Product details
Overview
VGSOT05-HG3-08 from Vishay Semiconductors is a unidirectional single-line ESD protection diode in SOT-23 package, rated for 5 V reverse stand-off voltage (VRWM), ±30 kV IEC 61000-4-2/ISO 10605 ESD immunity, and 500 W peak pulse power (8/20 μs). It delivers 36 A peak pulse current and clamps transients to ≤14 V at full stress, serving as primary interface-level surge suppression for USB 2.0 data lines.
For engineers reviewing the VGSOT05-HG3-08 datasheet, VGSOT05-HG3-08 pinout, VGSOT05-HG3-08 application, or VGSOT05-HG3-08 equivalent, this device supports high-reliability automotive infotainment ports, industrial HMI touch interfaces, and consumer USB-C accessory detection circuits where low capacitance (279–350 pF) and AEC-Q101 qualification are mandatory.
Technical Context
The VGSOT05-HG3-08 implements BiAs-MODE (Bidirectional Asymmetrical) clamping: reverse conduction initiates above 6.8 V (typ.) breakdown, while forward clamping holds negative transients near ground via 1.0–1.2 V forward voltage. Its SOT-23 footprint enables direct integration into space-constrained PCB layouts without requiring external bias or control logic.
This device operates across –55 °C to +150 °C junction temperature, meets AEC-Q101 stress requirements including human body model class H3B (>8 kV), and uses e3 Sn-plated terminations compatible with lead-free reflow profiles up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5 V - Maximum continuous operating voltage before clamping begins; matches 3.3 V/5 V logic rail interfaces. |
| VBR (min/typ/max) | 6 V / 6.8 V / 8 V - Ensures reliable turn-on above system supply while avoiding false triggering during normal operation. |
| VC @ IPPM = 36 A | ≤14 V - Clamping voltage under worst-case 8/20 μs surge; protects downstream 5 V tolerant ICs. |
| Capacitance @ 0 V | 279–350 pF - Low enough for USB 2.0 (480 Mbps) signal integrity; <165 pF at 2.5 V bias further reduces loading. |
| ESD immunity | ±30 kV contact/air - Exceeds IEC 61000-4-2 Level 4 and ISO 10605 requirements for automotive and industrial end-equipment. |
| PPPM (8/20 μs) | 500 W - Sustains high-energy transients from cable discharge events without degradation. |
| TJ max. | +150 °C - Enables deployment in under-hood automotive modules and sealed industrial enclosures. |
Pinout & Package
SOT-23 package: 3-pin, surface-mount, green molding compound (UL 94 V-0), 9.2 mg weight, MSL level 1, compatible with standard 8 mm tape-and-reel handling (3K per 7″ reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Ground (Anode common) | Low-inductance return path for transient current; must connect directly to solid ground plane. |
| Pin 2 | No connection (NC) | Internal die pad; electrically isolated and thermally inactive; no PCB trace required. |
| Pin 3 | Protected line (Cathode) | Connects to signal/data line (e.g., USB D+); clamps positive surges to ground and negative surges to ~1.2 V. |
Key Features
| Feature | Design Value |
|---|---|
| BiAs-MODE clamping | Asymmetric forward/reverse clamping enables precise protection of unidirectional data lines without compromising noise margin. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HBM >8 kV, temperature cycling, and high-temperature operating life. |
| e3 Sn termination | Lead-free, RoHS-compliant plating ensures compatibility with Pb-free soldering processes and long-term intermetallic stability. |
| Low leakage at VRWM | ≤10 μA reverse current at 5 V ensures minimal standby power loss in battery-powered portable systems. |
| Thermal robustness | 150 °C max junction temperature and MSL level 1 rating support reflow, conformal coating, and harsh-environment deployment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | DO-214AC package; 5.0 V VRWM; 400 W PPPM; higher capacitance (~600 pF); not AEC-Q101 qualified. | Used in cost-sensitive industrial power rails; unsuitable for high-speed data lines or automotive qualification requirements. | Select only for non-automotive, non-data applications where board space and speed are secondary to cost. |
| TPD2E001DRYR | 2-channel, 5 V VRWM, 300 W PPPM, 10 pF typical capacitance; integrated dual-diode array in SOT-553; AEC-Q100 qualified. | Optimized for ultra-low-capacitance USB 2.0/3.0; requires two channels; lower single-line surge rating than VGSOT05-HG3-08. | Prefer when protecting multiple lines simultaneously or when sub-15 pF capacitance is critical; verify thermal derating for 36 A pulses. |
Compared with SMAJ5.0A and TPD2E001DRYR, VGSOT05-HG3-08 uniquely balances AEC-Q101 compliance, 500 W surge capacity, and 279–350 pF capacitance in a single-line SOT-23 form factor-making it optimal for automotive USB and industrial serial interfaces demanding both ruggedness and signal fidelity.

FAQ
What is the maximum clamping voltage of VGSOT05-HG3-08 under full-rated surge conditions?
The VGSOT05-HG3-08 exhibits a maximum reverse clamping voltage (VC) of 14 V when subjected to its full 36 A peak pulse current (8/20 μs waveform), as specified in the absolute maximum ratings table. This value ensures downstream 5 V logic components remain within safe operating limits during transient events. The VGSOT05-HG3-08 maintains this performance across its full operating temperature range of –55 °C to +150 °C.
Is VGSOT05-HG3-08 qualified for automotive applications?
Yes, VGSOT05-HG3-08 is AEC-Q101 qualified and rated for human body model (HBM) Class H3B (>8 kV). It undergoes stress testing for temperature cycling, high-temperature operating life, and mechanical shock per AEC-Q101 standards. The VGSOT05-HG3-08 is explicitly intended for automotive infotainment, body control, and ADAS interface protection where ESD robustness and thermal endurance are critical.
How does the BiAs-MODE architecture of VGSOT05-HG3-08 improve protection performance?
BiAs-MODE provides asymmetric clamping: positive transients trigger reverse conduction above 6.8 V (typ.), while negative transients are clamped near ground via low forward voltage (~1.0–1.2 V). This avoids over-clamping on negative excursions and preserves signal integrity on unidirectional data lines. The VGSOT05-HG3-08 leverages this mode to protect USB 2.0 and automotive serial links without distorting logic thresholds.
What is the capacitance profile of VGSOT05-HG3-08 across operating bias?
The VGSOT05-HG3-08 has a typical capacitance of 279–350 pF at 0 V reverse bias and drops to ≤165 pF at 2.5 V reverse bias (1 MHz test frequency). This voltage-dependent capacitance minimizes signal loading during active operation while maintaining effective ESD suppression at zero bias. The VGSOT05-HG3-08's capacitance remains stable across temperature and meets USB 2.0 eye diagram requirements.
Can VGSOT05-HG3-08 be used in bidirectional signal paths like RS-485?
No-VGSOT05-HG3-08 is a unidirectional device designed for single-ended, ground-referenced signals (e.g., USB D+, HDMI TMDS+, analog audio). Its BiAs-MODE relies on fixed anode-to-ground (Pin 1) and cathode-to-signal (Pin 3) polarity. For true bidirectional lines such as RS-485 differential pairs, a symmetric or dedicated bidirectional TVS like VGSOT24-HG3-08 would be required instead of VGSOT05-HG3-08.
