Product details
Overview
VESD33C1-HD1HG3-08 from Vishay Semiconductors is a unidirectional ESD-protection diode in DFN1006-2A package, rated for 33 V reverse standoff voltage, 15 kV IEC 61000-4-2 contact/air discharge immunity, and 1.6 A peak pulse current (8/20 μs), deployed on high-voltage data lines in automotive infotainment interfaces.
For engineers reviewing the VESD33C1-HD1HG3-08 datasheet, VESD33C1-HD1HG3-08 pinout, VESD33C1-HD1HG3-08 application, or VESD33C1-HD1HG3-08 equivalent, key selection criteria include clamping voltage at 1.6 A (≤62.5 V), ultra-low capacitance (12–18 pF @ 0 V), dynamic resistance (3.6 Ω), and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This device implements a single-line, unidirectional TVS structure optimized for high-voltage signal line protection. Its design centers on low-capacitance silicon avalanche diode architecture with cathode-anode polarity, enabling fast response to ESD transients while minimizing signal distortion on 33 V-rated buses.
It operates within -55 °C to +150 °C junction temperature range and complies with IEC 61000-4-2 (±15 kV contact/air) and IEC 61000-4-5 (100 W, 8/20 μs). The DFN1006-2A footprint supports automated optical inspection (AOI) via Sn (e3) lead plating and meets MSL level 1 reflow requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 33 V - Maximum continuous DC operating voltage before leakage exceeds 0.1 μA; defines upper limit of protected line voltage. |
| Reverse Breakdown Voltage | 37–41 V at 1 mA - Ensures reliable triggering during overvoltage events without premature conduction. |
| Clamping Voltage | ≤62.5 V at 1.6 A (8/20 μs) - Limits transient voltage seen by downstream ICs to safe levels during ESD strikes. |
| Capacitance | 12–18 pF at 0 V, 1 MHz - Minimizes signal integrity impact on high-speed or RF-sensitive 33 V interfaces (e.g., CAN FD, LIN). |
| Dynamic Resistance | 3.6 Ω - Governs voltage overshoot under fast transients; lower value improves clamping consistency. |
| ESD Immunity | ±15 kV contact & air (IEC 61000-4-2) - Meets automotive and industrial ESD robustness requirements for exposed connectors. |
| Peak Pulse Power | 100 W (8/20 μs) - Sustains short-duration surges without thermal failure; validated per IEC 61000-4-5. |
Pinout & Package
DFN1006-2A package: 1.0 mm × 0.6 mm × 0.4 mm max height, 2-terminal surface-mount device with cathode marking bar. Compatible with standard reflow profiles (peak ≤260 °C) and AOI inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | Input/Line side | Connected to protected signal line; conducts transient current toward ground when clamped. |
| Pin 2 (Cathode) | Ground reference | Connected to system ground plane; establishes reference for unidirectional clamping action. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 12–18 pF enables use on high-frequency 33 V buses without signal degradation or timing skew. |
| AEC-Q101 qualified option | Available in AEC-Q101-compliant variant (VESD33C1-HD1H) - certified for automotive under-hood and infotainment applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD-protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ33A-E3/57T | DO-214AC package (4.5 mm × 2.7 mm); higher capacitance (>100 pF); 33 V standoff; ±30 kV ESD rating. | Used in board-level surge protection, not high-speed signal lines; unsuitable for space-constrained or high-frequency designs. | Select only when PCB area is unconstrained and signal bandwidth <1 MHz. |
| TPD2E001DRYR | 2-channel, bidirectional, 5.5 V standoff; 12 pF; DSBGA package; no AEC-Q101 option; lower voltage rating. | Targeted at USB/low-voltage I/O; incompatible with 33 V operation; requires redesign for voltage scaling. | Not suitable as direct alternative; consider only for new low-voltage designs with multi-line protection needs. |
Compared with SMAJ33A-E3/57T and TPD2E001DRYR, VESD33C1-HD1HG3-08 uniquely delivers 33 V standoff, sub-20 pF capacitance, and DFN1006-2A footprint in a single-line unidirectional configuration-enabling compact, high-fidelity ESD protection on automotive and industrial 33 V signal paths without compromising layout or performance.

FAQ
What is the maximum clamping voltage of VESD33C1-HD1HG3-08 under ESD stress?
The VESD33C1-HD1HG3-08 clamps to ≤62.5 V at 1.6 A peak pulse current (8/20 μs waveform per IEC 61000-4-5). This value ensures downstream ICs on 33 V lines remain within safe operating limits during transient events. The typical clamping voltage is 56 V, measured under identical conditions. VESD33C1-HD1HG3-08 achieves this with a dynamic resistance of 3.6 Ω.
Is VESD33C1-HD1HG3-08 qualified for automotive applications?
VESD33C1-HD1HG3-08 itself is RoHS-compliant and lead-free with Sn (e3) termination, but its AEC-Q101 qualification applies only to the VESD33C1-HD1H variant (ordering code suffix "H"). The "HG3-08" suffix indicates green tape, 10k/reel packaging, and standard qualification. For automotive use, specify VESD33C1-HD1HG3-08 only if non-AEC-Q101 grade suffices; otherwise, select VESD33C1-HD1H.
What is the capacitance of VESD33C1-HD1HG3-08 and why does it matter?
VESD33C1-HD1HG3-08 exhibits 12–18 pF capacitance at 0 V and 1 MHz. This ultra-low value minimizes loading on high-speed or RF-sensitive 33 V signal lines-such as those in automotive infotainment displays or industrial sensor interfaces-preventing signal attenuation, timing skew, or resonance. It directly enables compatibility with protocols like CAN FD and LVDS without requiring compensation.
How does the DFN1006-2A package of VESD33C1-HD1HG3-08 affect PCB layout?
The DFN1006-2A package of VESD33C1-HD1HG3-08 measures just 1.0 mm × 0.6 mm × 0.4 mm max, enabling placement directly at connectors or IC pins with minimal trace inductance. Its 2-terminal layout simplifies routing, and the cathode bar marking supports automated optical inspection. Thermal performance is enhanced by direct copper exposure on the bottom thermal pad (per footprint recommendation S8-V-3906.04-059).
Can VESD33C1-HD1HG3-08 replace VESD26C1-HD1 in a 33 V circuit?
No-VESD26C1-HD1 has a 26 V standoff and is rated for only ±20 kV ESD immunity, whereas VESD33C1-HD1HG3-08 provides 33 V standoff and ±15 kV immunity. Substituting VESD26C1-HD1 in a 33 V system risks premature conduction and thermal runaway. VESD33C1-HD1HG3-08 is the correct choice for 33 V nominal lines; VESD26C1-HD1 is intended for 26 V applications only.
