Product details
Overview
D1213A-04V-7 from Diodes Incorporated is a 4-channel low-capacitance TVS diode array designed for ESD protection of high-speed data lines, featuring ±15 kV air/±8 kV contact IEC 61000-4-2 compliance, 0.85 pF typical channel capacitance, 6.0 V reverse breakdown voltage, and SOT563 package. It is deployed in USB 2.0, HDMI, DVI, and SATA interfaces to preserve signal integrity while suppressing transient overvoltages.
For engineers reviewing the D1213A-04V-7 datasheet, D1213A-04V-7 pinout, D1213A-04V-7 application, or D1213A-04V-7 equivalent, key selection criteria include channel count, clamping voltage under 1 A (10.0 V positive / –1.7 V negative), dynamic resistance (0.9 Ω), leakage current (<1.0 μA at 5 V), and thermal resistance (327 °C/W) for board-level reliability in compact high-speed layouts.
Technical Context
This device implements a bidirectional rail-to-rail TVS architecture with four independent channels, each comprising stacked top (anode-to-VP) and bottom (cathode-to-VN) diodes. It operates between VP and VN supply rails, enabling symmetric clamping for both positive and negative transients without external biasing.
Its low 0.85 pF input capacitance minimizes signal distortion on differential or single-ended high-speed buses, while the 6.0 V VBR ensures compatibility with 3.3 V and 5 V logic systems. The SOT563 package supports dense routing with 0.5 mm pitch and meets AEC-Q101 for automotive-grade robustness.
Key Specifications

|---|---|
| ESD Rating (IEC 61000-4-2) | Air ±15 kV, Contact ±8 kV - certified immunity level for system-level ESD testing |
| Channel Input Capacitance | 0.85 pF typical - preserves signal rise/fall times on USB 2.0 (480 Mbps) and HDMI 1.4 links |
| Reverse Breakdown Voltage (VBR) | 6.0 V min @ 1 mA - ensures safe margin above 5.5 V max operating supply, preventing false triggering |
| Clamping Voltage (IPP = 1 A) | +10.0 V / –1.7 V - limits transient overshoot to protect downstream PHY receivers and transmitters |
| Dynamic Resistance (RDYN) | 0.9 Ω typical - reduces voltage overshoot during fast transients by minimizing IR drop across protection path |
| Thermal Resistance (RθJA) | 327 °C/W - defines power derating slope (380 mW at 25°C ambient) on standard FR-4 PCB |
Pinout & Package
SOT563 6-pin ultra-small surface-mount package with 0.5 mm lead pitch, 1.6 mm × 1.2 mm footprint, and 0.2 mm nominal thickness. Molded green compound meets UL 94V-0 and RoHS/REACH requirements.

| 2 (CH2) | Channel 2 Anode | Input node for second protected line; electrically isolated from CH1 |
| 3 (CH3) | Channel 3 Anode | Input node for third protected line; shares common VP/VN rails with other channels |
| 4 (CH4) | Channel 4 Anode | Input node for fourth protected line; enables full-port protection in compact layout |
| 5 (VN) | Negative Supply Rail | Common cathode reference for all bottom diodes; must be connected to system ground or lowest rail |
| 6 (VP) | Positive Supply Rail | Common anode reference for all top diodes; ties to 3.3 V or 5 V supply plane |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 4-channel low-capacitance TVS diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1006-04UTG | 0.5 pF typical capacitance; lower 5.5 V VBR; 300 mW PD | Better suited for 5 Gbps USB 3.0 Gen 1 where sub-0.6 pF is critical; not AEC-Q101 qualified | Select when ultra-low capacitance outweighs automotive qualification needs |
| TPD4E001DPYR | 0.7 pF typical capacitance; 3.6 V VBR; 100 W peak pulse power | Optimized for 1.8 V/3.3 V I/O domains; higher IPP rating but larger 1.45 mm × 1.0 mm X2SON package | Prefer for mixed-voltage SoC interfaces needing tighter VBR tolerance and higher surge margin |

FAQ
What is the maximum operating voltage range for D1213A-04V-7?
The device operates with a VP–VN supply range of 6.0 V DC maximum. Its specified operating supply voltage is 3.3 V to 5.5 V, and it tolerates transient overvoltages up to ±15 kV per IEC 61000-4-2. Reverse breakdown begins at 6.0 V minimum, ensuring safe operation below this threshold in normal mode.
How does the SOT563 package affect thermal performance?
The SOT563 package delivers a thermal resistance of 327 °C/W (junction-to-ambient) on a standard 2 oz copper FR-4 PCB per Diodes' AP02001 layout. This allows 380 mW dissipation at 25°C ambient, derating linearly to ~240 mW at 85°C ambient-sufficient for typical ESD pulse energy absorption without thermal runaway.
Can D1213A-04V-7 protect bidirectional data lines like USB D+/D−?
Yes. Its rail-to-rail architecture uses stacked diodes between each channel and shared VP/VN rails, enabling symmetrical clamping for both positive and negative transients. This makes it suitable for bidirectional differential pairs such as USB 2.0 D+/D−, where polarity reversal occurs during data transmission.
Is D1213A-04V-7 compatible with lead-free reflow processes?
Yes. It features matte tin-plated copper leadframe terminals, rated for solderability per MIL-STD-202, Method 208, and qualified for standard Pb-free reflow profiles (peak temperature ≤260°C). Moisture sensitivity level is rated at Level 1 per J-STD-020, eliminating bake requirements prior to assembly.
