Product details
Overview
SMA6F100A-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 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 10.5 × 10⁻⁴/°C voltage temperature coefficient - deployed in industrial sensor interface protection.
For engineers reviewing the SMA6F100A-M3/H datasheet, SMA6F100A-M3/H pinout, SMA6F100A-M3/H application, or SMA6F100A-M3/H equivalent, key selection criteria include clamping performance under 10/1000 μs surge, unidirectional polarity, SlimSMA footprint compatibility, ESD immunity per IEC 61000-4-2 level 4, and thermal derating above 25 °C ambient.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR (111–123 V), it avalanches to limit transient energy. Its low dynamic resistance (3.7 Ω typical) ensures rapid response and tight clamping during 10/1000 μs surges up to 600 W.
Designed for automated SMT assembly, the device meets MSL level 1 (reflow peak 260 °C), uses matte tin-plated leads compliant with J-STD-002/JESD22-B102, and achieves 8 kV contact / 15 kV air discharge ESD robustness per IEC 61000-4-2 level 4.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - maximum continuous reverse operating voltage before conduction begins |
| VBR min/max | 111 V / 123 V at 1 mA - guaranteed avalanche initiation range defining turn-on threshold |
| VC @ IPPM (10/1000 μs) | 162 V - clamping voltage seen by protected circuit during 600 W transient event |
| PPPM (10/1000 μs) | 600 W - surge energy handling capacity for standard lightning-surge simulation |
| αT | 10.7 × 10⁻⁴/°C - predictable VBR drift with junction temperature for thermal design margining |
| TJ max | 175 °C - maximum allowable junction temperature enabling high-reliability operation in sealed enclosures |

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 (13" reel, 14,000 pcs vs. 7" reel, 3500 pcs) | No functional difference; identical placement, soldering, and circuit behavior | Select SMA6F100A-M3/6B for high-volume production runs requiring larger reels and reduced changeover frequency. |
| SMA6F100AHE3/A | Same VWM/VBR/VC specs; uses DO-214AC (SMA) package instead of SlimSMA (DO-221AC); 2.3 mm height vs. 0.95 mm | Higher profile limits use in ultra-thin assemblies; thermal resistance RθJA ~150 °C/W vs. 120–150 °C/W for SlimSMA | Choose SMA6F100AHE3/A only if legacy SMA footprint compatibility is mandatory and board height allows ≥2.3 mm clearance. |
Compared with SMA6F100A-M3/H, SMA6F100A-M3/6B offers identical protection performance with optimized logistics for volume manufacturing, while SMA6F100AHE3/A trades height reduction for broader package availability - making SMA6F100A-M3/H the preferred choice for space-constrained industrial and telecom designs requiring MSL-1 reflow and low-profile mounting.

FAQ
What is the clamping voltage of SMA6F100A-M3/H under a 10/1000 μs surge?
The SMA6F100A-M3/H has a maximum clamping voltage (VC) of 162 V when subjected to its rated peak pulse current under the standard 10/1000 μs waveform. This value is measured at the specified IPPM and defines the upper voltage limit imposed on the protected circuit during surge events. The SMA6F100A-M3/H maintains this clamping performance consistently across its qualified operating temperature range.
Is SMA6F100A-M3/H unidirectional or bidirectional?
SMA6F100A-M3/H is a unidirectional transient voltage suppressor, meaning it conducts only in reverse bias above its breakdown voltage and blocks current in forward bias. Its polarity is marked by a cathode band, and it must be oriented with cathode toward the protected line and anode to ground. The SMA6F100A-M3/H does not provide symmetrical clamping for AC or bipolar transients.
What package type does SMA6F100A-M3/H use, and what are its key mechanical attributes?
SMA6F100A-M3/H uses the SlimSMA (DO-221AC) surface-mount package, characterized by a maximum height of 0.95 mm, matte tin-plated leads, and compliance with MSL level 1 (260 °C peak reflow). Its footprint matches JEDEC-standardized dimensions for automated placement, and the cathode is identified by a visible band. The SMA6F100A-M3/H package supports high-density PCB layouts without compromising thermal or surge performance.
Does SMA6F100A-M3/H meet IEC 61000-4-2 ESD immunity requirements?
Yes, SMA6F100A-M3/H is rated for IEC 61000-4-2 level 4 ESD immunity: 8 kV contact discharge and 15 kV air discharge. This qualification is verified per standardized test conditions (150 pF capacitor, 330 Ω series resistor) and confirms robustness against common electrostatic events encountered during handling and field operation. The SMA6F100A-M3/H delivers this ESD protection without degrading its primary surge clamping function.
What is the maximum operating junction temperature for SMA6F100A-M3/H?
The maximum operating junction temperature (TJ max) for SMA6F100A-M3/H is 175 °C. This rating enables reliable operation in high-ambient environments such as enclosed industrial control cabinets or under-hood automotive locations. Thermal derating curves in the datasheet define safe power dissipation limits above 25 °C ambient, and the SMA6F100A-M3/H maintains full specification compliance up to this junction temperature limit.
