TV04A351J-HF Circuit Protection

TVS - Diodes

TV04A351J-HF is a TVS diode commonly used in commercial products to protect sensitive electronic components from overvoltage or voltage spikes. It is highly reliable and robust, making it an ideal choice for commercial applications. This article will discuss the application field and working principle of this device.

Application Field

TV04A351J-HF has a wide range of applications, including industrial and automotive electronics, telecommunications, consumer, and military/aerospace equipment. Because of its fast response speed and low leakage, it can protect delicate circuit components from high voltage transients that may damage them. This makes it ideal for applications that are subject to frequent power surges or sudden changes in voltage.

TV04A351J-HF has a wide operating temperature range, making it suitable for outdoor applications. It is also highly resistant to environmental influences, such as dust, moisture, vibration, and shock. It can be used in high-noise-level applications as well as in applications with limited power.

Working Principle

TV04A351J-HF is a unidirectional device, which means it only conducts current in one direction. It works by clipping the exceeding voltage to a preset value, thus preventing it from harming other components. When the operating voltage exceeds a certain threshold, the TVS diode initiates a rapid clamping action that diverts the current away from the sensitive components.

TV04A351J-HF is available in both an axial (through-hole) package and a surface-mount package. Depending on the application, the through-hole package is suitable for higher transient voltages up to 3000W peak pulse power, while the surface-mount package can handle up to 1500W peak pulse power. In addition, TV04A351J-HF can handle both unidirectional and bidirectional transients.

TV04A351J-HF is designed with an active low capacitance structure that allows it to clamp high frequency transient voltages more efficiently. This active structure also reduces the reverse leakage current when the voltage is below the breakdown voltage.

TV04A351J-HF is an extremely reliable and efficient TVS diode for a variety of applications. It has a wide operating voltage range, wide temperature range, and low leakage current, resulting in excellent performance when used in various electronics systems. This makes it an ideal choice for commercial/industrial/automotive, telecommunications, and military/aerospace applications.
