Product details
Overview
VGSOT05-HG3-18 from Vishay Semiconductors is a unidirectional single-line ESD protection diode in SOT-23 package, designed for high-reliability data line protection with 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 serves as a transient voltage suppressor on USB, HDMI, or industrial sensor interfaces where low clamping and AEC-Q101 qualification are required.
For engineers reviewing the VGSOT05-HG3-18 datasheet, VGSOT05-HG3-18 pinout, VGSOT05-HG3-18 application, or VGSOT05-HG3-18 equivalent, this page delivers verified electrical parameters, BiAs-mode clamping behavior, SOT-23 terminal mapping, automotive-grade reliability validation, and real-world use cases aligned to IEC/ISO/AEC standards.
Technical Context
The VGSOT05-HG3-18 implements Bidirectional Asymmetrical (BiAs) protection mode: pin 1 grounded, pin 3 connected to signal line; reverse conduction initiates at VBR = 6–8 V, clamping transients up to 36 A (8/20 μs); forward conduction limits negative excursions to VF ≤ 1.2 V at 36 A. Its 279–350 pF capacitance at 0 V bias enables compatibility with high-speed interfaces below 100 Mbps.
This device operates across –55 °C to +150 °C junction temperature, meets AEC-Q101 stress testing for automotive electronics, and uses Sn (e3) terminations compliant with RoHS and J-STD-020 MSL level 1 reflow profiles up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5 V - Maximum continuous operating voltage before breakdown; sets upper limit for protected signal swing in 5 V logic systems. |
| VBR (min/typ/max) | 6 / 6.8 / 8 V - Reverse breakdown threshold at 1 mA; defines onset of clamping for positive transients. |
| VC @ IPPM = 36 A | 11–14 V - Peak clamping voltage during 8/20 μs surge; determines maximum stress imposed on downstream ICs. |
| VF @ IPPM = 36 A | ≤ 3.9 V - Forward clamping voltage under same surge; ensures negative transients remain near ground potential. |
| Capacitance @ 0 V | 279–350 pF - Signal-line loading at DC bias; supports USB 2.0 and RS-485 without excessive rise-time degradation. |
| ESD immunity | ±30 kV contact/air - Validated per IEC 61000-4-2 and ISO 10605; exceeds Level 4 system-level ESD requirements. |
| PPPM (8/20 μs) | 500 W - Peak pulse power handling; sustains short-duration surges common in industrial and automotive environments. |
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 (10K per 13″ reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Ground (Anode connection) | Low-impedance return path for transient current; must be connected to clean system ground plane. |
| Pin 2 | No internal connection | Electrically isolated; no PCB trace or thermal pad required; simplifies layout and avoids parasitic coupling. |
| Pin 3 | Protected signal line (Cathode connection) | Input/output node for data or control line; clamps both positive and negative transients via BiAs operation. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional BiAs-mode protection | Enables asymmetric clamping: 6.8 V reverse turn-on and ≤1.2 V forward conduction, minimizing voltage overshoot on bidirectional lines. |
| AEC-Q101 qualification | Validated for automotive applications including engine control units, infotainment interfaces, and ADAS sensor links. |
| e3 Sn termination | Lead-free, RoHS-compliant matte tin plating ensures solderability and long-term intermetallic stability under thermal cycling. |
| Low leakage at VRWM | IR ≤ 10 μA at 5 V reverse bias reduces standby power loss and prevents false triggering in battery-powered systems. |
| High ESD robustness | ±30 kV air/contact discharge withstand eliminates need for secondary protection layers in cost-sensitive consumer and industrial designs. |
Applications

Use Value: –55 °C to +150 °C operation supports under-hood deployment; 500 W pulse rating handles load-dump induced transients. |
Use Scenario: Protecting differential pair inputs of RS-485 transceivers in factory automation PLC modules exposed to field wiring ESD. IC Role / Device Role / Timing Role: Single-diode solution per line (TX/RX), leveraging low capacitance to preserve 25 Mbps signaling integrity. Use Value: 36 A peak pulse current capacity exceeds IEC 61000-4-5 Level 4 requirements; SOT-23 footprint minimizes board area. |
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; 600 W PPPM (8/20 μs); higher capacitance (~600 pF); unidirectional only. | Used in lower-speed, space-tolerant industrial controls; not suitable for high-density USB/HDMI layouts. | Select when higher surge margin is needed and board space allows larger package; verify layout clearance for DO-214AC. |
| TPD2E001DRSR | 2-channel, 15 pF per line, 3.6 V VRWM; SC-70 package; integrated ESD + EMI filtering. | Targeted at ultra-high-speed interfaces (e.g., USB 3.0, MIPI); requires dual-line coordination and tighter layout control. | Choose for multi-line, low-capacitance needs where VGSOT05-HG3-18's single-line, 5 V VRWM does not match system voltage. |
Compared with SMAJ5.0A and TPD2E001DRSR, VGSOT05-HG3-18 offers optimal balance of 5 V system compatibility, SOT-23 miniaturization, and automotive-grade reliability-making it preferred for cost-sensitive, high-volume 5 V data line protection where moderate speed and proven AEC-Q101 compliance are critical.
