SMBJ440A-H is a member of the transient voltage suppressor (TVS) diode product lines. This type of diode works as a voltage protector to limit other components’ exposure to damaging voltage levels. It is engineered to respond quickly to fast rising transients, and to limit the voltage that gets to sensitive circuit components. This type of diode also works well in pulse power applications.

The SMBJ440A-H diode is a unidirectional suppressive device that is designed to protect low power and low voltage elements from transient voltage events. The diode is a glass-body package that consists of a cathode and an anode. It is made from silicon and the junction semiconductor is configured as a reverse-biased zener. The diode uses avalanche breakdown to suppress high voltage transients.

SMBJ440A-H has many application fields. It is used in cellular phones, TV sets, computers, and other electronic components in consumer products. It can be used in the telecommunications industry for its protection against lightning or surges and to protect equipment from higher than normal voltage levels. It is also useful in applications where lightning protection is required to protect against over-voltage levels, such as automotive applications. Furthermore, this type of diode has earned a well-deserved reputation in industrial applications to protect energizing circuits from over-voltage transients.

The working principle of SMBJ440A-H is simple. When the voltage input exceeds a certain level, the diode switches into its avalanche breakdown region and clips the input waveforms. This limits the output voltage, protecting any sensitive elements downstream from the transient voltage. This type of diode is particularly suitable for protection from lightning hits, electrostatic discharge, and other surges caused by high-frequency electrical noise.

The SMBJ440A-H diode is one of the most reliable and economical TVS diodes available. It is simultaneously simple and effective, requiring minimal design effort to implement while providing effective protection against various power transients. This type of diode is also a great choice for applications that require low power dissipation and low voltage. The device\'s rugged design and absolute quality makes it a versatile and dependable TVS diode that can protect a variety of electronic components for a range of low power and low voltage applications.
