SMF14A-E3-18

Transient Voltage Suppression (TVS) diodes are specialized devices designed to protect electrical components and systems from surge events caused by lightning, power line transients, and other types of electrostatic discharges. The SMF14A-E3-18 is a unidirectional TVS that is designed for a variety of power spike protection applications. This diode can provide excellent protection against high-voltage transients that may otherwise damage sensitive components in a system.

The SMF14A-E3-18 has two terminals, an anode and a cathode. It works by dissipating the surge current by providing a shunt path from anode to cathode. This operation limits the voltage at the output to the breakdown voltage of the device. The diode is capable of handling up to 14 Amps of continuous current and is designed to provide surge ratings of up to 18 volts.

The SMF14A-E3-18 is primarily used in applications that require protection from high-voltage transients that are caused by power surges or electrostatic discharges. It is often used to protect power converters, DC-DC converters, Ethernet systems, Ethernet cables, wireless communication systems and other electronic devices.

The diode is designed to be placed between a power source and is connected in parallel with the load that needs protection. When a high-voltage transients occurs, the SMF14A-E3-18 will act as a short circuit to provide a shunt path from the anode to the cathode. This creates a low-impedance path that allows the surge current to be dissipated, thus preventing damage to the protected device.

The device is also designed to protect against reverse-polarity protection, which allows the device to operate normally during negative voltage transients. It also features the added protection of ESD protection, which helps protect against ESD events of up to 15kV.

The SMF14A-E3-18 is a unidirectional TVS that can provide excellent protection against overvoltage events in a variety of power spike protection applications. It is designed to be placed between a power source and is connected in parallel with the load that needs protection, thus providing a low-impedance path that can dissipate surge current and limit voltage at the output to the device’s breakdown voltage. The diode is also designed to provide reverse-polarity and ESD protection, making it able to handle even the toughest surge events.
