Product details
Overview
SMA6F10A-M3/6B 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 10 V stand-off voltage (VWM), 15.7 V maximum clamping voltage (VC) at 38.2 A (10/1000 μs), 600 W peak pulse power, and IEC 61000-4-2 Level 4 ESD protection (15 kV air / 8 kV contact). It is used to protect MOSFETs, ICs, and sensor signal lines in industrial and telecom equipment.
For engineers reviewing the SMA6F10A-M3/6B datasheet, SMA6F10A-M3/6B pinout, SMA6F10A-M3/6B application, or SMA6F10A-M3/6B equivalent, key selection criteria include clamping performance under 10/1000 μs surge, thermal derating above 25 °C, unidirectional polarity, SlimSMA footprint compatibility, and MSL Level 1 reflow compliance.
Technical Context
This TVS diode operates as a voltage-clamped overvoltage protection device, triggered when reverse voltage exceeds its 11.1–12.3 V breakdown range (VBR at 1 mA). Its low dynamic resistance (0.089 Ω) ensures rapid response and tight clamping during transient events such as inductive load switching or lightning-induced surges.
It is rated for 175 °C maximum junction temperature and exhibits a voltage temperature coefficient of +7.8 × 10−4/°C, enabling predictable VBR drift across operating temperature. Thermal resistance junction-to-ambient is 120–150 °C/W on FR4 PCB, requiring layout-aware thermal management for sustained 8 W power dissipation at TM = 55 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6F10A-M3/6A | Identical electrical specs; differs only in tape-and-reel packaging (3500 pcs vs. 14000 pcs per reel) | No functional difference; selected when smaller reel quantity aligns with production batch size or inventory policy | Choose SMA6F10A-M3/6A for pilot runs or low-volume builds where 7" reel capacity suffices. |
| SMAJ10A | Same VWM/VC but higher RθJA (150 °C/W vs. 120–150 °C/W), lower PPPM (400 W vs. 600 W), DO-214AC (SMA) package | Larger footprint and lower surge rating limit use to less demanding applications like consumer USB ports | Select SMAJ10A only if SlimSMA's 0.95 mm height is not required and 400 W surge capability meets design margin. |

FAQ
What is the maximum clamping voltage of the SMA6F10A-M3/6B under a 10/1000 μs surge?
The SMA6F10A-M3/6B has a maximum clamping voltage (VC) of 15.7 V when subjected to a 10/1000 μs surge waveform at its rated peak pulse current of 38.2 A. This value is measured per JEDEC standards and ensures downstream circuitry remains within safe operating limits. The SMA6F10A-M3/6B achieves this with a low dynamic resistance of 0.089 Ω, minimizing voltage overshoot during fast transients.
Is the SMA6F10A-M3/6B suitable for bidirectional signal line protection?
No, the SMA6F10A-M3/6B is a unidirectional TVS diode and must not be used on AC-coupled or bidirectional data lines without external biasing. Its cathode-band marking and asymmetric IV curve provide clamping only in reverse bias. For bidirectional protection, a dedicated bidirectional part such as SMA6F10CA or dual-diode configurations are required. The SMA6F10A-M3/6B is intended for DC rails and unidirectional signal paths like sensor outputs or power inputs.
What is the thermal resistance of the SMA6F10A-M3/6B on a standard FR4 PCB?
The SMA6F10A-M3/6B has a typical junction-to-ambient thermal resistance (RθJA) of 120–150 °C/W when mounted on a standard FR4 PCB with 2 oz. copper and the recommended footprint. This value assumes no additional heatsinking and governs power derating above 25 °C ambient-e.g., its 8 W power dissipation rating applies only at TM = 55 °C. The SMA6F10A-M3/6B's SlimSMA package contributes to this moderate thermal impedance despite its low profile.
Does the SMA6F10A-M3/6B meet lead-free reflow requirements?
Yes, the SMA6F10A-M3/6B is halogen-free, RoHS-compliant, and qualified for lead-free reflow with a maximum peak temperature of 260 °C per J-STD-020, meeting MSL Level 1 moisture sensitivity classification. Its matte tin-plated terminals comply with J-STD-002 and JESD22-B102 solderability standards, and the M3 suffix confirms passing JESD201 Class 2 whisker testing-ensuring long-term interconnect reliability in automated assembly. The SMA6F10A-M3/6B is fully compatible with standard Pb-free reflow profiles.
How does the voltage temperature coefficient affect the SMA6F10A-M3/6B's breakdown voltage?
The SMA6F10A-M3/6B has a positive voltage temperature coefficient (αT) of +7.8 × 10−4/°C, meaning its breakdown voltage (VBR) increases linearly with junction temperature. At 100 °C, VBR rises by approximately 5.9% over its 25 °C value (11.1–12.3 V), resulting in ~11.7–12.9 V. This behavior ensures stable clamping margin across industrial temperature ranges and is accounted for using the formula VBR at TJ = VBR at 25 °C × (1 + αT × (TJ − 25)). The SMA6F10A-M3/6B's coefficient is tightly controlled for predictable performance in thermally dynamic environments.
