Product details
Overview
D1213A-02SR from Diodes Incorporated is a 2-channel low-capacitance TVS diode array designed for ESD protection of high-speed data lines. It features ±15 kV air/±8 kV contact ESD immunity per IEC 61000-4-2, 0.85 pF typical channel capacitance, and clamping voltages of 10.0 V (positive) and –1.7 V (negative) at 1 A, making it suitable for USB 2.0, HDMI, and SATA interfaces.
For engineers reviewing the D1213A-02SR datasheet, D1213A-02SR pinout, D1213A-02SR application, or D1213A-02SR equivalent, this device delivers verified low-capacitance transient suppression with AEC-Q101 qualification, SOT143 packaging, and precise dual-rail clamping behavior critical for signal integrity in 3.3 V/5.5 V systems.
Technical Context
This dual-channel TVS array uses bidirectional clamping architecture with separate VP (positive rail) and VN (negative rail) terminals to provide symmetrical overvoltage protection across two independent signal paths. Each channel integrates stacked diodes between signal line and VP/VN rails, enabling low dynamic resistance (0.9 Ω) and fast response to ESD transients.
It operates within a –65 °C to +150 °C junction temperature range and supports DC supply voltages from –0.5 V to VP+0.5 V per channel. The device maintains leakage current ≤ ±1.0 µA at 5 V bias and achieves reverse breakdown at ≥6.0 V (IR = 1 mA), ensuring robust immunity without false triggering during normal operation.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel low-capacitance TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1003-02HTG | 0.3 pF lower typical capacitance (0.55 pF); higher VBR (7.0 V min); same SOT143 package | Better suited for >1 GHz applications (e.g., USB 3.0 SS); less margin for 3.3 V rail clamping | Select when signal bandwidth exceeds 1.5 GHz and supply rail headroom permits ≥7 V breakdown |
| ESD5Z3.3T5G | Single-channel, 0.65 pF, 3.3 V nominal clamping; SOD-523 package - not pin-compatible | Requires two devices per differential pair; smaller footprint but higher assembly cost | Choose only if board area is severely constrained and dual-channel integration is unnecessary |
Compared with SP1003-02HTG and ESD5Z3.3T5G, D1213A-02SR offers optimal balance of 0.85 pF capacitance, 6.0 V VBR, and integrated dual-channel topology in SOT143-making it preferred for cost-sensitive, production-ready USB 2.0/HDMI designs where layout simplicity and AEC-Q101 compliance are required.

FAQ
What is the maximum operating voltage range for D1213A-02SR?
The device supports DC operating supply voltage VP – VN up to 6.0 V, with individual channel voltage tolerance from (VN – 0.5 V) to (VP + 0.5 V). At 3.3 V supply, this allows safe operation with ±0.5 V transient margin; at 5.5 V supply, it accommodates typical rail tolerances while maintaining clamping integrity.
How does D1213A-02SR achieve low capacitance without sacrificing ESD robustness?
It uses optimized silicon geometry and low-dielectric-constant passivation layers to minimize parasitic capacitance per channel (0.85 pF typical), while maintaining low dynamic resistance (0.9 Ω) and 5 A peak pulse capability through controlled avalanche doping profiles and efficient thermal dissipation via the SOT143 copper leadframe.
Can D1213A-02SR be used on 1.8 V logic interfaces?
Yes - its reverse breakdown voltage is ≥6.0 V (at 1 mA), so it remains non-conductive under 1.8 V bias. However, clamping action begins near 6 V, meaning it does not protect against overvoltage below that threshold; for sub-3 V rail protection, a lower-VBR TVS like D1213A-01SR (3.3 V VBR) is recommended.
Is the SOT143 package of D1213A-02SR compatible with standard reflow profiles?
Yes - the device is qualified for moisture sensitivity level 1 per J-STD-020 and supports standard Pb-free reflow profiles (peak 260 °C, 10 s max above 217 °C). Its matte tin finish ensures reliable solderability per MIL-STD-202, Method 208, with no pre-bake required for dry storage conditions.
