Product details
Overview
VESD24E1-HD1-G3-08 from Vishay Semiconductors is a single-line unidirectional ESD-protection diode in DFN1006-2A package, rated for 24 V working voltage, with ±30 kV IEC 61000-4-2 contact/air discharge immunity and 35 V typical clamping voltage at 4 A (8/20 μs), deployed in automotive infotainment data lines and industrial sensor interfaces.
For engineers reviewing the VESD24E1-HD1-G3-08 datasheet, VESD24E1-HD1-G3-08 pinout, VESD24E1-HD1-G3-08 application, or VESD24E1-HD1-G3-08 equivalent, key selection criteria include reverse standoff voltage (24 V), dynamic resistance (0.33 Ω), capacitance (28 pF at 0 V), AEC-Q101 qualification status, and DFN1006-2A footprint compatibility with high-density PCB layouts.
Technical Context
This device operates as a unidirectional transient voltage suppressor optimized for low-capacitance signal-line protection. Its silicon avalanche structure delivers fast response (<1 ns) to ESD events while maintaining low leakage (<0.05 μA at 24 V) and stable clamping performance across -55 °C to +150 °C junction temperature.
The DFN1006-2A package enables automated optical inspection of solder joints due to Sn-plated exposed sidewalls, and its MSL Level 1 rating supports standard reflow without dry-pack requirements. The device is characterized per IEC 61000-4-2, IEC 61000-4-5, and ISO 10605, with guaranteed clamping behavior verified via TLP testing at 100 ns pulse width.
Key Specifications

Applications
| Automotive Infotainment Data Lines | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting USB 2.0 and HDMI CEC lines in head units against ESD from user interaction and assembly handling. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed directly at connector entry point to shunt transients before reaching PHY IC. Use Value: 28 pF capacitance avoids signal degradation; 24 V VRWM matches supply rail; ±30 kV rating exceeds ISO 10605 requirements. | Use Scenario: Safeguarding analog output (4–20 mA) and digital I/O (RS-485) lines in factory-floor pressure/temperature sensors. IC Role / Device Role / Timing Role: Standalone ESD suppressor on field-side traces, co-located with TVS arrays for multi-level surge defense. Use Value: 150 °C max junction temperature ensures reliability in uncooled enclosures; low IR (<0.05 μA) prevents loading of precision current loops. |
| Consumer Portable Device Charging Ports | Medical Diagnostic Equipment Signal Paths |
Use Scenario: ESD protection for micro-USB and USB-C CC/DP lines in handheld ultrasound and patient monitors. IC Role / Device Role / Timing Role: First-stage protector at port entry, preceding internal EMI filters and level shifters.

IC Role / Device Role / Timing Role: Low-capacitance transient suppressor on high-speed digital control buses near RF-sensitive analog sections. Use Value: 28 pF capacitance avoids timing skew on 10 MHz SPI clocks; AEC-Q101 qualification supports IEC 60601-1-2 ESD compliance testing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD-protection diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-E3/57T | DO-214AC package; higher clamping (43 V), larger capacitance (150 pF), 1.5 kW peak power | Designed for board-level power rail protection, not signal-line use | Select only when protecting 24 V DC supplies-not data lines-due to size and capacitance mismatch |
| ESD9X24VD-2/TR | DFN1006-2L package; same 24 V VRWM, but lower clamping (32 V typ.), 18 pF capacitance, non-AEC-Q101 | Targeted at consumer electronics; lacks automotive qualification and full ISO 10605 validation | Acceptable for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
Compared with SMAJ24A-E3/57T and ESD9X24VD-2/TR, VESD24E1-HD1-G3-08 uniquely balances automotive qualification, ultra-low capacitance, and compact DFN1006-2A footprint-making it optimal for space-constrained, safety-critical signal-line protection where both ESD robustness and signal fidelity are required.

Yes, VESD24E1-HD1-G3-08 is AEC-Q101 qualified - explicitly stated in the "Features" section and ordering information table of the Vishay datasheet (Doc. #86221). The qualification applies to the VESD24E1-HD1 variant with G3 environmental code, confirming suitability for automotive electronics including infotainment and body control modules.
What is the clamping voltage of VESD24E1-HD1-G3-08 at 4 A?
The clamping voltage of VESD24E1-HD1-G3-08 is 35 V typical and 41 V maximum at 4 A peak pulse current (8/20 μs waveform), as specified in the Electrical Characteristics table. This value is measured under standardized IEC 61000-4-5 conditions and verified using transmission line pulse (TLP) testing at 100 ns pulse width.
Does VESD24E1-HD1-G3-08 support automated optical inspection (AOI)?
Yes, VESD24E1-HD1-G3-08 supports AOI due to its Sn (e3) lead plating on exposed sidewalls - a feature highlighted in the "Features" section. This enables visual confirmation of solder wetting and joint quality without requiring X-ray inspection, aligning with IPC-A-610 Class 2/3 process requirements.
What is the capacitance of VESD24E1-HD1-G3-08 at 0 V bias?
VESD24E1-HD1-G3-08 exhibits 28 pF typical capacitance at 0 V reverse bias and 1 MHz frequency, with a maximum of 31 pF, as documented in the Electrical Characteristics table. This low value ensures minimal impact on signal rise/fall times in high-speed interfaces such as USB 2.0 and I²C.
