TVS (Transient Voltage Suppressors) diodes are used in circuit protection applications to provide a clamping action against surges and spikes in voltage that surpass the working range of the semiconductor. The popular SMA6F17A-M3/6B TVS diode is used as a strike and surge protection device, designed for dual-line applications with both common-mode and differential-mode protection. In this article, we discuss its application field and working principle.

Application Field of SMA6F17A-M3/6B

The SMA6F17A-M3/6B is a dual-line TVS diode designed for use in RS-232 serial communication systems. It is ideal for securing the data lines of automotive applications such as back up cameras, audio systems, navigation systems, and instrumentation systems. It was designed to provide protection against ESD (electro-static discharge) and other over-voltage transients. It is also suitable for use in Ethernet systems.

This diode is designed to protect against 7-volt/5-A surges on each line with a total peak pulse power dissipation of 520 W. It offers superior performance in terms of capacitance, ESD clamping voltage, and frequency response. The SMA6F17A-M3/6B is able to suppress AC, DC, and pulse-type currents efficiently. It also features excellent clamping voltage and low capacitance.

Working Principle of SMA6F17A-M3/6B

The SMA6F17A-M3/6B is an integrated, dual line TVS diode. It consists of two protection circuits in a single package. One line is for common mode and the other for differential mode operation. Each line is protected by a metal oxide varistor that clamps the surge voltage. This protects the connected devices from harmful over-voltage transients.

When an over-voltage transient occurs, the transient voltage is coupled to a point on the varistor. This produces an electric field or an electrostatic voltage at the junction. The resulting current flow through the junction generates a voltage drop that clamps the transient voltage to a safe level. This prevents damage to the connected components.

The SMA6F17A-M3/6B is designed with dual-line technology to provide fast and reliable surge protection. The two protection circuits in the device provide optimal protection for RS-232 lines, as well as Ethernet systems. The fast response time of this device prevents damage to connected components from over-voltage transients.
