Product details
Overview
D24V0X1B2LP-7B from Diodes Incorporated is a bidirectional TVS diode designed for ultra-low-capacitance ESD protection of high-speed signal lines. It features a 24V reverse working voltage (VRWM), 26V minimum breakdown voltage (VBR), 0.5pF typical junction capacitance (CT), ±18kV contact/±20kV air ESD rating per IEC 61000-4-2, and 2.5A peak pulse current (IPP) capability - deployed in RF front-end, USB 2.0/3.0, and NFC antenna circuits.
For engineers reviewing the D24V0X1B2LP-7B datasheet, D24V0X1B2LP-7B pinout, D24V0X1B2LP-7B application, or D24V0X1B2LP-7B equivalent, key selection criteria include low clamping voltage under transient stress, sub-1pF signal-line loading, AEC-Q qualified automotive suitability, and X1-DFN1006-2 footprint compatibility with high-density portable PCB layouts.
Technical Context
This TVS operates as a bidirectional clamp across signal pairs, triggering at ≥26V to divert ESD transients while maintaining <0.5pF capacitance at 0V bias - critical for preserving signal integrity in 480Mbps USB 2.0 and 5Gbps USB 3.0 data paths. Its low dynamic resistance (0.6Ω TLP) ensures rapid voltage suppression during 100ns ESD events.
The device uses a planar silicon junction structure in a lead-free, halogen-free X1-DFN1006-2 package with NiPdAu-plated terminals. Thermal resistance (RθJA = 500°C/W) and 250mW power dissipation are specified for FR-4 PCB mounting with Diodes' recommended 0.70mm × 0.70mm pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 24V - Maximum continuous reverse voltage before leakage exceeds 1µA; sets operating margin for 24V nominal signal rails. |
| VBR (Min) | 26V - Minimum voltage at which device enters avalanche conduction at 1mA; defines ESD trigger threshold. |
| VCL @ IPP=2.5A | 44V - Clamped voltage during 8/20µs surge; limits downstream IC stress to safe levels below 45V. |
| CT (Typ) | 0.5pF @ 0V, 1MHz - Signal-line capacitive loading; enables minimal insertion loss in >100MHz RF and high-speed digital paths. |
| ESD Rating | ±18kV contact / ±20kV air - Complies with IEC 61000-4-2 Level 4; qualifies for automotive infotainment and telematics ESD hardening. |
| Package | X1-DFN1006-2 - 1.08mm × 0.68mm footprint, 0.53mm max height; supports automated placement in space-constrained modules. |
Pinout & Package
Package: X1-DFN1006-2 - ultra-compact, bottom-terminal, lead-free plastic package with NiPdAu plating; moisture sensitivity level 1 (J-STD-020); weight ≈ 0.001g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode (Channel 1) | Connects to protected signal line; forms one side of bidirectional ESD path with Pin 2. |
| Pin 2 | Cathode (Channel 1) | Connects to ground reference; completes low-inductance ESD shunt path for both polarities. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 0.5pF typical - preserves signal rise/fall times and impedance matching in USB/NFC/RF paths. |
| Bidirectional clamping | Single-channel symmetric response - protects AC-coupled or differential signals without polarity constraints. |
| Automotive-ready construction | AEC-Q200 compliant materials and IATF 16949 manufacturing - suitable for non-safety-critical automotive electronics. |
| Green packaging | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb); RoHS 3 compliant - meets global environmental compliance mandates. |
Applications
| RF Antenna Protection | USB 2.0 Data Line Protection |
|---|---|
Use Scenario: ESD protection on cellular/Wi-Fi/GPS antenna feedlines in compact automotive telematics modules. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed between antenna switch and transceiver RF port. Use Value: 0.5pF capacitance avoids detuning of 700MHz–6GHz antenna matching networks; ±20kV air discharge withstand prevents field failures. | Use Scenario: Protecting D+ and D− lines of USB 2.0 ports in infotainment head units and docking stations. IC Role / Device Role / Timing Role: Low-capacitance TVS placed directly at connector to shunt ESD before reaching USB PHY IC. Use Value: Sub-1pF loading maintains 480Mbps eye diagram integrity; 44V clamping prevents PHY latch-up during hot-plug events. |

IC Role / Device Role / Timing Role: Transient suppressor on line-driver outputs exposed to user-accessible jacks and cables. Use Value: Low clamping voltage (≤44V) prevents op-amp output stage damage; 2.5A IPP handles cable-induced surges without degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-Q | DO-214AC package; 350W peak power; 15pF CT; unidirectional only | Higher capacitance limits use to DC/low-frequency lines; larger footprint unsuitable for mobile PCBs | Select only for cost-sensitive industrial boards where size and speed are secondary |
| SP1003-02UTG | SOD-882 package; 0.3pF CT; 17V VRWM; ±30kV ESD rating | Lower VRWM restricts use to 12V or lower signal rails; tighter tolerance increases BOM complexity | Prefer for ultra-high-speed 10Gbps+ interfaces where sub-0.4pF is mandatory |
Compared with SMAJ24A-Q and SP1003-02UTG, D24V0X1B2LP-7B uniquely balances 24V system compatibility, 0.5pF loading, and automotive-grade packaging in a 1.08mm × 0.68mm footprint - making it optimal for space-constrained, high-data-rate automotive signal protection.

FAQ
What is the maximum clamping voltage of D24V0X1B2LP-7B under full-rated surge current?
The device clamps to 44V when subjected to its maximum rated 2.5A 8/20µs peak pulse current. This value is measured per JEDEC-standard test conditions and ensures downstream components remain within safe operating voltage limits during worst-case ESD events.
Can D24V0X1B2LP-7B be used in automotive AEC-Q200-compliant designs?
Yes - while D24V0X1B2LP-7B itself is not AEC-Q200 certified, it is manufactured in IATF 16949-certified facilities using AEC-Q200-aligned materials and processes. Diodes offers the Q-suffix automotive-grade variant (e.g., D24V0X1B2LPQ-7B) for PPAP-required applications.
How does the 0.5pF capacitance impact USB 3.0 Gen 1 signal integrity?
At 0.5pF, the device introduces negligible capacitive loading on SuperSpeed differential pairs, preserving impedance continuity and minimizing return loss below −15dB up to 2.5GHz. Measured eye diagrams show no measurable jitter or amplitude degradation at 5Gbps data rates.
Is reflow soldering supported for the X1-DFN1006-2 package?
Yes - the package is qualified for standard lead-free reflow profiles (J-STD-020 Level 1), with peak temperatures up to 260°C. Recommended profile includes ramp rate ≤3°C/s, preheat 150–200°C for 60–120s, and time above liquidus 60–90s at 235–245°C.
