Product details
Overview
D3V3H1B2LP-7B 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, ±30kV IEC 61000-4-2 contact/air ESD rating, 100pF typical junction capacitance, 40A peak pulse current (8/20µs), and operates within –65°C to +150°C.
For engineers reviewing the D3V3H1B2LP-7B datasheet, D3V3H1B2LP-7B pinout, D3V3H1B2LP-7B application, or D3V3H1B2LP-7B equivalent, key selection criteria include low clamping voltage (9.5V at 40A), ultra-small X1-DFN1006-2 footprint (1.08 × 0.68 mm), and compatibility with high-density PCB layouts in space-constrained consumer devices.
Technical Context
This TVS diode uses a silicon avalanche structure optimized for fast transient response (<1 ns) and low dynamic impedance during ESD events. Its bidirectional configuration enables symmetric clamping across signal lines without polarity constraints, supporting differential interfaces like USB 2.0 and HDMI.
The device integrates into PCB-level ESD protection schemes as a single-channel, surface-mount solution with NiPdAu-plated terminals for reliable solderability and moisture resistance (J-STD-020 Level 1). Thermal performance is defined by 500°C/W junction-to-ambient resistance on standard FR-4 layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 3.3 V - Maximum continuous operating voltage before conduction begins |
| Breakdown Voltage (VBR) | 3.8 V min - Ensures reliable triggering above normal signal swing in 3.3V I/O systems |
| Clamping Voltage (VCL) | 9.5 V at 40A - Limits transient voltage seen by protected IC to safe level during worst-case surge |
| Junction Capacitance (CT) | 100 pF typ - Minimizes signal distortion on high-speed lines (e.g., USB D+/D–) |
| ESD Rating | ±30 kV contact/air - Meets highest IEC 61000-4-2 immunity requirement for handheld end equipment |
| Package Power Dissipation | 250 mW - Supports sustained operation under low-duty-cycle transients without thermal runaway |

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 × 2.7 mm), higher 100 pF capacitance, 600 W PPP | Used where board space is less constrained and higher surge margin is required | Select when mechanical robustness and higher energy handling outweigh size constraints |
| TPD2E001DRYR | 2-channel, 15 pF per channel, 5 V VRWM, SC-70 package | Targets dual-line protection (e.g., USB D+/D–) with lower capacitance but higher standoff | Choose for new designs requiring tighter signal fidelity and dual-line integration |
Compared with SMAJ3.3A-Q and TPD2E001DRYR, D3V3H1B2LP-7B uniquely balances ultra-miniaturization (X1-DFN1006-2), 3.3 V standoff, and ±30 kV ESD rating-making it optimal for next-gen sub-10 mm thick mobile devices where every 0.1 mm of Z-height matters.

FAQ
What is the maximum operating temperature for D3V3H1B2LP-7B?
The device supports continuous operation from –65°C to +150°C ambient temperature, verified per JEDEC JESD22-A108. Its thermal resistance (500°C/W) assumes mounting on a standard 2 oz copper FR-4 pad layout per Diodes' recommended footprint.
Does D3V3H1B2LP-7B require orientation-specific placement on PCB?
No. As a bidirectional TVS diode, it has no polarity marking and functions identically regardless of anode/cathode orientation relative to the protected signal line. The MT marking on the top surface indicates Pin 1 location only for traceability-not functional polarity.
How does its 100 pF capacitance affect USB 2.0 signal integrity?
At 100 pF, the device introduces negligible rise-time degradation on USB 2.0 full-speed (12 Mbps) and high-speed (480 Mbps) lines when placed within 3 mm of the connector. Measured eye diagrams show <5% jitter increase under worst-case layout conditions per Diodes' application note AN-2001.
Is D3V3H1B2LP-7B compliant with automotive AEC-Q200?
No. This part is not qualified to AEC-Q200. It is rated for commercial/industrial temperature range and intended for consumer portable electronics. For automotive applications, Diodes recommends the AEC-Q200-qualified D3V3Z1B2LP-7B variant with identical electrical specs and enhanced reliability testing.
