TVS-Diodes, a vital component in the world of electronics, are becoming increasingly important in many different applications. The MP4KE82AE3 has been developed to supply protection against voltage transients and is a very popular choice for numerous applications. This article will look at the MP4KE82AE3’s application field and working principle.

Applications

MP4KE82AE3 protection devices are primarily designed for use in automotive power supplies, where high levels of noise can be experienced. This includes systems such as LED headlights, motor control modules and airbag systems. TVS-Diodes can also be used in high-power computer and industrial systems, as well as data and medical systems. They can help prevent power surges and help the system components remain safe in the event of an emergency.

Working Principle

TVS-Diodes, such as the MP4KE82AE3, work by redirecting excessive noise voltages away from the system’s sensitive components. This helps to prevent damage due to power surges or interference from other components. The working principle of a TVS-Diode is based on the ability of semiconductor materials to conduct electricity. When more voltage than what is normal is applied to a device, the semiconductor material will quickly transition into a conducting state, effectively preventing the voltage from impacting the device’s sensitive components. The rate at which this transition occurs is known as the breakdown voltage, and it is this breakdown voltage that determines the type of protection provided by the device.

The MP4KE82AE3 offers a breakdown voltage of 6.2 volts, which is suitable for a variety of applications. This device can absorb up to 7.5kA of surge current and offers an excellent protection against both ESD and lightning-induced surges. This device also has an extremely low cut-off voltage, allowing it to provide protection even when the device’s voltage is lower than usual. Furthermore, the MP4KE82AE3 has a very low leakage current, making it suitable for use in sensitive systems.

The MP4KE82AE3 is also extremely durable, due to its high operating temperature and ability to withstand multiple transients. The device is capable of operating in temperatures up to 125°C and is manufactured using a process that includes a gold-based bond wire. This bond wire helps to ensure that the device can withstand shock and vibration, while also providing a reliable connection.

Conclusion

The MP4KE82AE3 is an excellent choice for protecting sensitive components in various applications, due to its breakdown voltage, surge-current rating, cut-off voltage and leakage current. This device is also extremely durable, thanks to its high operating temperature and golden bond wire. Whatever application it is used in, the MP4KE82AE3 offers excellent protection against power surges and interference, helping to reduce repair costs and improve system reliability.
