Product details
Overview
SMA6F130A-M3/H 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 130 V stand-off voltage (VWM), 144–159 V breakdown voltage (VBR), 207 V maximum clamping voltage (VC) 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/H datasheet, SMA6F130A-M3/H pinout, SMA6F130A-M3/H application, or SMA6F130A-M3/H equivalent, this page delivers verified electrical parameters, mechanical dimensions, thermal derating behavior, clamping performance under standardized surge waveforms, and direct alternatives for overvoltage protection in industrial and telecom systems.
Technical Context
This TVS diode operates as a unidirectional clamping device with Zener-based avalanche breakdown. Its 130 V stand-off voltage enables use on 110–120 V nominal DC rails or high-voltage signal paths, while its 207 V clamping voltage at 130 A (10/1000 μs) limits downstream stress during transient events. The device exhibits low dynamic resistance (2.9 Ω) and a positive voltage temperature coefficient (αT = 10.8 × 10⁻⁴ /°C), ensuring stable VBR across operating junction temperatures from –55 °C to +175 °C.
Thermal design is supported by RθJA = 120–150 °C/W (FR4 PCB, 2 oz.) and RθJM = 12–15 °C/W (junction-to-mount), enabling reliable operation up to 175 °C junction temperature. Its M3 suffix confirms halogen-free, RoHS-compliant construction with matte tin-plated leads qualified to JESD201 Class 2 whisker test and J-STD-020 MSL Level 1 (260 °C peak reflow).

Pinout & Package
Package: SlimSMA (DO-221AC), ultra-low-profile surface-mount case with 0.95 mm typical height, UL 94 V-0 molding compound, and cathode band marking. Dimensions: 4.15–4.35 mm length × 2.50–2.70 mm width × 0.95 mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction; connected to lower-potential side of protected line. | Provides low-forward-drop path when used in bidirectional configurations with external components; not active during normal TVS clamping operation. |
| Cathode | Current exit terminal during reverse-biased clamping; marked by color band. | Connected to higher-potential rail (e.g., VBUS); determines polarity-sensitive placement-critical for correct unidirectional surge suppression. |
Key Features

FAQ
What is the maximum clamping voltage of the SMA6F130A-M3/H under a 10/1000 μs surge?
The SMA6F130A-M3/H has a maximum clamping voltage (VC) of 207 V when subjected to a 130 A peak pulse current with a 10/1000 μs waveform. This value is measured per standard test conditions (TA = 25 °C) and represents the upper limit of voltage imposed on the protected circuit during such a transient event. The SMA6F130A-M3/H maintains this clamping performance across its specified operating temperature range and is validated in Vishay document 89458.
Does the SMA6F130A-M3/H support lead-free reflow soldering?
Yes, the SMA6F130A-M3/H meets J-STD-020 MSL Level 1 with a maximum peak reflow temperature of 260 °C, making it fully compatible with standard lead-free soldering processes. Its M3 suffix confirms qualification to JESD201 Class 2 whisker testing and halogen-free, RoHS-compliant construction. The SMA6F130A-M3/H requires no pre-baking and supports single-pass reflow in high-volume SMT assembly.
How does the SMA6F130A-M3/H differ from bidirectional TVS diodes?
The SMA6F130A-M3/H is unidirectional, meaning it conducts only during reverse-biased overvoltage events and blocks forward current like a rectifier diode. Unlike bidirectional variants, it provides no protection against positive-going transients on grounded lines. Its VWM = 130 V and VBR = 144–159 V apply only in reverse bias; forward voltage drop is ~1.2 V at rated current. This makes SMA6F130A-M3/H ideal for DC power rail protection where polarity is fixed.
What is the thermal resistance junction-to-ambient (RθJA) for the SMA6F130A-M3/H?
The SMA6F130A-M3/H 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 footprint. This value is defined per JEDEC 51-2A and is essential for calculating junction temperature rise under steady-state power dissipation (PD = 8 W at TJ = 55 °C). The SMA6F130A-M3/H also achieves RθJM = 12–15 °C/W (junction-to-mount), supporting thermal coupling to heatsinks or metal-core PCBs.
Can the SMA6F130A-M3/H be used for IEC 61000-4-5 surge protection?
Yes, the SMA6F130A-M3/H is rated for 600 W peak pulse power with a 10/1000 μs waveform and 4 kW with an 8/20 μs waveform-both aligned with IEC 61000-4-5 test profiles. Its 207 V clamping voltage at 130 A (10/1000 μs) and low dynamic resistance (2.9 Ω) ensure effective energy diversion during combination wave surges. The SMA6F130A-M3/H is commonly deployed in conjunction with series impedance for full IEC 61000-4-5 compliance in industrial and telecom power inputs.
