Additionally, it can be used as a secondary protection device for power supplies, to prevent damage from ESD and other high voltage transients.

Working Principle

The SMF30A-M3-18 works on the principle of breakdown voltage. It is constructed from a section of a reverse bias PN junction diode. When the applied voltage exceeds the breakdown voltage, the current flows through the diode. This current is then limited by the device, and the voltage is clamped to the breakdown voltage, thus protecting the circuit from overvoltage surges.

The SMF30A-M3-18 is a highly versatile device, and is an ideal solution for applications that need protection from high voltage transients. Its low capacitance and high speed switching capability make it suitable for use in high frequency circuits, and its low thermal resistance makes it suitable for applications which require high thermal stability.
