TVS - Diodes

TVS - Diodes, or Transient Voltage Suppression Diodes, are a special type of diode that is used to protect electronic devices from high voltage transients. They are commonly used in the automotive, aerospace, industrial control, and medical device markets. They have the unique feature of having a low forward breakdown voltage that is much lower than regular diodes, which is usually around 30 to 40 volts. When it comes to protecting your electronic systems, a TVS diode is one of the most reliable components available.

SMP15A-M3/85A Application Field and Working Principle

The SMP15A-M3/85A is a surface mount Transient Voltage Suppressor (TVS) diode designed for use in automotive, aerospace, and industrial control applications. This diode has a low breakdown voltage rating of just 5.4V, making it very effective in blocking high voltage transients that could damage sensitive electronics. It is constructed using a silicon chip, and it features a high surge current handling capability of up to 200A. This diode is both RoHS compliant and UL recognized.

The working principle behind a TVS diode is based on the same principles as a traditional diode. As current flow is applied to the diode, a voltage drop is applied across the diode as a result of the PN junction, which act to limit the current passing across the diode. In the case of the SMP15A-M3/85A, this voltage is 5.4V, which is far lower than a regular diode. When exposed to a high voltage transient, the diode will “clamp” the voltage to the PN junction voltage, thus protecting the electronics downstream.

The SMP15A-M3/85A is designed primarily for automotive and aerospace applications, however it can also be used in industrial control applications. In automotive applications, it is typically used to protect against ESD or voltage spikes that can occur during engine starts or stops. In aerospace applications, it can be used to protect against high voltage transients and ESD. In industrial control applications, it can be used to protect control systems from high voltage transients and ESD.

The SMP15A-M3/85A is a very reliable component, and is designed for long-term use in harsh environments. It is UL recognized, and is RoHS compliant. Its low breakdown voltage makes it an ideal choice for protecting sensitive electronics, and its high surge current handling capability will ensure that it can handle even the strongest voltage transients.

In conclusion, the SMP15A-M3/85A is an excellent choice for protecting electronics from high voltage transients and ESD. Its low breakdown voltage makes it ideal for use in sensitive electronic systems, and its high surge current handling capability ensures that it can handle even the most extreme voltage transients. It is RoHS compliant, and UL recognized, making it the ideal choice for any application requiring reliable protection from voltage transients.
