Product details
Overview
VESD03C1-HD1HG3-08 from Vishay Semiconductors is a unidirectional ESD-protection diode in DFN1006-2A package, rated for 3 V reverse stand-off voltage, 30 kV IEC 61000-4-2 contact/air discharge immunity, and 11.6 A peak pulse current (8/20 μs), deployed on high-speed data lines in automotive infotainment interfaces.
For engineers reviewing the VESD03C1-HD1HG3-08 datasheet, VESD03C1-HD1HG3-08 pinout, VESD03C1-HD1HG3-08 application, or VESD03C1-HD1HG3-08 equivalent, key selection criteria include clamping voltage at 11.6 A (≤8.7 V), capacitance at 0 V (112 pF typ.), dynamic resistance (0.19 Ω), and AEC-Q101 qualification status for automotive use.
Technical Context
This device implements a single-line, unidirectional TVS structure optimized for low-capacitance transient suppression on signal paths. Its silicon design targets fast response to sub-nanosecond ESD events while maintaining low leakage (<80 μA at 3 V) and stable clamping performance across -55 °C to +150 °C junction temperature.
The DFN1006-2A footprint enables placement directly at I/O connectors or high-speed interface IC pins. Cathode marking aligns with standard polarity conventions, and Sn (e3) termination supports automated optical inspection and lead-free reflow up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 3 V - Maximum continuous working voltage before leakage exceeds 80 μA; sets upper limit for protected line DC bias. |
| Reverse Clamping Voltage | ≤8.7 V at 11.6 A (8/20 μs) - Peak voltage seen by downstream circuit during worst-case surge; ensures logic-level compatibility. |
| Capacitance | 112 pF typical at 0 V, 1 MHz - Low enough for USB 2.0 and audio lines without signal integrity degradation. |
| ESD Immunity | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - Meets automotive and industrial system-level ESD test requirements. |
| Dynamic Resistance | 0.19 Ω - Enables rapid voltage clamping with minimal overshoot during fast transients. |
| Operating Temperature | -55 °C to +150 °C - Supports under-hood and powertrain applications requiring extended thermal range. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronics per stress test requirements including HTGB, HTRB, and TCT. |
Pinout & Package
DFN1006-2A package: 1.0 mm × 0.6 mm × 0.4 mm max height, cathode marked with bar on terminal 2. RoHS-compliant, Sn (e3) plating, MSL level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Connected to protected signal line; conducts during positive ESD transients relative to ground. |
| 2 | Cathode | Connected to system ground; provides low-impedance path for ESD current; marked with bar on top surface. |
Key Features
| Feature | Design Value |
|---|---|
| Compact DFN1006-2A footprint | Enables placement within 2 mm of I/O connector or IC pad without compromising PCB real estate on dense layouts. |
| Low profile (< 0.5 mm) | Permits use in ultra-thin modules and stacked-board assemblies where Z-height is constrained. |
| Unidirectional protection | Provides asymmetric clamping ideal for DC-biased signal lines such as UART, CAN, or analog sensor inputs. |
| 100 W peak pulse power | Handles multiple IEC 61000-4-5 surges without parametric shift or failure under defined test conditions. |
| Sn (e3) termination | Ensures solder joint reliability and compatibility with AOI systems during high-volume SMT assembly. |
Applications
| Automotive Infotainment Display Interface | USB 2.0 Data Line Protection |
|---|---|
Use Scenario: Protecting LVDS or FPD-Link III video data lanes between head unit and TFT display in vehicles. IC Role / Device Role / Timing Role: Unidirectional ESD clamp placed at display connector to shunt transients before reaching serializer/deserializer ICs. Use Value: Prevents latch-up or damage to display driver ICs during door-handle or cable-disconnect ESD events, maintaining visual system uptime. |
Use Scenario: Safeguarding D+ and D- lines of USB 2.0 ports in automotive telematics modules. IC Role / Device Role / Timing Role: Signal-line TVS diode mounted adjacent to USB receptacle to suppress contact discharge before reaching USB PHY. Use Value: Maintains <112 pF capacitance to preserve eye diagram integrity at 480 Mbps while meeting ISO 10605 and IEC 61000-4-2 compliance. |
| Industrial Sensor Signal Conditioning | Automotive LIN Bus Node Protection |
Use Scenario: Shielding analog output lines (e.g., 0–5 V or 4–20 mA) from ESD in factory-floor pressure/temperature sensors. IC Role / Device Role / Timing Role: Low-leakage (≤80 μA) unidirectional clamp on sensor output trace, referenced to local ground plane. Use Value: Preserves measurement accuracy by limiting clamping voltage to ≤8.7 V during 30 kV discharges, avoiding ADC saturation or op-amp rail-to-rail excursion. |
Use Scenario: Protecting LIN transceiver pins in body control modules exposed to service technician ESD during diagnostics. IC Role / Device Role / Timing Role: Single-line ESD suppressor tied between LIN bus line and chassis ground, leveraging 3 V VRWM to match LIN's 12 V nominal but low-swing signaling. Use Value: Ensures uninterrupted communication during roadside service by surviving repeated ±30 kV contact discharges without parameter drift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD-protection diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ3.0A | DO-214AC package (4.5 mm × 2.7 mm), 3.3 V VBR, 100 W PPP, 150 pF capacitance | Higher capacitance and larger footprint; suited for board-level primary protection, not high-speed signal lines | Select when space allows and lower clamping speed is acceptable; avoid for USB or LVDS due to capacitance and size. |
| TPD2E001DRYR | 2-channel bidirectional array in DFN1006-6, 5 V VRWM, 10 pF capacitance, no AEC-Q101 rating | Lower capacitance but bidirectional; lacks automotive qualification and higher clamping voltage (12 V at 4 A) | Prefer for non-automotive USB or HDMI where dual-line protection and ultra-low capacitance are critical; not suitable for AEC-Q101 programs. |
Compared with SMAJ3.0A and TPD2E001DRYR, VESD03C1-HD1HG3-08 uniquely balances automotive qualification, compact DFN1006-2A size, 3 V stand-off, and 112 pF capacitance-making it optimal for space-constrained, safety-critical signal-line protection where unidirectional clamping and thermal robustness are required.

FAQ
What is the maximum operating temperature for VESD03C1-HD1HG3-08?
VESD03C1-HD1HG3-08 supports a junction temperature range of -55 °C to +150 °C, validated per AEC-Q101 stress testing. This enables deployment in under-hood automotive modules and industrial controllers where ambient temperatures exceed 105 °C, provided PCB thermal design maintains TJ within limits.
Is VESD03C1-HD1HG3-08 qualified to AEC-Q101?
Yes, VESD03C1-HD1HG3-08 is AEC-Q101 qualified. The "H" in the ordering code (VESD03C1-HD1HG3-08) explicitly denotes AEC-Q101 qualification per Vishay's documentation, covering tests including high-temperature reverse bias, temperature cycling, and ESD robustness.
What does the "G3-08" suffix indicate in VESD03C1-HD1HG3-08?
In VESD03C1-HD1HG3-08, "G" indicates RoHS-compliant + lead (Pb)-free terminations, "3" specifies tin (Sn, e3) plating, and "-08" denotes packaging in 10 k per 7″ reel with 8 mm tape width-standard for high-volume SMT assembly.
Can VESD03C1-HD1HG3-08 be used on bidirectional signal lines like I²C?
No-VESD03C1-HD1HG3-08 is unidirectional and designed for DC-biased lines. For bidirectional buses such as I²C, a bidirectional ESD diode (e.g., VESD03B1-HD1HG3-08) with symmetric clamping is required; using this part would block one signal polarity.
What is the typical capacitance of VESD03C1-HD1HG3-08 at 0 V and 1 MHz?
The typical capacitance of VESD03C1-HD1HG3-08 is 112 pF at 0 V reverse bias and 1 MHz, with a min/max range of 89–135 pF. This value is measured per standard JESD22-A114 and remains stable across process variation, supporting USB 2.0 and audio signal integrity.
