Product details
Overview
D1213A-02S from Diodes Incorporated is a 2-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, and clamping voltages of 10.0 V (positive) and –1.7 V (negative) at 1 A, deployed in USB 2.0, HDMI, and SATA interfaces.
For engineers reviewing the D1213A-02S datasheet, D1213A-02S pinout, D1213A-02S application, or D1213A-02S equivalent, key selection criteria include channel capacitance ≤1.2 pF, bidirectional clamping performance under 8/20 µs transients, SOT353 package compatibility with high-density PCB layouts, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This dual-channel TVS array uses back-to-back diode configurations between VP and VN rails to provide symmetrical bidirectional transient suppression. Each channel integrates a top diode (CHx to VP) and bottom diode (VN to CHx), enabling rail-to-rail clamping without external biasing.
It operates over –65°C to +150°C, supports supply voltages from 3.3 V to 5.5 V, and maintains leakage current ≤1.0 µA at 5 V while delivering 5 A peak pulse current per channel under 8/20 µs waveform conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | ±15 kV air, ±8 kV contact - meets industrial and automotive ESD immunity requirements without additional circuitry |
| Channel Capacitance | 0.85 pF typ @ 1 MHz - preserves signal integrity on USB 2.0 (480 Mbps) and HDMI 1.4 differential pairs |
| Clamping Voltage (VCL1) | 10.0 V max @ 1 A, 8/20 µs - limits positive transients below 12 V logic rail tolerance |
| Clamping Voltage (VCL2) | –1.7 V max @ –1 A, 8/20 µs - prevents negative overshoot beyond –2 V, protecting CMOS input stages |
| Reverse Breakdown (VBR) | 6.0 V min @ 1 mA - ensures reliable turn-on before damage threshold of protected ICs |
| Dynamic Resistance | 0.9 Ω typ @ 1 A - enables fast voltage stabilization during sub-nanosecond ESD events |

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 | 0.35 pF typical capacitance; lower clamping (8.5 V / –1.5 V); SOT-23-6 package | Better suited for >5 Gbps interfaces (e.g., PCIe Gen3); requires larger board area | Select when ultra-low capacitance is critical and layout allows SOT-23-6 footprint |
| ESD5Z3.3T5G | Single-channel, 3.3 V standoff; 0.6 pF capacitance; SOD-523 package | Requires two devices per differential pair; no integrated VP/VN rails | Choose only for cost-sensitive, space-tolerant designs where discrete placement is acceptable |
Compared with SP1003-02HTG and ESD5Z3.3T5G, D1213A-02S uniquely balances 0.85 pF capacitance, integrated dual-rail referencing, and AEC-Q101 qualification in SOT353-making it optimal for space-constrained automotive and consumer high-speed interfaces requiring single-device integration.

FAQ
What is the maximum recommended trace length between D1213A-02S and the protected connector?
Trace length should be ≤3 mm from each CHx pin to its corresponding connector pad to minimize inductance-induced voltage overshoot during ESD events. Longer traces degrade clamping effectiveness-especially critical for ±15 kV air discharge where peak di/dt exceeds 10 A/ns. Layout must maintain tight coupling between CHx, VP, and VN routing to preserve common-mode rejection.
Does D1213A-02S require external decoupling capacitors on VP or VN pins?
No external decoupling is required on VP or VN for ESD suppression functionality. However, a 100 nF ceramic capacitor between VP and VN near the device improves high-frequency transient response by lowering impedance at the clamping node. This is recommended for systems with >100 MHz noise sources but not mandatory for basic IEC 61000-4-2 compliance.
Can D1213A-02S protect AC-coupled differential signals like HDMI or SATA?
Yes-its rail-referenced architecture functions correctly with AC-coupled lines because clamping occurs relative to VP and VN rails, not signal DC bias. For HDMI TMDS pairs, VP is tied to 3.3 V and VN to ground; the device clamps both positive and negative excursions regardless of common-mode voltage swing (typically 0.8–1.2 V), preserving signal fidelity.
How does thermal derating affect D1213A-02S's 5 A peak pulse rating?
The 5 A rating applies at 25°C ambient; above that, derating follows Figure 2 in DS35755-e.g., at 85°C ambient, peak pulse current drops to ~3.2 A (64% of rated value). This reflects junction temperature rise limiting safe energy absorption; designers must verify worst-case board temperature and adjust system-level surge margin accordingly.
