30KPA45A-HRA

TVS - Diodes

The 30KPA45A-HRA is a TVS (Transient Voltage Suppressor) diode, often used to protect circuits and components from potential electrical damage due to transients or temporary overvoltage conditions. It falls under the category of a Low Capacitance Unidirectional Diode which is one of the faster recovery TVS diodes available. It is designed to efficiently absorb and dissipate high-speed surge voltages up to 45 amperes.

Application Field

The 30KPA45A-HRA is described as low capacitance diode and as such can be used to protect high speed signals and cables. Being able to dissipate single-pulse energy of up to 15 kilojoules, it is mainly employed for protection from electrical overvoltage conditions in home electronics, personal computers, automotive and industrial systems. It is designed to protect communications, audio, video and data line applications from ESD (electrostatic discharges) as well as lightning and other high energy surge events.

Working Principle

When a TVS diode is exposed to a voltage surge, its internal circuit is quickly initiated and a surge current goes through the diode and is absorbed by its PN junction. This vastly reduces the surge voltage level and helps protect the device beyond it. As the surge moves through the diode, it produces heat, which is quickly dissipated through the diode into its cooling environment. The diode is designed with a low-capacitance PN junction that allows it to react quickly and efficiently to the transient voltage surge. This makes it ideal for high-speed applications such as signal line protection and ultrafast protection from overvoltage conditions.

Conclusion

The 30KPA45A-HRA is an efficient and reliable TVS diode often used for protection from transients and overvoltage conditions in home electronics, personal computers, automotive and industrial systems. It features a low capacitance PN junction that enables it to quickly react to the transient voltage surge and provides a safe and robust level of surge protection.
