TVS - Diodes are widely used for overvoltage protection in many applications today. SMF60A RVG (Reverse Voltage Guard) diode is one of the most popular TVS-diodes in the market. It is designed for automotive applications and provides excellent protection against transients.

This diode is effective in the protection of a wide variety of high frequency signal lines. The low capacitance and leakage current make it an ideal choice for use in a variety of automotive safety and entertainment systems. It also works well for reverse protection of infotainment systems such as audio lines, video lines, and control lines.

The SMF60A RVG has a total of three terminals. The anode terminal is designed to be connected to the positive side of the power voltage. The cathode terminal is the negative side of the power voltage. The central lead is an optional link between the cathode and the anode.

The working principle of the SMF60A RVG is fairly simple. When connected to the power lines, the anode and cathode terminals are kept at the same potential. When a transient occurs, the potential difference between the terminals increases. This voltage increase triggers the reverse voltage guard to disconnect the power voltage line until the voltage reduces to its nominal level.

The reverse voltage guard is designed to be able to absorb high levels of energy when transients occur. It will conduct current away from the power line until the transient has been removed. This helps to prevent damage to the connected components due to overvoltage conditions.

The SMF60A RVG also offers excellent protection against static discharge and high speed transients. It has a clamping voltage of over 2 kV and can dissipate up to 65A of energy in the event of a transient. This makes it suitable for protection against most short duration transient threats.

The SMF60A RVG is commonly used in automotive systems and applications such as infotainment systems, airbags, seatbelts, power windows, and control systems. It provides fast response time, excellent ESD and EFT protection, and low capacitance for high-frequency signal protection. It is also RoHS compliant, making it a great choice for automotive applications.
