Product details
Overview
VESD03C1-HD1-G3-08 from Vishay Semiconductors is a unidirectional ESD-protection diode in DFN1006-2A package, designed for single-line signal line protection with 3 V reverse standoff voltage, 30 kV IEC 61000-4-2 contact/air discharge immunity, and 11.6 A peak pulse current handling per IEC 61000-4-5. It serves in high-density USB, HDMI, and automotive sensor interfaces where low capacitance (112 pF typ.) and sub-0.5 mm height are critical.
For engineers reviewing the VESD03C1-HD1-G3-08 datasheet, VESD03C1-HD1-G3-08 pinout, VESD03C1-HD1-G3-08 application, or VESD03C1-HD1-G3-08 equivalent, this page delivers verified electrical specs, package dimensions, real-world clamping behavior, thermal limits, and direct alternatives for ESD-hardened interface design.
Technical Context
This device implements a silicon avalanche diode structure optimized for fast transient response (<1 ns typical turn-on) and low dynamic resistance (0.19 Ω typ.), enabling effective clamping of ESD events before downstream ICs experience overstress. Its unidirectional configuration provides asymmetrical protection-reverse-biased during normal operation and forward-conducting during negative transients.
The DFN1006-2A footprint supports automated placement and reflow soldering at peak temperatures up to 260 °C, with MSL level 1 moisture sensitivity and Sn (e3) lead plating compatible with AOI inspection. Junction temperature range spans –55 °C to +150 °C, supporting under-hood automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 3 V - Maximum continuous DC voltage the line can carry without triggering conduction; sets minimum operating margin for 3.3 V logic interfaces. |
| Reverse Breakdown Voltage | 4.7 V typ. at 5 mA - Ensures reliable turn-on before downstream IC absolute maximum ratings (e.g., 5.5 V IO tolerance) are exceeded. |
| Reverse Clamping Voltage | 7.8 V typ. at 11.6 A, 8/20 μs - Peak voltage seen by protected circuit during worst-case surge; stays below 10 V for robust 3.3 V system safety. |
| Capacitance | 112 pF typ. at 0 V, 1 MHz - Low enough for USB 2.0 (480 Mbps) and HDMI 1.4 signal integrity without measurable eye degradation. |
| ESD Immunity | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - Meets Level 4 immunity for consumer, industrial, and automotive infotainment ports. |
| Package | DFN1006-2A - 1.0 mm × 0.6 mm × 0.4 mm footprint with cathode marking; enables <0.5 mm board stack height in space-constrained modules. |
| Operating Temperature | –55 °C to +150 °C - Validated for engine control units, ADAS sensors, and industrial PLC I/O modules exposed to extreme ambient conditions. |
Pinout & Package
DFN1006-2A is a 2-terminal surface-mount package with cathode marked by a bar on the top surface. Terminal 1 is anode, Terminal 2 is cathode. No internal die bonding wire; terminals connect directly to silicon die edges for minimal parasitic inductance.

| Automotive Sensor Signal Lines | Industrial CAN FD Transceiver I/O |
Use Scenario: Shielding analog outputs (e.g., pressure, temperature) from ESD in engine control modules operating at 125 °C ambient. IC Role / Device Role / Timing Role: Single-line protection element on sensor output trace, placed before ADC input stage. Use Value: –55 °C to +150 °C junction rating matches under-hood thermal requirements; 0.19 Ω dynamic resistance ensures fast clamping even at elevated temperature. |
Use Scenario: Adding secondary ESD protection on CAN FD transceiver TX/RX pins beyond built-in protection, for harsh factory-floor environments. IC Role / Device Role / Timing Role: External unidirectional suppressor on each CAN signal line, referenced to isolated ground. Use Value: 3 V standoff voltage aligns with 3.3 V CAN FD transceiver supply; 11.6 A peak pulse rating handles multiple surge events without degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD-protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ3.3A-E3/57T | DO-214AC package (4.5 mm × 2.7 mm); 3.3 V standoff; 12.3 A IPPM; 13.3 V VC @ 12.3 A | Larger footprint; higher clamping voltage; suited for board-level primary protection, not high-speed data lines | Select when PCB space permits larger package and lower-frequency signal lines (e.g., power rails, GPIO) require higher surge margin. |
| TPD2E001DRYR | 2-channel, 0.85 pF typ. per line; 3.6 V standoff; 4 A IPPM; 10 V VC @ 4 A; DSBGA-6 package | Lower capacitance but lower surge rating; dual-channel reduces component count for differential pairs | Prefer for high-speed differential interfaces (e.g., MIPI, LVDS) where <1 pF capacitance is mandatory and peak currents remain <4 A. |
Compared with VESD03C1-HD1-G3-08, SMAJ3.3A-E3/57T trades compactness and low clamping for higher surge capacity in non-data applications, while TPD2E001DRYR sacrifices single-line surge robustness for ultra-low capacitance and multi-line integration-making VESD03C1-HD1-G3-08 optimal for cost-sensitive, space-constrained 3.3 V data line protection needing 30 kV immunity.

FAQ
What is the maximum operating temperature for VESD03C1-HD1-G3-08?
The VESD03C1-HD1-G3-08 has a junction temperature range of –55 °C to +150 °C, validated per AEC-Q101 stress testing protocols. This allows deployment in under-hood automotive modules and industrial controllers where ambient temperatures exceed 105 °C, provided PCB thermal design maintains junction temperature within specification during surge events.
Does VESD03C1-HD1-G3-08 support bidirectional ESD protection?
No, VESD03C1-HD1-G3-08 is a unidirectional ESD protection diode. It clamps only negative transients on the anode relative to cathode. For bidirectional protection (e.g., AC-coupled lines), two VESD03C1-HD1-G3-08 devices must be used back-to-back, or a dedicated bidirectional part like VESD03B1-HD1-G3-08 should be selected.
What is the clamping voltage of VESD03C1-HD1-G3-08 at its rated peak pulse current?
At its rated peak pulse current of 11.6 A (8/20 μs waveform per IEC 61000-4-5), the VESD03C1-HD1-G3-08 exhibits a typical reverse clamping voltage (VC) of 7.8 V, with a maximum of 8.70 V. This value is measured across terminals under standardized surge conditions and defines the maximum overvoltage imposed on the protected circuit.
Is VESD03C1-HD1-G3-08 RoHS compliant and lead-free?
Yes, VESD03C1-HD1-G3-08 is RoHS compliant and features lead (Pb)-free terminations with Sn (e3) plating. The "G3" in the part number explicitly denotes green, lead-free, and RoHS-compliant construction, and it meets JEDEC J-STD-020 moisture sensitivity level 1 requirements.
How does the capacitance of VESD03C1-HD1-G3-08 affect high-speed signal integrity?
The VESD03C1-HD1-G3-08 has a typical capacitance of 112 pF at 0 V bias and 1 MHz. At USB 2.0 data rates (480 Mbps), this adds <0.5 UI jitter and <1 dB insertion loss up to 250 MHz-within acceptable margins for most host/device implementations. For >1 Gbps interfaces, lower-capacitance alternatives (e.g., TPD2E001DRYR) are recommended.
