Product details
Overview
D3V3L2BS3LP-7B from Diodes Incorporated is a bidirectional dual-channel TVS diode array designed for ESD and surge protection of high-speed data lines in portable electronics. It features a 3.3 V reverse working voltage, 3.8 V minimum breakdown voltage, 8 A peak pulse current rating (8/20 µs), 18 pF typical junction capacitance, and ±30 kV IEC 61000-4-2 contact/air ESD immunity-optimized for USB, HDMI, and audio interfaces in smartphones and digital cameras.
For engineers reviewing the D3V3L2BS3LP-7B datasheet, D3V3L2BS3LP-7B pinout, D3V3L2BS3LP-7B application, or D3V3L2BS3LP-7B equivalent, key selection criteria include clamping voltage under 4.8 V at 1 A, low 18 pF capacitance for signal integrity, bidirectional symmetry for AC-coupled lines, and X1-DFN1006-3 package compatibility with space-constrained PCB layouts.
Technical Context
This device implements a monolithic dual-channel TVS structure with symmetrical bidirectional clamping between each channel (Pin 1/Pin 2) and common cathode (Pin 3), enabling simultaneous protection of two independent signal paths without polarity constraints. Its low dynamic resistance (0.16 Ω) and fast TLP response (100 ns) ensure effective transient suppression while preserving signal fidelity.
Designed for IEC 61000-4-2 and IEC 61000-4-5 compliance, it delivers ±30 kV ESD robustness and 8 A surge capability in an ultra-small footprint. The 3.3 V VRWM aligns with 3.3 V logic systems, and its 4.8 V clamping at 1 A minimizes voltage overshoot during transient events on sensitive I/O pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 3.3 V - Maximum continuous reverse operating voltage compatible with 3.3 V I/O rails without leakage-induced power loss |
| VBR (Min) | 3.8 V - Ensures reliable triggering above normal signal swing, preventing false clamping during valid operation |
| VCL @ 1A | 4.8 V - Limits transient voltage to safe levels for downstream 3.3 V logic, reducing risk of latch-up or damage |
| IPP (Max) | 8 A - Withstands 8/20 µs lightning-surge transients per IEC 61000-4-5, supporting industrial-grade robustness |
| CT (Typ) | 18 pF - Enables use on high-speed interfaces (e.g., USB 2.0, HDMI DDC) without significant signal attenuation or timing skew |
| ESD Rating | ±30 kV - Meets highest IEC 61000-4-2 contact/air discharge level, eliminating need for external ESD staging |
| PD (Max) | 250 mW - Sufficient thermal margin for intermittent surge events on FR-4 PCBs with standard pad layout |
Pinout & Package
Package: X1-DFN1006-3 - 1.0 mm × 0.6 mm × 0.5 mm ultra-thin leadless package with NiPdAu-plated copper terminals; moisture sensitivity level 1 (J-STD-020); RoHS 3 and halogen-free compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Channel 1 Anode | Bidirectional ESD path for first protected line (e.g., USB D+); symmetrically clamps to Pin 3 during positive/negative transients |
| Pin 2 | Channel 2 Anode | Bidirectional ESD path for second protected line (e.g., USB D−); electrically isolated from Pin 1 but shares common cathode |
| Pin 3 | Common Cathode | Shared low-impedance return path for both channels; must be connected to system ground with minimal inductance for optimal clamping |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional dual-channel architecture | Enables independent, polarity-agnostic protection of two signal lines (e.g., differential pairs) using single common ground connection |
| IEC 61000-4-2 ±30 kV ESD immunity | Eliminates need for secondary ESD protection stages in handheld devices, reducing BOM count and board area |
| 18 pF typical junction capacitance | Preserves signal rise/fall times on 480 Mbps USB 2.0 lines, avoiding eye diagram closure or jitter accumulation |
| X1-DFN1006-3 footprint | Reduces PCB real estate by >60% vs. SOT-523 packages, critical for thin-profile mobile PCBs with tight routing constraints |
| Lead-free, halogen-free, RoHS 3 compliant | Meets global environmental regulations and automotive supply chain requirements without compromising surge performance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel bidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J3.3A-Q | Single-channel, SMA package (4.5 mm × 2.7 mm), higher 25 pF capacitance, 12 A IPP | Requires two devices for dual-line protection; unsuitable for space-constrained layouts | Select when higher surge rating outweighs size and capacitance penalties |
| TPD2E001DRSR | Two-channel, 0.65 mm × 0.95 mm DRS package, 12 pF capacitance, 3.6 V VRWM, ±8 kV ESD | Limited to consumer-grade ESD (IEC 61000-4-2 ±8 kV), not ±30 kV; lower clamping voltage (3.8 V @ 1 A) | Select only for cost-sensitive, non-industrial applications where extreme ESD immunity is unnecessary |
Compared with SMA6J3.3A-Q and TPD2E001DRSR, D3V3L2BS3LP-7B uniquely balances ±30 kV ESD immunity, 18 pF capacitance, and X1-DFN1006-3 size-making it the only option qualified for dual-line protection in slim-profile, high-reliability portable designs requiring full IEC 61000-4-2 compliance.

FAQ
What is the maximum clamping voltage of D3V3L2BS3LP-7B at 8 A surge current?
The maximum clamping voltage is 7.3 V under an 8/20 µs waveform at 8 A peak pulse current, as specified in the Electrical Characteristics table. This value ensures downstream 3.3 V logic remains within absolute maximum ratings during worst-case surge events, provided PCB layout minimizes ground inductance to Pin 3.
Can D3V3L2BS3LP-7B protect differential high-speed signals like USB 2.0 without degrading signal integrity?
Yes-its 18 pF typical junction capacitance and symmetrical bidirectional structure preserve USB 2.0 eye diagrams up to 480 Mbps. Measured TLP curves show <0.16 Ω dynamic resistance, limiting voltage overshoot and minimizing jitter; recommended layout uses 0.25 mm trace width and controlled impedance routing to maintain signal fidelity.
Is the X1-DFN1006-3 package compatible with standard reflow profiles for lead-free assembly?
Yes-the device is rated for moisture sensitivity level 1 (J-STD-020) and supports standard IPC/JEDEC J-STD-020D reflow profiles. Its NiPdAu-plated terminals ensure reliable solder wetting at peak temperatures up to 260 °C, and the 0.5 mm height enables compatibility with automated optical inspection (AOI) systems.
Does D3V3L2BS3LP-7B meet automotive qualification standards such as AEC-Q101?
No-this part is not AEC-Q101 qualified. While Diodes offers automotive-grade variants in the same X1 family, D3V3L2BS3LP-7B is intended for commercial portable electronics. For automotive applications, consult Diodes' AEC-Q101-certified equivalents such as D3V3L2BS3LPQ-7B, which undergoes extended temperature cycling and humidity testing.
