Product details
Overview
VESD12C1-HD1HG3-08 from Vishay Semiconductors is a unidirectional ESD-protection diode in DFN1006-2A package, rated for 12 V reverse stand-off voltage, 4.4 A peak pulse current (8/20 μs), and 30 kV IEC 61000-4-2 contact discharge immunity - deployed on high-speed USB 2.0 data lines in automotive infotainment modules.
For engineers reviewing the VESD12C1-HD1HG3-08 datasheet, VESD12C1-HD1HG3-08 pinout, VESD12C1-HD1HG3-08 application, or VESD12C1-HD1HG3-08 equivalent, key selection criteria include clamping voltage at 4.4 A (20.5–22.7 V), dynamic resistance (0.4 Ω typ.), capacitance (26–40 pF at 0 V), and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This device implements a single-line, unidirectional TVS structure optimized for low-capacitance signal-line protection. Its silicon avalanche junction delivers precise 12 V reverse stand-off with tight 14.3–15.8 V breakdown tolerance at 1 mA, enabling robust overvoltage margin above system rail while minimizing false triggering.
The DFN1006-2A footprint supports high-density PCB layouts with < 0.5 mm height and MSL level 1 soldering compatibility. Cathode-marked pin configuration ensures correct polarity placement during automated assembly, critical for protecting bidirectional interfaces like USB where ground-referenced transient suppression must avoid forward conduction during normal operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 12 V - maximum continuous working voltage before leakage exceeds 0.1 μA; sets upper limit for protected line's DC operating range. |
| Reverse Clamping Voltage | 20.5–22.7 V at 4.4 A (8/20 μs) - peak voltage seen by downstream IC during ESD event; must stay below IC's absolute max input rating. |
| Capacitance | 26–40 pF at 0 V, 1 MHz - directly impacts signal integrity on high-speed lines (e.g., USB 2.0 eye diagram margin). |
| Dynamic Resistance | 0.4 Ω typical (TLP, 100 ns) - determines voltage overshoot during fast transients; lower value improves clamping response. |
| ESD Immunity | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - meets automotive and industrial ESD compliance requirements without external filtering. |
| Package | DFN1006-2A (1.0 × 0.6 × 0.4 mm) - enables 0201-compatible layout with cathode marking for automated optical inspection (AOI). |
| AEC-Q101 Qualified | Yes - validated for automotive underhood and cabin applications per stress test requirements including temperature cycling and HTRB. |
Pinout & Package
DFN1006-2A package: 1.0 mm × 0.6 mm body, 0.4 mm max height, single-row 2-terminal configuration with cathode marked by bar on top surface. Compatible with standard 0201 reflow profiles (peak 260 °C, MSL level 1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | Input side of protected line | Connected to signal source (e.g., USB PHY output); carries normal signal and diverts ESD current toward ground path. |
| Pin 2 (Cathode) | Ground reference terminal | Connected to system ground plane; provides low-inductance return path for transient current; marked with bar for orientation verification. |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile DFN1006-2A | 0.4 mm max height enables use in ultra-thin portable and automotive display modules where Z-axis space is constrained. |
| 12 V working voltage | Matches common 12 V automotive supply rails and USB 2.0 VBUS-tolerant I/O domains without requiring derating. |
| 30 kV ESD immunity | Exceeds IEC 61000-4-2 Level 4 requirement, eliminating need for secondary protection stages in cost-sensitive designs. |
| 26–40 pF capacitance | Preserves USB 2.0 signal rise/fall times (< 2 ns) and maintains > 400 MHz bandwidth for full-speed data integrity. |
| AEC-Q101 qualification | Validated for -55 °C to +150 °C junction operation, supporting deployment in engine control units and ADAS camera links. |
Applications
| USB 2.0 Data Lines | Automotive Infotainment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD-protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ12A | DO-214AC package (4.5 × 2.7 mm), 12 V stand-off, 29.2 V clamping at 12.3 A, 350 pF capacitance | Higher clamping voltage and capacitance; suited for power-rail or low-speed signal protection only | Select when board space allows larger package and signal speed < 10 Mbps; not suitable for USB 2.0. |
| TPD2E001DRYR | 2-channel, 5.5 V stand-off, 12 V clamping at 1 A, 12 pF capacitance, same DFN1006-2 package | Lower voltage rating and dual-channel configuration; requires redesign for single-line use | Choose for multi-line protection with tighter capacitance budget; verify 5.5 V VRWM compatibility with 12 V system rails. |
Compared with SMAJ12A and TPD2E001DRYR, VESD12C1-HD1HG3-08 uniquely balances 12 V working voltage, sub-40 pF capacitance, and automotive qualification in a 1.0 × 0.6 mm footprint - making it optimal for space-constrained, high-speed, automotive-grade ESD protection where both voltage margin and signal fidelity are critical.
