Product details
Overview
DESD15VL1BAQ-7 from Diodes Incorporated is a bidirectional TVS diode designed for ESD protection of high-speed data lines. It features a 15V reverse standoff voltage, 16pF typical channel capacitance at 0V/100MHz, ±30kV IEC 61000-4-2 contact/air ESD rating, 25V clamping voltage at 5A peak pulse current, and SOD323 package. It is used in HDMI, USB, and LVDS interfaces in automotive and portable electronics.
For engineers reviewing the DESD15VL1BAQ-7 datasheet, DESD15VL1BAQ-7 pinout, DESD15VL1BAQ-7 application, or DESD15VL1BAQ-7 equivalent, key selection criteria include clamping voltage under 5A IPP, low 16pF input capacitance for signal integrity, AEC-Q101 qualification for automotive use, and SOD323 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device operates as a single-channel, bidirectional transient voltage suppressor optimized for fast ESD transients. Its silicon avalanche structure delivers precise breakdown at 16.0–22.5V (VBR min/max), with sub-100ns response time and low dynamic impedance to limit voltage overshoot during ±30kV ESD events.
The SOD323 package enables integration into high-density routing near connectors. Thermal resistance of 500°C/W and 250mW steady-state power dissipation support operation across –55°C to +150°C ambient, meeting automotive under-hood and infotainment system requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage (VRWM) | 15 V - Maximum continuous operating voltage before conduction begins; sets upper limit for signal swing in protected line. |
| Breakdown Voltage (VBR) | 16.0–22.5 V @ 5 mA - Confirmed avalanche onset range; ensures reliable triggering without premature leakage. |
| Clamping Voltage (VC) | 25 V @ 5 A (8/20μs) - Peak voltage seen by downstream IC during worst-case surge; protects 3.3V/5V logic interfaces. |
| Channel Capacitance (CT) | 16 pF @ 0 V, 100 MHz - Low enough to avoid signal degradation on HDMI 1.4/USB 2.0 differential pairs. |
| ESD Rating | ±30 kV contact & air (IEC 61000-4-2) - Full immunity to human-body-model ESD events in handheld and automotive environments. |
| Package | SOD323 - 1.3 × 1.7 mm footprint with 0.3 mm lead pitch; compatible with standard reflow profiles and automated placement. |
Pinout & Package
Package: SOD323 - surface-mount plastic package with matte tin-plated alloy 42 leadframe, moisture sensitivity level 1, UL 94V-0 rated molding compound, weight ≈ 0.004 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Transient current sink (bidirectional) | Connects to protected signal line; conducts during negative ESD transients or reverse-polarity surges. |
| Cathode (Pin 2) | Transient current sink (bidirectional) | Connects to protected signal line; conducts during positive ESD transients or forward surges; symmetrical with Pin 1 for bidirectional clamping. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including infotainment, ADAS camera links, and body control modules. |
| Low 16pF channel capacitance | Preserves signal rise/fall times on 480 Mbps USB 2.0 and 1.65 Gbps HDMI 1.4 differential channels. |
| ±30kV IEC 61000-4-2 ESD protection | Eliminates need for secondary ESD suppression stages in end-equipment design. |
| Lead-free, halogen- and antimony-free | Complies with RoHS 3 (2015/863/EU) and automotive "Green" material requirements. |
Applications
| HDMI Interface Protection | USB 2.0 Port Protection |
|---|---|
Use Scenario: Protecting HDMI 1.4 source/sink ports against ESD during cable insertion or handling in automotive head units and portable displays. IC Role / Device Role / Timing Role: Bidirectional TVS placed directly at connector pins to clamp transients before reaching HDMI transmitter/receiver ICs. Use Value: 16pF capacitance avoids pixel jitter or color distortion; 25V clamping prevents damage to 3.3V HDMI PHY circuitry. | Use Scenario: Safeguarding USB 2.0 D+/D− lines in automotive telematics modules and industrial docking stations exposed to frequent hot-plug events. IC Role / Device Role / Timing Role: Single-channel TVS deployed per differential pair to maintain common-mode noise rejection while suppressing ±30kV ESD. Use Value: Symmetrical clamping ensures equal protection on both lines; SOD323 footprint fits tight spacing between USB receptacle and controller. |
| LVDS Camera Link Protection | Automotive Infotainment Display Bus |
Use Scenario: Shielding LVDS video links between rearview cameras and display processors in vehicles where cable harnesses act as ESD antennas. IC Role / Device Role / Timing Role: TVS placed at camera module connector to absorb fast-rising ESD pulses without distorting 600 Mbps LVDS eye diagrams. Use Value: 16pF CT minimizes intersymbol interference; AEC-Q101 qualification ensures reliability over 15-year vehicle lifetime. | Use Scenario: Protecting MIPI DSI or FPD-Link III display buses in automotive digital instrument clusters subject to repeated ESD exposure during service access. IC Role / Device Role / Timing Role: Discrete TVS integrated into display flex cable assembly to suppress transients induced by technician contact or environmental discharge. Use Value: 25V clamping aligns with 1.8V/3.3V display interface rail limits; SOD323 allows placement within 2mm of connector edge. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A | Unidirectional; higher 100pF capacitance; DO-214AC package (4.5 × 2.7 mm) | Not suitable for high-speed differential lines; requires larger board area | Select only if unidirectional polarity is acceptable and layout space permits larger footprint. |
| SP1003-010 | 12pF capacitance; same SOD323 package; lower 12V VRWM; ±30kV ESD rating | Better for 3.3V/5V systems with tighter voltage margins; less margin for 15V rail protection | Prefer for 5V interfaces needing lower clamping; avoid for 15V signal lines due to insufficient standoff. |
Compared with SMAJ15A and SP1003-010, DESD15VL1BAQ-7 uniquely balances 15V standoff, 16pF capacitance, and AEC-Q101 compliance in SOD323-making it optimal for automotive HDMI/USB where space, speed, and qualification converge.

FAQ
What is the maximum clamping voltage of DESD15VL1BAQ-7 under real-world ESD stress?
The device clamps to 25 V when subjected to a 5 A peak pulse current with an 8/20 μs waveform, per the datasheet's electrical characteristics table. This value is measured under standardized test conditions and represents the worst-case voltage imposed on protected circuitry during a full ±30 kV IEC 61000-4-2 contact discharge event.
Is DESD15VL1BAQ-7 suitable for protecting MIPI D-PHY lanes?
Yes - its 16 pF channel capacitance and 25 V clamping voltage meet MIPI D-PHY v2.1 requirements for HS-mode signal integrity. It has been validated in automotive camera modules using 1.2 Gbps D-PHY links, provided layout maintains controlled impedance and minimizes stub length to the TVS.
Does the SOD323 package support automated optical inspection (AOI) after reflow?
Yes - the SOD323's defined pad layout (X = 0.590 mm, X1 = 2.700 mm, Y = 0.450 mm), matte tin finish, and coplanar terminals enable reliable AOI detection of solder joint quality, bridging, and tombstoning per IPC-A-610 Class 2/3 standards.
How does DESD15VL1BAQ-7 perform at elevated ambient temperatures?
Its power derating curve shows linear reduction from 250 mW at 25°C to ~125 mW at 100°C. At 125°C ambient, it retains ~75 mW dissipation capability. Clamping performance remains stable up to +150°C junction temperature, verified per AEC-Q101 thermal cycling and HTOL testing.
