Product details
Overview
D1213A-02SOLQ from Diodes Incorporated is a 2-channel, low-capacitance TVS diode array designed for ESD protection of high-speed data lines. It features a 3.3V reverse working voltage (VRWM), ±8 kV contact / ±15 kV air IEC 61000-4-2 ESD rating, and 0.85 pF typical channel capacitance at 3.3 V, enabling use in USB 2.0 and HDMI interfaces without signal integrity degradation.
For engineers reviewing the D1213A-02SOLQ datasheet, D1213A-02SOLQ pinout, D1213A-02SOLQ application, or D1213A-02SOLQ equivalent, key selection criteria include clamping voltage under 10 V at 1 A, automotive AEC-Q101 qualification, SOT23 package compatibility, and sub-1 pF input capacitance for high-speed serial links.
Technical Context
This dual-channel TVS array uses bidirectional avalanche diodes per channel referenced to GND, delivering symmetrical clamping for both positive and negative transients. Its low dynamic resistance (0.9 Ω) and fast response time (<1 ns) ensure effective suppression of ESD pulses while minimizing voltage overshoot on protected lines.
The device operates within –55°C to +150°C and is rated for 5 A peak pulse current (8/20 µs). Its 300 mW power dissipation and 417 °C/W junction-to-ambient thermal resistance are specified for FR-4 PCB mounting with Diodes' recommended SOT23 pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 3.3 V - Maximum continuous reverse operating voltage before leakage exceeds 1 nA; sets upper limit for signal swing in protected interface |
| VBR (min) | 6.0 V - Minimum breakdown voltage at 1 mA; ensures reliable conduction only during overvoltage events |
| VCL1 (typ) | 10.0 V - Clamping voltage for +1 A transient; defines worst-case voltage seen by downstream IC during ESD strike |
| CT (typ @ 3.3 V) | 0.85 pF - Channel-to-GND capacitance at DC bias; enables <1% signal attenuation in USB 2.0 (480 Mbps) applications |
| ESD Rating | ±8 kV contact / ±15 kV air - Complies with IEC 61000-4-2 Level 4; meets automotive infotainment system immunity requirements |
| AEC-Q101 | Qualified - Validated for automotive use including temperature cycling, HTRB, and ESD stress; supports PPAP documentation |
Pinout & Package
Package: SOT23 - 3-pin surface-mount plastic package (2.4 mm × 1.3 mm × 1.0 mm), RoHS-compliant, halogen-free, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Channel 1 Anode | Input node for first protected line (e.g., USB D+); connects to signal trace prior to IC receiver |
| Pin 2 | GND | Common cathode reference for both channels; must be low-inductance connection to system ground plane |
| Pin 3 | Channel 2 Anode | Input node for second protected line (e.g., USB D–); electrically isolated from Pin 1 except through shared GND path |
Key Features

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 |
|---|---|---|---|
| SP1006-02UTG | Higher VRWM (5.0 V), higher CT (1.2 pF typ), same SOT23-3 package | Targeted at 5 V logic interfaces; less suitable for 3.3 V USB/HDMI due to tighter voltage margin | Select when protecting 5 V tolerant ports where higher clamping voltage is acceptable |
| ESD5Z3.3T5G | Single-channel, identical VRWM (3.3 V) and CT (0.85 pF), same AEC-Q101 rating | Requires two devices for dual-line protection; increases BOM count and PCB routing complexity | Choose only if design requires independent channel biasing or staggered placement |
Compared with SP1006-02UTG and ESD5Z3.3T5G, D1213A-02SOLQ uniquely delivers dual-channel 3.3 V protection in one SOT23 package with lowest capacitance and automotive qualification-reducing component count while meeting stringent infotainment ESD requirements.

FAQ
What is the maximum clamping voltage for D1213A-02SOLQ under a 1 A ESD pulse?
The typical reverse clamping voltage (VCL1) is 10.0 V for positive transients at IPP = 1 A (8/20 µs waveform), measured between any channel and GND. This value ensures downstream receivers remain below absolute maximum ratings during IEC 61000-4-2 contact discharge events.
Is D1213A-02SOLQ compatible with automated SMT assembly processes?
Yes. The device uses matte tin-finished alloy 42 leadframe terminals, rated for solderability per MIL-STD-202, Method 208. Its SOT23 package and moisture sensitivity level 1 allow standard reflow profiles without baking, supporting high-yield automotive PCB assembly.
Does D1213A-02SOLQ require external biasing or series impedance for USB 2.0 protection?
No. The device is a bidirectional TVS array with internal GND reference and requires no external components. Its 0.85 pF capacitance and 10 V clamping voltage are optimized for direct placement between connector and transceiver, eliminating need for series resistors or bias networks.
How does the AEC-Q101 qualification impact design validation for automotive use?
AEC-Q101 qualification confirms the device passed stress tests including temperature cycling, high-temperature reverse bias, and ESD robustness-enabling direct integration into PPAP submissions. No additional qualification testing is required for infotainment applications operating from –40°C to +125°C junction temperature.
