Product details
Overview
D24V0F2U3WQ-7 from Diodes Incorporated is a 2-channel low-capacitance TVS diode array designed for ESD protection of high-speed data lines in automotive infotainment systems. It features a 24 V reverse standoff voltage, 27 V minimum breakdown voltage, 0.8 pF typical channel capacitance, ±10 kV contact/±15 kV air ESD rating per IEC 61000-4-2, and AEC-Q101 qualification.
For engineers reviewing the D24V0F2U3WQ-7 datasheet, D24V0F2U3WQ-7 pinout, D24V0F2U3WQ-7 application, or D24V0F2U3WQ-7 equivalent, this device is selected for USB 2.0 and HDMI interface protection where sub-1 pF capacitance, low clamping voltage (45 V at 2.5 A), and automotive-grade reliability are required.
Technical Context
This dual-channel TVS array uses bidirectional avalanche diode structures configured between each I/O line and ground (VSS) to clamp transient overvoltages while maintaining signal integrity. Its SOT323 package supports compact PCB layouts for space-constrained automotive modules.
The device operates within –55°C to +150°C, with thermal resistance of 500°C/W and power derating above 25°C ambient. It delivers 2.5 A peak pulse current (8/20 µs) and clamps to ≤45 V under 2.5 A surge, enabling robust protection without signal distortion on high-speed interfaces.
Key Specifications

Applications
| USB 2.0 Interface Protection | HDMI DDC/CEC Line Protection |
|---|---|
Use Scenario: Protecting USB 2.0 data lines (D+/D−) in automotive head units against ESD events during cable insertion or user handling. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at connector, shunting ESD energy to ground before reaching USB PHY. Use Value: 0.8 pF capacitance avoids signal degradation; 45 V clamping prevents PHY latch-up or damage during ±15 kV air discharge. | Use Scenario: Safeguarding HDMI Display Data Channel (DDC) and Consumer Electronics Control (CEC) lines in infotainment displays from ESD coupling via cables. IC Role / Device Role / Timing Role: Low-capacitance TVS array connected between DDC clock/data lines and chassis ground to suppress fast transients without affecting 100 kHz DDC signaling. Use Value: Sub-1 pF loading maintains timing margin on 5 V open-drain DDC bus; AEC-Q101 ensures long-term reliability in vehicle temperature cycles. |
| Automotive Infotainment Console | Telematics Module I/O Protection |
Use Scenario: Integrated into central infotainment console PCBs to protect multiple high-speed interfaces (USB, HDMI, SD card) from repeated ESD exposure in passenger cabins. IC Role / Device Role / Timing Role: Dual-channel discrete TVS providing localized, per-line protection adjacent to connectors-reducing trace inductance and improving clamping response. Use Value: SOT323 footprint minimizes board area; 27 V breakdown aligns with 24 V system rail margins; qualified for 15-year automotive service life. | Use Scenario: Shielding CAN-FD or cellular modem I/O pins in telematics control units (TCUs) from ESD induced through antenna or diagnostic ports. IC Role / Device Role / Timing Role: Secondary-level ESD protection stage after common-mode chokes, absorbing residual surges that bypass front-end filtering. Use Value: 2.5 A peak pulse rating handles multi-event stress; low dynamic resistance (0.9 Ω) ensures rapid voltage collapse during transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel low-capacitance TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J24A-Q | Single-channel, 24 V standoff, 300 W peak power, 12 pF capacitance | Higher capacitance limits use to lower-speed interfaces (e.g., LIN, UART); not suitable for USB/HDMI. | Select only when protecting non-high-speed lines where board space allows larger SMA package. |
| SP1003-02UTG | 2-channel, 24 V standoff, 0.3 pF capacitance, 12 A IPP, no AEC-Q101 qualification | Lacks automotive qualification and has higher clamping voltage (53 V at 12 A); suited for consumer portable electronics. | Prefer for cost-sensitive non-automotive designs requiring ultra-low capacitance; avoid in production automotive ECUs. |
Compared with SMA6J24A-Q and SP1003-02UTG, D24V0F2U3WQ-7 uniquely balances automotive qualification, sub-1 pF capacitance, and 2.5 A surge capability in a 2.2 mm² SOT323 footprint-making it optimal for space-constrained, safety-critical infotainment interfaces.

FAQ
What is the maximum operating temperature for D24V0F2U3WQ-7?
The device operates from –55°C to +150°C, with thermal resistance of 500°C/W. Its power derating curve shows linear reduction in peak pulse capability above 25°C ambient, maintaining full 2.5 A rating up to 75°C ambient when mounted on standard FR-4 with recommended pad layout.
Is D24V0F2U3WQ-7 compatible with lead-free reflow soldering processes?
Yes. The device uses matte tin-finished alloy 42 lead frames and is rated for lead-free reflow per JEDEC J-STD-020. Its moisture sensitivity level is 1, eliminating bake requirements prior to assembly. The SOT323 package withstands peak temperatures up to 260°C for 10 seconds.
How does D24V0F2U3WQ-7 differ from single-channel TVS diodes in USB protection?
Unlike single-channel devices, D24V0F2U3WQ-7 integrates two matched, low-capacitance TVS paths in one SOT323 package-reducing PCB area by ~40% and ensuring identical electrical characteristics across D+ and D− lines. This eliminates inter-channel skew and simplifies layout for differential signal pairs.
Can D24V0F2U3WQ-7 be used for HDMI TMDS line protection?
Yes, it is explicitly recommended for HDMI inputs in the datasheet. With 0.8 pF capacitance and 45 V clamping at 2.5 A, it preserves TMDS signal integrity at 1.65 Gbps while meeting IEC 61000-4-2 Level 4 ESD immunity-validated in Diodes' AN77 application note for USB 2.0 and HDMI interfaces.
