Vishay General Semiconductor - Diodes Division SMA6F10A-M3/6A

Overview

SMA6F10A-M3/6A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SlimSMA (DO-221AC) package, designed for clamping voltage transients on power and signal lines. It features a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 15.7 V maximum clamping voltage (VC) at 38.2 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 SMA6F10A-M3/6A datasheet, SMA6F10A-M3/6A pinout, SMA6F10A-M3/6A application, or SMA6F10A-M3/6A equivalent, this device is selected for robust overvoltage protection in space-constrained consumer, industrial, and telecom systems where low-profile mounting and high surge current handling are critical.

Technical Context

This TVS diode operates as a unidirectional Zener-clamp device, triggered when reverse voltage exceeds its breakdown threshold (VBR). Its dynamic resistance (RD = 0.089 Ω) ensures low clamping voltage rise under surge current, while its thermal design supports junction temperatures up to +175 °C and derating above 25 °C ambient.

The SMA6F10A-M3/6A uses a silicon planar junction structure with matte tin-plated leads compliant with J-STD-002 and JESD22-B102 solderability standards. Its SlimSMA (DO-221AC) package meets UL 94 V-0 flammability rating and MSL level 1 per J-STD-020, with peak reflow temperature of 260 °C.

FAQ

What is the maximum clamping voltage of the SMA6F10A-M3/6A under a 10/1000 μs surge?

The SMA6F10A-M3/6A has a maximum clamping voltage (VC) of 15.7 V when subjected to a 10/1000 μs waveform at 38.2 A peak pulse current. This value is measured per standard test conditions in the Vishay datasheet (Document Number: 89458, Rev. 17-Sep-2021) and reflects worst-case clamping performance at rated surge level. The SMA6F10A-M3/6A maintains this clamping performance across its specified operating temperature range.

Is the SMA6F10A-M3/6A unidirectional or bidirectional?

The SMA6F10A-M3/6A is a unidirectional TVS diode, as explicitly stated in the Vishay datasheet under FEATURES and PRIMARY CHARACTERISTICS. It conducts only in reverse bias above VBR and blocks forward current like a standard diode-making it suitable for DC-biased lines such as power rails and single-ended signal paths. The SMA6F10A-M3/6A does not provide symmetrical clamping for AC signals.

What is the package type and physical size of the SMA6F10A-M3/6A?

The SMA6F10A-M3/6A uses the SlimSMA (DO-221AC) package, measuring 4.15–4.35 mm in length, 2.50–2.70 mm in width, and 0.95 mm typical height. Its low-profile design enables placement in tight spaces, and its cathode is marked by a visible color band. The SMA6F10A-M3/6A complies with JEDEC MO-290 and is compatible with standard SMT pick-and-place equipment.

Does the SMA6F10A-M3/6A meet automotive AEC-Q200 requirements?

No, the SMA6F10A-M3/6A is not AEC-Q200 qualified. It is rated for industrial-grade operation (−55 °C to +175 °C junction temperature) and meets MSL level 1 and IEC 61000-4-2 level 4, but Vishay does not list AEC-Q200 qualification for this part in its official documentation. For automotive applications, engineers should consider Vishay's AEC-Q200-qualified TVS families such as the AUTOMOTIVE SMA6F series variants explicitly marked "AEC-Q200".

What is the leakage current specification for the SMA6F10A-M3/6A at its stand-off voltage?

The SMA6F10A-M3/6A exhibits a maximum reverse leakage current (ID) of 1.0 μA at its 10 V stand-off voltage (VWM), tested at TA = 25 °C per the Vishay datasheet. This low leakage ensures minimal power loss in always-on circuits and preserves battery life in portable applications. The SMA6F10A-M3/6A maintains this spec across its full operating temperature range, with leakage increasing predictably per device physics but remaining well below 10 μA at +85 °C.
