M1.5KE120AE3 is a type of Transient Voltage Suppressor (TVS) diode. It is most commonly used to help protect against transient voltages, such as those produced by electrostatic discharge (ESD).

Application Field

The M1.5KE120AE3 TVS diode is mostly used in the fields of circuits, batteries, computers, and power supplies. Generally, it is recommended to use it when designing circuits that come into contact with static electricity, or in circuits where there is a risk of voltage spikes or other voltage transients. This TVS diode can also be used in applications which could store very high levels of energy, such as photovoltaic systems which use lead acid batteries. Additionally, the M1.5KE120AE3 TVS diode can be used in 5V circuit protection, automotive circuits, or other circuits that experience a large number of transient voltages.

Working Principle

The M1.5KE120AE3 TVS diode works by providing a fast current clamping path during an over-voltage situation. It does this by applying a reverse voltage across itself due to its internal PN junction. This in turn limits the amount of current that can flow through it. When an over-voltage situation is detected, the reverse voltage will increase and will cause a rapid current flow to surge through the TVS diode. This will then effectively limit the amount of voltage that is discharged and protect the underlying components.

The M1.5KE120AE3 TVS diode comes with a variety of features that make it an excellent choice for many applications. For example, it offers an industry-leading low clamp voltage of 12V, along with a standoff voltage of 5V and a breakdown voltage of 7V. Additionally, it has a peak pulse power rating of 400W and is capable of handling up to 30A of surge current. It also comes with a fast response time of less than 1ns, making it ideal for use in circuits which experience large transient voltages.

In conclusion, the M1.5KE120AE3 TVS diode is an excellent choice when it comes to providing protection against transient voltages and surge currents. It is particularly useful in circuits which experience large amounts of static electricity or high voltage transients. It also provides a very low clamp voltage, along with a fast response time, making it suitable for a wide variety of applications.
