Product details
Overview
VESD01C1-HD1-G3-08 from Vishay Semiconductors is a unidirectional single-line ESD-protection diode in DFN1006-2A package, rated for 1 V reverse stand-off voltage, 30 kV IEC 61000-4-2 contact/air discharge immunity, and 100 W peak pulse power, deployed on high-speed USB 2.0 data lines to suppress transient overvoltage.
For engineers reviewing the VESD01C1-HD1-G3-08 datasheet, VESD01C1-HD1-G3-08 pinout, VESD01C1-HD1-G3-08 application, or VESD01C1-HD1-G3-08 equivalent, key selection criteria include clamping voltage at 11 A (6.9 V max), dynamic resistance (0.13 Ω typ), capacitance (230 pF max), junction temperature range (–55 °C to +150 °C), and RoHS-compliant Sn (e3) terminations.
Technical Context
This device operates as a unidirectional TVS diode with cathode-anode polarity, leveraging silicon avalanche breakdown to clamp transients above its 2.55–2.85 V breakdown threshold. Its low 0.13 Ω dynamic resistance ensures minimal voltage overshoot during fast 8/20 μs surges.
Designed for placement directly at I/O connectors, it delivers ±30 kV ESD protection per IEC 61000-4-2 while maintaining signal integrity on 480 Mbps USB 2.0 channels via 230 pF max capacitance at 0 V bias and sub-1.2 V forward clamping at 11 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 1 V - Maximum continuous working voltage before leakage exceeds 100 μA; sets upper limit for DC-biased signal lines. |
| Reverse Breakdown Voltage | 2.55–2.85 V at 5 mA - Precise avalanche onset ensures predictable clamping initiation without premature conduction. |
| Reverse Clamping Voltage | 6.9 V max at 11 A, 8/20 μs - Limits voltage seen by protected IC to safe level during surge events. |
| Capacitance | 230 pF max at 0 V, 1 MHz - Low enough to avoid signal degradation on USB 2.0 differential pairs. |
| Peak Pulse Power | 100 W per IEC 61000-4-5 - Sustains high-energy 8/20 μs transients without thermal failure. |
| ESD Immunity | ±30 kV contact & air discharge per IEC 61000-4-2 - Meets automotive and industrial system-level ESD requirements. |
| Junction Temperature Range | –55 °C to +150 °C - Supports operation in under-hood automotive and industrial environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD-protection diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ1.0A | DO-214AC package (4.5 mm × 2.7 mm), 1.0 V VRWM, 600 W PPP, 300 pF capacitance | Higher capacitance and larger footprint unsuitable for USB 2.0; better for lower-speed industrial I/O | Select when board space allows larger package and higher surge energy handling is required. |
| TPD1E10B06DPYR | 0.6 mm × 0.3 mm DFN-2, 1.0 V VRWM, 30 kV ESD, 12 pF capacitance, 1.2 A IPPM | Lower clamping voltage (5.5 V) and much lower capacitance optimized for USB 3.0/HSIC | Prefer for next-gen high-speed interfaces where <15 pF is mandatory; not drop-in due to different surge rating. |
Compared with SMAJ1.0A and TPD1E10B06DPYR, VESD01C1-HD1-G3-08 uniquely balances ultra-small DFN1006-2A size, 30 kV ESD robustness, and USB 2.0-compatible 230 pF capacitance-making it optimal for cost-sensitive, space-constrained consumer and automotive infotainment designs.

FAQ
What is the maximum clamping voltage of VESD01C1-HD1-G3-08 under IEC 61000-4-5 surge conditions?
The VESD01C1-HD1-G3-08 exhibits a maximum reverse clamping voltage of 6.9 V at 11 A peak pulse current (8/20 μs waveform), as specified in its absolute maximum ratings table. This value ensures downstream ICs see limited overvoltage during surge events. The VESD01C1-HD1-G3-08 achieves this with a typical dynamic resistance of 0.13 Ω, minimizing voltage overshoot during fast transients.
Does VESD01C1-HD1-G3-08 meet automotive qualification standards?
VESD01C1-HD1-G3-08 is part of the AEC-Q101-qualified VESDxxC1-HD1 family; however, the specific variant VESD01C1-HD1-G3-08 carries the "G3" environmental code indicating RoHS-compliant, lead-free termination but no explicit AEC-Q101 suffix in its ordering code. For automotive use, confirm qualification status via Vishay's official part search using the base number VESD01C1-HD1.
What is the capacitance of VESD01C1-HD1-G3-08 and how does it affect USB 2.0 signal integrity?
The VESD01C1-HD1-G3-08 has a maximum capacitance of 230 pF at 0 V and 1 MHz, with typical value 192 pF. This is within acceptable limits for full-speed USB 2.0 (480 Mbps), where total channel capacitance must remain below ~300 pF to avoid eye diagram closure. The VESD01C1-HD1-G3-08 maintains signal fidelity without requiring additional equalization or layout compensation.
Can VESD01C1-HD1-G3-08 be used in bidirectional signal paths?
No - VESD01C1-HD1-G3-08 is a unidirectional ESD protection diode, configured with cathode-anode polarity. It protects only against positive transients on the cathode side relative to ground. For bidirectional protection (e.g., RS-485, CAN), a symmetric dual-diode array or dedicated bidirectional TVS like VESD05C1-HD1 must be selected instead of VESD01C1-HD1-G3-08.
What reflow profile is recommended for soldering VESD01C1-HD1-G3-08?
VESD01C1-HD1-G3-08 is rated MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C. Standard IPC/JEDEC J-STD-020-compliant lead-free reflow profiles apply, with no pre-baking required. Its Sn (e3) plating ensures compatibility with automated optical inspection (AOI) and reliable wetting on OSP- or ENIG-finished PCBs.
