TVS (transient voltage suppressors) diodes are special devices that are designed to provide protection from high-energy pulses, like those that are created from electrostatic discharge (ESD) or lightning strikes. The 1KSMB20 is a TVS diode that is designed to provide a specific level of protection for sensitive electronic components. It is rated to protect against 20KV of voltage.

The 1KSMB20 is designed to be installed in an optimized layout that allows for the highest level of protection. It utilizes a symmetrical clamping action that helps to minimize the overshoot and ringing that can often occur with other TVS diode designs. This means that it can provide effective protection against ESD pulses and lightning surges.

The working principle of the 1KSMB20 TVS diode can be explained by looking at how it functions when exposed to a voltage spike. When it is exposed to a voltage spike, the 1KSMB20 will start to conduct, and the capacitance between the cathode and anode will start to charge. This will cause the diode to clamp the voltage at rated value of 20KV. As it clamps the overvoltage, a large current is diverted away from the protected device. This limits the voltage that goes through the device, and allows it to remain functioning properly.

The 1KSMB20 TVS diode is typically used in automotive and consumer electronics applications that require reliable protection from ESD and lightning. It is designed to ensure that any transient voltage spikes are clamped to a safe level before they can reach the sensitive electronic components. It can be used in a variety of configurations, including clamping over single- or multi-line configurations. This makes it a very versatile option for providing reliable protection for sensitive electronics.

The 1KSMB20 TVS diode is a tried and tested technology that is used to provide reliable protection for sensitive electronic components in a variety of applications. It utilizes a symmetrical clamping action to ensure that it provides the highest level of protection against ESD pulses and lightning surges. It is rated to protect against 20KV of voltage, and is designed for use in automotive and consumer electronics applications. Thanks to its versatile design, it can be used in a variety of configurations to ensure that it is always providing optimal protection for sensitive components.
