The MXLSMBG85CAE3 – A TVS - Diode

When it comes to electrical engineering, diode application fields and working principles are a very common topic of discussion. That is why we have decided to take a closer look at one specific diode – the MXLSMBG85CAE3 – and explain in detail its purpose and the way it functions.

The MXLSMBG85CAE3 is a transient voltage suppressor (TVS) diode, which is used to protect sensitive electronics from electrical transients and spikes in voltage. Such spikes are usually caused by power fluctuations or surges, short circuit conditions, and electromagnetic interference (EMI). The MXLSMBG85CAE3 is an integrated device, meaning that it is made up of several different components, which work together to provide voltage protection. These components include: two capacitors, two resistors, one Zener diode, and one transistor.

The MXLSMBG85CAE3 is designed to provide effective protection against ESD and EMI from both external and internal sources. It also helps protect the circuit from voltage overshoots during power cycles. The device comes in a small, two-pin dual-in-line package, which allows for easy installation and integration. It also has a wide operating temperature range of -55°C to 125°C, which makes it suitable for use under tough environmental conditions.

The MXLSMBG85CAE3 has an avalanche voltage of 32V, which provides a high level of protection against harmful transients. The device also features an integrated suppression network, which suppresses high frequency spikes to a low level. This ensures that the circuit is not damaged due to high frequency transients. The device also has a high temperature operating range of -55°C to 125°C, meaning that it can be used in environments with extreme temperatures.

The working principle of the MXLSMBG85CAE3 is based on voltage protection. When the voltage on the board exceeds the breakdown voltage of the diode, the device is triggered and starts to divert the extra voltage to the ground, thereby protecting the circuit from damage caused by the over voltage. This is done by the Zener diode, which acts like a voltage clamp, and the transistor, which acts as a switch to direct the current to the ground.

The MXLSMBG85CAE3 is a highly efficient, robust, and reliable protective device. Its wide operating temperature range and integrated suppression network make it ideal for a number of applications, including communications devices, sensors, cameras, consumer electronics, industrial machinery, and automotive systems. Moreover, its small size, low power consumption, and high avalanche voltage make it a great choice for cost-sensitive applications.

In conclusion, the MXLSMBG85CAE3 is an ideal diode for protecting sensitive electronics from voltage spikes and transients. Its wide operating temperature range and integrated suppression network make it suitable for use in a wide variety of applications. Moreover, its small size, low power consumption, and high avalanche voltage make it a great choice for cost-sensitive applications.
