TVS – Diodes, or Transient Voltage Suppression Diodes, are one of the most important components of modern electrical systems, protecting them from transient voltage evoked by lightning strikes, power surges and electro-magnetic interference (EMI). The TV04A300JB-HF is a unidirectional diode type TVS, offering superior power handling and robust protection against electrical surges and field emission on higher frequencies. In this article, we will go over the application fields and working principle of the TV04A300JB-HF.

Application Fields

The TV04A300JB-HF is primarily used in automotive and industrial control systems for protection against transient voltages. It is recommended for use in voltage protection circuits up to a maximum peak pulse power of 1500W. Its high voltage breakdown ability provides superior protection against the sudden increase in current caused by lightning strikes, power surges and EMI. The TV04A300JB-HF is also designed to absorb energy from high frequency or low-energy lightening strikes.

The TV04A300JB-HF is ideal for use in portable electronic devices, automotive electronics, and computer peripherals. It is designed to be used in conjunction with other components, such as capacitors, inductors, and semiconductors, to form sophisticated circuits protecting devices from transient voltage. The TV04A300JB-HF is also suitable for applications that require high reliability and low noise, such as telecom equipment, internet of things (IoT) devices, and data centers.

Working Principle

The TV04A300JB-HF is built on a state-of-the-art silicon-based semiconductor technology, featuring a single integrated component with a robust construction. It offers superior protection against transient voltage surges and power peaks without additional components. This allows it to handle transient voltage that exceeds up to 1500W peak power.

The diode works by rapidly breaking down and absorbing transient voltage, providing a fast and reliable reaction to voltage spikes that do not exceed its breakdown voltage. The device is able to dissipate the energy created by the voltage surge and dissipate it in a safe manner, thus protecting the device from damage. The TV04A300JB-HF is able to do this thanks to its solid-state construction, enabling it to absorb and redistribute the energy of the surge away from the protected device.

Moreover, the TV04A300JB-HF is designed to work in high temperature conditions, with a power derating of 35% @ 85°C. This allows the device to protect circuits from excessive current even under severe environmental conditions. The diode is also resistant to high-frequency EMC radiation.

Conclusion

The TV04A300JB-HF is a highly reliable unidirectional TVS diode, offering superior protection against transient voltage surges and peak power of up to 1500W. It is designed to be used in various applications, including automotive electronics, portable electronic devices, telecommunications equipment, IoT devices, data centers, and many others. Moreover, its solid-state construction and its ability to work in high temperatures make it an ideal choice for reliable circuit protection in severe environmental conditions. Finally, the diode offers robust protection against high-frequency EMC radiation.
