Description

1KSMB12CAHM4G is a unidirectional, low capacitance transient voltage suppressor (TVS) with dual series connection for very high peak pulse current absorption and voltage clamping performance. It features a high surge capability and low clamping ratio and has validations for applications including automotive, telecommunication and industrial electronics.

Application Field

The 1KSMB12CAHM4G has a wide range of applications due to its protection capabilities against high voltage spikes . Such applications include automotive electronics, telecommunications devices, computers, peripherals, consumer electronics and industrial application. It provides protection against voltage transients for all kinds of loads, power grids and circuits that are vulnerable to damage from overvoltage.

Working Principle

The 1KSMB12CAHM4G is composed of two series-connected diodes connected together to form a single junction. This junction is designed to operate in a manner such that when an overvoltage is applied to the device, a current starts to flow and the voltage is pulled down toward the breakdown voltage level. This breakdown voltage level is calculated after the junction is formed by the diodes - the characteristics of the individual diodes such as the built-in voltage, the capacitance and the junction temperature are taken into consideration in this calculation. The current continues to flow until the excess voltage is dissipated, and as the current passes through the junction, a negative charge is created. This negative charge creates a barrier between the two series connected diodes, thus preventing any further current from passing through the junction. This charging is what makes the 1KSMB12CAHM4G effective against high voltage transients.

Benefits

The 1KSMB12CAHM4G is an impressive device with a high surge handling capability and a low clamping ratio, making it an ideal choice for protecting sensitive electronics against overvoltage.
