Product details
Overview
SMA6F100A-M3/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in SlimSMA (DO-221AC) package, designed for clamping voltage transients on power and signal lines. It features 100 V stand-off voltage (VWM), 111–123 V breakdown voltage (VBR), 162 V maximum clamping voltage at 10/1000 μs waveform, 600 W peak pulse power, and ESD immunity per IEC 61000-4-2 level 4 (15 kV air / 8 kV contact).
For engineers reviewing the SMA6F100A-M3/I datasheet, SMA6F100A-M3/I pinout, SMA6F100A-M3/I application, or SMA6F100A-M3/I equivalent, key selection criteria include clamping performance under 10/1000 μs and 8/20 μs surges, thermal derating above 25 °C, junction temperature limits up to 175 °C, and compatibility with automated SMT placement on FR4 PCBs.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds VBR (111–123 V at IT = 1 mA). Its low dynamic resistance (3.7 Ω typical) ensures tight clamping during transient events, while its 175 °C max junction temperature supports high-reliability industrial and automotive environments.
The device uses a planar junction structure in a halogen-free, RoHS-compliant SlimSMA (DO-221AC) package with matte tin-plated leads. It meets MSL level 1 per J-STD-020 and passes JESD201 class 2 whisker testing, enabling reflow soldering at peak temperatures up to 260 °C without degradation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6F100A-M3/6B | Same electrical specs; differs only in tape-and-reel packaging (14,000 pcs/reel vs. 3,500 pcs/reel for /I) | No functional difference; intended for high-volume automated assembly lines requiring larger reels | Select /I for prototyping, low-volume production, or space-constrained feeders; /6B for full-line SMT throughput optimization |
| SMAJ100A-M3/5B | Higher RθJA (160 °C/W), lower PPPM (400 W @ 10/1000 μs), same VWM/VBR range but 170 V VC | Less effective clamping margin for 100 V systems; suitable only where lower surge energy is expected | Use only if design tolerates 8 V higher clamping voltage and reduced 400 W surge handling; not drop-in for SMA6F100A-M3/I |
Compared with SMA6F100A-M3/I, SMA6F100A-M3/6B offers identical protection performance with optimized reel logistics, while SMAJ100A-M3/5B trades clamping precision and surge capacity for legacy footprint compatibility-making SMA6F100A-M3/I the preferred choice for new designs demanding tighter voltage control and higher energy absorption.

FAQ
What is the maximum clamping voltage of the SMA6F100A-M3/I under a 10/1000 μs surge?
The SMA6F100A-M3/I has a maximum clamping voltage (VC) of 162 V when subjected to a 10/1000 μs surge waveform at its rated peak pulse current of 3.7 A. This value is measured at TA = 25 °C and reflects the device's ability to limit transient overvoltage to protect downstream 100 V-rated components. The SMA6F100A-M3/I maintains this clamping performance across its specified operating temperature range, with derating applied above 25 °C per the published thermal curves.
Does the SMA6F100A-M3/I support lead-free reflow soldering?
Yes, the SMA6F100A-M3/I is qualified for lead-free reflow soldering with a maximum peak temperature of 260 °C, meeting J-STD-020 MSL level 1 requirements. Its matte tin-plated terminals comply with J-STD-002 and JESD22-B102 solderability standards, and it passes JESD201 class 2 whisker testing. The SMA6F100A-M3/I requires no pre-baking prior to reflow, simplifying manufacturing flow for high-yield SMT assembly.
How does the SMA6F100A-M3/I compare to bidirectional TVS diodes in surge protection?
The SMA6F100A-M3/I is unidirectional and optimized for DC or single-polarity signal lines where reverse conduction is not required-such as +100 V power rails or grounded-cathode configurations. Unlike bidirectional variants, it provides lower leakage (<0.2 μA at VWM) and tighter VBR tolerance, improving system efficiency and noise margin. The SMA6F100A-M3/I should not replace bidirectional TVS in AC-coupled or floating differential lines without circuit redesign.
What is the thermal resistance junction-to-ambient (RθJA) for the SMA6F100A-M3/I on a standard FR4 PCB?
The SMA6F100A-M3/I has a typical RθJA of 120 °C/W and a maximum of 150 °C/W when mounted on a standard FR4 PCB with 2 oz. copper and the recommended pad layout. This value assumes JEDEC 51-2A test conditions and directly impacts power derating: at 55 °C ambient, the device supports 8 W continuous dissipation, dropping linearly to zero at 175 °C junction temperature. The SMA6F100A-M3/I's low RθJA contributes to stable clamping performance under repeated surge events.
Can the SMA6F100A-M3/I be used in automotive applications requiring AEC-Q200 qualification?
The SMA6F100A-M3/I is not AEC-Q200 qualified. While it operates from −55 °C to +175 °C and meets MSL level 1, Vishay does not list this specific variant under AEC-Q200 stress testing. For automotive body control or infotainment systems requiring AEC-Q200 compliance, engineers should select Vishay's automotive-grade equivalents (e.g., SMA6F100AHE3/5B) or verify qualification status directly with Vishay. The SMA6F100A-M3/I remains suitable for non-safety-critical industrial or consumer applications with similar temperature and surge demands.
