TVS (Transient Voltage Suppressor) diodes are semiconductor devices used to protect electronic circuits from damaging overvoltage transients such as electrostatic discharge (ESD), electrical fast transients (EFT) and lightning. They are composed of specially designed diodes, zener diodes and other elements designed to suppress voltage transients. The 30KPA28A-HR is one such TVS diode which is specifically designed for high reliability, low power dissipation and excellent surge protection capability.

The 30KPA28A-HR is a unidirectional TVS diode which is designed for 12 Volt AC/DC and 24 Volt AC/DC applications. It has an excellent response time of less than 2 nanoseconds, meaning it can suppress voltage transients very quickly. It is also designed with low capacitance and low leakage current, making it ideal for low power applications.

The 30KPA28A-HR has a maximum power dissipation of 500 milliwatts and a maximum clamping voltage of 28 volts. The maximum working current is 8 amps and it has a breakdown voltage of 19 volts. It is rated for a maximum surge current of 30 amps and can handle transients up to 5,000 Watts.

The 30KPA28A-HR is designed for a variety of applications including telecommunications networks, industrial control systems, medical equipment, home appliances, office equipment, automotive systems and any other application requiring reliable surge protection. It is particularly suitable for systems which require fast response times and high clamping voltages.

The 30KPA28A-HR works by clamping a voltage transient at the device’s breakdown voltage. When the transient voltage rises above the diode’s breakdown voltage of 19 volts, it starts conducting current to suppress the overvoltage transient. The current is limited by the device’s maximum current rating to prevent damage. The 30KPA28A-HR then quickly recovers when the transient voltage is lowered again.

In conclusion, the 30KPA28A-HR is an excellent TVS diode for high reliability, low power dissipation and excellent surge protection. It is designed for twelve or 24 Volt AC/DC applications and has a maximum power capacity of 500 mW, a maximum working current of 8 amps and a breakdown voltage of 19 volts. Its very fast response time of less than 2 nanoseconds makes it ideal for applications where fast response is required and its maximum surge current rating of 30 amps makes it suitable for high power applications. Its excellent clamping voltage of 28 volts makes it suitable for a wide range of applications such as telecommunications networks, industrial control systems, medical equipment, home appliances, office equipment, automotive systems and more.
