Product details
Overview
SMA6F130A-M3/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in SlimSMA (DO-221AC) package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features 130 V stand-off voltage (VWM), 144–159 V breakdown voltage (VBR), 207 V clamping voltage at 130 A (10/1000 μs), 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 SMA6F130A-M3/I datasheet, SMA6F130A-M3/I pinout, SMA6F130A-M3/I application, or SMA6F130A-M3/I equivalent, this page delivers verified electrical parameters, mechanical dimensions, thermal derating behavior, real-world clamping performance, and direct alternatives for circuit protection design in industrial and telecom systems.
Technical Context
This TVS diode operates as a unidirectional clamp with sharp Zener-like breakdown characteristics, triggered when reverse voltage exceeds VBR (144–159 V at 1 mA). Its low dynamic resistance (2.9 Ω typical) ensures rapid voltage limiting during transient events, while its 175 °C maximum junction temperature supports operation in high-ambient environments such as motor drives and base station power rails.
The device uses a planar junction structure in a halogen-free, RoHS-compliant SlimSMA package with matte tin-plated leads, meeting JESD201 Class 2 whisker resistance and MSL Level 1 reflow compatibility (260 °C peak). Its clamping behavior follows VC = RD × IPP + VBRmax, enabling accurate surge margin calculation for 10/1000 μs and 8/20 μs waveforms.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6F130A-M3/H | Identical electrical specs; differs only in tape-and-reel packaging (3500 pcs/reel vs. 14000 pcs/reel for /I) | Same circuit protection function; suited for lower-volume prototyping or small-batch production | Select /H for evaluation or pilot runs; /I preferred for high-volume manufacturing due to larger reel quantity |
| SMB6F130A-M3/5B | Same VWM/VBR/VC specs but in SMB (DO-214AA) package - 0.25 mm taller, 1.2 mm wider, higher RθJA (140 °C/W) | Compatible in low-density layouts where board space allows larger footprint; less suitable for ultra-thin designs | Choose SMB6F130A-M3/5B only if SlimSMA's 0.95 mm height constraint cannot be met; verify thermal margin on FR4 |
Compared with SMA6F130A-M3/I, the /H variant offers identical protection performance in smaller reels for flexibility, while SMB6F130A-M3/5B trades compactness for slightly relaxed thermal limits and broader industry footprint adoption-neither is pin-compatible due to differing package outlines.

FAQ
What is the clamping voltage of SMA6F130A-M3/I at 130 A (10/1000 μs)?
The clamping voltage of SMA6F130A-M3/I is 207 V when subjected to a 130 A peak pulse current with a 10/1000 μs waveform. This value is measured under standardized test conditions and defines the maximum voltage imposed on the protected circuit during that surge event. The SMA6F130A-M3/I achieves this clamping performance using a low dynamic resistance of 2.9 Ω, ensuring predictable and repeatable protection behavior across production lots.
Does SMA6F130A-M3/I support lead-free reflow soldering?
Yes, SMA6F130A-M3/I meets MSL Level 1 per J-STD-020 and is qualified for lead-free reflow with a maximum peak temperature of 260 °C. Its SlimSMA package uses matte tin-plated leads compliant with J-STD-002 and JESD22-B102, and the M3 suffix confirms halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance-ensuring robust solder joint integrity in high-volume SMT assembly.
How does the thermal resistance of SMA6F130A-M3/I affect PCB layout?
SMA6F130A-M3/I has a typical junction-to-ambient thermal resistance (RθJA) of 120–150 °C/W on FR4 with 2 oz copper. To maintain TJ ≤ 175 °C under 600 W surge duty, designers must minimize trace inductance and maximize copper area around anode/cathode pads. The SMA6F130A-M3/I datasheet recommends standard SlimSMA mounting pad layout per Vishay's DO-221AC outline to achieve specified thermal performance without heatsinks.
Can SMA6F130A-M3/I be used for bidirectional transient protection?
No, SMA6F130A-M3/I is a unidirectional TVS diode and is not rated for bidirectional operation. Its electrical characteristics-including breakdown voltage, clamping voltage, and leakage current-are specified only for reverse-biased (cathode-positive) conduction. For bidirectional protection, a dedicated bidirectional TVS such as SMBJ130CA or equivalent must be selected; substituting SMA6F130A-M3/I would leave the forward direction unprotected.
What is the ESD withstand capability of SMA6F130A-M3/I?
SMA6F130A-M3/I is rated to IEC 61000-4-2 Level 4: 15 kV for air discharge and 8 kV for contact discharge. This ESD performance is intrinsic to its silicon junction design and packaging, and no external components are required to meet these levels. The SMA6F130A-M3/I maintains full functionality after repeated ESD events, making it suitable for protecting exposed connectors and user-interface ports in industrial and telecom equipment.
