Product details
Overview
VTVS47GSMF-M3-18 from Vishay Semiconductors is a unidirectional 400 W TransZorb® transient voltage suppressor diode in SMF (DO-219AB) package, designed for ESD and surge protection of low-voltage DC lines such as USB, HDMI, and automotive sensor interfaces. It features 46.8 V stand-off voltage, ±2 % breakdown voltage tolerance, 80 A peak pulse current (10/1000 μs), 80 V maximum clamping voltage, and 293 pF typical junction capacitance at 0 V.
For engineers reviewing the VTVS47GSMF-M3-18 datasheet, VTVS47GSMF-M3-18 pinout, VTVS47GSMF-M3-18 application, or VTVS47GSMF-M3-18 equivalent, this device is selected for high-reliability IEC 61000-4-2 ±30 kV contact/air discharge protection in space-constrained industrial and automotive electronics where low-profile SOD-123W-compatible packaging and AEC-Q101 qualification are required.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggering when reverse voltage exceeds its 54.88–57.12 V breakdown range (VBR, IT = 1 mA). Its low 20 K/W thermal resistance (RthJL) enables effective power dissipation under repetitive transients, while its 1.08 mm height and 3.9 × 1.9 mm footprint meet strict board-space constraints in modern PCB layouts.
The device delivers consistent clamping performance with 80 V max reverse clamping voltage (VC) at 80 A IPPM and maintains ≤0.05 μA leakage (IR) up to 46.8 V working voltage - critical for preserving signal integrity in high-speed data lines like CAN FD and LVDS interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ47A-E3/57T | Same 47 V nominal VRWM, but ±5 % VBR tolerance and 400 W rating in SMA package (DO-214AC) | Larger 4.5 × 2.7 mm footprint; not AEC-Q101 qualified; higher 1.5 mm profile | Select for cost-sensitive industrial designs where automotive qualification and ultra-low profile are not required |
| TPSMD47CA | Bidirectional configuration; same 47 V VRWM; 400 W rating; DO-214AB package | Clamps both polarities - suitable for AC-coupled or floating lines, but adds 0.5 V forward drop in normal operation | Choose when protecting differential pairs (e.g., RS-485) or legacy circuits lacking defined ground reference |
Compared with SMAJ47A-E3/57T and TPSMD47CA, VTVS47GSMF-M3-18 offers tighter ±2 % breakdown tolerance, AEC-Q101 qualification, and a 30 % smaller footprint - making it optimal for next-generation automotive and space-constrained industrial designs demanding precision clamping and reliability.

FAQ
What is the maximum clamping voltage of the VTVS47GSMF-M3-18 at its rated peak pulse current?
The VTVS47GSMF-M3-18 has a maximum reverse clamping voltage (VC) of 80 V when subjected to its rated 80 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and defines the highest voltage that will appear on the protected line during a surge event. The VTVS47GSMF-M3-18 achieves this clamping performance while maintaining low leakage and tight breakdown tolerance.
Is the VTVS47GSMF-M3-18 qualified for automotive applications?
Yes, the VTVS47GSMF-M3-18 is AEC-Q101 qualified, meaning it has passed stress tests including high-temperature reverse bias, temperature cycling, and mechanical shock per JESD22 standards. This qualification confirms its suitability for under-hood and cabin automotive applications such as body control modules, ADAS sensors, and infotainment interfaces. The VTVS47GSMF-M3-18 also supports extended temperature operation from −55 °C to +175 °C.
How does the ±2 % breakdown voltage tolerance of the VTVS47GSMF-M3-18 compare to ±5 % variants?
The ±2 % VBR tolerance of the VTVS47GSMF-M3-18 provides tighter control over the avalanche trigger point versus ±5 % versions (e.g., VTVS47ASMF-M3-18), reducing design uncertainty in systems with narrow voltage margins - such as 48 V mild hybrid architectures. This allows engineers to set more aggressive overvoltage thresholds without risking premature conduction. The VTVS47GSMF-M3-18 achieves this precision without sacrificing power rating or package size.
Can the VTVS47GSMF-M3-18 be used in high-speed data lines like USB 2.0 or HDMI?
Yes, the VTVS47GSMF-M3-18 has a typical junction capacitance of 293 pF at 0 V, which is compatible with USB 2.0 (480 Mbps) signal integrity requirements when placed with proper layout (short traces, ground plane). It is not recommended for HDMI 2.0+ or PCIe due to higher bandwidth demands. For USB-C implementations, the VTVS47GSMF-M3-18 is commonly deployed on VBUS and CC lines where its 46.8 V stand-off and 80 V clamping provide robust protection without signal degradation.
What is the package type and soldering compatibility of the VTVS47GSMF-M3-18?
The VTVS47GSMF-M3-18 uses the SMF (DO-219AB) package - a low-profile surface-mount case measuring 3.9 mm × 1.9 mm × 1.08 mm - and is fully compatible with standard reflow and wave soldering processes. Its peak reflow temperature rating is 260 °C, and it meets MSL level 1 per J-STD-020. The package is mechanically and thermally compatible with SOD-123W footprints, enabling drop-in replacement in existing designs. The VTVS47GSMF-M3-18 also features halogen-free molding compound and RoHS-compliant terminations.
