Product details
Overview
D24V0S1B2TQ from Diodes Incorporated is a single-channel bidirectional TVS diode designed for ESD protection of high-speed data lines. It features a 24V reverse standoff voltage, 28.9V minimum breakdown voltage, 40V clamping voltage at 1A, 17.3pF channel capacitance, and ±22kV contact/±25kV air ESD rating per IEC 61000-4-2 - ideal for HDMI and USB interface protection in portable electronics.
For engineers reviewing the D24V0S1B2TQ datasheet, D24V0S1B2TQ pinout, D24V0S1B2TQ application, or D24V0S1B2TQ equivalent, key selection criteria include low signal-line capacitance for high-speed integrity, AEC-Q101 qualification for automotive-grade reliability, and SOD523 footprint compatibility with space-constrained PCB layouts.
Technical Context
This TVS operates bidirectionally to clamp transient overvoltages above ±28.9V while maintaining low leakage (<200nA at 24V) and minimal capacitive loading on signal paths. Its 17.3pF input capacitance enables use on 480Mbps USB 2.0 and 1080p HDMI channels without signal degradation.
The device delivers 360W peak pulse power handling (8/20μs waveform) with a 40V clamping voltage at 1A surge current, and is rated for operation from –55°C to +150°C - supporting deployment in automotive infotainment and industrial display interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24V - Maximum continuous operating voltage before conduction begins |
| Breakdown Voltage (Min) | 28.9V - Guaranteed conduction onset under ESD stress, ensuring early clamping |
| Clamping Voltage (1A) | 40V - Peak voltage seen by protected IC during 1A 8/20μs surge |
| Channel Capacitance | 17.3pF - Low enough to avoid signal integrity loss on HDMI/USB 2.0 lines |
| ESD Rating (Contact) | ±22kV - Meets IEC 61000-4-2 Level 4 for robust system-level ESD immunity |
| Package | SOD523 - 1.25mm × 0.85mm surface-mount footprint for ultra-compact layout |
| Operating Temp Range | –55°C to +150°C - Validated for under-hood automotive and industrial environments |
Pinout & Package
Package: SOD523 - ultra-small plastic molded case (1.25mm × 0.85mm × 0.65mm), matte tin-plated alloy 42 lead-frame, RoHS-compliant, halogen-free, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Cathode Mark Side) | Signal Line Terminal A | Bidirectional conduction path - connects to one side of differential or single-ended data line |
| Cathode (Marked End) | Signal Line Terminal B | Completes symmetrical clamping path - enables equal ±VBR response across both polarities |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Clamping | Enables symmetric protection of AC-coupled or differential signals (e.g., HDMI TMDS pairs) without polarity constraints |
| AEC-Q101 Qualified | Validated for automotive applications including infotainment displays and camera modules requiring PPAP documentation |
| Low 17.3pF Capacitance | Preserves signal rise/fall times on 480Mbps USB 2.0 and 1.65Gbps HDMI 1.4 channels |
| ±25kV Air / ±22kV Contact ESD | Exceeds IEC 61000-4-2 Level 4 - reduces need for secondary board-level protection |
| SOD523 Footprint | Minimizes PCB area vs. SOD323/SOT23 - critical for thin-profile mobile and automotive display connectors |
Applications
| HDMI Interface Protection | USB 2.0 Port Protection |
|---|---|
Use Scenario: Protecting HDMI 1.4 TMDS differential pairs in automotive head units against connector hot-plug transients and ESD events. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at HDMI receptacle, clamping surges before they reach the source/sink PHY. Use Value: 17.3pF capacitance avoids skew between TMDS+/- lines; 40V clamping ensures downstream SerDes remains below absolute maximum ratings. | Use Scenario: Shielding USB 2.0 D+/D− lines in portable medical monitors from ESD during cable insertion/removal. IC Role / Device Role / Timing Role: Single-channel TVS placed inline on each data line, providing fast-response clamping without affecting 480Mbps signaling integrity. Use Value: ±22kV contact ESD rating meets IEC 61000-4-2 compliance for handheld clinical devices; SOD523 size fits tight connector keep-out zones. |
| Automotive Camera Link Protection | LVDS Display Interface Protection |
Use Scenario: Safeguarding MIPI CSI-2 or FPD-Link III camera data lanes in ADAS rearview cameras exposed to harsh vehicle environments. IC Role / Device Role / Timing Role: TVS deployed per-lane at camera module flex-to-PCB interface, suppressing ESD induced by chassis discharge paths. Use Value: AEC-Q101 qualification confirms reliability under thermal cycling (-40°C to +105°C ambient); low capacitance prevents jitter accumulation in 1.5Gbps links. | Use Scenario: Protecting LVDS clock and data pairs driving TFT displays in industrial HMIs subject to frequent operator touch and static buildup. IC Role / Device Role / Timing Role: Bidirectional clamping device placed adjacent to display connector, limiting transient energy coupled onto balanced differential traces. Use Value: 28.9V VBR ensures no conduction during normal 24V rail operation; 40V clamping protects LVDS receivers rated to 5.5V absolute max. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24CA | DO-214AC package (4.5mm × 2.7mm), 400W PPP, 52V clamping at 6A | Higher clamping voltage and larger footprint - suitable only where board space and signal speed are less constrained | Select when higher surge margin is needed and 17.3pF capacitance is not required |
| TPD2E001DRYR | 2-channel array in X2SON-6, 12pF/channel, ±8kV contact ESD, non-AEC-Q101 | Lower ESD rating and dual-channel configuration - optimized for cost-sensitive consumer USB ports, not automotive | Choose for multi-line protection in non-automotive USB hubs where footprint efficiency outweighs ESD margin |
Compared with SMAJ24CA and TPD2E001DRYR, D24V0S1B2TQ uniquely balances ultra-low capacitance, AEC-Q101 qualification, and compact SOD523 packaging - making it the only option validated for high-speed automotive display and camera interfaces requiring <20pF loading and full automotive change control.

FAQ
What is the maximum clamping voltage of D24V0S1B2TQ under a 6A 8/20μs surge?
The datasheet does not specify clamping voltage at 6A; it provides VCL = 40V at 1A (8/20μs). At 6A, clamping rises nonlinearly - typical values for this family exceed 60V. For design margin, use the 40V value at 1A and verify system-level protection with worst-case surge modeling.
Can D24V0S1B2TQ be used on a 3.3V logic line?
No - its 24V reverse standoff voltage and 28.9V minimum breakdown make it unsuitable for 3.3V systems. It is intended for 24V nominal interfaces like automotive display links or industrial I/O. For 3.3V lines, select a TVS with VRWM ≤ 3.6V (e.g., D3V3S1BA).
Does D24V0S1B2TQ require external biasing or control signals?
No - it is a passive, two-terminal device. No biasing, enable pins, or control circuitry is needed. It operates automatically: conducting only during overvoltage events exceeding its breakdown threshold, remaining high-impedance otherwise.
How does the SOD523 package affect thermal performance in continuous operation?
Its 350°C/W junction-to-ambient thermal resistance limits continuous power dissipation to 450mW at 25°C ambient. In real-world PCB layouts with 2oz copper, derating begins above 75°C ambient - consult Figure 1 in DS41310 for precise power derating curves before deploying in sealed enclosures.
