Product details
Overview
ESDALC6V1-1M2 from STMicroelectronics is a unidirectional single-line transient voltage suppressor (TVS) diode designed for ESD protection of high-speed data lines. It delivers 30 kV IEC 61000-4-2 contact discharge immunity, 6.1 V minimum breakdown voltage, 22 pF capacitance at 0 V, <100 nA leakage at 3 V, and fits in 0.6 mm² PCB area - ideal for cellular handset I/O ports.
For engineers reviewing the ESDALC6V1-1M2 datasheet, ESDALC6V1-1M2 pinout, ESDALC6V1-1M2 application, or ESDALC6V1-1M2 equivalent, key selection criteria include low capacitance for signal integrity, compact SOD882 footprint for dense layouts, unidirectional clamping behavior, and validated IEC 61000-4-2 Level 4 compliance for consumer electronics design-in.
Technical Context
This TVS diode operates as a clamping device in series with I/O signal paths, activating above 6.1 V to shunt ESD transients to ground. Its unidirectional architecture provides forward conduction only on the anode-to-cathode path, enabling asymmetric protection for DC-biased interfaces like USB D+ or HDMI TMDS lines.
It achieves 22 pF junction capacitance at 0 V reverse bias - measured at 1 MHz with 30 mV RMS signal - ensuring minimal signal distortion up to ~2.7 GHz (–3 dB point per S21 data). Peak pulse power dissipation is rated at 50 W (8/20 µs waveform) with 6 A maximum peak current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 6.1 V min. - Ensures reliable turn-on before damage threshold of protected ICs (e.g., 5.5 V tolerant I/O) |
| Clamping Voltage (VCL) | 10 V max. @ 6 A - Limits voltage seen by downstream circuit during 8/20 µs surge |
| Junction Capacitance | 22 pF typ. @ 0 V - Enables use on 480 Mbps USB 2.0 or 1.5 Gbps HDMI signals without measurable eye degradation |
| Leakage Current | <100 nA @ 3 V - Prevents DC loading on low-power sensor or audio bias networks |
| ESD Withstand | >30 kV contact discharge (IEC 61000-4-2) - Meets industrial handheld equipment requirements without external shielding |
| Package | SOD882 - 0.6 mm² footprint with 0.65 mm pitch supports 0201-class layout density |
Pinout & Package
ESDALC6V1-1M2 uses the SOD882 surface-mount package: two-terminal, cathode-bar marked, lead-free, RoHS-compliant, UL94 V0 epoxy body. Dimensions: 0.60 × 1.00 mm (L × W), height 0.47 mm, pin pitch 0.65 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Cathode (Pin 2) | Ground reference | Connected to system ground plane; establishes clamping reference and provides low-inductance return path for ESD current |
Key Features
| Feature | Design Value |
|---|---|
| Low capacitance | 22 pF @ 0 V enables >2 GHz signal bandwidth preservation on high-speed serial links |
| High ESD robustness | 30 kV contact discharge rating eliminates need for secondary protection layers in cost-sensitive designs |
| Small footprint | 0.6 mm² PCB area reduces routing congestion in smartphone camera modules and USB-C port assemblies |
| Low leakage | <100 nA @ 3 V avoids battery drain in always-on sensor nodes and wearable BLE peripherals |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD9B5.0ST5G (ON Semi) | 5.0 V VBR, 15 pF capacitance, SOD-923 package (0.45 mm²) | Lower clamping voltage but higher leakage (1 µA @ 3 V); better for 3.3 V logic, less suitable for 5 V tolerant interfaces | Select when lower VBR is required and leakage tolerance >1 µA exists |
| TPD2E001DRYR (TI) | Bi-directional, 12 pF, 0.65 mm × 0.65 mm X2SON package, integrated 10 Ω series resistor | Supports AC-coupled lines (e.g., Ethernet PHY) but adds signal attenuation; not suitable for DC-biased interfaces without redesign | Choose for bidirectional protection needs or where series impedance improves ESD energy absorption |
Compared with ESD9B5.0ST5G and TPD2E001DRYR, ESDALC6V1-1M2 offers optimal balance of 6.1 V VBR for 5 V systems, ultra-low leakage, and proven 30 kV robustness - making it preferred for cost-sensitive, high-volume consumer I/O protection where unidirectional clamping suffices.

FAQ
What is the maximum operating temperature for ESDALC6V1-1M2?
The ESDALC6V1-1M2 has a specified operating junction temperature range of –40 °C to +125 °C. This allows reliable operation in smartphone internal environments and industrial HMI enclosures without thermal derating. The device remains functional up to its storage temperature limit of +150 °C, though sustained operation above 125 °C is not guaranteed.
Does ESDALC6V1-1M2 require a heatsink for 50 W pulse handling?
No heatsink is required. The 50 W peak pulse power rating applies to a single 8/20 µs transient event at 25 °C ambient, with junction temperature rising only momentarily. Thermal mass of the SOD882 package and PCB copper pour provide sufficient transient heat dissipation; continuous power handling is limited to <100 mW due to low steady-state thermal resistance.
Can ESDALC6V1-1M2 be used on bidirectional signal lines like I²C?
Yes, but only if the line is DC-biased - e.g., pulled up to 3.3 V or 5 V. As a unidirectional TVS, it clamps positive transients to ground and blocks negative excursions beyond ~0.7 V forward drop. For true AC-coupled or floating lines, a bidirectional alternative like TPD2E001DRYR is required.
How does the 22 pF capacitance affect USB 2.0 signal integrity?
At 22 pF, ESDALC6V1-1M2 introduces <0.5% rise-time degradation on 480 Mbps USB 2.0 signals (200 ps nominal), verified by S21 attenuation data showing –3 dB at 1.81 GHz. Layout best practices - short traces, ground stitching vias near pins - maintain eye diagram compliance per USB-IF test specifications.
