TVS (Transient Voltage Suppressor) diodes are an essential component of modern electronic systems. They are necessary to protect the system from unexpected high voltages arriving from external sources such as electrostatic discharge (ESD) or lightning strikes. The 1KSMB24 is a double-diode, unidirectional device used for transient overvoltage protection, with an ideal breakdown voltage of 24V.

The 1KSMB24 is a surf-mountable device with zero recovery time and ultra-fast response time. It offers good clamping performance and low clamping voltage, and its small size allows it to fit in the most sensitive of applications. This device is rated for use in the automotive industry, as well as telecommunications, consumer and industrial applications.

The 1KSMB24 has two main components - a cathode and an anode. The anode is connected to the positive supply and the cathode is connected to the ground. When a high voltage transient is encountered, the anode gets connected to the cathode, creating an electrical path and thus clamping the overvoltage. The waveform of the high voltage transient is limited in magnitude and duration, preventing damage to sensitive components. The device is very efficient in reducing the unwanted voltage in a small area.

The working principle of the 1KSMB24 is based on avalanche breakdown. When the device is in an off state, its internal voltage is slightly lower than the applied voltage. When the external voltage exceeds its breakdown voltage, an avalanche of electrons starts flowing through the device, creating an additional positive conductive path. This leads to an increase in voltage and current, limiting the application of the excess voltage.

This device has an excellent thermal stability and robustness, which allows it to withstand high and reverse voltage loads. The 1KSMB24 is RoHS compliant and does not contain any hazardous materials, making it a safe choice for use in many applications. Furthermore, it offers a low capacitance and thus can be used in high frequency applications with no attenuation.

The 1KSMB24 is an incredibly useful component for transient overvoltage protection. Its high efficiency, low capacitance, and thermal stability make it a great choice for a variety of applications. It is perfect for use in sensitive electronic systems featuring communication, automotive, consumer, and industrial applications. Thus, the 1KSMB24 can be considered a reliable and efficient choice for overvoltage protection.
