Product details
Overview
D24V0L1B2LPSQ-7B from Diodes Incorporated is a bidirectional transient voltage suppression (TVS) diode designed for ESD protection of high-speed data lines in automotive-grade portable electronics. It features a 24V reverse standoff voltage, ±20kV IEC 61000-4-2 contact/air ESD rating, 6pF typical channel capacitance, and U-DFN1006-2/SWP package - enabling robust protection in space-constrained interfaces like USB 2.0 or HDMI signal paths.
For engineers reviewing the D24V0L1B2LPSQ-7B datasheet, D24V0L1B2LPSQ-7B pinout, D24V0L1B2LPSQ-7B application, or D24V0L1B2LPSQ-7B equivalent, key selection criteria include clamping voltage at 2A (46V), thermal resistance (500°C/W), AEC-Q101 qualification, low-profile footprint (1.08 × 0.68 mm), and automotive-compliant marking (SG).
Technical Context
This TVS diode operates as a bidirectional clamping device with symmetrical breakdown behavior (VBR = 26–32V @ 1mA), delivering fast response to ESD transients while maintaining minimal signal distortion on high-frequency lines. Its low 6pF input capacitance ensures <0.5dB insertion loss up to 500MHz, and the U-DFN1006-2/SWP package supports optical solder-joint inspection via sidewall plating.
The device complies with AEC-Q101 stress testing for automotive applications and sustains 90W peak pulse power (8/20µs waveform) with a clamping voltage of 42V at 1A and 46V at 2A. Thermal derating follows a linear curve down to 0% power at +150°C ambient, per Figure 2 in DS36505 Rev. 2-2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - Maximum continuous operating voltage before conduction begins; sets safe margin below system rail. |
| Breakdown Voltage (VBR) | 26–32 V @ 1mA - Confirmed symmetric triggering threshold for bidirectional ESD clamping. |
| Clamping Voltage (VCL) | 46 V @ 2A, 8/20µs - Peak voltage seen by protected IC during worst-case surge; limits stress on downstream logic. |
| Channel Capacitance (CT) | 6 pF (typ) @ 0V, 1MHz - Enables use on USB 2.0 (480 Mbps) and other high-speed digital interfaces without signal integrity loss. |
| ESD Rating | ±20 kV contact & air (IEC 61000-4-2) - Meets automotive infotainment and telematics ESD immunity requirements. |
| Package | U-DFN1006-2/SWP - 1.08 × 0.68 mm footprint with sidewall plating for post-reflow optical inspection. |
| Thermal Resistance (RθJA) | 500 °C/W - Based on FR-4 PCB with AP02001 pad layout; defines maximum power dissipation at elevated ambient temperatures. |
Pinout & Package
U-DFN1006-2/SWP is a 2-terminal, bottom-terminal surface-mount package with exposed copper pads on the underside and sidewall plating for automated optical inspection. Pin 1 identification is marked by seating plane offset per AP02002 outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode (bidirectional) | Shared terminal for both polarities; connects to protected line (e.g., USB D+). |
| Terminal 2 | Cathode (bidirectional) | Shared terminal for both polarities; connects to ground reference plane. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive temperature range (−65°C to +150°C) and mechanical stress testing per JESD22 standards. |
| Optical inspection enabled | Sidewall plating on U-DFN1006-2/SWP allows AOI verification of solder fillet integrity after reflow. |
| Ultra-low profile | 0.53 mm max height - fits under stacked connectors and within tight Z-axis constraints of automotive head units. |
| Halogen & antimony free | Meets "Green" definition: Br & Cl <900 ppm each, total Br+Cl <1500 ppm, Sb <1000 ppm. |
| Lead-free & RoHS compliant | Fully compliant with EU Directive 2011/65/EU; NiPdAu over copper leadframe ensures MIL-STD-202 solderability. |
Applications
| USB 2.0 Interface Protection | HDMI Signal Line Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines in automotive infotainment USB host ports against ESD events during cable insertion. IC Role / Device Role / Timing Role: Bidirectional clamping TVS placed directly at connector entry point to shunt ESD current to chassis ground. Use Value: 6pF capacitance preserves eye diagram integrity at 480 Mbps; 46V clamping prevents damage to USB PHY transceivers rated for ≤5.5V supply. | Use Scenario: Safeguarding TMDS clock and data pairs in rear-seat entertainment HDMI receivers from user-handling ESD. IC Role / Device Role / Timing Role: Low-capacitance TVS mounted adjacent to HDMI connector to minimize stub length and preserve signal rise time. Use Value: Symmetric 26–32V breakdown enables protection of AC-coupled differential signals without DC bias shift or common-mode disruption. |
| Automotive Camera Link Protection | Touchscreen Controller I/O Protection |
Use Scenario: Shielding MIPI CSI-2 lanes between ADAS camera module and SoC against ESD during vehicle service or environmental exposure. IC Role / Device Role / Timing Role: Single-channel TVS placed per differential pair to maintain impedance matching and reduce crosstalk-induced jitter. Use Value: 0.53 mm profile avoids interference with flex circuit bending radius; AEC-Q101 qualification ensures reliability across thermal cycling in engine bay proximity. | Use Scenario: Guarding I²C SDA/SCL and GPIO lines of capacitive touchscreen controllers in center console displays. IC Role / Device Role / Timing Role: Discrete TVS on each I/O line to prevent latch-up or gate oxide rupture during finger-contact ESD events. Use Value: 100 nA leakage at 24V standoff ensures no measurable impact on pull-up resistor networks or controller input thresholds. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-Q | Unidirectional; higher 5.0mm × 3.5mm SMA package; 500W PPP; 120pF CT | Not suitable for high-speed data lines; used only on power rails or low-frequency I/O. | Select only when board space and signal bandwidth are non-critical and unidirectional clamping suffices. |
| SP1003-02UTG | Same U-DFN1006-2 package; 24V VRWM; 12pF CT; ±30kV ESD rating; no AEC-Q101 certification | Lacks automotive qualification; higher capacitance limits use to ≤100 Mbps interfaces. | Prefer for consumer portable designs where cost and ESD margin outweigh automotive compliance needs. |
Compared with SMAJ24A-Q and SP1003-02UTG, D24V0L1B2LPSQ-7B uniquely combines AEC-Q101 qualification, 6pF capacitance, and 1.08 × 0.68 mm footprint - making it the only option validated for automotive high-speed serial interfaces requiring both space efficiency and functional safety alignment.

FAQ
What is the difference between D24V0L1B2LPSQ-7B and the non-automotive D24V0L1B2LPS-7B?
The Q-suffix variant is fully AEC-Q101 qualified and marked with "SG" for automotive traceability, whereas the standard version lacks stress-test validation for automotive temperature cycling, humidity, and mechanical shock. Both share identical electrical specs and packaging, but only the Q version is approved for use in automotive ECUs, infotainment, and ADAS modules per OEM requirements.
Can D24V0L1B2LPSQ-7B be used on 3.3V or 5V logic lines?
Yes - its 24V reverse standoff voltage provides ample margin above 3.3V/5V rails, ensuring no leakage or conduction during normal operation. The 26–32V breakdown threshold guarantees clamping only during ESD transients, preserving signal integrity and avoiding false triggering on nominal logic levels.
Does this TVS require external series impedance for optimal ESD performance?
No external resistor is required. The device is designed for direct placement between signal line and ground. However, minimizing PCB trace inductance (<2 mm) between TVS terminals and the protected node is critical to achieve sub-nanosecond response and avoid voltage overshoot during ±20kV ESD events.
Is the U-DFN1006-2/SWP package compatible with standard reflow profiles?
Yes - it is rated for moisture sensitivity level 1 (MSL-1) per J-STD-020 and supports standard Pb-free reflow profiles (peak 260°C). The NiPdAu-plated terminals ensure reliable wetting, and sidewall plating enables post-reflow AOI without X-ray inspection.
