Product details
Overview
D3V3HN1B2LP from Diodes Incorporated is a single-channel bidirectional TVS diode designed for ESD and surge protection of high-speed data lines in portable electronics. It features a 3.3V reverse working voltage (VRWM), 3.8V minimum breakdown voltage (VBR), 70A peak pulse current (IPP), 140pF typical junction capacitance (CT), and ±30kV IEC 61000-4-2 ESD rating - deployed in USB, HDMI, and audio interfaces of smartphones and digital cameras.
For engineers reviewing the D3V3HN1B2LP datasheet, D3V3HN1B2LP pinout, D3V3HN1B2LP application, or D3V3HN1B2LP equivalent, key selection criteria include clamping voltage at 70A (8.5V), ultra-low profile U-DFN1006-2 package (0.5mm height), thermal resistance (500°C/W), and IEC 61000-4-5 surge compliance - critical for space-constrained, battery-powered designs requiring robust transient immunity.
Technical Context
This bidirectional TVS operates symmetrically between Pin 1 and Pin 2, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its low 140pF capacitance minimizes signal distortion on high-frequency lines up to ~100MHz, while the 5.0V clamping voltage at 1A supports fast transient suppression before downstream ICs experience overstress.
The device uses silicon avalanche technology with controlled snapback characteristics, delivering stable clamping across temperature (–55°C to +150°C) and maintaining <0.5µA leakage at 3.3V. Its U-DFN1006-2 (Type B) package integrates NiPdAu-plated terminals for reliable solderability and meets J-STD-020 Level 1 moisture sensitivity requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 3.3V - Maximum continuous reverse voltage before leakage exceeds 0.5µA; sets upper limit for signal swing in protected interface. |
| VBR (Min) | 3.8V - Minimum voltage at which avalanche conduction begins (1mA test); ensures reliable triggering above normal operating voltage. |
| VCL @ 70A | 8.5V - Clamped voltage during worst-case 8/20µs surge; defines maximum stress imposed on downstream ICs. |
| CT (Typ) | 140pF - Junction capacitance at 0V bias and 1MHz; determines insertion loss and bandwidth impact on high-speed signals. |
| IPP (Max) | 70A - Peak pulse current survivability per IEC 61000-4-5; validates robustness against lightning-induced surges. |
| ESD Rating | ±30kV contact/air - Compliance with IEC 61000-4-2 Level 4; qualifies for direct user-interface ESD hardening. |
| RθJA | 500°C/W - Thermal resistance from junction to ambient on standard FR-4 pad layout; informs derating above 25°C ambient. |
Pinout & Package
Package: U-DFN1006-2 (Type B), 0.50mm typical height, 1.00mm × 0.60mm footprint, lead-free and halogen-free "Green" molding compound (UL 94V-0).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode/Cathode (bidirectional) | Shared terminal for symmetrical transient conduction; no polarity assignment - connects to protected line (e.g., USB D+). |
| Pin 2 | Anode/Cathode (bidirectional) | Paired terminal forming low-inductance path with Pin 1; completes ESD/surge shunt path to GND or adjacent line. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC-coupled or differential signals (e.g., USB 2.0, HDMI TMDS) without polarity-sensitive placement. |
| Ultra-low profile (0.5mm) | Reduces Z-height constraint in slim mobile enclosures - fits beneath camera modules and display flex cables. |
| 140pF capacitance | Preserves signal integrity on 480Mbps USB 2.0 channels with <0.5dB insertion loss at 240MHz. |
| ±30kV ESD immunity | Meets highest IEC 61000-4-2 level without external RC filtering - eliminates need for secondary protection stages. |
| U-DFN1006-2 footprint | Minimizes PCB area (1.3mm × 0.55mm max) - allows placement directly at connector entry point for shortest transient path. |
Applications
| Smartphone Front-Facing Camera Interface | USB 2.0 OTG Port Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ3.3A | Unidirectional, SMA package (4.5mm × 2.7mm), higher CT (250pF), lower IPP (41.7A) | Requires polarity-aware layout; unsuitable for differential lines or space-constrained PCBs | Select only when board area >20× larger and unidirectional protection suffices |
| SP1003-030 | Bi-directional, SOD-323 package (1.7mm × 1.3mm), CT = 120pF, IPP = 30A, VBR = 3.6V | Lower surge rating limits use to consumer-grade handhelds, not industrial surge environments | Choose where 30A IPP is sufficient and 120pF capacitance provides margin for >500Mbps links |
Compared with SMAJ3.3A and SP1003-030, D3V3HN1B2LP uniquely balances ultra-small size, bidirectional symmetry, 70A surge capability, and 140pF capacitance - making it optimal for next-gen portable interfaces where PCB real estate and multi-kV ESD immunity are simultaneously constrained.

FAQ
What is the maximum clamping voltage under full-rated surge current?
The D3V3HN1B2LP clamps to 8.5V when subjected to a 70A, 8/20µs surge waveform - measured pin-to-pin with specified test conditions per IEC 61000-4-5. This value ensures protected ICs with 3.3V I/O rails remain below absolute maximum ratings during worst-case transients.
Can this TVS be used on high-speed differential pairs like HDMI or USB 3.0?
No - D3V3HN1B2LP is rated for 140pF capacitance and validated for USB 2.0 (480Mbps) and MIPI CSI-2 (1.5Gbps). Its capacitance exceeds recommended limits for USB 3.0 SuperSpeed (5Gbps) or HDMI 2.0 (6Gbps), where <1.5pF is typically required to avoid signal degradation.
Is the U-DFN1006-2 package compatible with standard reflow profiles?
Yes - the device is qualified to J-STD-020 Level 1 moisture sensitivity and supports standard Pb-free reflow profiles (peak 260°C, 30 seconds max). Its NiPdAu-plated copper leadframe ensures wetting reliability on OSP- and ENIG-finished PCBs without voiding or dewetting.
Does this part meet automotive qualification standards?
No - D3V3HN1B2LP is not AEC-Q200 qualified. While it operates from –55°C to +150°C and uses green materials, Diodes explicitly states automotive-grade variants require separate PPAP-capable part numbers and IATF 16949 manufacturing - this variant is intended for commercial portable electronics.
