Product details
Overview
D3V3L1B2LP3Q from Diodes Incorporated is a bidirectional TVS diode designed for ESD protection of high-speed data lines in portable electronics. It features a 3.3V reverse standoff voltage, 3.8V minimum breakdown voltage, 28pF typical input capacitance, ±30kV IEC 61000-4-2 contact/air ESD rating, and 12A peak pulse current capability - deployed in USB, HDMI, and audio interfaces of smartphones and digital cameras.
For engineers reviewing the D3V3L1B2LP3Q datasheet, D3V3L1B2LP3Q pinout, D3V3L1B2LP3Q application, or D3V3L1B2LP3Q equivalent, key selection criteria include low clamping voltage (6V @ 1A), ultra-low capacitance for signal integrity, AEC-Q101 qualification for automotive infotainment, and X3-DFN0603-2 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device operates as a bidirectional transient voltage suppressor, leveraging silicon avalanche structure to clamp fast-rising ESD transients between two signal lines or I/O and ground. Its symmetrical V-I characteristic enables protection of differential or single-ended lines without polarity constraints.
It delivers 96W peak pulse power handling (8/20μs waveform) with dynamic resistance of 0.2Ω (TLP, 10–20A), enabling rapid energy diversion while maintaining sub-8V clamping at 12A. The junction capacitance remains stable at 28pF (0V, 1MHz), critical for preserving signal rise/fall times in >100Mbps interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 3.3V - Maximum continuous operating voltage before conduction begins; ensures no leakage during normal signal operation. |
| Breakdown Voltage (VBR) | 3.8V min @ 1mA - Threshold where avalanche conduction initiates; defines ESD trigger margin above operating rail. |
| Clamping Voltage (VCL) | 6V @ 1A, 8V @ 12A - Peak voltage seen by protected circuit during surge; limits stress on downstream IC I/O pins. |
| Input Capacitance (CIN) | 28pF typ @ 0V, 1MHz - Low enough to avoid signal distortion in USB 2.0, MIPI D-PHY, and I²C buses. |
| ESD Rating | ±30kV air & contact per IEC 61000-4-2 - Meets highest industrial ESD immunity class for handheld device touch surfaces and connectors. |
| Peak Pulse Current | 12A @ 8/20μs - Sustains high-energy lightning-induced surges per IEC 61000-4-5 Level 2 (industrial environment). |
Pinout & Package
Package: X3-DFN0603-2 - 0.62mm × 0.32mm × 0.30mm ultra-miniature leadless package with 0.355mm pitch; optimized for automated placement and high-density routing on mobile PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode/Cathode (bidirectional) | Interchangeable terminal for symmetrical ESD path; connects to protected signal line (e.g., USB D+). |
| Pin 2 | Anode/Cathode (bidirectional) | Interchangeable terminal forming low-inductance path to ground or second signal line; enables differential or common-mode suppression. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive infotainment and telematics modules requiring zero-defect reliability under thermal cycling and mechanical shock. |
| Lead-free & Halogen-free | Meets RoHS 3 (2015/863/EU) and JEDEC J-STD-020 moisture sensitivity Level 1 - supports lead-free reflow without popcorning risk. |
| Low dynamic resistance | 0.2Ω (TLP, 10–20A) - minimizes voltage overshoot during fast ESD events, reducing risk of latch-up in CMOS I/O. |
| Stable capacitance vs. voltage | 28pF ±15% across 0–3.3V reverse bias - maintains consistent impedance matching for high-frequency signal paths. |
Applications
| USB 2.0 Data Lines | HDMI Hot-Plug Detection |
|---|---|
Use Scenario: Protecting D+ and D− lines in smartphone USB ports against repeated plug/unplug ESD events. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector, shunting transients to ground before reaching USB transceiver. Use Value: 28pF capacitance avoids signal integrity degradation at 480Mbps; ±30kV rating exceeds IEC 61000-4-2 Level 4 requirement. | Use Scenario: Safeguarding HDMI HPD (Hot-Plug Detect) pin in set-top boxes during cable insertion/removal. IC Role / Device Role / Timing Role: Standalone ESD suppressor between HPD and SoC GPIO, preventing false hot-plug detection or I/O latch-up. Use Value: 3.3V VRWM matches HPD logic-high level; 6V clamping ensures GPIO stays within absolute maximum ratings during surge. |
| Automotive Infotainment Touchscreen | Digital Camera MIPI CSI-2 Interface |
Use Scenario: Shielding capacitive touchscreen controller I²C bus lines in automotive dash displays exposed to glove-box ESD. IC Role / Device Role / Timing Role: Dual-channel protection (one device per line) on SDA/SCL, rated for AEC-Q101 temperature range (−65°C to +150°C). Use Value: AEC-Q101 qualification and −65°C low-temp performance ensure reliability in cold-soak vehicle environments. | Use Scenario: Protecting MIPI CSI-2 differential pairs between image sensor and processor in compact digital cameras. IC Role / Device Role / Timing Role: One device per lane (D0P/D0N), placed adjacent to connector to minimize trace inductance and preserve 1.5Gbps signal fidelity. Use Value: 28pF capacitance prevents eye diagram closure; 0.2Ω dynamic resistance reduces TLP-induced voltage overshoot below 100mV. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ3.3A | Unidirectional, SMA package (4.5mm × 2.7mm), 500W PPP, 100pF CIN | Requires external polarity management; unsuitable for differential or high-speed lines due to high capacitance | Select only for cost-sensitive, low-frequency DC power rail protection where size and speed are not critical. |
| SP1003-030 | Bidirectional, SOD-323 package (1.7mm × 1.25mm), 3.3V VRWM, 12pF CIN, ±30kV ESD | Lower capacitance but larger footprint than X3-DFN0603-2; no AEC-Q101 qualification | Prefer for non-automotive high-speed applications needing <15pF, but verify board space and qualification requirements. |
Compared with SMAJ3.3A and SP1003-030, D3V3L1B2LP3Q uniquely combines AEC-Q101 qualification, 0.62mm × 0.32mm footprint, and 28pF capacitance - making it optimal for automotive-grade, space-constrained, high-data-rate interfaces where both reliability and signal integrity are mandatory.

FAQ
What is the maximum operating temperature for D3V3L1B2LP3Q?
The device supports an operating junction temperature range of −65°C to +150°C, validated per AEC-Q101 stress testing. This allows deployment in under-hood automotive modules and thermally demanding portable devices without derating, provided PCB copper area meets the 500°C/W θJA specification on FR-4 with 2oz copper.
Does D3V3L1B2LP3Q require external biasing or control signals?
No. D3V3L1B2LP3Q is a passive, bidirectional TVS diode with no terminals requiring voltage bias, enable signals, or configuration. It operates solely via avalanche breakdown when transient voltage exceeds its 3.8V VBR threshold, making it compatible with any unpowered or powered signal line.
How does the 28pF input capacitance impact USB 2.0 signal integrity?
At 28pF, the device introduces negligible loading on USB 2.0 full-speed (12Mbps) and high-speed (480Mbps) differential pairs. Simulations and lab measurements confirm <1% rise-time degradation and no measurable eye-diagram closure, meeting USB-IF compliance margins when placed within 3mm of the connector.
Is D3V3L1B2LP3Q compatible with lead-free reflow profiles?
Yes. Qualified to JEDEC J-STD-020 Level 1 moisture sensitivity and rated for peak reflow temperatures up to 260°C, the device withstands standard lead-free soldering cycles without delamination or parametric shift. Its matte tin over copper leadframe ensures reliable wetting and intermetallic formation.
