Product details
Overview
SMA6F5.0A-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 5.0 V signal or power lines. It delivers 600 W peak pulse power (10/1000 μs), clamps to 9.2 V at 375 A, and exhibits 5.0 V stand-off voltage with only 5 μA leakage at rated voltage - ideal for protecting USB interfaces, sensor I/O, and microcontroller GPIOs against ESD and inductive switching surges.
For engineers reviewing the SMA6F5.0A-M3/6A datasheet, SMA6F5.0A-M3/6A pinout, SMA6F5.0A-M3/6A application, or SMA6F5.0A-M3/6A equivalent, key selection criteria include its 9.2 V clamping voltage at 375 A, 5.0 V stand-off rating, unidirectional polarity, SlimSMA footprint compatibility, and IEC 61000-4-2 level 4 ESD immunity (15 kV air / 8 kV contact).
Technical Context
This TVS diode operates as a fast-acting, avalanche-based voltage clamp triggered by transient overvoltage events exceeding its 6.4–7.07 V breakdown range. Its low dynamic resistance (68 Ω) ensures minimal voltage overshoot during surge conduction, while its 0.95 mm profile enables placement near IC inputs without compromising board space.
The device is optimized for automated SMT assembly, meets JESD201 class 2 whisker resistance, and is halogen-free, RoHS-compliant, and MSL level 1 rated (260 °C reflow). Its thermal resistance junction-to-ambient is 120–150 °C/W on FR4, supporting reliable operation up to 175 °C junction temperature.

FAQ
What is the maximum clamping voltage of the SMA6F5.0A-M3/6A under a 10/1000 μs surge?
The SMA6F5.0A-M3/6A clamps to 9.2 V at 375 A under a 10/1000 μs waveform, as specified in the Vishay datasheet revision 17-Sep-2021. This value is measured at peak pulse current and defines the upper voltage limit imposed on protected circuits during standardized surge events. The SMA6F5.0A-M3/6A maintains this clamping performance across its qualified operating temperature range.
Is the SMA6F5.0A-M3/6A suitable for bidirectional signal line protection?
No, the SMA6F5.0A-M3/6A is unidirectional only, as explicitly stated in the Vishay datasheet features section. It conducts surge current from cathode to anode during reverse overvoltage but does not protect against positive transients on the anode side. For bidirectional protection, a dedicated bidirectional TVS such as SMA6F5.0CA must be selected instead of the SMA6F5.0A-M3/6A.
What is the standoff voltage rating and leakage current of the SMA6F5.0A-M3/6A at 25 °C?
The SMA6F5.0A-M3/6A has a standoff voltage (VWM) of 5.0 V and a maximum reverse leakage current (ID) of 5 μA at that voltage and 25 °C, per the Electrical Characteristics table in the Vishay datasheet. This low leakage ensures minimal power loss and signal distortion in always-on 5 V monitoring circuits, confirming the SMA6F5.0A-M3/6A's suitability for battery-powered and low-quiescent-current applications.
Does the SMA6F5.0A-M3/6A meet industry-standard ESD immunity requirements?
Yes, the SMA6F5.0A-M3/6A is certified to IEC 61000-4-2 level 4 for electrostatic discharge immunity: 15 kV air discharge and 8 kV contact discharge. This qualification is documented in the Immunity to Static Electrical Discharge section of the Vishay datasheet and confirms the SMA6F5.0A-M3/6A's ability to protect downstream components without additional ESD circuitry in end-equipment compliance testing.
What package type and mounting specifications apply to the SMA6F5.0A-M3/6A?
The SMA6F5.0A-M3/6A uses the SlimSMA (DO-221AC) package - a surface-mount case with 0.95 mm typical height, matte tin-plated leads, and cathode identification via color band. It meets MSL level 1 per J-STD-020, supports 260 °C peak reflow, and is qualified for JESD201 class 2 whisker resistance. These attributes ensure the SMA6F5.0A-M3/6A is fully compatible with high-speed automated placement and lead-free reflow processes.
