Product details
Overview
VTVS14GSMF-M3-08 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. It features 13.8 V stand-off voltage (VRWM), 15.88–16.53 V reverse breakdown voltage (VBR) at 1 mA, and clamps to ≤22.2 V at 17.67 A peak pulse current (10/1000 μs), supporting automotive infotainment power rail protection.
For engineers reviewing the VTVS14GSMF-M3-08 datasheet, VTVS14GSMF-M3-08 pinout, VTVS14GSMF-M3-08 application, or VTVS14GSMF-M3-08 equivalent, this device is selected for robust ±30 kV IEC 61000-4-2 ESD immunity, low-profile SOD-123W-compatible footprint, and AEC-Q101 qualification - critical for space-constrained automotive and industrial control interface designs.
Technical Context
This TVS diode operates as a unidirectional clamping device with avalanche breakdown behavior, triggered when reverse voltage exceeds VRWM = 13.8 V. Its thermal resistance RthJL = 20 K/W enables reliable power dissipation under repetitive transients, and junction temperature range of –55 °C to +175 °C supports under-hood automotive deployment.
The device delivers fast response time via "Low-Noise" technology and achieves 22.2 V clamping at IPPM = 17.67 A (10/1000 μs), with typical capacitance of 752 pF at 0 V - optimized for signal integrity preservation on 12 V supply rails while maintaining high surge immunity.

FAQ
What is the maximum clamping voltage of the VTVS14GSMF-M3-08 under standard test conditions?
The VTVS14GSMF-M3-08 has a maximum reverse clamping voltage (VC) of 22.2 V when subjected to a 10/1000 μs peak pulse current of 17.67 A. This value is measured per IEC 61000-4-5 and ensures downstream circuitry remains within safe operating limits during surge events. The VTVS14GSMF-M3-08 maintains this clamping performance across its full operating temperature range.
Is the VTVS14GSMF-M3-08 qualified for automotive applications?
Yes, the VTVS14GSMF-M3-08 is AEC-Q101 qualified, having passed stress tests including temperature cycling, high-temperature operating life, and mechanical shock. This qualification confirms its suitability for under-hood and cabin-mounted automotive systems. The VTVS14GSMF-M3-08 is explicitly listed in Vishay's AEC-Q101 qualified product matrix for the eSMP® family.
What does the "G" in VTVS14GSMF-M3-08 indicate?
The "G" in VTVS14GSMF-M3-08 denotes ±2 % tolerance on the reverse breakdown voltage (VBR), distinguishing it from "A"-suffixed variants (e.g., VTVS14ASMF-M3-08) which have ±5 % VBR tolerance. This tighter tolerance enables more precise overvoltage threshold setting in safety-critical designs. The VTVS14GSMF-M3-08 achieves 15.88–16.53 V VBR at 1 mA, verified per datasheet Rev. 2.2.
Can the VTVS14GSMF-M3-08 be used in reflow soldering processes?
Yes, the VTVS14GSMF-M3-08 is fully compatible with standard lead-free reflow soldering profiles, with a maximum peak temperature of 260 °C. Its SMF (DO-219AB) package meets J-STD-020 MSL Level 1 requirements, allowing unlimited floor life at ≤30 °C/60 % RH. The VTVS14GSMF-M3-08 has been validated for both wave and reflow assembly in Vishay's qualification reports.
What is the typical junction-to-lead thermal resistance (RthJL) of the VTVS14GSMF-M3-08?
The VTVS14GSMF-M3-08 has a thermal resistance RthJL of 20 K/W when mounted on an infinite heat sink, as specified in the Absolute Maximum Ratings table. This value reflects efficient heat transfer from the silicon die to the PCB copper via the leads, supporting sustained surge handling in thermally constrained layouts. The VTVS14GSMF-M3-08 maintains this RthJL across its full -55 °C to +175 °C operating range.
