Product details
Overview
VESD33C1-02VHG3-08 from Vishay Semiconductors is a unidirectional ESD protection diode in SOD-523 package, rated for 33 V reverse standoff voltage, 15 kV IEC 61000-4-2 contact discharge immunity, and 1.6 A peak pulse current (8/20 μs), deployed on high-speed data lines in automotive infotainment interfaces.
For engineers reviewing the VESD33C1-02VHG3-08 datasheet, VESD33C1-02VHG3-08 pinout, VESD33C1-02VHG3-08 application, or VESD33C1-02VHG3-08 equivalent, key selection criteria include clamping voltage at 1.6 A (≤62.5 V), 12–18 pF capacitance at 0 V, dynamic resistance of 3.6 Ω, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This device implements a single-line, cathode-grounded unidirectional TVS structure optimized for low-capacitance transient suppression on 33 V rail systems. Its 3.6 Ω dynamic resistance and 56–62.5 V clamping voltage at 1.6 A ensure predictable voltage limiting during IEC 61000-4-5 surges.
The SOD-523 footprint supports high-density PCB layouts with <0.7 mm height, while Sn (e3) lead plating enables AOI-compatible solder joint inspection. It operates across –55 °C to +150 °C junction temperature range and meets MSL level 1 per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 33 V - maximum continuous DC operating voltage before leakage exceeds 0.1 μA |
| Reverse Breakdown Voltage | 35.5–39.3 V at 1 mA - defines onset of avalanche conduction under ESD stress |
| Clamping Voltage | 56–62.5 V at 1.6 A, 8/20 μs - limits downstream IC voltage during surge events |
| Capacitance | 12–18 pF at 0 V, 1 MHz - preserves signal integrity on USB 2.0, CAN FD, or LIN bus lines |
| ESD Immunity | ±15 kV contact / ±15 kV air per IEC 61000-4-2 - meets automotive interior ESD requirements |
| Peak Pulse Power | 100 W at 8/20 μs - sustains transient energy without thermal failure |
| Dynamic Resistance | 3.6 Ω - determines voltage rise slope under fast-rising transients (TLP, 100 ns) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ33A-E3/57T | DO-214AC package (4.5 × 2.7 mm), 33 V VRWM, 600 W PPP, 15.4 A IPPM, 150 pF CD | Higher clamping (70 V), larger footprint, unsuitable for high-speed data lines | Select when board space permits and capacitance >100 pF is acceptable (e.g., power rail protection) |
| TPD2E001DRYR | 2-channel bidirectional array in SOT-553, 5 V VRWM, 12 kV ESD, 12 pF/channel, 3.5 Ω rdyn | Limited to ≤5.5 V systems; not rated for 33 V standby or automotive load dump | Prefer for dual-line 3.3 V/5 V interfaces like HDMI or I²C where bidirectional protection is required |
Compared with SMAJ33A-E3/57T and TPD2E001DRYR, VESD33C1-02VHG3-08 uniquely balances 33 V standoff, 15 kV ESD rating, sub-20 pF capacitance, and SOD-523 size-making it the only qualified option for compact, high-voltage, high-speed automotive data line protection.

FAQ
What is the maximum operating temperature range for VESD33C1-02VHG3-08?
VESD33C1-02VHG3-08 supports a junction temperature range of –55 °C to +150 °C, validated per AEC-Q101 stress testing. This enables deployment in under-hood ECUs, powertrain control units, and other high-temperature automotive environments where thermal cycling and sustained heat exposure occur. The SOD-523 package's MSL level 1 rating further ensures robustness during reflow assembly.
Does VESD33C1-02VHG3-08 meet AEC-Q101 qualification?
Yes, VESD33C1-02VHG3-08 is AEC-Q101 qualified, as confirmed in Vishay's official documentation (Rev. 1.4, Jan 2021). This qualification covers stress tests including HTGB, AC/DC life test, temperature cycling, and ESD (HBM/MM), validating its suitability for automotive applications such as body electronics, infotainment, and ADAS subsystems.
What is the clamping voltage of VESD33C1-02VHG3-08 at its rated peak pulse current?
VESD33C1-02VHG3-08 delivers a reverse clamping voltage of 56–62.5 V at 1.6 A peak pulse current (8/20 μs waveform), per IEC 61000-4-5. This value ensures downstream 33 V-rated transceivers remain within safe operating voltage during surge events, with margin below typical absolute maximum ratings of CAN FD or LIN ICs.
Can VESD33C1-02VHG3-08 be used on bidirectional signal lines like USB D+ and D−?
VESD33C1-02VHG3-08 is unidirectional and must be placed with anode to signal and cathode to ground. For true bidirectional lines such as USB 2.0 D+/D−, two devices are required-one per line-or a dedicated bidirectional array (e.g., VESD5V0C1-02V) should be selected. Its 33 V VRWM is appropriate for USB VBUS-coupled noise but not for direct 5 V rail clamping.
What is the capacitance of VESD33C1-02VHG3-08 and why does it matter for high-speed interfaces?
VESD33C1-02VHG3-08 exhibits 12–18 pF capacitance at 0 V and 1 MHz. This low value minimizes signal distortion, timing skew, and insertion loss on high-speed differential buses like USB 2.0 (480 Mbps) and CAN FD (5 Mbps), ensuring compliance with eye diagram and jitter specifications without requiring layout compensation.
