Product details
Overview
D3V3S1B2LP-7B from Diodes Incorporated is a bidirectional transient voltage suppression (TVS) diode designed for ESD protection of high-speed data lines in portable electronics. It features a 3.3 V reverse standoff voltage, ±30 kV IEC 61000-4-2 contact/air ESD rating, 118 pF typical channel capacitance, 50 A peak pulse current (8/20 µs), and operates within –55 °C to +150 °C.
For engineers reviewing the D3V3S1B2LP-7B datasheet, D3V3S1B2LP-7B pinout, D3V3S1B2LP-7B application, or D3V3S1B2LP-7B equivalent, key selection criteria include low clamping voltage (9.5 V at 40 A), ultra-small X1-DFN1006-2 footprint (1.08 mm × 0.68 mm), and compatibility with high-density PCB layouts in space-constrained mobile interfaces.
Technical Context
This TVS diode employs a silicon avalanche structure optimized for fast response (<1 ns) to electrostatic discharge events. Its bidirectional configuration enables symmetric clamping across signal lines without polarity constraints, supporting differential or single-ended I/O protection in USB, HDMI, and audio paths.
The device uses a low-inductance DFN package with NiPdAu-plated terminals and meets J-STD-020 moisture sensitivity Level 1. Thermal resistance is 500 °C/W (junction-to-ambient on FR-4), enabling reliable operation up to 150 °C junction temperature under derated power conditions.

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-Q | DO-214AC package (4.5 mm × 3.2 mm), higher 125 pF capacitance, 600 W PPP | Used where board space is less constrained and higher surge energy handling is needed | Select when >50 A IPP or >410 W peak power is required; not suitable for sub-1 mm² layouts |
| SP1003-030 | SOD-323 package (1.7 mm × 1.25 mm), 15 pF capacitance, lower 30 A IPP | Better for RF/analog lines requiring <20 pF but insufficient for 40 A clamping | Choose for ultra-low-capacitance analog sensor lines; avoid where ±30 kV ESD or 40 A clamping is mandatory |
Compared with SMAJ3.3A-Q and SP1003-030, D3V3S1B2LP-7B uniquely balances ultra-compact size, 118 pF capacitance, and full ±30 kV/50 A capability-making it optimal for modern high-density portable USB/audio/HDMI interfaces where space and ESD robustness are co-constrained.

FAQ
What is the maximum clamping voltage of D3V3S1B2LP-7B at 40 A?
The clamping voltage is 9.5 V at 40 A peak pulse current (8/20 µs waveform), measured per IEC 61000-4-5. This value ensures downstream ICs experience limited overvoltage during high-energy transients while maintaining compatibility with 3.3 V logic rails.
Does D3V3S1B2LP-7B require orientation during PCB placement?
No. As a bidirectional TVS diode in an X1-DFN1006-2 package, D3V3S1B2LP-7B has no polarity-either terminal may connect to the protected line or ground. The "S1" marking and bar indicate Pin 1 but do not imply directional function.
Can D3V3S1B2LP-7B be used on 5 V logic lines?
No. Its 3.3 V reverse standoff voltage and 3.8 V minimum breakdown voltage make it unsuitable for 5 V systems. Using it on 5 V lines risks premature conduction and increased leakage. For 5 V interfaces, consider D5V0S1B2LP-7B (5.0 V VRWM).
Is the X1-DFN1006-2 package compatible with standard reflow profiles?
Yes. The device is rated for moisture sensitivity Level 1 (J-STD-020) and supports standard Pb-free reflow profiles (peak 260 °C). Its NiPdAu finish ensures reliable solderability per MIL-STD-202, Method 208, with no special pre-bake required.
