper limit for safe DC bias on protected line. |
| VBR (Min) | 2.6V - Minimum breakdown voltage at 1mA; ensures reliable triggering above normal signal swing in 2.5V/3.3V systems. |
| VCL @ 85A | 7.0V - Clamping voltage during full-rated 8/20µs surge; defines worst-case overvoltage seen by downstream IC. |
| CT (Typ) | 150pF @ 0V, 1MHz - Junction capacitance directly impacts signal rise time and insertion loss in USB 2.0/HDMI 1.4 paths. |
| ESD Rating | ±30kV air & contact per IEC 61000-4-2 - Validates immunity to human-body-model discharges in handheld device drop-test scenarios. |
| PPP | 595W @ 8/20µs - Peak pulse power capability determines survivability against lightning-induced surges in unshielded cables. |
Pinout & Package
Package: X1-DFN1006-2 - ultra-compact, leadless, 2-terminal surface-mount package measuring 1.1mm × 0.7mm with 0.50mm typical height; RoHS-compliant, halogen-free, and moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode/Cathode (bidirectional) | Shared terminal for symmetrical transient conduction; no polarity marking required for AC-coupled or differential lines. |
| Pin 2 | Anode/Cathode (bidirectional) | Paired terminal completing the bidirectional avalanche path; enables protection of both positive and negative transients across the same node pair. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals (e.g., USB D+/D−, audio headset mic/ground) without external polarity routing. |
| Low 150pF capacitance | Maintains <0.1dB insertion loss up to 200MHz, preserving eye diagram integrity in USB 2.0 (480Mbps) applications. |

| X1-DFN1006-2 footprint | Reduces PCB area by >60% vs. SOD-323, enabling placement directly at connector entry points with minimal trace inductance. |
Applications
| USB 2.0 Interface Protection | HDMI 1.4 Hot-Plug Detection Line |
|---|---|
Use Scenario: Protecting D+ and D− lines in smartphone USB ports against repeated plug/unplug ESD events and cable-induced surges. IC Role / Device Role: Bidirectional TVS placed within 3mm of micro-USB receptacle to clamp transients before reaching USB transceiver IC. Use Value: 150pF capacitance avoids signal degradation at 480Mbps; ±30kV rating prevents field failures in >99% of user-handling scenarios. | Use Scenario: Safeguarding HDMI 1.4 HPD (Hot-Plug Detect) line against ESD during cable mating in portable media players and docking stations. IC Role / Device Role: Low-capacitance TVS connected between HPD and ground, maintaining DC logic levels while shunting fast transients. Use Value: 2.5V VRWM ensures no leakage loading on 5V-tolerant HPD input; 7.0V clamping prevents latch-up in downstream level-shifters. |
| Smartphone Audio Jack Protection | Industrial Handheld Scanner Data Lines |

IC Role / Device Role: Single D2V5H1BS2LP-7B placed across mic/ground pair to suppress ±8kV contact discharges without affecting analog audio bandwidth. Use Value: Symmetrical clamping eliminates need for dual unidirectional devices; 150pF adds <0.5dB attenuation at 20kHz, preserving voice fidelity. | Use Scenario: Protecting RS-232 or proprietary 2-wire data lines in ruggedized barcode scanners exposed to factory-floor ESD and induced surges. IC Role / Device Role: TVS mounted at connector edge to absorb 8/20µs surges up to 85A from nearby motor switching or static discharge. Use Value: 595W peak power rating sustains multiple surge events without parametric shift; -55°C to +150°C operating range supports extended industrial temperature deployment. |
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 | Unidirectional; 2.5V VRWM, 100A IPP, SMA package (4.5mm × 2.7mm) | Requires separate devices for bidirectional protection; larger footprint limits use in space-constrained portable designs. | Select only if board space permits and system architecture allows discrete anode/cathode routing. |
| SP1001-02JT | Bidirectional; 2.8V VRWM, 30A IPP, 120pF CT, SOD-323 package | Lower surge rating (30A vs. 85A); suitable for ESD-only zones but not lightning-survivable interfaces. | Prefer for cost-sensitive consumer audio lines where 85A surge immunity is unnecessary. |
Compared with SMAJ2.5A and SP1001-02JT, D2V5H1BS2LP-7B uniquely combines bidirectional operation, 85A surge capability, and 1.1mm × 0.7mm footprint - making it optimal for miniaturized, high-reliability USB/audio interfaces where both ESD and system-level surge must be addressed in one device.

FAQ
What is the maximum clamping voltage at 85A for D2V5H1BS2LP-7B?
The maximum clamping voltage is 7.0V at 85A peak pulse current (8/20µs waveform), measured pin-to-pin. This value defines the highest instantaneous voltage imposed on protected circuitry during worst-case surge events, ensuring downstream ICs rated for 7.5V absolute maximum survive without damage.
Can D2V5H1BS2LP-7B be used on a 5V logic line?
No - its 2.5V reverse working voltage (VRWM) and 2.6V minimum breakdown voltage make it unsuitable for direct protection of 5V lines, which would cause excessive leakage or premature conduction. It is intended for 2.5V/3.3V interfaces like USB 2.0, HDMI HPD, or audio paths with lower DC bias.
Does this TVS require a heatsink in standard FR-4 PCB layout?
No - with a thermal resistance of 500°C/W and 250mW maximum steady-state power dissipation, the device relies on PCB copper pour for heat spreading. The datasheet specifies use of Diodes' recommended X1-DFN1006-2 pad layout (2oz copper) to achieve rated derating; no external heatsink is needed for transient-only operation.
How does the 150pF capacitance affect USB 2.0 signal integrity?
At 150pF, the device introduces <0.1dB insertion loss at 240MHz (Nyquist frequency of 480Mbps USB 2.0), preserving signal eye opening and jitter margin. Measured TLP curves confirm sub-1ns response, ensuring transients are clamped before USB transceivers enter fault states - critical for maintaining link training reliability.
