TVS (Transient Voltage Suppressor) diodes, also known as avalanche diodes, are a special type of diode which is designed to protect sensitive electronic components from high voltage surges. TV15C480J-HF is one of the leading TVS diodes. This article will discuss the application field and working principle of TV15C480J-HF.

The TV15C480J-HF is designed for use in automotive applications. It can be used to protect the power supply lines of microcontrollers and other sensitive devices from overvoltage transients. Additionally, it is also capable of providing ESD (Electrostatic Discharge) protection up to 8kV HBM (Human Body Model). It has a peak pulse power rating of 1500W and can operate from -55°C up to 175°C.

The working principle of TV15C480J-HF is based on the avalanche breakdown theorem. Avalanche breakdown occurs when a high electric field is applied to a semi-conductor material, causing the depletion region to grow until it reaches the breakdown point. At this point, the electric field is so strong that it can no longer sustain the depletion region and it suddenly collapses, resulting in a high current flow. The high current then gets discharged through the diode, protecting the device from the surge.

The TV15C480J-HF is ideal for protecting against overvoltage transients and ESD events, and is capable of operating at extreme temperatures. Its combination of features makes it a great choice for automotive applications where such protection is necessary.
