Product details
Overview
ESDAVLC8-1BT2Y from STMicroelectronics is an automotive-grade bidirectional single-line TVS diode for ESD protection of high-speed data lines, featuring 4.5 pF capacitance at 0 V, 8.5 V minimum breakdown voltage, and AEC-Q101 qualification. It delivers 17 kV IEC 61000-4-2 contact/air discharge immunity in a 0.6 mm² SOD882T package, ideal for CAN, LIN, USB, and automotive infotainment I/O ports.
For engineers reviewing the ESDAVLC8-1BT2Y datasheet, ESDAVLC8-1BT2Y pinout, ESDAVLC8-1BT2Y application, or ESDAVLC8-1BT2Y equivalent, key selection criteria include low-clamping-voltage response to 8/20 µs transients (≤24 V @ 1.3 A), sub-50 nA reverse leakage at 3 V, ISO 10605 compliance (15 kV air / 8 kV contact), and monolithic integration enabling PCB space savings without sacrificing surge robustness.
Technical Context
This device operates as a clamping-type transient suppressor with symmetrical bidirectional conduction-triggering at ≥8.5 V in either polarity and clamping ≤24 V during 8/20 µs surges up to 1.3 A. Its ultra-low 4.5 pF line capacitance preserves signal integrity on >100 Mbps interfaces without introducing measurable jitter or rise-time degradation.
Designed for automotive environments, it sustains operation from −50 °C to +125 °C junction temperature and meets MIL-STD-883G Class 3 HBM (≥25 kV) and ISO 7637-3 Pulse 3a/b immunity. The monolithic silicon structure eliminates bond-wire parasitics, ensuring repeatable clamping performance across thermal cycles and board-level reflow profiles.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDALC6V1-1BT2Y | Lower breakdown (6.1 V min), identical 4.5 pF capacitance and SOD882T package | Better suited for 3.3 V logic rails; less margin for 5 V tolerant interfaces | Select when protecting 3.3 V UART or SPI lines where lower trigger voltage reduces risk of false triggering |
| TPD2E001DRYR | Higher capacitance (11 pF), dual-line configuration, same 8.5 V breakdown, X2SON-4 package | Occupies larger PCB area (1.0 mm²), supports two independent lines instead of one | Choose when dual-line protection (e.g., USB D+/D−) is needed and 11 pF loading is acceptable for <480 Mbps data rates |
Compared with ESDALC6V1-1BT2Y and TPD2E001DRYR, the ESDAVLC8-1BT2Y provides optimal balance of high-voltage margin (8.5 V), minimal capacitance (4.5 pF), and smallest footprint (0.6 mm²), making it preferred for space-constrained, high-speed automotive data links requiring AEC-Q101 validation.

FAQ
What is the maximum peak pulse current the ESDAVLC8-1BT2Y can handle?
The ESDAVLC8-1BT2Y is rated for 1.3 A peak pulse current under 8/20 µs waveform conditions, as specified in Table 1 of the official ST datasheet (DocID025558 Rev 2). This value corresponds to its 30 W peak pulse power rating at 25 °C ambient, with derating applied above 25 °C per Figure 3.
Does this device require external biasing or control signals?
No. The ESDAVLC8-1BT2Y is a passive, bidirectional TVS diode that requires no external power, biasing, or control signals. It operates solely through avalanche breakdown triggered by overvoltage transients, with symmetrical conduction between I/O1 and I/O2 terminals.
Can it be used in non-automotive applications like consumer USB ports?
Yes. While AEC-Q101 qualified and optimized for automotive environments, its 4.5 pF capacitance, 17 kV ESD immunity, and 3.3–5 V system compatibility make it equally effective in consumer USB 2.0, HDMI, and audio jack protection-provided operating temperature remains within −50 °C to +125 °C limits.
How does its clamping voltage compare between I/O1→I/O2 and I/O2→I/O1 directions?
Clamping voltage differs slightly by direction: Figure 7 shows ≤24 V max for I/O1→I/O2, while Figure 8 specifies ≤22 V max for I/O2→I/O1 at 1.3 A. This asymmetry arises from internal doping profile and is fully characterized in the datasheet for accurate system-level worst-case analysis.
