TVS - Diodes

A TVS (Transient Voltage Suppressor), also known as a surge suppressor, is a semiconductor device that is designed to protect electrical equipment from voltage spikes(). It is a two-terminal device that is designed to protect multiple lines and the equipment connected to those lines. The TVS is usually packaged in a small, hermetically sealed() package that is designed for surface mounting.1KSMB91A M4G is one of the most popular TVS-diodes, manufactured by Littelfuse. The 1KSMB91A has a peak pulse power of 1000 watts and a standoff voltage of 91 volts. It also includes a range of features designed to ensure reliable protection against transients and overvoltage.1KSMB91A M4G is most commonly used in applications such as telecomms, automotive, industrial, and consumer electronics. Its applications include wide range of devices like switches, power supplies, routers, servos, and mains box connections.The working principle of the 1KSMB91A M4G is relatively simple. It is a two-terminal device, with one terminal connected to the power source, and the other terminal connected to ground. When a voltage above the rated standoff voltage is applied to the terminal, the device conducts the extra voltage to ground, preventing it from reaching the connected equipment or circuits. If the applied voltage is below the rated standoff voltage, the device acts as an insulator, blocking the current.The 1KSMB91A M4G is designed to provide protection in both AC and DC circuits. It can be used to protect multiple line circuits such as RS-232 and RS-485 cables, as well as to protect single point signal circuits such as USB and HDMI.When selecting a TVS-diode for a specific application, it is important to consider the surge current rating, the standoff voltage, the peak pulse power and the surge response time. It is also important to select a device that is compatible with the environment in which it is to be used, and to ensure that the device is able to handle the required peak pulse power rating.The 1KSMB91A M4G is a popular, reliable, and cost effective choice for surge and transient voltage protection in a wide range of applications. It is designed to provide reliable protection in both DC and AC circuits, and is available in a variety of packages and configurations.
