TVS (Transient Voltage Suppressor) diodes are widely used for protection from voltage spikes in circuit designs. The MXSMBJSAC18E3 TVS diode from Micross Components is a popular choice of TVS diode which has many applications. This article will look at the applications of the MXSMBJSAC18E3 and how it works to protect against voltage spikes.

Applications of the MXSMBJSAC18E3

The MXSMBJSAC18E3 is a bi-directional TVS diode, meaning it can adequately protect against both positive and negative voltage spikes. This makes it suitable for a variety of different applications. These include ESD (electrostatic discharge) protection, over-voltage protection, and EMI (electromagnetic interference) suppression. The MXSMBJSAC18E3 is also a popular choice for industrial and automotive applications where high levels of circuit protection are often necessary.

The MXSMBJSAC18E3 comes in an easy-to-use SOD-123 package. The package is rated to 8A peak pulse current, which makes it suitable for many different applications. The diode can operate at temperature ranging from −40°C to +125°C, making it perfect for hot and cold climates. It has a low clamping voltage of 18.3V which helps to reduce the risk of circuit damage. The diode also has a built-in internal fail-safe feature which helps to protect circuits from over-voltage spikes.

Working Principle of the MXSMBJSAC18E3

The MXSMBJSAC18E3 is a unidirectional or bi-directional device which works to protect against over-voltage events. It can be used for both ESD protection and EMI protection. The device works in two stages; the first is the "breakdown" stage where the device begins to conduct. During this stage, the voltage across the device increases as current passes through it. When the breakdown voltage is reached, it enters the second stage, the "clamping" stage. During this stage, the voltage on the device is clamped to a fixed level, the "clamping voltage" of 18.3V for the MXSMBJSAC18E3. The device then absorbs any additional energy, dissipating it in the form of heat. The fail-safe feature ensures that the voltage never goes above the clamping voltage, thereby protecting the circuit from over-voltage events.

The MXSMBJSAC18E3 is a reliable and cost-effective solution for many applications. It is easy to install and provides excellent protection against voltage spikes. It also has the added benefit of being bi-directional, so it can adequately protect against both positive and negative voltage spikes.

Conclusion

The MXSMBJSAC18E3 is a popular choice of TVS diode for many different applications. It is an easy-to-use device with a low clamping voltage of 18.3V which helps to reduce the risk of circuit damage. The diode is also bi-directional, so it can adequately protect against both positive and negative voltage spikes. It has a built-in internal fail-safe feature which helps to protect circuits from over-voltage events. Overall, the MXSMBJSAC18E3 is an ideal choice for many different applications where protection from voltage spikes is necessary.
