Product details
Overview
VTVS12GSMF-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 12.4 V stand-off voltage (VRWM), 14.41–15.00 V reverse breakdown voltage (VBR) at 1 mA, 20.1 V maximum clamping voltage (VC) at 19.53 A peak pulse current, and ±30 kV IEC 61000-4-2 ESD immunity.
For engineers reviewing the VTVS12GSMF-M3-18 datasheet, VTVS12GSMF-M3-18 pinout, VTVS12GSMF-M3-18 application, or VTVS12GSMF-M3-18 equivalent, this device delivers precise low-voltage clamping with ±2 % VBR tolerance, halogen-free construction, MSL level 1 reflow compatibility, and AEC-Q101 qualification - critical for automotive infotainment, ADAS sensor nodes, and industrial I/O protection.
Technical Context
The VTVS12GSMF-M3-18 employs avalanche diode technology optimized for fast response (<1 ns) and low clamping ratio (VC/VBR ≈ 1.37), enabling robust protection against ESD transients and lightning-induced surges on 12 V nominal systems. Its unidirectional polarity and single-channel configuration support simple series placement across power or signal lines without polarity reversal concerns.
Thermal resistance of 20 K/W (junction-to-lead, infinite heat sink) and 175 °C maximum junction temperature allow sustained operation in under-hood automotive environments. The SMF package's 1.08 mm height and SOD-123W-compatible footprint enable high-density PCB layouts while maintaining mechanical robustness during automated assembly.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ12A-E3/57T | ±5 % VBR tolerance (11.4–12.7 V), 400 W rating, SMA package (DO-214AC), higher capacitance (1000 pF) | Less precise clamping margin; larger footprint (4.5 × 2.7 mm vs. 3.9 × 1.9 mm) limits high-density layouts | Select when cost sensitivity outweighs tight VBR tolerance and board space constraints |
| 1.5SMC12A | Same ±5 % VBR, 1500 W rating, SMC package (DO-214AB), 2.4 mm height, higher thermal mass | Over-specified power handling increases cost and size; not AEC-Q101 qualified | Choose only for non-automotive 12 V systems requiring higher surge margin beyond ISO 7637-2 |

FAQ
What is the clamping voltage of the VTVS12GSMF-M3-18 at its rated peak pulse current?
The VTVS12GSMF-M3-18 has a maximum reverse clamping voltage (VC) of 20.1 V at its peak pulse current (IPPM) of 19.53 A, measured using a 10/1000 μs waveform. This value ensures protected circuits remain within safe operating limits during standardized surge events, and is confirmed in the Vishay Document Number 85891, Table on page 3.
Is the VTVS12GSMF-M3-18 qualified for automotive applications?
Yes, the VTVS12GSMF-M3-18 is AEC-Q101 qualified, meeting stress test requirements for temperature cycling, high-temperature reverse bias, and ESD robustness. Its −55 °C to +175 °C operating range and halogen-free construction align with automotive OEM specifications, making it suitable for use in engine control, body electronics, and ADAS subsystems.
What does the "G" in VTVS12GSMF-M3-18 indicate?
The "G" in VTVS12GSMF-M3-18 denotes ±2 % tolerance on the reverse breakdown voltage (VBR), distinguishing it from "A"-suffix variants (±5 %). This tighter tolerance enables more accurate system-level voltage margining in 12 V applications where overvoltage headroom must be minimized without risking premature conduction.
Can the VTVS12GSMF-M3-18 be used in reflow soldering processes?
Yes, the VTVS12GSMF-M3-18 is rated for wave and reflow soldering with a peak temperature limit of 260 °C, per J-STD-020 MSL level 1. Its SMF (DO-219AB) package uses halogen-free molding compound and is compatible with standard lead-free reflow profiles, eliminating the need for pre-baking or special handling.
What is the typical capacitance of the VTVS12GSMF-M3-18 and how does it affect circuit performance?
The VTVS12GSMF-M3-18 has a typical capacitance of 807 pF at VR = 0 V and f = 1 MHz. This value is appropriate for protecting low-speed analog and digital signals (e.g., LIN, sensor outputs, 12 V power rails) but may introduce signal distortion on high-speed interfaces like USB 2.0 or HDMI; designers should verify bandwidth impact via simulation or measurement.
