Product details
Overview
D1213A-04VQ from Diodes Incorporated is a 4-channel low-capacitance TVS diode array designed for ESD protection of high-speed data lines. It features 6 V reverse breakdown voltage, ±25 kV IEC 61000-4-2 contact/air ESD rating, 0.85 pF typical channel input capacitance, and AEC-Q101 qualification-making it suitable for automotive HDMI, USB 2.0, and LVDS interfaces.
For engineers reviewing the D1213A-04VQ datasheet, D1213A-04VQ pinout, D1213A-04VQ application, or D1213A-04VQ equivalent, key selection criteria include clamping voltage under 10 V at 1 A, sub-1 pF capacitance for signal integrity, dual-rail (VP/VN) architecture, and SOT563 package compatibility with space-constrained PCB layouts.
Technical Context
This device implements a dual-rail TVS architecture with four bidirectional channels referenced between VP (positive supply rail) and VN (negative/ground rail). Each channel integrates matched top and bottom diodes to clamp both positive and negative transients symmetrically without requiring external bias.
Its low dynamic resistance (0.9 Ω) and fast response time ensure effective suppression of ESD pulses per IEC 61000-4-2 while maintaining signal fidelity on differential or single-ended high-speed links operating up to 480 Mbps (USB 2.0).
Key Specifications

| IPP Max | 5.0 A (8/20 µs) - Withstands automotive-level surge events without degradation. |
| CIN Typ | 0.85 pF - Enables use on USB 2.0, HDMI, and LVDS without measurable signal distortion. |
| VCL1 / VCL2 | 10.0 V / −1.7 V at 1 A - Limits transient overvoltage to safe levels for connected PHY ICs. |
| ESD Rating | ±25 kV air/contact - Meets highest IEC 61000-4-2 immunity requirement for end-equipment certification. |
| Operating Temp | −55 °C to +150 °C - Supports under-hood and infotainment module deployment in automotive environments. |

| 4 (CH4) | Channel 4 Anode/Cathode Node | Fourth protected line (e.g., LVDS positive/negative pair element). |

IC Role / Device Role / Timing Role: Four-channel ESD protector placed at camera flex-cable entry point, referenced to local power rails. Use Value: Avoids false frame drops or sensor reset events triggered by ESD-induced common-mode noise on differential lines. |
Use Scenario: Securing display data bus (e.g., eDP or FPD-Link III) in medical panel PCs where repeated cable mating occurs. IC Role / Device Role / Timing Role: High-density TVS array protecting multiple high-speed serial lanes within tight board space constraints. Use Value: Enables CE/IEC 60601-1-2 ESD immunity compliance without sacrificing display resolution or refresh rate. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1006-04UTG | Higher CIN (1.2 pF typ), same ±25 kV ESD rating, SOT563 package. | Marginally reduced bandwidth margin on 480 Mbps USB 2.0; acceptable for HDMI 1.3. | Prefer when cost sensitivity outweighs sub-1 pF requirement and legacy design reuse is prioritized. |
| ESD7L5.0DT5G | Single-channel, 5.0 V VBR, 0.6 pF CIN, SOD-523 package. | Requires 4× placement for quad protection; lacks integrated VP/VN rails. | Select only when board layout allows discrete placement and tighter capacitance budget (<0.7 pF) is mandatory. |
Compared with SP1006-04UTG and ESD7L5.0DT5G, D1213A-04VQ uniquely delivers quad-channel integration, 0.85 pF capacitance, and dual-rail architecture in one SOT563 footprint-reducing component count, layout complexity, and risk of mismatched channel performance in automotive data interfaces.

FAQ
What is the maximum clamping voltage for D1213A-04VQ during a 1 A ESD event?
The D1213A-04VQ clamps positive transients to 10.0 V and negative transients to −1.7 V at 1 A (8/20 µs waveform), as specified in its electrical characteristics table. This ensures downstream 3.3 V or 5 V ICs remain within absolute maximum ratings during standardized ESD strikes.
Can D1213A-04VQ be used on 5 V USB 2.0 lines without DC biasing?
Yes-its dual-rail architecture uses VP and VN terminals to establish internal bias; no external resistors or voltage dividers are needed. When VP = 5 V and VN = 0 V, the device provides symmetrical clamping centered around 2.5 V, fully compatible with 5 V-tolerant USB 2.0 transceivers.
Is the SOT563 package of D1213A-04VQ compatible with standard reflow profiles?
Yes-the SOT563 package is rated for moisture sensitivity level 1 (MSL-1) and supports JEDEC J-STD-020-compliant reflow profiles, including peak temperatures up to 260 °C. Its matte tin finish ensures reliable solder wetting on FR-4 PCBs with standard 2 oz copper pads.
Does D1213A-04VQ require derating at elevated ambient temperatures?
Yes-power dissipation must be derated linearly above 25 °C ambient, per Figure 1 in the datasheet. At 125 °C ambient, maximum allowable power drops to approximately 120 mW (32% of 380 mW rating), which remains sufficient for transient-only ESD protection duty cycles.
