TV04A580JB-HF Circuit Protection

A Transient Voltage Suppression (TVS) Diode, broadly speaking, is a diode intended to protect other electronics (circuits, components, and systems) from potentially damaging voltage transients. This type of diode, also known as a transil or thyrector, is designed to partially offset sudden voltage spikes or transients, such as those caused by an adjacent electrical equipment malfunction or induced by a nearby lightning strike. The TV04A580JB-HF, in particular, is a surge protection diode designed for high frequency applications with a maximum working voltage of 5.8V.

Operating Principle of TV04A580JB-HF

The TV04A580JB-HF is a low capacitance, dual-channel, high-speed TVS Diode that acts as a bidirectional transient voltage protection component. Its operating temperature range is from -40°C to 85°C and is capable of yet protection of up to 4.9V. It has two channels of protection, each rated up to 2.9V peak pulse power.

This diode begins its operation, or “turns on”, when a sustained voltage exceeds its breakdown voltage. When the voltage exceeds this threshold, the transient voltage is shunted to ground, limiting any further rise in voltage. The TV04A580JB-HF also has an internal ESD protection circuit that is capable of discharging those transient voltage builds up 16KV. This allows for more reliable protection and longer service without failure.

Application Field of TV04A580JB-HF

The TV04A580JB-HF is mainly used in automotive electronic systems, consumer electronics devices, electrical appliances and industrial equipment. Due to its low capacitance design, it is also used in high frequency communication lines, including DSL, coaxial cables, and RF cables. The diode also has excellent ESD protection of up to 16KV, allowing for greater sustained protection and a longer lifetime.

This diode has been proven highly reliable in many high and low-voltage applications. Its low capacitance and stringent VBR enables it to be used in high-frequency applications, and its low clamping voltage and higher surge current ratings make it suitable for industrial applications such as medical equipment, motors, and pumps. Additionally, its low leakage current and high ESD ratings enable it to provide reliable performance in automotive and consumer electronic applications.

In summary, the TV04A580JB-HF is a low capacitance and high-speed, dual channel TVS Diode designed for high-frequency applications, and it offers maximum protection to circuits, components, and systems from damaging voltage transients.
