Product details
Overview
D1213A-02SOL from Diodes Incorporated is a dual-channel, low-capacitance TVS diode array designed for ESD protection of high-speed data lines. It features 3.3 V reverse working voltage, ±8 kV contact / ±15 kV air IEC 61000-4-2 ESD rating, and 0.85 pF typical channel capacitance at 1.65 V, enabling use in USB 2.0, HDMI, and Serial ATA interfaces.
For engineers reviewing the D1213A-02SOL datasheet, D1213A-02SOL pinout, D1213A-02SOL application, or D1213A-02SOL equivalent, key selection criteria include clamping voltage under 10 V at 1 A, sub-1 pF capacitance for signal integrity, GND-referenced dual-channel topology, and SOT23 package compatibility with high-density PCB layouts.
Technical Context
This device implements two independent bidirectional TVS diodes in a single SOT23-6 package, each referenced to a common GND terminal. Its low dynamic resistance (0.9 Ω) and fast response time ensure effective transient suppression during ESD events without signal distortion.
The array operates within -55°C to +125°C, supports 300 mW power dissipation on standard FR-4 PCBs, and maintains stable clamping performance across temperature-VCL1 ≤10.0 V at +125°C for positive transients and VCL2 ≥–1.7 V for negative transients at 1 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 2 independent ESD protection paths, each referenced to GND |
| VRWM | 3.3 V - maximum continuous DC operating voltage before leakage exceeds 1 μA |
| VBR | 6.0–9.0 V - breakdown threshold where diode begins conduction at 1 mA |
| VCL1 / VCL2 | +10.0 V / –1.7 V - clamped voltage during 1 A 8/20 μs transients, defining worst-case signal excursion |
| CT | 0.85 pF typ @ 1.65 V, 1 MHz - ensures minimal loading on 480 Mbps USB 2.0 and 1.5 Gbps SATA signals |
| IPP | 5 A - peak pulse current handling per channel, supporting multiple ESD strikes |
| ESD Rating | ±8 kV contact / ±15 kV air per IEC 61000-4-2 - meets industrial and consumer interface immunity requirements |
Pinout & Package
Package: SOT23-6 (6-pin small outline transistor), surface-mount, lead-free, RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Anode | Input node for first protected line (e.g., USB D+) |
| 2 | Channel 1 Cathode | Connected internally to GND; provides low-impedance path to ground during ESD |
| 3 | GND | Common reference and return path for both channels; must be low-inductance PCB connection |
| 4 | Channel 2 Cathode | Connected internally to GND; shares same ground node as Pin 2 |
| 5 | Channel 2 Anode | Input node for second protected line (e.g., USB D–) |
| 6 | No Connect | Unused terminal; left floating or omitted in layout per Diodes Inc. AP02001 pad design |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD protection per channel | Enables symmetric clamping for AC-coupled high-speed signals without polarity constraints |
| 0.85 pF typical capacitance | Preserves signal rise/fall times and eye diagram integrity in 480 Mbps USB 2.0 links |
| ±15 kV air / ±8 kV contact ESD rating | Exceeds IEC 61000-4-2 Level 4, qualifying for front-panel and cable-interface applications |
| SOT23-6 footprint | Reduces board area vs. discrete diode solutions while maintaining thermal performance via 417 °C/W RθJA |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel low-capacitance TVS diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1003-02UTG | 0.35 pF typ capacitance, 5.0 V VRWM, higher cost, smaller 0201 DFN package | Better suited for >1 Gbps interfaces (e.g., USB 3.0 Gen1), but requires tighter layout control | Select when signal bandwidth exceeds 1 GHz and PCB space is constrained |
| TPD2E001DRYR | Single-channel, 0.9 pF, 5.5 V VRWM, integrated 100 Ω series resistor per line | Designed for point-of-entry protection with built-in impedance matching; not pin-compatible | Prefer for new designs requiring combined ESD + series termination in one device |
Compared with SP1003-02UTG and TPD2E001DRYR, D1213A-02SOL offers balanced trade-offs: lower cost than SP1003, higher VRWM than TPD2E001, and proven reliability in USB 2.0/HDMI legacy systems without added series resistance.

FAQ
What is the maximum operating temperature range for D1213A-02SOL?
The D1213A-02SOL is rated for operation from –55°C to +125°C junction temperature. This range is validated per JEDEC JESD22-A104 and supported by thermal derating curves in the datasheet, ensuring reliable ESD protection in automotive under-hood and industrial control environments.
Does D1213A-02SOL require external biasing or control signals?
No. The D1213A-02SOL is a passive, unidirectional/bidirectional TVS array with no external control pins or bias requirements. It operates solely based on voltage thresholds-conducting only during transient overvoltage events above its breakdown voltage (6.0–9.0 V) and returning to high-impedance state afterward.
Can D1213A-02SOL protect both positive and negative ESD transients on the same line?
Yes. Each channel is bidirectional, meaning it clamps both positive and negative transients relative to GND. For example, Channel 1 (Pins 1–2) clamps +10.0 V during positive surges and –1.7 V during negative surges at 1 A, making it suitable for AC-coupled differential interfaces like USB and HDMI.
Is the SOT23-6 footprint compatible with automated optical inspection (AOI) and reflow processes?
Yes. The SOT23-6 package uses matte tin-plated Alloy 42 leads, solderable per MIL-STD-202 Method 208, and has been qualified for standard lead-free reflow profiles (J-STD-020 Level 1). Its defined pad layout (AP02001) ensures consistent solder joint formation and AOI detectability in high-volume manufacturing.
