Transient Voltage Suppressor(TVS) diodes are widely used to protect the circuits from voltage transients caused by electrostatic discharge (ESD) and other transient conditions. ATV02W360-HF, a low-voltage Controlled Avalanche Rectifier developed by ATV Semiconductor, is a special type of TVS diode that exhibits a combination of fast response time and high clamping efficiency in suppressor devices. This article presents the application field and working principle of ATV02W360-HF.

Application Field: ATV02W360-HF is mainly used in applications where rapid response time to rising voltage and low residual voltage are required. It is also suitable for protecting delicate components and circuits from malfunction caused by the ESD. Because of its extremely low capacitance and high surge capability, ATV02W360-HF can be used in various applications such as automotive, industrial, medical, military and communication applications.

Working Principle: The ATV02W360-HF is designed using an avalanche process, which involves two diodes connected in a back-to-back configuration. This creates a high resistance in one direction and low resistance in the other direction. Under normal operational conditions, the device experiences a forward directed bias voltage and blocks the current from flowing. When a transient event occurs, the voltage across the device increases above the diode’s avalanche threshold and current begins to flow. In this way, the diode can clamp the voltage down to a safe level when voltage surges occur.

ATV02W360-HF is also designed with an integrated voltage limiting functionality, which is used together with the avalanche process to protect sensitive components by limiting the maximum voltage level. When the voltage reaches the clamping voltage, the diode will clamp the voltage to a safe level and absorb the energy.

In addition, ATV02W360-HF has a fast response time, meaning it can respond to voltage transients within a few nanoseconds. This fast response prevents damage to sensitive components by quickly clamping down the voltage before it has a chance to cause permanent damage.

ATV02W360-HF devices also have a reverse leakage current protection feature, which prevents current from flowing in the reverse direction when the device is in standby mode. This feature helps to protect the circuit from erroneous operation or malfunction.

Overall, ATV02W360-HF is a versatile and reliable device designed to protect sensitive components and circuits from voltage transients that could cause malfunction or damage. It is a dependable protection device with fast response time, low capacitance, high surge protection capability and reverse leakage current protection.
