A TVS diode, or transient voltage suppressor diode, is a specialized form of semiconductor protection device designed to protect sensitive electronics from voltage spikes. The MMBZ18VAL-7 is a unidirectional type of TVS diode that is commonly used in applications such as telecommunications, consumer electronics, medical devices, automotive, and automotive. In this article, the focus will be on the MMBZ18VAL-7 and its application fields and working principles.
Application Field
The MMBZ18VAL-7 is a unidirectional TVS diode that is often used to protect external electronics circuits from electrostatic discharge (ESD) events. It is mainly used in low-voltage applications. It can also be used as a bidirectional device by connecting two diodes in parallel (back-to-back), providing dual-side protection from ESD events. This type of diode is also often used in automotive systems, such as antilock braking systems, instrument clusters, and sensor controls. Additionally, it can be used in consumer electronics, telecommunications, and medical electronics.
Working Principle
How does the MMBZ18VAL-7 work, you might ask? The working principle of this type of diode is simple. When a voltage spike (above the breakdown voltage) occurs, the diode becomes forward-biased, allowing current to flow through the diode. This current is clamped down and dissipated by the diode instead of passing through the electronics circuit, thus protecting it from damage. The diode will then recover to a non-conductive state once the surge has passed.
The MMBZ18VAL-7 is generally designed to absorb a certain amount of energy during a voltage spike (its maximum power dissipation is given in the datasheet). Once that energy has been consumed, the diode will enter an off-state, thus allowing the voltage to return to its normal value. This process is known as "clamping" and is the main job of the TVS diode.
Conclusion
In conclusion, the MMBZ18VAL-7 is a unidirectional TVS diode that is commonly used in applications ranging from automotive to consumer electronics and telecommunications. Its main job is to protect electronics from voltage spikes by clamping down and dissipating the surges. It can be used as either a unidirectional or bidirectional device, depending on the application. The working principle of the diode is simple and reliable, providing a safe and reliable protection for your electronic circuitry.
