Product details
Overview
D24V0L1B2LP-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 24V reverse standoff voltage, ±20kV IEC 61000-4-2 contact/air ESD rating, 6pF typical channel capacitance, and 2A peak pulse current capability in a X1-DFN1006-2 package - enabling robust protection without signal integrity degradation in USB, audio, or camera interfaces.
For engineers reviewing the D24V0L1B2LP-7B datasheet, D24V0L1B2LP-7B pinout, D24V0L1B2LP-7B application, or D24V0L1B2LP-7B equivalent, this device is selected for compact, low-capacitance ESD clamping in space-constrained consumer interfaces where leakage (<100nA at 24V), clamping voltage (46V at 2A), and AEC-Q101 qualification are critical design constraints.
Technical Context
This TVS diode operates in bidirectional avalanche mode to clamp both positive and negative transients above its 26V minimum breakdown voltage. Its low 6pF input capacitance ensures minimal loading on high-frequency signal paths such as USB 2.0 or MIPI D-PHY interfaces.
The device uses a silicon avalanche structure with NiPdAu-plated terminals on a copper leadframe, housed in a halogen-free, RoHS-compliant molded plastic case rated UL 94V-0. Thermal resistance is 500°C/W, supporting operation from –65°C to +150°C with 250mW steady-state power dissipation on standard FR-4 PCB layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - Maximum continuous working voltage before clamping begins |
| Breakdown Voltage (min) | 26 V - Confirmed avalanche conduction threshold at 1mA test current |
| Clamping Voltage (2A) | 46 V - Peak voltage seen by protected circuit during 8/20µs surge |
| ESD Rating | ±20 kV - Full compliance with IEC 61000-4-2 contact and air discharge |
| Channel Capacitance | 6 pF - Measured at 0V bias, 1MHz; preserves signal integrity up to ~1GHz |
| Leakage Current | 100 nA - Max reverse current at 24V; avoids battery drain in always-on ports |
| Package | X1-DFN1006-2 - 1.08 × 0.68 mm footprint, 0.53 mm max height for ultra-thin assemblies |
Pinout & Package
Package: X1-DFN1006-2 - ultra-compact, dual-terminal, side-wettable flank package optimized for optical solder-joint inspection and automated optical inspection (AOI) after reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Transient current sink for negative excursions | Bidirectional clamping node; connects to protected line (e.g., USB D+) |
| Cathode (Pin 2) | Transient current sink for positive excursions | Same physical terminal as Anode in symmetric DFN layout; forms single-channel bidirectional path |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD protection | Single-channel architecture clamps ± transients without polarity dependency - simplifies routing on differential pairs |
| Low-profile DFN package | 0.53 mm max height enables use in <1.0 mm total stack-up mobile designs (e.g., foldable phone flex circuits) |
| Optical inspection support | Side-wettable flanks allow post-reflow AOI verification of solder fillet quality - reduces field failure risk |
| AEC-Q101 qualified | Validated for automotive infotainment and telematics interfaces requiring extended temperature and reliability assurance |
Applications
| USB 2.0 Interface Protection | Smartphone Camera Module |
|---|---|
Use Scenario: Protecting USB D+/D− lines against ESD events during cable insertion/removal in handheld devices. IC Role / Device Role / Timing Role: Bidirectional clamping diode placed directly at connector entry point to shunt transients before reaching PHY IC. Use Value: 6pF capacitance avoids signal rise-time degradation; 46V clamping prevents PHY latch-up or damage under 2A surge. | Use Scenario: Shielding MIPI CSI-2 data lanes in rear-facing camera modules from handling ESD during assembly and end-user operation. IC Role / Device Role / Timing Role: Single-channel TVS per data lane, mounted adjacent to image sensor connector to minimize trace inductance. Use Value: Low leakage (<100nA) eliminates DC offset errors; AEC-Q101 qualification supports automotive camera deployment. |
| Portable Audio Jack | Laptop HDMI Port |
Use Scenario: Guarding 3.5mm TRRS audio jack contacts (mic, left/right, ground) against user-handling ESD in headphones and earbuds. IC Role / Device Role / Timing Role: One D24V0L1B2LP-7B per active contact, leveraging bidirectional symmetry to avoid polarity assignment errors. Use Value: 24V standoff matches typical audio bias rails; side-wettable flanks enable AOI on dense front-panel PCBs. | Use Scenario: Protecting HDMI TMDS clock and data channels from ESD during hot-plug events in ultrabooks and docking stations. IC Role / Device Role / Timing Role: TVS placed at port edge with minimal stub length to preserve 1.65 GHz signal bandwidth. Use Value: 6pF capacitance meets HDMI 1.4/2.0 AC-coupled channel requirements; 26–32V VBR ensures no false triggering during common-mode swings. |
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 | Unidirectional, SMA package (4.5 × 2.7 mm), 500W PPP, 13.3pF CT | Requires external polarity management; unsuitable for differential or space-constrained layouts | Select only when higher surge rating (>2A) is required and board area permits larger footprint |
| SP1003-02HTG | Bi-directional, SOD-923 (1.0 × 0.6 mm), 12pF CT, ±15kV ESD | Lower ESD rating and higher capacitance limit use in >480 Mbps interfaces | Prefer for cost-sensitive non-automotive applications where 15kV ESD suffices and 12pF is acceptable |
Compared with SMAJ24A-Q and SP1003-02HTG, D24V0L1B2LP-7B uniquely balances ultra-small size (1.08 × 0.68 mm), low 6pF capacitance, full ±20kV ESD immunity, and AEC-Q101 qualification - making it optimal for next-gen mobile and automotive infotainment interfaces demanding minimal board impact and maximum reliability.

FAQ
What is the maximum operating temperature for D24V0L1B2LP-7B?
The device is rated for continuous operation from –65°C to +150°C ambient temperature. Its thermal resistance (RθJA = 500°C/W) assumes mounting on a standard FR-4 PCB with Diodes' recommended pad layout; derating applies above +25°C per Figure 2 in the datasheet.
Does D24V0L1B2LP-7B require orientation during placement?
No - it is a symmetric bidirectional device in a two-terminal DFN package. Both terminals are functionally identical for clamping; no anode/cathode orientation is needed during PCB layout or pick-and-place, simplifying assembly and reducing misplacement risk.
How does the side-wettable flank feature improve manufacturing yield?
The NiPdAu-plated sidewalls enable automated optical inspection (AOI) of solder fillets after reflow. This allows real-time detection of insufficient solder, bridging, or voiding - critical for zero-defect assembly in high-density portable PCBs where traditional X-ray inspection is impractical.
Can D24V0L1B2LP-7B be used in automotive ADAS camera systems?
Yes - it is AEC-Q101 qualified and rated for –65°C to +150°C operation. Its 6pF capacitance and 46V clamping voltage meet MIPI CSI-2 requirements for 1.5 Gbps camera links, and its halogen-free, green construction complies with automotive material restrictions.
