Product details
Overview
ESDAVLC8-1BM2 from STMicroelectronics is a single-line, bidirectional transient voltage suppressor (TVS) diode designed for ESD protection of high-speed data lines. It features a minimum breakdown voltage of 8.5 V, 4.5 pF capacitance at 0 V, <50 nA reverse leakage at 3 V, and meets IEC 61000-4-2 Level 4 (±17 kV contact/air discharge) in compact SOD882 package. It is deployed in USB 2.0, HDMI, and cellular handset I/O ports where signal integrity and board space are critical.
For engineers reviewing the ESDAVLC8-1BM2 datasheet, ESDAVLC8-1BM2 pinout, ESDAVLC8-1BM2 application, or ESDAVLC8-1BM2 equivalent, key selection criteria include low-line capacitance (<5 pF), bidirectional clamping performance, IEC-compliant ESD robustness, and SOD882 footprint compatibility with high-density PCB layouts.
Technical Context
This TVS diode uses monolithic silicon avalanche structure to provide symmetrical clamping in both polarities without external biasing. Its low dynamic resistance (2 Ω typical at 1 A pulse) ensures rapid voltage suppression during sub-nanosecond ESD events while maintaining minimal signal distortion on protected lines.
Designed specifically for unidirectional line protection with no DC path, it operates across –55 °C to +150 °C junction temperature and delivers 30 W peak pulse power (8/20 µs waveform) with clamping voltage ≤17 V at 1.3 A peak current - enabling reliable protection of 3.3 V and 5 V interface circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 8.5 V min (direct), 14.5 V min (reverse); ensures triggering before damage to 3.3 V/5 V I/O structures |
| Junction Capacitance (CLINE) | 4.5 pF at 0 V; preserves signal rise time & bandwidth in >100 MHz interfaces like USB 2.0 |
| Peak Pulse Power (PPP) | 30 W (8/20 µs); sustains multiple ESD strikes without degradation in handheld device use cases |
| Clamping Voltage (VCL) | ≤17 V at 1.3 A IPP; limits transient overvoltage to safe levels for downstream logic inputs |
| Leakage Current (IRM) | <50 nA at 3 V; avoids loading of high-impedance analog or reference lines |
| ESD Rating | ±17 kV contact & air (IEC 61000-4-2 Level 4); exceeds industrial and consumer immunity requirements |
| Package | SOD882 (0.6 mm² footprint); enables placement adjacent to connectors without trace stubs |
Pinout & Package
The ESDAVLC8-1BM2 is housed in a 2-pin SOD882 surface-mount package with exposed pad not electrically connected. Pin 1 and Pin 2 serve as bidirectional I/O terminals with no polarity marking required for ESD protection function.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | I/O Line Terminal (Anode/Cathode) | Bidirectional connection point; symmetric avalanche structure allows either terminal to act as anode or cathode depending on transient polarity |
| Pin 2 | I/O Line Terminal (Cathode/Anode) | Second terminal of differential pair; forms low-inductance path to ground via PCB layout for effective ESD shunting |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Clamping | Enables single-device protection of AC-coupled or floating data lines without polarity constraints |
| Ultra-Low 4.5 pF Capacitance | Minimizes insertion loss and reflection in high-speed serial links up to 480 Mbps (USB 2.0) |
| Monolithic Silicon Construction | Eliminates bond wire inductance and inter-die mismatch, improving response time consistency |
| ECOPACK®2 Compliance | Meets RoHS and halogen-free requirements without compromising surge handling capability |
Applications
| USB 2.0 Data Lines | HDMI DDC/CEC Channels |
|---|---|
Use Scenario: Protecting differential USB 2.0 D+/D– lines from user-handling ESD in portable docking stations.

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 nominal breakdown; 15 pF capacitance; SOD-923 package | Higher capacitance limits use to lower-speed interfaces (<10 MHz) | Select when lower clamping voltage is prioritized over bandwidth preservation |
| TPD2E001DRYR (TI) | Dual-channel array; 10 pF per line; 0.65 mm × 0.65 mm DRY package | Offers dual-line protection in same footprint but higher capacitance per channel | Choose for space-constrained dual-line protection where 10 pF is acceptable |
Compared with ESD9B5.0ST5G and TPD2E001DRYR, the ESDAVLC8-1BM2 provides superior high-frequency performance due to its 4.5 pF capacitance and optimized monolithic structure, making it preferred for USB 2.0, HDMI, and other >100 MHz interfaces requiring minimal signal loading.

FAQ
What is the maximum operating temperature for ESDAVLC8-1BM2?
The ESDAVLC8-1BM2 has a specified operating junction temperature range of –55 °C to +150 °C, validated per MIL-STD-883G Class 3 testing. This allows deployment in automotive under-hood modules, industrial motor drives, and outdoor telecom equipment without thermal derating in most PCB layouts.
Does ESDAVLC8-1BM2 require external biasing for bidirectional operation?
No. The device uses a symmetric monolithic avalanche structure with identical forward and reverse breakdown characteristics. It functions bidirectionally without any external DC bias or polarity orientation-Pin 1 and Pin 2 are electrically interchangeable in circuit layout.
How does the 4.5 pF capacitance impact USB 2.0 signal integrity?
At 4.5 pF, the device introduces negligible impedance mismatch on 90 Ω differential USB 2.0 traces, preserving eye diagram opening and jitter margin. Measured S21 attenuation remains below –0.5 dB up to 500 MHz, confirming suitability for full-speed (480 Mbps) operation without equalization.
Can ESDAVLC8-1BM2 be used in place of ESDAVLC8-1BT2?
Yes, with mechanical qualification. Both share identical electrical specs and SOD882/SOD882T are footprint-compatible variants-the "M2" uses standard SOD882, while "T2" uses thinner SOD882T. Thermal and electrical performance are equivalent; only reflow profile and stencil design differ slightly due to package height variation.
