5KASMC40AHM3/9A

Transient Voltage Suppressor Diodes (TVS-Diodes) are electronic components, which are designed to protect sensitive electronic components from overvoltage transients and other power surges. The 5KASMC40AHM3/9A is one such commonly used protection device.

• Application Field:

  This TVS-Diode is used for bi-directional ESD protection in a number of different applications, including personal computers, computer peripherals, and consumer electronics. It is also used in automotive and industrial applications, especially in areas exposed to environmental hazards such as moisture and steam.

• Working Principle:

  The 5KASMC40AHM3/9A TVS-Diode is based on the popular Zener diode structure but with an added avalanche breakdown mechanism. It works by using a voltage decline. When the diode is subjected to a voltage greater than its breakdown voltage rating, it rapidly falls to a lower voltage. This sudden voltage shift limits the power surge that can damage connected electronic components and prevents them from being fried. The device also has an positive temperature coefficient which prevents it from overheating, and thus ensures reliable operation.

The 5KASMC40AHM3/9A is designed to be used in 5V and 12V systems and can interrupt power surges of up to 400W. It is made of a robust and reliable Aluminum nitride substrate material, which ensures high temperature capability and resistance to moisture and steam. Its very low leakage current also ensures low power dissipation and high reliability over time. In addition, the device has a high maximum clamping voltage and fast clamping response time, making it an ideal choice for use in critical applications where fast response is needed.

In conclusion, the 5KASMC40AHM3/9A TVS-Diode is an effective and reliable power surge protection device. Its robust construction and features make it an ideal choice for both automotive and industrial applications. Its low leakage current, high temperature capability, and fast response time make it particularly suitable for applications which need quick and reliable protection from power surges. As such, the 5KASMC40AHM3/9A is an essential component for protecting sensitive electronic components in a wide range of applications.
