Product details
Overview
VTVS14GSMF-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 13.8 V stand-off voltage (VRWM), ±2 % breakdown voltage tolerance (VBR = 15.88–16.53 V at IT = 1 mA), 22.2 V maximum clamping voltage at 17.67 A peak pulse current (10/1000 μs), and ±30 kV IEC 61000-4-2 ESD immunity.
For engineers reviewing the VTVS14GSMF-M3-18 datasheet, VTVS14GSMF-M3-18 pinout, VTVS14GSMF-M3-18 application, or VTVS14GSMF-M3-18 equivalent, this device supports high-reliability board-level protection where low clamping voltage, fast response time, and AEC-Q101 qualification are critical - especially in automotive infotainment, industrial I/O, and portable electronics with tight voltage margins.
Technical Context
This TVS diode operates in avalanche mode to clamp transients above its reverse standoff voltage (VRWM = 13.8 V), delivering precise voltage limiting with low dynamic impedance. Its ±2 % VBR tolerance ensures tight design margins for systems requiring stable trigger thresholds under temperature variation and production spread.
The SMF package enables surface-mount reflow compatibility with peak soldering temperatures up to 260 °C and meets MSL level 1 per J-STD-020. With junction-to-lead thermal resistance of 20 K/W and TJ max = +175 °C, it sustains repeated surge events in thermally constrained PCB layouts without derating.
Key Specifications

IC Role / Device Role / Timing Role: Standby-mode protector that activates only during load dump or battery reversal events. Use Value: 13.8 V VRWM allows normal operation across full cold-crank range (6–16 V); 22.2 V VC prevents damage to 20 V-rated DC/DC converters. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ14A-E3/57T | ±5 % VBR tolerance (15.6–17.2 V), higher VC = 23.2 V at 17.2 A, same SMF package | Less precise clamping threshold; suitable where wider voltage margin exists | Select when cost sensitivity outweighs tight VBR control and lower clamping is not required |
| 1.5SMC14A | DO-214AB package (larger footprint), 400 W rating, ±5 % VBR, VC = 23.2 V at 17.2 A | Requires PCB layout change; better thermal dissipation but incompatible with space-constrained designs | Choose only if existing SMA footprint is fixed and thermal performance is prioritized over size |
Compared with SMAJ14A-E3/57T and 1.5SMC14A, VTVS14GSMF-M3-18 offers superior voltage precision (±2 % vs. ±5 %), lower clamping voltage (22.2 V vs. 23.2 V), and smaller DO-219AB footprint - making it optimal for next-gen automotive and compact industrial modules where layout density and electrical accuracy are critical.

FAQ
What is the maximum clamping voltage of the VTVS14GSMF-M3-18 under a 10/1000 μs surge?
The VTVS14GSMF-M3-18 has a maximum reverse clamping voltage (VC) of 22.2 V at a peak pulse current (IPPM) of 17.67 A with a 10/1000 μs waveform. This value is measured per standard test conditions and ensures downstream ICs remain within safe operating voltage limits during surge events. The VTVS14GSMF-M3-18 achieves this with low dynamic impedance and tight VBR tolerance, making it suitable for protecting 15 V-rated circuits.
Is the VTVS14GSMF-M3-18 AEC-Q101 qualified?
The VTVS14GSMF-M3-18 is part of a family that includes AEC-Q101 qualified variants; however, the -M3-18 suffix denotes tape-and-reel packaging (3K per 7″ reel) and RoHS-compliant tin plating - not qualification status. To obtain AEC-Q101 certification, the part must be ordered with the "H" environmental code (e.g., VTVS14GSMF-HM3-18). Always verify qualification status using the full ordering code and Vishay's official qualification reports for VTVS14GSMF-M3-18.
What does the "G" in VTVS14GSMF-M3-18 indicate?
The "G" in VTVS14GSMF-M3-18 specifies ±2 % tolerance on the reverse breakdown voltage (VBR), distinguishing it from "A"-suffixed parts (±5 %). For VTVS14GSMF-M3-18, VBR is guaranteed between 15.88 V and 16.53 V at IT = 1 mA. This tighter tolerance improves design predictability in voltage-critical applications such as automotive sensor interfaces where margin constraints are narrow.
Can the VTVS14GSMF-M3-18 be used in bidirectional configurations?
No - the VTVS14GSMF-M3-18 is a unidirectional TVS diode, intended for DC line protection with defined polarity (cathode connected to the protected line). It does not provide symmetrical clamping for AC or bidirectional signals. For bidirectional protection, Vishay offers separate dual-diode configurations (e.g., VTVS14GBSMF) or discrete back-to-back arrangements. Using VTVS14GSMF-M3-18 in reverse-biased mode will not suppress positive transients on the anode side.
What is the thermal resistance and maximum junction temperature of the VTVS14GSMF-M3-18?
The VTVS14GSMF-M3-18 has a junction-to-lead thermal resistance (RthJL) of 20 K/W when mounted on an infinite heat sink, and a maximum junction temperature (TJ) rating of +175 °C. This allows reliable operation in high-ambient environments such as automotive engine bays or industrial enclosures. The SMF package's low profile and MSL level 1 rating further support robust thermal and process performance in automated assembly.
