TVS - Diodes are a type of semiconductor protection device that are used to protect electronic systems or circuits from transient overvoltage caused by electrostatic or inductive effects. They work by providing a low impedance path for transient voltages to be redirected away from the protected system or circuit. The 30KPA120CA is one type of this protection device.

The 30KPA120CA has a peak pulse power rating (PPP) of 30kW and a clamping voltage of 120V. It is a surface-mount diode that is designed for use in overvoltage protection applications. It is designed to protect against voltage transients caused by inductive or electrostatic discharges and is capable of handling high peak currents of up to 60A. The 30KPA120CA can be used in a variety of applications, such as AC line protection, automotive circuits, and consumer electronics.

The 30KPA120CA features reverse leakage current of less than 25mA, a low clamping voltage of 120V, and a maximum leakage current of 3A. It has a low capacitance of 250pF, which makes it suitable for high speed signal transmission applications. Additionally, the 30KPA120CA has a low dissipation factor, which allows it to be used effectively in high-current circuits. It is also designed to work with a wide range of operating temperatures, from -55°C to +125°C.

The working principle of the 30KPA120CA is based on the PN junction of a diode. When an overvoltage is applied to the PN junction, the diode conducts current from the external circuit and into the diode’s junction. This process is called a “ avalanche breakdown process”, which protects the circuit by diverting the current away from the component or circuit that is being protected.

The 30KPA120CA is a reliable and cost-effective protection device for a wide range of applications. Its low capacitance allows it to work efficiently in high-speed data transmission circuits, while its low reverse leakage current ensures that the diode does not draw unnecessary current from the protected circuit. Additionally, the device’s low clamping voltage makes it suitable for a variety of voltage protection applications, including AC line protection, automotive circuits, and consumer electronics.
