SMF48AT1 is a Transient Voltage Suppressor (TVS) diode. It is a unidirectional doide designed to protect sensitive electronic components from voltage spikes. The diode is designed to limit any voltage above its specified breakdown voltage. In addition to its voltage protection capabilities, the diode is also designed to prevent thermal runaways and reverse voltage transients.The SMF48AT1 is a member of the SMF Series mounted in an SOT523 package. This package is extremely compact, allowing it to be integrated into the tightest of spaces. It has the capability to handle an operating junction temperature of 175°C, making it suitable for automotive and industrial applications. The SMF series is a fast response, voltage dependent device, allowing it to quickly respond to transient events. In addition, the device also features low capacitance, which reduces the degradation of signal performance.The SMF48AT1 has a reverse breakdown voltage of 48V and a reverse clamping voltage of 62V. This means that the device will activate when a voltage greater than 48V is applied, clamping any transient voltage beyond units 62V to ground. It has an operating temperature range of -55°C to 175°C and a storage temperature range of -55°C to 175°C. The diode has a maximum forward voltage of 1.2V and a maximum peak pulse current rating of 24A. It has a maximum leakage current rating of 200µA and a maximum reverse current of 2µA. The device also has a thermal resistance of 5K/W and a power dissipation rating of 1W.The SMF48AT1 has a wide range of applications. One of the most common applications of the device is in automotive circuits. The device is used in automotive systems to protect sensitive electronic components from electrical transients due to load switching or voltage spikes. The device is also commonly used in industrial power systems, providing protection against large voltage transients. In addition, the device is used in consumer electronics such as computers, mobile phones, and LCD TVs, where it provides a reliable protection from voltage transients.To summarize, the SMF48AT1 is a unidirectional TVS diode designed to protect sensitive electronic components from electrical transients. It has a reverse breakdown voltage of 48V and a reverse clamping voltage of 62V. It has an operating temperature range of -55°C to 175°C and a storage temperature range of -55°C to 175°C. The device has a maximum forward voltage of 1.2V and a maximum peak pulse current rating of 24A. It is used commonly in automotive, industrial, and consumer electronics applications.
