SMF60AT1

SMF60AT1 Application Field and Working Principle

SMF60AT1 is a type of TVS (Transient Voltage Suppression) diode that is commonly used in electronic devices such as computers, mobile phones, and other consumer applications. It is a low power, bidirectional, transient voltage surge protection (TVSS) device that is designed to protect against electrostatic discharge (ESD) surges and other types of voltage surges.

The device is built on principle of the “avalanche effect” which describes an effect that occurs when a voltage is applied to a diode in a way that the current rises exponentially. This avalanche effect can be described as the “snowballing” of electrons that happen when electric fields exceed a diode\'s breakdown voltage level. In this case, the SMF60AT1 has a very low capacitance of 0.3-12pF and a breakdown voltage range of 24-60v which help reduce the leakage current.

The SMF60AT1 is used mainly in communication systems, audio-video equipment, consumer electronics applications, automotive electronics, and power equipment. It can be used to protect sensitive components from overvoltage surges of 1500w peak power per line, and has a reverse energy absorption capability of 15A peak current per line. It is also widely used due to its ability to protect against electrical transients that are high frequency in nature and fast in duration.

Using this device also comes with a few caveats. It may not be the best choice for some applications, as it does not offer protection against long duration voltage transients. It is also important to select the proper voltage levels for each application so that the device can safely clamp in high voltages. It should also be noted that the device can heat up when in use, and as such, it is important to make sure it is mounted properly and in a way that allows for proper air flow so that heat can be dissipated.

In summary, the SMF60AT1 is a very useful device for protecting sensitive components from overvoltage and fast overcurrent transients. It has a very low capacitance and can handle a large current in a short duration. It is important to select the proper voltage level for each application so that the device can clamp in high voltage transients, and the device should be mounted in such a way that allows it to dissipate heat effectively.
