Product details
Overview
SMA6F110A-M3/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SlimSMA (DO-221AC) package, designed for clamping voltage transients on power and signal lines. It features 110 V stand-off voltage (VWM), 122–135 V breakdown voltage (VBR), 177 V maximum clamping voltage at 3.4 A (10/1000 μs), 600 W peak pulse power, and IEC 61000-4-2 level 4 ESD immunity (15 kV air / 8 kV contact).
For engineers reviewing the SMA6F110A-M3/I datasheet, SMA6F110A-M3/I pinout, SMA6F110A-M3/I application, or SMA6F110A-M3/I equivalent, this device is selected for robust overvoltage protection in industrial sensor interfaces, telecom line cards, and automotive body control modules where low-profile mounting and high surge resilience are critical.
Technical Context
This TVS diode operates as a unidirectional clamping device with a Zener-based avalanche structure, activated when reverse voltage exceeds VBR. Its thermal resistance junction-to-ambient is 120–150 °C/W (FR4 PCB), and it supports continuous operation up to TJ = 175 °C with derating above TA = 25 °C.
The device delivers 600 W peak pulse power under 10/1000 μs waveform and 4 kW under 8/20 μs waveform, enabled by low dynamic resistance (RD = 12.4 Ω) and fast response time (< 1 ns). Its M3 suffix confirms halogen-free, RoHS-compliant construction and JESD201 class 2 whisker resistance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6F110A-M3/6A | Same electrical specs; differs only in tape-and-reel packaging (3500 pcs vs. 14000 pcs) and package code "6A" instead of "I" | Identical performance; suited for smaller-batch prototyping or low-volume production runs | Select when reel size or inventory planning requires 7″ tape format |
| SMC6F110A-M3/5B | Higher-power SMC (DO-214AB) package: 1500 W (10/1000 μs), larger footprint (7.11 × 6.22 mm vs. 4.35 × 2.60 mm), same VWM/VBR/VC | Used where board space allows and higher surge margin is prioritized over profile | Choose for legacy designs using SMC footprints or where 1500 W rating is mandated |
Compared with SMA6F110A-M3/I, SMA6F110A-M3/6A offers identical protection performance in a smaller reel format, while SMC6F110A-M3/5B trades compactness for 2.5× higher pulse power-making the SlimSMA variant optimal for modern miniaturized systems requiring 600 W clamping in <1 mm height.

FAQ
What is the clamping voltage of SMA6F110A-M3/I under a 10/1000 μs surge?
The SMA6F110A-M3/I exhibits a maximum clamping voltage (VC) of 177 V when subjected to a 3.4 A peak pulse current with a 10/1000 μs waveform. This value is measured per standard test conditions and defines the upper voltage limit imposed on the protected circuit during such transients. The SMA6F110A-M3/I maintains this clamping performance consistently across its rated operating temperature range.
Does SMA6F110A-M3/I support automated SMT assembly?
Yes, SMA6F110A-M3/I is fully compatible with automated surface-mount assembly. Its SlimSMA (DO-221AC) package features matte tin-plated leads that meet J-STD-002 and JESD22-B102 solderability standards, and its M3 suffix confirms JESD201 class 2 whisker resistance. The device's low 0.95 mm profile also minimizes tombstoning risk during reflow. SMA6F110A-M3/I is supplied in 13″ tape-and-reel format optimized for high-speed pick-and-place machines.
What is the maximum operating junction temperature for SMA6F110A-M3/I?
The maximum operating junction temperature (TJ max.) for SMA6F110A-M3/I is 175 °C. This rating enables reliable operation in demanding environments such as under-hood automotive electronics or enclosed industrial drives. Derating of power dissipation begins above TA = 25 °C per the published curve (Fig. 5), and the device meets MSL Level 1 per J-STD-020 with a 260 °C reflow peak. SMA6F110A-M3/I retains full specification compliance across its full -55 °C to +175 °C junction temperature range.
How does the ESD rating of SMA6F110A-M3/I compare to IEC 61000-4-2 level 4?
SMA6F110A-M3/I is certified to IEC 61000-4-2 level 4, delivering 15 kV air discharge and 8 kV contact discharge immunity. These values exceed the minimum requirements for level 4 and reflect rigorous qualification testing per the standard. The device's low capacitance and fast response (<1 ns) ensure effective ESD energy diversion without signal distortion. SMA6F110A-M3/I achieves this performance while maintaining only 0.2 μA leakage at its 110 V stand-off voltage.
Is SMA6F110A-M3/I halogen-free and RoHS-compliant?
Yes, SMA6F110A-M3/I carries the M3 suffix, which explicitly denotes halogen-free, RoHS-compliant construction and industrial-grade reliability. The molding compound meets UL 94 V-0 flammability rating, and all materials comply with Vishay's material categorization standard (document #99912). This makes SMA6F110A-M3/I suitable for environmentally regulated markets including EU, China, and Japan, and aligns with strict corporate sustainability requirements. The M3 designation applies to the entire device-not just packaging.
