30KPA70CA-HRA

Transient Voltage Suppressors (TVSs) are used to protect a circuit by shunt-ing over-voltage transients to ground and thus limiting their amplitude to a safe level. TVS diodes are designed to protect against Electrostatic Discharge (ESD), Lightning Strikes, Inductive Load Switching, and Electrical Fast Transients (EFT). A 30KPA70CA-HRA, commonly referred to as a “gasplasma” TVS, is a dual-element, unidirectional, transient voltage surge suppressor designed to protect sensitive electronic circuits.

The 30KPA70CA-HRA is a type of voltage suppressor that utilizes a gas and a plasma path in parallel with the diode. Both paths are characterized by breakover voltages and low conductance in the off state, allowing circuit protection from unwanted voltage transients. In comparison to a single element TVS diode, which has just a single path for the current to flow, the 30KPA70CA-HRA has two paths which help to provide more effective protection of sensitive circuits.

The 30KPA70CA-HRA’s predominant application field is power supply and power supply line protection of computers, TVs, audio components, and other digital equipment. It can be used in applications where transient over voltage protection is desired due to potential EFTs, ESDs, or lightning. It is also used in lines which are at risk of being subjected to power surges and can be connected in series with the line connected to the control signal circuit to protect the signal line.

The 30KPA70CA-HRA operates based on two principle theories of surge protection, the Breakover Voltage Principle and the Avalanche Breakdown Principle. The Breakover Voltage Principle works by limiting the voltage that is supplied to the device and occurs when the device is placed in a high electric field strength. The Avalanche Breakdown Principle works by providing the device with a low breakdown voltage and a high holding current. This will allow the device to absorb a transient over voltage and convert it into a low steady-state voltage Any remaining energy will be dissipated as heat.

The 30KPA70CA-HRA is designed with a high power capability and a low capacitance, making it an ideal choice for protection from Electrostatic Discharge (ESD) and Electrical Fast Transients (EFT). It has a high withstand voltage (VWM) and low clamping voltage (VC), and is available in a variety of lead-free configurations and package styles. In addition, the 30KPA70CA-HRA has a low on-state leakage current and a low capacitance. This makes it suitable for use as a ESD protection device in applications such as telecommunications, automotive, and consumer electronics.

In summary, the 30KPA70CA-HRA is a dual-element, unidirectional transient voltage surge suppressor designed to protect sensitive electronic circuits from ESD, lightning strikes, inductive load switching, and EFTs. It is suitable for a wide range of applications, such as power supply and power supply line protection, and provides effective protection of sensitive circuits. It operates based on two principle theories of surge protection, the Breakover Voltage Principle and the Avalanche Breakdown Principle, and has low on-state leakage current and a low capacitance.
