Introduction

AK3-076C-12 is a type of Transient Voltage Suppression (TVS) diode. It offers low leakage current, high surge current handling capability, and fast response time. This diode offers over-voltage protection from high energy transients in sensitive electronic systems.

Application Fields

AK3-076C-12 is widely used in portable electronic devices, video cameras, telecommunication equipments, medical equipments, automotive circuit protections, UPS and power supples etc. It can be used for protecting sensitive semiconductor components in the application of high speed data line, USB port, etc.

Working Principle

TVS diodes can limit the voltage stress applied across two-terminal device such as integrated circuits. The applied voltage of standard diode is limited by its reverse breakdown voltage, which can be sustained for a long time without any damage. However, when the applied voltage exceeds the reverse breakdown voltage of the diode, it will be damaged.That\'s why TVS diode is often used in these applications. The reverse breakdown voltage of the diodes is much lower than the diode, it can clamp the voltage within a certain range and provide better over-voltage protection in these applications.When the voltage of the circuit exceeds the breakdown voltage of the diodes, the diodes will conduct the current and dissipate the excess energy. The diodes can respond rapidly to provide protection against over-voltage transients.

Features

AK3-076C-12 is a bidirectional TVS diode with an operating voltage of 12V. It provides superior over-voltage protection in sensitive electronic circuits. It has wide operating temperature range from -65°C - +150°C and is capable of withstanding surge current up to 500A (8/20μS). The diode also has low leakage current which makes it suitable for low power circuits operation.

Conclusion

AK3-076C-12 is a popular type of transient voltage suppression diode. It offers low leakage current, fast response time and high surge current handling capability. This diode can be used for protecting sensitive semiconductor components in various applications, such as portable electronic devices, video cameras, telecommunication equipments, medical equipments, automotive circuit protections, UPS and power supples etc.
