Introduction to TVS - Diodes

Transient voltage suppression diodes, commonly known as TVS diodes, are a type of electrical component used to protect other electronics from sudden voltage spikes, which can cause damage or malfunction. TVS diodes are generally semiconductor diodes, and are designed to absorb and dissipate the energy from high voltage surges. They can be used in a variety of applications including commercial, industrial, medical, automotive, aviation, and power electronics.

30KPA43AE3/TR13 Application Field and Working Principle

The 30KPA43AE3/TR13 TVS Diode from Nexperia is a surface mount transient voltage suppression diode designed for electronic protection against surge voltages in automotive applications. This diode is a low capacitance transient voltage suppressor device that can absorb high energies over a wide range of operating conditions. It has a reverse standoff voltage of 43 Volt, a clamping voltage of 95 Volt, and a maximum peak pulse current of 30A. It is packaged in SOT-23 package.When a surge voltage is applied, the 30KPA43AE3/TR13 works in the following stages:

• The reverse breakover voltage level is reached, and the diode begins to conduct.
• The diode begins absorbing the energy from the surge.
• Once the maximum current is reached, the diode’s voltage begins to drop, and the energy from the surge is dissipated.
• Once the maximum clamping voltage is reached, the diode stops conducting and the surge is effectively absorbed.

This TVS diode is designed for use in automotive applications, such as car audio systems, car security systems, and car power systems. It is designed to protect sensitive electronics from voltage transients, such as those caused by a car engine starting, or from a sudden electrical surge. This diode is also suitable for high-temperature operation, and can handle temperatures up to 150 deg C.

Conclusion

The 30KPA43AE3/TR13 TVS Diode from Nexperia provides a reliable and efficient way of protecting sensitive electronics from sudden voltage surges, while also being able to handle high temperatures. This diode is designed for use in automotive applications, and is a great choice for anyone looking to protect their car audio system, car security system, or car power system from voltage transients.
