TVS - Diodes, also known as Transient Voltage Suppressors, comprise a range of fast-acting, low-impedance surge absorbent devices that use an electrical breakdown or an avalanche breakdown that occurs when the current through the diode exceeds a certain value. The 1KSMB91A is one of these devices, and has many applications due to its impressive power handling capabilities.

First of all, let’s take a look at the 1KSMB91A application field and working principle. The 1KSMB91A TVS diode has been designed to absorb and dissipate high-level lightning, static discharge (ESD), and electrical transients due to other sources of electrical noise when used in automotive, industrial, and consumer electronics. Its extremely fast response time allows it to protect devices from both hazardous high-voltage transients as well as low-energy ESD events. It can also be used to reduce power levels in some applications, and to control noise levels in others.

The 1KSMB91A devices are capable of providing a transient protection to components and systems against electrostatic discharge (ESD). This is made possible by its reliable integrated ESDZ7.4 protection. The 1KSMB91A offers great flexibility for usage as it is available in various configurations, including single, dual, and four-channel devices. This makes it possible to use the 1KSMB91A in a wide variety of applications, from automotive to consumer electronics, in order to protect systems from ESD or lightning-induced damage.

The breakdown voltage of the 1KSMB91A is typically rated at 7.5V, and it is able to provide a holding current up to 15A in single-shot or repetitive pulses, making it an efficient device for protection against high voltage and current transients.

In terms of performance, the 1KSMB91A has a very low leakage current, fast response time, wide-range robustness, and low clamping voltage over temperature. It also offers excellent robustness to the effects of lightning transients, low-energy ESD, and voltage transients when used correctly. It has a high peak power rating and can withstand high peak surge currents, making it suitable for use in harsh environments.

The 1KSMB91A is a versatile TVS diode that can be used for ESD protection, lightning protection, and power controlling. It can also be used as a voltage regulator to reduce power levels in some applications. Its reliability, robustness, and superior performance make it an excellent choice for a wide variety of applications in both automotive and consumer electronics.
