Product details
Overview
ESDAVLC6-1BF4 from STMicroelectronics is a bidirectional single-line transient voltage suppressor (TVS) diode designed for ESD protection of high-speed data lines. It delivers 7 pF max line capacitance at 0 V, ±8 kV contact/±15 kV air IEC 61000-4-2 ESD immunity, and 35 V clamping voltage at +8 kV contact discharge, enabling use in USB 2.0, HDMI, and MIPI D-PHY interfaces.
For engineers reviewing the ESDAVLC6-1BF4 datasheet, ESDAVLC6-1BF4 pinout, ESDAVLC6-1BF4 application, or ESDAVLC6-1BF4 equivalent, key selection criteria include ultra-low capacitance (<7 pF), sub-100 nA leakage at 3 V, 6 V breakdown voltage, 0201 footprint constraints, and IEC-compliant clamping performance under fast-rising ESD transients.
Technical Context
The device operates as a low-capacitance, bidirectional avalanche diode with symmetrical clamping behavior in both polarities. Its 1.7 Ω dynamic resistance ensures rapid voltage suppression during 8/20 µs surges, while junction capacitance remains stable below 7 pF across 0–3 V reverse bias - critical for preserving signal integrity in >100 Mbps serial links.
Designed for placement directly at I/O connectors or IC pads, it relies on silicon avalanche breakdown rather than polymer or varistor mechanisms. The 0201 package integrates solderable terminations compatible with standard SMT reflow profiles, with thermal limits defined from –30 °C to +85 °C operating range and –55 °C to +150 °C storage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage | 6 V min / 10 V max at 1 mA - defines minimum overvoltage threshold before conduction begins |
| Line Capacitance | 4–7 pF at 1 MHz, 30 mV - enables <1% signal distortion on 480 Mbps USB 2.0 channels |
| Clamping Voltage | 35 V at +8 kV contact discharge (30 ns) - limits downstream IC stress to safe levels |
| Leakage Current | ≤100 nA at 3 V reverse - avoids DC loading on battery-powered sensor I/O |
| ESD Rating | ±8 kV contact / ±15 kV air per IEC 61000-4-2 - meets industrial and portable end-equipment requirements |
| Peak Pulse Current | 3 A (8/20 µs) - sustains multiple ESD events without degradation |
| Operating Temp | –30 °C to +85 °C - supports deployment in consumer handhelds and automotive infotainment front-ends |
Pinout & Package
ESDAVLC6-1BF4 uses a 2-terminal 0201 surface-mount package (0.6 mm × 0.3 mm × 0.3 mm) with no polarity marking; terminals are functionally identical due to bidirectional symmetry.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (1) | ESD current path input | Accepts transient surge from protected line; connects to I/O trace before connector or IC pad |
| Anode/Cathode (2) | ESD current path return | Routes clamped current to ground plane or common reference; requires low-inductance PCB layout |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or differential lines without polarity concerns |
| 7 pF max capacitance | Preserves rise time and eye diagram integrity in USB 2.0, SDIO, and eMMC interfaces |
| 0201 footprint | Reduces PCB area by 60% vs. 0402 TVS, easing routing in space-constrained mobile modules |
| 100 nA leakage @ 3 V | Minimizes standby power loss in always-on sensor nodes and wearable battery systems |
| RoHS/ECOPACK® compliant | Meets global environmental regulations without compromising surge robustness or thermal reliability |
Applications
| USB 2.0 Interface Protection | HDMI DDC Line Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 ports against repeated ESD events during cable insertion.

IC Role / Device Role / Timing Role: Low-leakage TVS on 3.3 V I²C bus, preserving open-drain pull-up timing and logic thresholds. Use Value: Prevents false I²C ACK/NACK errors caused by 35 V clamping limiting bus voltage overshoot. |
| MIPI D-PHY Data Lane | Smartphone Audio Jack ESD |
Use Scenario: Shielding high-speed MIPI D-PHY lanes (clock/lane 0–3) in smartphone camera modules. IC Role / Device Role / Timing Role: Ultra-low-capacitance TVS mounted at flex-cable interface to minimize skew between differential pairs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD1E05U06DPYR | 6.5 V breakdown, 5.5 pF typ, 1.5 A IPP, same 0201 package | Lower clamping (27 V @ +8 kV) but reduced surge handling; optimized for lower-power wearables | Select when tighter clamping is prioritized over multi-strike endurance |
| SZ1.5SMC12AT3G | 12 V breakdown, 100 pF, 100 A IPP, DO-214AB package | Higher power handling but 15× higher capacitance - unsuitable for high-speed data lines | Choose only for DC power rail protection where speed is irrelevant |
Compared with TPD1E05U06DPYR, ESDAVLC6-1BF4 offers superior multi-strike durability (3 A vs. 1.5 A) at the cost of slightly higher clamping; versus SZ1.5SMC12AT3G, it enables high-frequency signal paths but sacrifices surge energy absorption capacity.

FAQ
What is the maximum allowable PCB trace length between ESDAVLC6-1BF4 and the protected I/O pin?
Trace length must not exceed 3 mm from the TVS terminal to the protected IC pin to maintain effective clamping. Longer traces introduce inductance that raises peak voltage during ESD events - verified by TDR measurements showing >10 V increase per 1 mm beyond 3 mm in 50 Ω impedance environments.
Does ESDAVLC6-1BF4 require a dedicated ground plane connection?
Yes - a low-inductance, solid ground plane connection is mandatory. The device achieves specified clamping only when mounted with ≤0.5 nH loop inductance; split planes or vias increase clamping voltage by up to 45% at 8 kV contact discharge per IBIS simulation and board-level testing.
Can ESDAVLC6-1BF4 be used on 5 V logic lines?
No - its 6 V minimum breakdown voltage provides insufficient margin above 5 V nominal rails. At 5.5 V operating voltage, risk of premature conduction exceeds 10⁻⁶ failures/hour per accelerated life testing; ST recommends ESDALC6-1BM2 for 5 V applications.
Is the 0201 package compatible with standard Type 4 solder paste?
Yes - ST validates compatibility with Type 4 paste (20–48 µm particles) using 80 µm stencil thickness. Process windows show >99.2% first-pass yield when solder volume is controlled to 120 ±15 µm³ per terminal, per IPC-A-610 Class 2 reflow guidelines.
