Product details
Overview
VGSOT05C-HG3-18 from Vishay Semiconductors is a two-line unidirectional ESD protection diode in SOT-23 package, featuring common-anode dual-channel configuration, 5 V maximum reverse working voltage (VRWM), ±30 kV IEC 61000-4-2 ESD immunity, and 500 W peak pulse power (8/20 μs). It protects high-speed data lines such as USB 2.0 and HDMI interfaces against electrostatic discharge.
For engineers reviewing the VGSOT05C-HG3-18 datasheet, VGSOT05C-HG3-18 pinout, VGSOT05C-HG3-18 application, or VGSOT05C-HG3-18 equivalent, key selection criteria include bidirectional asymmetrical (BiAs) clamping behavior, low 276 pF line capacitance at 0 V, AEC-Q101 qualification, and compatibility with automated SMT assembly using MSL level 1 reflow profiles.
Technical Context
The VGSOT05C-HG3-18 implements a dual-diode common-anode topology enabling two-line unidirectional protection with independent clamping paths to ground (pin 3). Its BiAs-MODE operation delivers asymmetric forward (VF ≈ 1.0–3.9 V) and reverse (VC ≈ 7.3–14.0 V at IPP = 36 A) clamping voltages for optimized transient suppression on signal pairs.
When configured in BiSy-MODE (pins 1–2 only, pin 3 open), it functions as a single-line bidirectional protector with 5.5 V VRWM and 138–175 pF capacitance - suitable for legacy analog or low-speed digital lines requiring symmetrical surge response.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5 V - defines maximum continuous operating voltage before leakage exceeds 10 μA; sets upper limit for protected data-line DC bias. |
| VBR (min) | 6 V - reverse breakdown threshold at 1 mA; ensures reliable turn-on during ESD events above system operating range. |
| VC @ IPP = 36 A | 11–14 V - peak clamping voltage under 8/20 μs surge; determines maximum voltage seen by downstream IC during worst-case transients. |
| CD @ 0 V | 276–350 pF - line-to-ground capacitance at zero bias; directly impacts signal integrity on high-speed interfaces like USB 2.0. |
| ESD immunity | ±30 kV contact/air (IEC 61000-4-2 & ISO 10605) - meets automotive and industrial immunity requirements without external filtering. |
| PPP (8/20 μs) | 500 W - peak pulse power handling capacity; supports robust protection against lightning-induced surges per IEC 61000-4-5. |
| TJ max. | +150 °C - enables operation in under-hood automotive environments and thermally constrained PCB layouts. |
Pinout & Package
SOT-23 package (JEDEC TO-236AB), 3-pin, green molding compound, UL 94 V-0 rated, 9.2 mg weight, MSL level 1, peak reflow temperature ≤ 260 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Channel 1 | Connects to first protected signal line (L1); forms clamping path to ground via internal diode when L1 exceeds VRWM. |
| Pin 2 | Anode of Channel 2 | Connects to second protected signal line (L2); shares common cathode (pin 3) for dual-line protection. |
| Pin 3 | Common Cathode | Must be connected to system ground; serves as shared return path for both ESD current channels in BiAs-MODE. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line unidirectional protection | Enables simultaneous safeguarding of differential or parallel signal pairs (e.g., USB D+/D−) with single-component footprint savings. |
| Bidirectional Asymmetrical (BiAs) clamping | Delivers low forward-voltage clamping (~1.0 V) for negative transients and controlled reverse-voltage clamping (~11–14 V) for positive surges - minimizing stress on receiver inputs. |
| AEC-Q101 qualified | Validated for automotive applications including infotainment, ADAS camera links, and body control modules requiring extended temperature and reliability compliance. |
| e3 Sn termination | Lead-free matte tin plating ensures RoHS compliance and solderability stability across multiple reflow cycles without whisker risk. |
| MSL level 1 rating | Allows indefinite floor life before reflow; eliminates baking requirements and simplifies manufacturing logistics for high-volume SMT production. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J5.0A | Single-line unidirectional TVS; 5.0 V VRWM, 600 W PPP (8/20 μs), 550 pF capacitance - higher capacitance, no dual-channel integration. | Requires two devices for dual-line protection; larger PCB area; less optimal for high-speed differential signals. | Select when cost-per-channel is prioritized over board space and signal integrity. |
| TPD2E001DRSR | Two-line unidirectional ESD array; 5.5 V VRWM, 200 W PPP, 12 pF capacitance - lower power rating, ultra-low capacitance for >480 Mbps interfaces. | Better suited for USB 3.0/PCIe; insufficient for 4 kV surge immunity in harsh industrial environments. | Select when protecting ultra-high-speed serial links where sub-15 pF capacitance is mandatory. |
Compared with SMA6J5.0A and TPD2E001DRSR, the VGSOT05C-HG3-18 uniquely balances dual-line integration, 500 W surge capability, and 276–350 pF capacitance - making it optimal for USB 2.0, HDMI, and FPD-Link II where space, power handling, and moderate bandwidth coexist.

FAQ
What is the maximum reverse working voltage (VRWM) of the VGSOT05C-HG3-18?
The VGSOT05C-HG3-18 has a maximum reverse working voltage (VRWM) of 5 V, verified per electrical characteristics table for VGSOT05C at Tamb = 25 °C. This value defines the highest continuous DC voltage the device can withstand without exceeding 10 μA reverse leakage current, making it suitable for 3.3 V and 5 V logic interfaces including USB 2.0 and HDMI data lanes. The VGSOT05C-HG3-18 maintains this rating across its full operating temperature range of −55 °C to +150 °C.
How does the VGSOT05C-HG3-18 support both BiAs-MODE and BiSy-MODE configurations?
The VGSOT05C-HG3-18 supports BiAs-MODE by connecting pin 3 to ground and pins 1 and 2 to separate signal lines (L1/L2), enabling dual-line unidirectional clamping with asymmetric forward/reverse voltage thresholds. For BiSy-MODE, pin 3 is left unconnected while pins 1 and 2 form a bidirectional path - achieving symmetrical clamping with 5.5 V VRWM. This dual-mode flexibility is intrinsic to the common-anode SOT-23 structure and is documented in the Vishay VGSOT03C–VGSOT36C datasheet revision 1.1.
Is the VGSOT05C-HG3-18 qualified to AEC-Q101 standards?
Yes, the VGSOT05C-HG3-18 is explicitly AEC-Q101 qualified, as confirmed in the "FEATURES" section and "ORDERING INFORMATION" table of the Vishay document 86325. This qualification covers stress tests including HTGB, AC/DC life test, temperature cycling, and ESD HBM/MM, validating its suitability for automotive applications such as infotainment, ADAS camera links, and body control modules operating from −55 °C to +150 °C junction temperature.
What is the typical capacitance of the VGSOT05C-HG3-18 at 0 V reverse bias?
The typical capacitance of the VGSOT05C-HG3-18 at 0 V reverse bias and 1 MHz is 276–350 pF, as specified in the "ELECTRICAL CHARACTERISTICS VGSOT05C" table under "Capacitance" parameter. This value applies to each channel (pin 1–3 and pin 2–3) in BiAs-MODE and directly impacts high-speed signal integrity - for example, limiting usable bandwidth on USB 2.0 lines but remaining acceptable for full-speed (480 Mbps) operation when properly routed.
Can the VGSOT05C-HG3-18 be used in parallel to increase surge current handling?
Yes, the VGSOT05C-HG3-18 supports parallel operation of its two internal diodes to double peak pulse current (IPPM) capability from 36 A to 72 A and double peak pulse power (PPP) from 500 W to 1000 W under 8/20 μs waveform. This configuration halves effective series inductance and resistance - reducing clamping voltage - though it doubles line capacitance (to ~552–700 pF) and reverse leakage current. Implementation requires matched PCB trace lengths and symmetric grounding per Vishay's BiAs-MODE parallel guidance.
