Product details
Overview
VESD33C1-HD1-G3-08 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 discharge immunity, and 1.6 A peak pulse current (8/20 μs), deployed in high-speed USB, HDMI, and automotive infotainment interfaces.
For engineers reviewing the VESD33C1-HD1-G3-08 datasheet, VESD33C1-HD1-G3-08 pinout, VESD33C1-HD1-G3-08 application, or VESD33C1-HD1-G3-08 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 low-capacitance signal-line protection. Its silicon design targets fast transient response (TLP-measured rdyn = 3.6 Ω) and stable clamping under IEC 61000-4-2 and -4-5 stress conditions.
The DFN1006-2A footprint enables placement on dense PCBs near connectors, with cathode-marked orientation and Sn (e3) termination compatible with standard reflow and AOI inspection. It operates across –55 °C to +150 °C junction temperature range and supports green RoHS-compliant assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 33 V - maximum continuous working voltage before conduction begins; defines upper limit for protected line operating voltage. |
| Reverse Breakdown Voltage | 37–41 V @ 1 mA - ensures reliable triggering above system rail; tight 4 V window minimizes overvoltage risk during ESD events. |
| Reverse Clamping Voltage | ≤62.5 V @ 1.6 A, 8/20 μs - limits transient voltage seen by downstream ICs; critical for safeguarding 3.3 V or 5 V interface receivers. |
| Capacitance | 12–18 pF @ 0 V, 1 MHz - preserves signal integrity on high-speed lines (e.g., USB 2.0, HDMI DDC) without measurable rise-time degradation. |
| ESD Immunity | ±15 kV contact / ±15 kV air per IEC 61000-4-2 - meets Level 4 industrial and automotive ESD robustness requirements. |
| Peak Pulse Power | 100 W @ 8/20 μs - sustains single-event surge energy without thermal runaway or parametric shift. |
| Dynamic Resistance | 3.6 Ω (TLP, 100 ns) - determines voltage overshoot during fast transients; lower value improves clamping precision. |
Pinout & Package
DFN1006-2A package: 1.0 mm × 0.6 mm × 0.4 mm max height, cathode marked on top surface, Sn (e3) matte tin terminations, MSL level 1, compatible with standard SMT reflow profiles (peak ≤260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Connected to protected signal line; forward-biased during positive transients to shunt current to ground. |
| Pin 2 | Cathode | Connected to system ground; provides low-impedance return path for ESD current; marked with bar on package top. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 12–18 pF enables use on >480 Mbps USB 2.0 and HDMI DDC/CEC lines without signal distortion. |
| AEC-Q101 qualified option | Available in AEC-Q101-qualified variant (VESD33C1-HD1HG3-08), validated for automotive powertrain and infotainment systems. |
| Compact DFN1006-2A footprint | 1.0 mm × 0.6 mm area saves PCB space near connectors; compatible with automated optical inspection (AOI) due to Sn (e3) plating. |
| High ESD robustness | ±15 kV contact discharge meets IEC 61000-4-2 Level 4 - exceeds typical industrial and automotive ESD test requirements. |
| Low dynamic resistance | 3.6 Ω ensures minimal voltage overshoot during sub-nanosecond ESD transients, improving protection margin for sensitive receivers. |
Applications
| USB 2.0 Data Lines | HDMI DDC/CEC Channel |
|---|---|
Use Scenario: Protecting USB 2.0 D+ and D− lines against user-handling ESD in portable docking stations and automotive USB hubs. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between connector and USB transceiver IC, clamping transients before they reach PHY input pins. Use Value: 12–18 pF capacitance avoids data eye closure; 62.5 V clamping prevents damage to 3.3 V tolerant USB PHYs during ±15 kV contact discharge. |
Use Scenario: Safeguarding HDMI DDC (I²C) and CEC control lines in flat-panel TVs and set-top boxes exposed to frequent cable insertion/removal. IC Role / Device Role / Timing Role: Single-line ESD clamp on bidirectional I²C bus, leveraging unidirectional architecture with ground-referenced cathode. Use Value: Low leakage (<0.01 μA @ 33 V) prevents I²C pull-up loading; 33 V VRWM accommodates 5 V DDC bus while maintaining noise margin. |
| Automotive Infotainment Display Port | Industrial Sensor Interface |
Use Scenario: ESD protection for LVDS or FPD-Link III video data lanes connecting head unit to digital dashboard displays. IC Role / Device Role / Timing Role: Per-lane unidirectional clamp adjacent to display connector, minimizing trace length to preserve signal integrity. Use Value: DFN1006-2A size allows placement within 2 mm of connector; AEC-Q101 qualification ensures operation at 125 °C junction temperature. |
Use Scenario: Protecting RS-485/RS-422 differential pairs in factory automation gateways subjected to field maintenance ESD. IC Role / Device Role / Timing Role: One VESD33C1-HD1-G3-08 per line (A or B) referenced to local ground, providing asymmetrical surge suppression. Use Value: 33 V VRWM matches common 24 V industrial bus rails; 100 W peak power rating handles multiple IEC 61000-4-5 surges 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 |
|---|---|---|---|
| SMAJ33A | DO-214AC package (4.5 mm × 2.7 mm); 33 V standoff; 100 W rating; higher capacitance (>200 pF); no AEC-Q101 option. | Used in board-level power/signal protection where PCB space is not constrained; unsuitable for high-speed data lines. | Select when cost-per-watt matters more than size or bandwidth; avoid for USB/HDMI. |
| TPD2E001DRYR | 2-channel, 0.8 pF/channel, 5.5 V VRWM, DRY (X2SON-6) package; designed for USB 2.0; not rated for 33 V operation. | Targeted at low-voltage, multi-line interfaces (e.g., smartphone USB ports); lacks high-voltage tolerance. | Choose only for <6 V systems requiring ultra-low capacitance; incompatible with 24/33 V industrial or automotive rails. |
Compared with SMAJ33A and TPD2E001DRYR, VESD33C1-HD1-G3-08 uniquely balances 33 V standoff, 12–18 pF capacitance, and DFN1006-2A size-enabling ESD protection on space-constrained, high-voltage, high-speed signal paths where alternatives compromise on voltage rating, bandwidth, or footprint.

FAQ
What is the maximum operating temperature for VESD33C1-HD1-G3-08?
VESD33C1-HD1-G3-08 has a junction temperature range of –55 °C to +150 °C and storage temperature range of –65 °C to +150 °C. This wide thermal envelope supports deployment in under-hood automotive modules and industrial environments where ambient temperatures exceed 105 °C. The DFN1006-2A package's low thermal resistance enables reliable operation at full rated power across this range.
Is VESD33C1-HD1-G3-08 AEC-Q101 qualified?
VESD33C1-HD1-G3-08 itself is not AEC-Q101 qualified; however, the pin-compatible variant VESD33C1-HD1HG3-08 is explicitly qualified per AEC-Q101. The "H" suffix denotes AEC-Q101 qualification, including stress testing for temperature cycling, humidity bias, and ESD robustness. For automotive applications requiring formal qualification, VESD33C1-HD1HG3-08 must be specified.
What is the clamping voltage of VESD33C1-HD1-G3-08 at its rated peak pulse current?
VESD33C1-HD1-G3-08 clamps to ≤62.5 V at its rated peak pulse current of 1.6 A (8/20 μs waveform). This value is measured per IEC 61000-4-5 and represents the maximum voltage imposed on the protected line during worst-case surge events. The typical clamping voltage is 56 V, providing a consistent safety margin for 3.3 V or 5 V interface ICs.
How does the capacitance of VESD33C1-HD1-G3-08 affect high-speed signal integrity?
VESD33C1-HD1-G3-08 exhibits 12–18 pF capacitance at 0 V reverse bias and 1 MHz, which introduces negligible loading on USB 2.0 (480 Mbps), HDMI DDC (100 kHz), and RS-485 (10 Mbps) signals. Measured insertion loss remains below 0.5 dB up to 500 MHz, preserving eye diagram opening and timing margins without requiring layout compensation.
Can VESD33C1-HD1-G3-08 be used for bidirectional signal lines like I²C?
VESD33C1-HD1-G3-08 is unidirectional and intended for ground-referenced signal lines (e.g., USB D+, HDMI TMDS). For true bidirectional buses like I²C, two devices are required-one anode-to-line, one cathode-to-line-or a dedicated bidirectional ESD diode (e.g., VESD0505B-HD1) must be selected. Using VESD33C1-HD1-G3-08 alone on I²C risks forward conduction during normal logic-high states.
