Product details
Overview
D1213A-02WL from Diodes Incorporated is a 2-channel low-capacitance TVS diode array designed for ESD protection of high-speed data lines. It delivers ±8 kV contact / ±15 kV air IEC 61000-4-2 ESD immunity, 3.3 V reverse working voltage, 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-02WL datasheet, D1213A-02WL pinout, D1213A-02WL application, or D1213A-02WL equivalent, key selection criteria include clamping voltage under 10.0 V (positive transients), dynamic resistance of 0.9 Ω, and SOT323 package compatibility with high-density PCB layouts for signal integrity-critical ports.
Technical Context
This dual-channel unidirectional TVS array protects two independent signal lines referenced to GND. Each channel features a low-leakage silicon avalanche structure with 7.5 V typical breakdown voltage and 10.0 V max clamping at 1 A, optimized for fast transient suppression without signal distortion.
Its 0.85 pF typical capacitance at 1.65 V and 1.2 pF max ensure minimal loading on 480 Mbps USB 2.0 and 1.65 Gbps DVI/HDMI differential pairs. The device operates across –55°C to +125°C and meets full RoHS, halogen-free, and antimony-free "Green" compliance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | ±8 kV contact / ±15 kV air - validated protection level for end-equipment compliance testing |
| Reverse Working Voltage (VRWM) | 3.3 V - matches standard 3.3 V I/O rail voltage, preventing leakage during normal operation |
| Clamping Voltage (VCL1, +ve) | 10.0 V max at 1 A - limits transient overvoltage to safe levels for downstream 3.3 V logic |
| Channel Capacitance (CT) | 0.85 pF typ @ 1.65 V, 1 MHz - preserves signal integrity on USB 2.0 and HDMI data lanes |
| Breakdown Voltage (VBR) | 6.0–9.0 V @ 1 mA - ensures reliable triggering before IC damage thresholds are exceeded |
| Dynamic Resistance (RDYN) | 0.9 Ω typ - enables rapid energy shunting with minimal voltage overshoot during ESD events |
| Package | SOT323 - 3-pin surface-mount footprint with 0.65 mm lead pitch, compatible with automated assembly |
Pinout & Package
SOT323 package: 3-terminal plastic molded case, 2.10 mm × 1.30 mm × 0.90 mm body, matte tin-plated Alloy 42 leadframe, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Channel 1 Anode | Input node for first protected signal line; connects to data line (e.g., USB D+) |
| 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 signal line; connects to complementary data line (e.g., USB D−) |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel low-capacitance TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1003-02UTG | 0.5 pF typ capacitance, 5.5 V VRWM, ±12 kV contact ESD rating | Better suited for 1.8 V/2.5 V I/O rails; lower clamping but narrower voltage margin | Select when protecting lower-voltage high-speed interfaces like MIPI D-PHY where <0.6 pF is mandatory |
| ESD5Z3.3T5G | Single-channel, 0.65 pF typ, 3.3 V VRWM, ±12 kV contact rating | Requires two devices for dual-line protection; higher BOM count and layout area | Choose only if discrete placement flexibility or legacy single-channel design reuse is required |
Compared with SP1003-02UTG and ESD5Z3.3T5G, D1213A-02WL uniquely balances 3.3 V rail compatibility, dual-channel integration, and 0.85 pF capacitance-making it optimal for cost-sensitive, space-constrained USB 2.0 and HDMI designs requiring certified ±8 kV contact ESD performance.

FAQ
What is the maximum clamping voltage for D1213A-02WL under a 1 A ESD pulse?
The maximum clamping voltage for positive transients (VCL1) is 10.0 V at 1 A, 8/20 μs waveform, measured between any channel and GND. This value ensures downstream 3.3 V logic remains within safe operating limits during standardized IEC 61000-4-2 testing.
Can D1213A-02WL be used for bidirectional signal lines like RS-485?
No - D1213A-02WL is a unidirectional TVS array with anode-input configuration. It protects only positive-going transients on 3.3 V referenced lines. For true bidirectional protection (e.g., RS-485), a symmetric dual-rail TVS such as D24Z5.6LPSQ-7 is required.
Is the SOT323 package of D1213A-02WL compatible with reflow soldering per J-STD-020?
Yes - the device is rated Moisture Sensitivity Level 1 per J-STD-020 and supports standard Pb-free reflow profiles. Its matte tin finish on Alloy 42 leadframe ensures reliable wetting and joint formation without special pre-bake requirements.
Does D1213A-02WL meet automotive AEC-Q200 stress test requirements?
No - D1213A-02WL is not AEC-Q200 qualified. It is specified for commercial and industrial temperature ranges (–55°C to +125°C) but lacks the extended reliability testing (e.g., temperature cycling, board flex, failure rate analysis) required for automotive-grade qualification.
