Product details
Overview
VGSOT24-HG3-08 from Vishay Semiconductors is a single-line unidirectional ESD protection diode in SOT-23 package, rated for 24 V reverse stand-off voltage (VRWM), ±30 kV IEC 61000-4-2/ISO 10605 ESD immunity, and 400 W peak pulse power (8/20 μs). It delivers 8.4 A peak pulse current and clamps transients to ≤46 V at full surge, serving as primary ESD suppression on high-speed data lines such as USB 2.0 or HDMI interfaces.
For engineers reviewing the VGSOT24-HG3-08 datasheet, VGSOT24-HG3-08 pinout, VGSOT24-HG3-08 application, or VGSOT24-HG3-08 equivalent, this device is selected for robust transient suppression in automotive infotainment, industrial HMI, and consumer electronics where low capacitance (65–80 pF), AEC-Q101 qualification, and unidirectional clamping behavior are required.
Technical Context
The VGSOT24-HG3-08 implements BiAs-MODE (Bidirectional Asymmetrical) clamping: reverse conduction above 27–33 V breakdown (VBR) and forward conduction near ground (VF ≤ 1.2 V at 1 A), enabling precise voltage limiting for both positive and negative transients. Its SOT-23 footprint supports compact PCB layouts while maintaining MSL level 1 solderability and UL 94 V-0 mold compound compliance.
Designed for signal integrity preservation, it achieves 23 pF capacitance at 12 V reverse bias-critical for <100 Mbps data lines-and sustains operation from –55 °C to +150 °C junction temperature, meeting automotive-grade thermal reliability requirements without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 24 V - Maximum continuous working voltage before clamping begins; sets upper limit for protected line's normal operating range. |
| VBR (min/typ/max) | 27 / 30 / 33 V - Reverse breakdown threshold at 1 mA; defines onset of protective conduction during overvoltage events. |
| VC @ IPPM = 8.4 A | ≤46 V - Clamped voltage under full 8/20 μs surge; determines maximum stress imposed on downstream ICs. |
| Capacitance @ VR = 12 V | 23 pF - Signal-line loading at typical bias; enables use on USB 2.0 (480 Mbps) and DisplayPort auxiliary channels. |
| ESD immunity | ±30 kV contact/air discharge - Meets IEC 61000-4-2 Level 4 and ISO 10605 automotive ESD requirements out-of-the-box. |
| PPPM (8/20 μs) | 400 W - Peak transient energy handling capacity; sufficient for CAN FD, LIN, and sensor interface protection. |
| AEC-Q101 qualified | Yes - Validated for automotive applications including engine control modules and ADAS sensor interfaces. |
Pinout & Package
SOT-23 package: 3-pin surface-mount plastic case, 2.9 mm × 1.3 mm × 1.01 mm body, e3 Sn terminations, MSL level 1, UL 94 V-0 molding compound, compatible with standard reflow profiles (peak 260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Ground (cathode connection) | Low-inductance return path for transient current; must be connected to solid system ground plane. |
| Pin 2 | No connection (NC) | Internally unconnected; left floating per design-no routing or soldering required. |
| Pin 3 | Protected line (anode) | Input for signal/data line; clamps to ground when voltage exceeds VRWM or VBR thresholds. |
Key Features
| Feature | Design Value |
|---|---|
| BiAs-MODE clamping | Asymmetric forward/reverse clamping (VF ≤ 1.2 V / VC ≤ 46 V) preserves signal integrity while enabling precise rail-to-rail transient suppression. |
| AEC-Q101 qualification | Validated for automotive underhood and cabin environments, supporting long-term reliability in temperature-cycled systems. |
| Low dynamic capacitance | 65–80 pF at 0 V, dropping to 23 pF at 12 V bias-minimizes signal distortion on high-speed serial links. |
| e3 Sn termination | Lead-free, RoHS-compliant matte tin plating ensures solderability and intermetallic stability across multiple reflow cycles. |
| MSL level 1 rating | Unlimited floor life at ≤30 °C/60 % RH; eliminates bake requirements prior to assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-E3/57T | DO-214AC package, 24 V VBR, 400 W PPPM, but 150 pF capacitance and no AEC-Q101 qualification. | Higher board space requirement and unsuitable for automotive or high-speed data lines. | Select VGSOT24-HG3-08 for SOT-23 footprint, low capacitance, and automotive qualification. |
| TPD2E001DRSR | 2-channel, 5.5 V VRWM, 10 pF capacitance, but only ±8 kV ESD rating and not AEC-Q101 qualified. | Better for ultra-high-speed USB 3.0, but insufficient for 24 V industrial bus or automotive ESD stress. | Select VGSOT24-HG3-08 when 24 V standoff, ±30 kV immunity, and AEC-Q101 compliance are mandatory. |
Compared with SMAJ24A-E3/57T and TPD2E001DRSR, VGSOT24-HG3-08 uniquely balances 24 V standoff, ±30 kV ESD robustness, 23 pF low-bias capacitance, and AEC-Q101 qualification in a space-constrained SOT-23 package-making it optimal for automotive and industrial data-line protection where all four attributes are simultaneously required.

FAQ
What is the maximum reverse working voltage (VRWM) of the VGSOT24-HG3-08?
The VGSOT24-HG3-08 has a maximum reverse working voltage (VRWM) of 24 V, meaning it remains non-conductive under normal operating conditions up to this voltage. This value is confirmed in the "ELECTRICAL CHARACTERISTICS VGSOT24" table on page 7 of Vishay document 86326, where VRWM is specified as 24 V with IR ≤ 1 μA at VR = 24 V. The VGSOT24-HG3-08 maintains high impedance below this threshold to avoid signal interference.
Does the VGSOT24-HG3-08 meet automotive qualification standards?
Yes, the VGSOT24-HG3-08 is AEC-Q101 qualified, as explicitly stated in the "FEATURES" section (page 1) and "PACKAGE DATA" table (page 2) of Vishay document 86326. This qualification covers stress tests including HTGB, AC/DC life test, temperature cycling, and ESD-validating its suitability for automotive powertrain, body electronics, and infotainment systems. The VGSOT24-HG3-08 carries the "HG" environmental code denoting AEC-Q101 + RoHS compliance.
What is the clamping voltage of the VGSOT24-HG3-08 under full-rated surge current?
Under an 8.4 A peak pulse current (IPPM) with 8/20 μs waveform, the VGSOT24-HG3-08 clamps to a maximum of 46 V, as specified in the "ELECTRICAL CHARACTERISTICS VGSOT24" table (page 7, VC parameter). This clamping voltage ensures downstream ICs experience limited overvoltage stress during IEC 61000-4-5 surge events. The VGSOT24-HG3-08 achieves this while maintaining low forward voltage (<1.2 V at 1 A) for negative transients.
How does the VGSOT24-HG3-08 differ from bidirectional ESD diodes?
The VGSOT24-HG3-08 is unidirectional and uses BiAs-MODE: it clamps positive transients above 27–33 V (VBR) to ground via reverse conduction, and negative transients near 0 V via low-VF forward conduction. Unlike symmetric bidirectional diodes, this asymmetry enables tighter control of clamping levels-critical for protecting circuits referenced to ground. The VGSOT24-HG3-08 pinout (Pin 1 = GND, Pin 3 = signal) enforces this grounding topology.
What is the capacitance of the VGSOT24-HG3-08 at operating bias?
The VGSOT24-HG3-08 exhibits 23 pF capacitance at 12 V reverse bias (VR), as specified in the "ELECTRICAL CHARACTERISTICS VGSOT24" table (page 7, CD parameter). At 0 V bias, capacitance is 65–80 pF. This voltage-dependent capacitance minimizes signal degradation on data lines operating near their VRWM-enabling reliable use on USB 2.0, HDMI DDC, and industrial RS-485 interfaces. The VGSOT24-HG3-08's low-bias capacitance directly supports high-speed signal integrity.
