Product details
Overview
ESDAVLC6V1-1BT2 from STMicroelectronics is a single-line, bidirectional Transil™ ESD protection diode in thin SOD882 package, with 6.1 V minimum breakdown voltage, 6 pF typical capacitance at 3 V, and 2.5 A peak pulse current capability. It protects high-speed serial interfaces including USB 2.0, display, and camera links against IEC 61000-4-2 level 4 ESD events (±15 kV air, ±8 kV contact).
For engineers reviewing the ESDAVLC6V1-1BT2 datasheet, ESDAVLC6V1-1BT2 pinout, ESDAVLC6V1-1BT2 application, or ESDAVLC6V1-1BT2 equivalent, key selection criteria include low capacitance for signal integrity, bidirectional clamping behavior, compact footprint (0.6 mm²), and compliance with MIL-STD-883G Class 3B HBM.
Technical Context
This device operates as a monolithic silicon avalanche diode optimized for transient suppression on high-bandwidth data lines. Its bidirectional clamping architecture ensures symmetrical response to positive and negative ESD transients without polarity dependency, while its low 6 pF junction capacitance minimizes signal distortion up to 3 GHz (–15 dB S21 attenuation at 3 GHz).
The thin SOD882 package enables placement directly adjacent to connector pins or IC I/O pads, reducing parasitic inductance. Thermal design leverages monolithic integration for stable clamping voltage across –40 °C to +125 °C operating range, with <100 nA reverse leakage at 3 V and 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage | 6.1 V min @ 1 mA - defines minimum trigger threshold before clamping activates |
| Junction Capacitance | 6 pF typ @ 3 V - preserves signal integrity on USB 2.0 (480 Mbps) and display interfaces |
| Peak Pulse Current | 2.5 A @ 8/20 µs - withstands IEC 61000-4-2 level 4 contact discharge (8 kV) |
| Clamping Voltage | 15 V max @ 2.5 A - limits downstream IC stress during full ESD event |
| Leakage Current | 100 nA max @ 3 V - avoids DC loading of high-impedance data lines |
| Operating Temp | –40 °C to +125 °C - supports industrial and automotive cabin-adjacent applications |
Pinout & Package
ESDAVLC6V1-1BT2 uses the thin SOD882 surface-mount package (1.0 × 0.6 × 0.4 mm), optimized for minimal PCB area (0.6 mm²) and low profile. Pin 1 is marked by an index dot or notch; orientation is defined solely by this mark, not product marking rotation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode/Cathode Junction Node | Bidirectional terminal - connects to protected line (e.g., USB D+); no polarity assignment required |
| Pin 2 | Anode/Cathode Junction Node | Complementary bidirectional terminal - completes ESD current path to ground via PCB layout |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Clamping | Enables single-device protection of AC-coupled or differential lines without polarity constraints |
| 6 pF Capacitance @ 3 V | Minimizes insertion loss and timing skew on 480 Mbps USB 2.0 and 1080p video interfaces |
| Monolithic Silicon Construction | Eliminates bond-wire inductance, ensuring sub-nanosecond response to ESD transients |
| 0.6 mm² Footprint | Allows placement within 2 mm of connector I/O, reducing loop inductance and improving clamping efficacy |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD9X5.0ST5G | Higher 12 pF capacitance; 5.0 V nominal breakdown; SOD-923 package (0.8 × 0.6 mm) | Less suitable for >200 MHz interfaces due to higher capacitance; larger footprint increases trace inductance | Select only if lower clamping voltage (12 V @ 1 A) outweighs bandwidth penalty |
| TPD2E001DRYR | 0.75 pF capacitance; dual-line configuration; 5.5 V breakdown; X2SON package (0.8 × 0.8 mm) | Optimized for ultra-high-speed USB 3.0/PCIe but lacks IEC 61000-4-2 level 4 contact rating (only level 3) | Prefer for 5 Gbps+ links where ESD threat is limited to ≤6 kV contact discharge |
Compared with ESD9X5.0ST5G and TPD2E001DRYR, ESDAVLC6V1-1BT2 uniquely balances 6 pF capacitance, ±15 kV air discharge immunity, and 0.6 mm² footprint-making it optimal for space-constrained USB 2.0 and MIPI applications requiring full IEC level 4 compliance.

FAQ
What is the maximum clamping voltage of ESDAVLC6V1-1BT2 under IEC 61000-4-2 level 4 conditions?
The device clamps to a maximum of 15 V at 2.5 A peak pulse current (8/20 µs waveform), which corresponds to the worst-case IEC 61000-4-2 level 4 contact discharge (8 kV). This value is verified per Figure 5 in the official datasheet and ensures safe operation for 3.3 V I/O rails.
Can ESDAVLC6V1-1BT2 be used on differential pairs like USB D+/D− without degrading signal integrity?
Yes - its 6 pF typical capacitance at 3 V and symmetrical bidirectional structure preserve common-mode rejection and minimize skew between D+ and D−. Measured S21 attenuation remains below –15 dB up to 3 GHz (Figure 8), confirming suitability for full-speed USB 2.0 (480 Mbps) eye diagram compliance.
How does the thin SOD882 package differ mechanically from standard SOD882?
The thin SOD882 (T2 suffix) has reduced height: 0.30–0.40 mm vs. 0.40–0.50 mm for standard SOD882 (M2 suffix), enabling tighter stacking clearance in slim-profile handhelds. Both share identical footprint (1.0 × 0.6 mm), pin pitch (0.65 mm), and thermal pad layout per Figures 24 and 22.
Is ESDAVLC6V1-1BT2 compliant with RoHS and REACH requirements?
Yes - it carries ST's ECOPACK®2 certification (lead-free, halogen-free, compliant with JEDEC J-STD-020 moisture sensitivity level 1). The epoxy meets UL94 V0 flammability rating, and full material declarations are available via ST's Product Change Notification system and authorized distributor portals.
