MSMBJ18CAE3

The MSMBJ18CAE3 TVS - Diodes is designed to protect sensitive electronic components from damaging voltage transients produced by electrostatic discharge (ESD), electrical fast transients, and lightning strikes. This surge protection device has been designed for use in applications such as networking, telecom, servers, consumer electronics, etc. The device consists of two primary sections: an automotive-grade avalanche diode and a low-voltage zener diode array.

Application Field

The MSMBJ18CAE3 is an automotive-grade TVS - Diodes device, meaning it is designed specifically for automotive applications. This product is ideal for protecting automotive components from ESD, electrical fast transients, and lightning strikes. The device also has EMI filtering capability, meaning it can reduce the amount of undesirable noise added to electronic signals due to external electrical interference.

The MSMBJ18CAE3 device is designed to protect automotive and electronic components from potentially damaging transients. This device provides protection from transients up to 35V (Vp) peak, 100A peak pulse current, and a 500W pulse power rating. The device has a wide operating temperature range (-55℃ to +175℃) and is suitable for automotive and industrial applications.

Working Principle

The MSMBJ18CAE3 is an automotive-grade TVS - Diodes device. It works by suppressing transients in two stages. The first stage is provided by the avalanche diode. This diode works by automatically switching to a low resistance state when it is exposed to a voltage above its breakdown voltage (Vbr). This low resistance state allows the current to pass through the diode, thereby suppressing transient voltages.

The second stage of transient protection is provided by the low-voltage zener diode array. This array works by automatically switching to a low resistance state when it is exposed to a voltage above its breakdown voltage (Vbr). The low resistance state enables the current to pass through the array, thereby suppressing transient voltages. Both stages of the MSMBJ18CAE3 device work together to protect sensitive components from potentially damaging transient voltages.

The MSMBJ18CAE3 is a cost-effective and reliable TVS - Diodes solution for automotive applications. It is designed to protect sensitive components from ESD, electrical fast transients, and lightning strikes. In addition, the device has EMI filtering capability which helps reduce external electrical noise interference. The device operates within a wide temperature range, making it suitable for almost any automotive or industrial application.
