ATV04A401J-HF TVS-Diodes are designed specifically for high-speed, pulse and data line protection applications, such as LVDS and monolithic coaxial lines. The device uses an advanced SiGe technology to provide a valuable and reliable data protection solution in critical applications. It can prevent components and system damage caused by EMI/EFI, lightning and other over-voltage events.

ATV04A400J-HF offers a low capacitance of 0.2pF for minimal signal distortion, and a fast clamping response to protect sensitive electronic devices when subjected to ESD, REMI and ESD pulses. It also has an ultra-low breakdown voltage of 6.8V. This product is designed to meet Qualified Product List (QPL) qualifications for high-speed networks with a surge up to 2000W (10/1000μs).

ATV04A400J-HF is available in a compact 3-pin SOT-23 package. This small size makes it perfect for use in a compact space, such as cellular phones and other mobile devices. The low-capacitance body also helps to reduce signal distortion and is ideal for protecting sensitive data lines.

The working principle of ATV04A400J-HF is based around the capacitance-voltage characteristics. When the device is exposed to an over-voltage, it will form a capacitive-type diode parallel to the protected line, which will then clamp the over-voltage very quickly. This process will form a current-limiting path and allow the rest of the circuit to remain protected. The TVS diode also acts as a short circuit, and when the over-voltage is removed, the diode will return to its off-state. This process ensures the device and circuit remain safe during the entire process.

ATV04A400J-HF is ideal for high-speed data line protection applications as it can withstand high power surges without sacrificing signal integrity and is designed to meet the needs of high-speed networks. The device is also suitable for use in portable and mobile devices due to its small size and low capacitance. This product is a reliable and effective solution for protecting sensitive electronic devices against over-voltage events.
