Product details
Overview
SMA6F6.0A-M3/6A 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 6.0 V stand-off voltage (VWM), 6.7–7.41 V breakdown voltage (VBR) at 10 mA, 9.5 V maximum clamping voltage (VC) at 600 A (10/1000 μs), 600 W peak pulse power rating, and ESD immunity per IEC 61000-4-2 level 4 (15 kV air / 8 kV contact).
For engineers reviewing the SMA6F6.0A-M3/6A datasheet, SMA6F6.0A-M3/6A pinout, SMA6F6.0A-M3/6A application, or SMA6F6.0A-M3/6A equivalent, this device is selected for robust overvoltage protection in space-constrained consumer, industrial, and telecom power rails and sensor interfaces where low-profile mounting and high surge current handling are required.
Technical Context
The SMA6F6.0A-M3/6A operates as a Zener-based unidirectional TVS diode with sharp avalanche breakdown behavior, enabling fast response to transient events. Its clamping performance is defined by dynamic resistance (RD = 63.2 Ω max) and temperature coefficient (αT = 0.022 × 10⁻⁴/°C), ensuring stable VBR across operating junction temperatures from –55 °C to +175 °C.
It delivers 600 W peak pulse power under 10/1000 μs waveform and 4 kW under 8/20 μs waveform, with thermal resistance junction-to-ambient (RθJA) rated at 120–150 °C/W on FR4 PCB. The device meets MSL Level 1 per J-STD-020 and supports reflow up to 260 °C peak.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6F6.0A-M3/6B | Same electrical specs; differs only in tape-and-reel packaging (14,000 pcs vs. 3,500 pcs per reel). | No functional difference; selected for high-volume automated assembly requiring larger reels. | Choose SMA6F6.0A-M3/6B when optimizing for pick-and-place efficiency in mass production. |
| SMAJ6.0A-M3/61 | Higher RθJA (150 °C/W vs. 120–150 °C/W), same VWM/VBR/VC, but rated for 400 W (10/1000 μs) instead of 600 W. | Limited to lower-energy surge environments; not suitable for IEC 61000-4-5 level 3/4 testing. | Select SMAJ6.0A-M3/61 only if system-level surge requirements are ≤400 W and cost sensitivity outweighs headroom needs. |
Compared with SMA6F6.0A-M3/6A, SMA6F6.0A-M3/6B offers identical protection performance with higher reel quantity, while SMAJ6.0A-M3/61 provides reduced surge margin (400 W vs. 600 W) and higher thermal resistance-making SMA6F6.0A-M3/6A the preferred choice for demanding industrial and telecom applications requiring full 600 W rating and flexible reel sizing.

FAQ
What is the clamping voltage of the SMA6F6.0A-M3/6A under a 600 A, 10/1000 μs surge?
The SMA6F6.0A-M3/6A exhibits a maximum clamping voltage (VC) of 9.5 V when subjected to a 600 A peak pulse with 10/1000 μs waveform. This value is measured at TA = 25 °C and represents the upper bound of voltage imposed on the protected circuit during such a transient event, ensuring downstream components remain within safe operating limits.
Is the SMA6F6.0A-M3/6A suitable for bidirectional transient protection?
No, the SMA6F6.0A-M3/6A is explicitly a unidirectional TVS diode, as confirmed in the Vishay datasheet under FEATURES and PRIMARY CHARACTERISTICS. It conducts only in reverse breakdown mode and must be oriented with cathode toward the protected line; bidirectional protection requires a symmetric device like SMA6F6.0CA.
What is the maximum junction temperature rating for the SMA6F6.0A-M3/6A?
The SMA6F6.0A-M3/6A has a maximum operating junction temperature (TJ max.) of +175 °C, as specified in the PRIMARY CHARACTERISTICS table. This enables reliable operation in high-ambient environments such as enclosed industrial enclosures or near heat-generating components like motor drivers.
Does the SMA6F6.0A-M3/6A meet RoHS and halogen-free requirements?
Yes, the SMA6F6.0A-M3/6A carries the "M3" suffix, which denotes halogen-free, RoHS-compliant, and industrial-grade construction per Vishay's ordering information and mechanical data sections. Its molding compound also meets UL 94 V-0 flammability rating.
How does the leakage current of the SMA6F6.0A-M3/6A compare at its 6.0 V stand-off voltage?
At VWM = 6.0 V and TA = 25 °C, the SMA6F6.0A-M3/6A specifies a maximum reverse leakage current (ID) of 600 μA. This low leakage ensures minimal power loss and avoids interference with sensitive analog or low-power digital circuits connected to the protected node.
