Product details
Overview
ESDAULC6-1U2 from STMicroelectronics is a unidirectional single-line TVS diode for ESD protection of high-speed data lines, featuring 0.8 pF typical line capacitance, 6 V breakdown voltage (IR = 1 mA), ±15 kV air/±8 kV contact IEC 61000-4-2 compliance, and ST0201 (0201) SMD package occupying only 0.18 mm² PCB area - deployed in smartphone USB/MIPI interfaces.
For engineers reviewing the ESDAULC6-1U2 datasheet, ESDAULC6-1U2 pinout, ESDAULC6-1U2 application, or ESDAULC6-1U2 equivalent, key selection criteria include ultralow capacitance for signal integrity, compact 0201 footprint for space-constrained mobile designs, IEC-level 4 ESD clamping performance, and leakage current <100 nA at 3 V standoff.
Technical Context
The ESDAULC6-1U2 implements a silicon avalanche diode structure optimized for transient suppression on single-ended high-frequency I/O lines. Its unidirectional configuration provides low forward-voltage clamping during negative transients while maintaining sub-1 pF capacitance up to 3 GHz.
It operates with a 6 V minimum breakdown voltage and clamps to ≤13 V at 1 A (8/20 µs), delivering 18 W peak pulse power handling. Junction temperature range spans −40 °C to +150 °C, supporting operation in thermally demanding portable electronics environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 6 V min @ 1 mA - ensures reliable turn-on before damage to protected IC I/O pins |
| Line Capacitance (Cline) | 0.8 pF typ @ 0 V, 200–3000 MHz - preserves signal integrity in USB 2.0, MIPI D-PHY, and HDMI CEC lines |
| Clamping Voltage (VCL) | ≤13 V @ 1 A, 8/20 µs - limits stress on downstream transceivers during ±8 kV contact ESD events |
| Leakage Current (IRM) | ≤100 nA @ 3 V - avoids DC loading of battery-powered sensor or audio bias networks |
| ESD Rating | ±15 kV air / ±8 kV contact per IEC 61000-4-2 Level 4 - meets global end-equipment immunity requirements |
| Package Size | ST0201 (0201 metric) - 0.60 × 0.30 × 0.25 mm footprint enables placement adjacent to connector pads |
Pinout & Package
ESDAULC6-1U2 uses the ST0201 (0201 metric) two-terminal surface-mount package. Pin 1 is marked by a visible dot or chamfered corner on the top side; Pin 2 is the cathode terminal connected to ground in standard unidirectional placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | I/O Line Input | Connected directly to protected high-speed signal (e.g., USB D+, MIPI CLK+); carries full transient current during ESD event |
| Pin 2 (Cathode) | Ground Reference | Must be tied to low-inductance system ground plane via shortest possible trace to ensure effective clamping |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow capacitance | 0.8 pF typ - enables use on >480 Mbps USB 2.0 and 1.5 Gbps MIPI D-PHY without signal degradation |
| 0201 SMD compatibility | 0.18 mm² PCB area - saves space in ultra-thin smartphone bezel and foldable display flex circuits |
| IEC 61000-4-2 Level 4 certified | ±15 kV air / ±8 kV contact - satisfies EN 61000-4-2 for CE-marked consumer handhelds |
| RoHS & ECOPACK®2 compliant | Lead-free, halogen-free, UL94 V0 epoxy - supports global environmental compliance and reflow soldering |
Applications
| Smartphone Data Interface Protection | Tablet MIPI D-PHY Lane Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD1E05U06DPYR (TI) | 0.6 pF typ capacitance, 5.5 V VBR, same ST0201 package | Slightly lower clamping (12.5 V @ 1 A) but tighter VBR tolerance | Preferred when tighter voltage matching to 1.8 V/3.3 V rail is required |
| UMK105CG060KV-F (Taiyo Yuden) | 0.7 pF typ, 6.0 V VBR, 0201 multilayer ceramic varistor (MLCV) | Higher leakage (~500 nA), less robust under repeated ESD stress | Consider for cost-sensitive volume production where long-term reliability is secondary |
Compared with TPD1E05U06DPYR and UMK105CG060KV-F, ESDAULC6-1U2 offers superior thermal stability (150 °C max Tj), lower leakage, and proven field reliability in premium mobile platforms - making it optimal for mission-critical high-speed interface protection.

FAQ
What is the maximum operating temperature for ESDAULC6-1U2?
The ESDAULC6-1U2 has an operating junction temperature range of −40 °C to +150 °C, verified per Table 1 in the official datasheet. This rating supports deployment in thermally constrained spaces such as smartphone battery compartments and near RF power amplifiers where ambient PCB temperatures may exceed 85 °C.
Can ESDAULC6-1U2 be used on bidirectional data lines like I²C?
No - ESDAULC6-1U2 is unidirectional and intended only for single-ended, ground-referenced lines. For bidirectional buses such as I²C or UART, ST recommends the bidirectional ESDALY6-1U2 or ESDALC6-1U2, which provide symmetrical clamping and identical 0.8 pF capacitance.
Does ESDAULC6-1U2 require a dedicated ground plane connection?
Yes - effective clamping depends on a low-inductance path to system ground. The cathode (Pin 2) must connect to a solid ground plane using a thermal pad or direct copper pour; traces longer than 1 mm significantly degrade ESD performance per Figure 5–6 transient response waveforms.
Is the ST0201 package compatible with standard 0201 pick-and-place equipment?
Yes - ESDAULC6-1U2 conforms to JEDEC MO-254 for 0201 packages and is qualified for automated assembly using vision-guided placement systems. ST recommends ±0.05 mm placement tolerance and 3.5 N placement force, as specified in Section 4.3 of the datasheet, to avoid solder paste displacement or tombstoning.
