AK3-380C Circuit Protection

TVS (transient voltage suppressor) diodes are a type of semiconductor device used to protect sensitive electronic components from high-voltage transients, commonly known as "electrostatic discharge" (ESD). AK3-380C is a type of TVS diode which is widely used to protect sensitive electronics from overvoltage events. This article will discuss the application field and working principle of AK3-380C.

Application Field of AK3-380C

AK3-380C is a uni-directional TVS diode used to protect one-way current flow paths from overvoltage transients. Its low breakdown voltage of 3.8V and high peak pulse current of 1.5A make it suitable for use in a variety of applications. It is particularly well-suited for use in communications and computer systems, as it is capable of providing fast overvoltage protection. It can also be used in automotive, medical, and industrial applications where fast response to overvoltage transients is desired.

AK3-380C is designed and manufactured for use in a wide range of environments. It is capable of meeting a variety of standards, including MIL-STD-750F, JEDEC standard JESD78E and SABE-013. It also meets the requirements of the RoHS and REACH directives.

Working Principle of AK3-380C

AK3-380C is a variant of the common silicon-based TVS diode. It utilizes a PN junction to suppress overvoltage transients. When an overvoltage is encountered, the diode rapidly turns on, limiting the voltage applied to the load. During overvoltage events, the diode will briefly act as a low impedance path, allowing the transient energy to dissipate itself. After the transient has passed, the diode will turn itself off again, allowing the load to return to normal operation. This rapid response time makes AK3-380C an ideal choice for overvoltage protection.

AK3-380C is also designed for low let-through voltage. This means that the diode will clamp the transient to a low voltage level, thus protecting downstream components from damage. The diode also exhibits a very low leakage current under normal operating conditions, which helps to maintain operational efficiency.

Conclusion

AK3-380C is a widely used uni-directional TVS diode that provides excellent protection from overvoltage events. Its low breakdown voltage and high peak pulse current make it suitable for a variety of applications, including those in communications, computer systems, automotive, medical, and industrial use. Additionally, it meets a variety of standards and complies with the RoHS and REACH directives. The diode is also designed for low let-through voltage and low leakage current, providing excellent protection and operational efficiency.
