Product details
Overview
D1213A-01LPQ from Diodes Incorporated is a single-channel, low-capacitance TVS diode array designed for ESD protection of high-speed data lines in automotive and portable electronics. It features 3.3V reverse working voltage, 0.85pF typical capacitance, ±8kV contact/±15kV air ESD rating per IEC 61000-4-2, and AEC-Q101 qualification - deployed in USB 2.0, HDMI, and Serial ATA interfaces.
For engineers reviewing the D1213A-01LPQ datasheet, D1213A-01LPQ pinout, D1213A-01LPQ application, or D1213A-01LPQ equivalent, key selection criteria include clamping voltage under 10V at 1A, sub-1pF signal-line capacitance, DFN1006-2 footprint compatibility, and automotive-grade reliability for compact high-speed port protection.
Technical Context
This TVS array uses a monolithic silicon avalanche structure optimized for fast transient response and minimal parasitic capacitance. Its bidirectional clamping behavior provides symmetrical protection against both positive and negative ESD transients, with VCL1 = 10.0V (positive) and VCL2 = –1.7V (negative) at 1A peak pulse current.
The device operates within –55°C to +150°C and maintains <1.2pF capacitance up to 1.65V reverse bias at 1MHz. Its dynamic resistance of 0.9Ω supports rapid energy dissipation during 8/20μs surge events while preserving signal integrity on GHz-range serial links.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 3.3V - Maximum continuous reverse operating voltage before leakage exceeds 1μA; sets upper limit for safe interface voltage swing. |
| VBR (min) | 6.0V at 1mA - Breakdown threshold ensuring reliable conduction only during overvoltage events, not normal operation. |
| VCL1 / VCL2 | 10.0V / –1.7V at 1A - Clamping voltages defining maximum stress imposed on protected IC pins during ESD strike. |
| CT (typ) | 0.85pF at 1.65V, 1MHz - Low capacitance minimizes signal distortion and insertion loss on USB 2.0/HDMI differential pairs. |
| ESD Rating | ±8kV contact / ±15kV air per IEC 61000-4-2 - Meets automotive and industrial immunity requirements for handheld and infotainment systems. |
| Package | X1-DFN1006-2 - 1.08 × 0.68 mm footprint with 0.53mm max height; enables routing under fine-pitch connectors without stubs. |
| Thermal RθJA | 500°C/W - Requires minimal copper area for thermal management in space-constrained PCB layouts. |
Pinout & Package
Package: X1-DFN1006-2 - ultra-compact, leadless, dual-terminal surface-mount package with NiPdAu-plated terminals and UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |

IC Role / Device Role / Timing Role: Per-lane unidirectional TVS (anode grounded) on each data and clock line, minimizing common-mode noise injection. Use Value: –1.7V negative clamping prevents forward-bias damage to receiver inputs; 150°C max junction temperature supports under-dash mounting. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J3.3A-Q | DO-214AC package; 300pF capacitance; 12V clamping at 1A | Not suitable for >100Mbps interfaces due to excessive capacitance and slower response | Select only for low-speed power rail or GPIO protection where size and speed are secondary. |
| SP1003-01UTG | 0.3pF capacitance; 3.3V VRWM; ±12kV ESD rating; SOD-923 package | Lower ESD robustness and no AEC-Q101 qualification limits use to non-automotive portable designs | Prefer for ultra-high-speed USB 3.0 or MIPI D-PHY if automotive qualification is not required. |
Compared with SMA6J3.3A-Q and SP1003-01UTG, D1213A-01LPQ uniquely balances automotive qualification, sub-1pF capacitance, and 10V clamping - making it optimal for AEC-Q101-compliant high-speed serial interfaces where signal fidelity and reliability are co-constrained.

FAQ
What is the maximum recommended PCB trace length between D1213A-01LPQ and the protected IC?
Trace length should be ≤2mm from TVS pin to IC I/O pin and ≤3mm from TVS ground pin to solid ground plane via. Longer traces increase inductance, degrading clamping response and allowing voltage overshoot beyond VCL. The DFN1006-2 package enables direct placement at the connector, minimizing loop area.
Does D1213A-01LPQ require external series impedance for USB 2.0 compliance?
No external series resistor is needed. Its 0.85pF capacitance and low dynamic resistance (0.9Ω) maintain USB 2.0 eye diagram compliance without added termination. Layout best practice is to route protected lines differentially with 90Ω ±10% impedance and avoid stubs longer than 1mm.
Can D1213A-01LPQ be used in bidirectional signal paths like HDMI TMDS?
Yes - its symmetrical clamping (VCL1 = 10.0V, VCL2 = –1.7V) and low capacitance make it suitable for bidirectional AC-coupled differential signals. For HDMI, place one device per TMDS channel with cathode tied to ground and anode to signal line, respecting polarity per schematic.
Is moisture sensitivity level (MSL) information provided for D1213A-01LPQ?
Yes - it is rated MSL Level 1 per J-STD-020, meaning unlimited floor life at ≤30°C/60% RH. No bake preconditioning is required prior to reflow. The NiPdAu terminal finish ensures solderability per MIL-STD-202, Method 208 after standard storage.
