Product details
Overview
D1213A-04TS from Diodes Incorporated is a 4-channel low-capacitance TVS diode array designed for ESD protection of high-speed data lines. It delivers ±15 kV air/±8 kV contact ESD immunity per IEC 61000-4-2, features 0.85 pF typical channel capacitance, 6.0 V reverse breakdown voltage, and operates across –65°C to +150°C - deployed in USB 2.0, HDMI, and Serial ATA interfaces.
For engineers reviewing the D1213A-04TS datasheet, D1213A-04TS pinout, D1213A-04TS application, or D1213A-04TS equivalent, key selection criteria include channel count, clamping voltage under 1 A (10.0 V positive / –1.7 V negative), dynamic resistance (0.9 Ω), leakage current (<1.0 µA at 5 V), and TSOT26 package compatibility with high-density PCB layouts.
Technical Context
This device implements a dual-rail TVS architecture with independent top (VP–channel) and bottom (channel–VN) silicon avalanche diodes per channel, enabling bidirectional transient suppression while maintaining signal integrity on differential or single-ended high-speed buses. Its low 0.85 pF input capacitance minimizes signal distortion at frequencies up to 1 GHz.
The TSOT26 package supports thermal dissipation of 300 mW at 25°C ambient, with RθJA = 417°C/W on standard FR-4 layout, and meets AEC-Q101 for automotive-grade reliability. Clamping occurs at 10.0 V (positive) and –1.7 V (negative) under 1 A 8/20 µs pulses, ensuring safe interface IC voltage rail excursions remain within tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | Air ±15 kV, Contact ±8 kV - qualifies for industrial and automotive port-level ESD compliance without external shielding. |
| Channel Input Capacitance | 0.85 pF typical - preserves signal rise/fall times & eye diagram integrity on USB 2.0 (480 Mbps) and HDMI 1.4 links. |
| Reverse Breakdown Voltage (VBR) | 6.0 V min at 1 mA - sets precise trigger threshold above 3.3 V/5 V supply rails, avoiding false triggering. |
| Clamping Voltage (VCL1/VCL2) | +10.0 V / –1.7 V at IPP = 1 A - limits transient overvoltage to levels safe for 3.3 V logic I/O and analog front-ends. |
| Leakage Current (IR) | 0.1–1.0 µA at VP = 5 V - negligible DC loading on high-impedance receiver inputs and precision reference paths. |
| Dynamic Resistance (RDYN) | 0.9 Ω typical - ensures fast energy shunting with minimal voltage overshoot during sub-nanosecond ESD events. |

IC Role / Device Role / Timing Role: Low-capacitance shunt protector on each differential TMDS pair, referenced to 3.3 V rail and chassis ground. Use Value: Sustains 1080p60 signal integrity with >3.5 dB margin in eye height and width per HDMI compliance test plan. |
| SATA III Transmitter Protection | Automotive Camera Link (FPD-Link III) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1006-04UTG | Higher 1.2 pF typical capacitance; 12 V VBR; 12.5 V clamping at 1 A. | Better suited for 12 V industrial I/O; less optimal for sub-1 GHz high-speed interfaces. | Select when higher VBR tolerance is needed for 5 V tolerant receivers with wider voltage margins. |
| TPD4E001DPYR | 0.5 pF typical capacitance; 5.5 V VBR; 8.5 V clamping; 30 kV air ESD rating. | Targeted at ultra-high-speed USB 3.0/PCIe Gen2; requires tighter layout control due to smaller 1.0 mm × 1.0 mm X2SON package. | Prefer for next-gen interfaces where <0.6 pF is mandatory and board space allows fine-pitch routing. |
Compared with SP1006-04UTG and TPD4E001DPYR, D1213A-04TS balances low capacitance (0.85 pF), robust 6 V VBR, and proven USB/HDMI interoperability in production designs - making it optimal for cost-sensitive, high-volume 480 Mbps–3 Gbps applications where AEC-Q101 is required but sub-0.6 pF is not.

FAQ
What is the maximum peak pulse current rating per channel?
The D1213A-04TS is rated for 5 A peak pulse current (8/20 µs waveform) per channel, verified per Figure 3 in DS35601 Rev. 6–2. This rating applies individually to each of the four channels when VP and VN are properly decoupled and layout follows AP02001 pad recommendations.
Can D1213A-04TS be used on 1.8 V logic interfaces?
No - its 6.0 V minimum reverse breakdown voltage (VBR) and 10.0 V positive clamping voltage exceed safe operating limits for 1.8 V I/O. It is specified for 3.3 V and 5 V systems only; use D1213A-02TS (2-channel, 3.3 V optimized) or SP3203 for 1.8 V applications.
Is the TSOT26 package compatible with standard reflow profiles?
Yes - the TSOT26 package is qualified for lead-free reflow per JEDEC J-STD-020, with MSL Level 1 rating. Peak temperature must not exceed 260°C, and time above 217°C should be limited to 60–150 seconds, consistent with IPC/JEDEC J-STD-020D.1.
Does D1213A-04TS support bidirectional signal paths like USB differential pairs?
Yes - its dual-rail architecture (VP and VN terminals) enables true bidirectional clamping. Each channel conducts during both positive and negative transients relative to the local signal swing, preserving differential mode integrity without adding common-mode noise on USB D+/D– or HDMI TMDS pairs.
