P4KA30HE3/73

The P4KA30HE3/73 is a voltage-dependent overvoltage suppressor with a breakdown voltage of 30V and a peak transient power dissipation of 700W. This TVS diode belongs to the family of Transient Voltage Suppression Diodes and is used in many different applications. The device is designed to clamp the voltage that is applied to it in order to protect sensitive electronic components from overvoltage transients. As the voltage across the diode increases, the current through the diode also increases. At a certain point, called the breakdown voltage, the current will reach the maximum level and the device will begin to clamp the voltage. This process helps to protect the components from the damaging effects of an overvoltage transient.The P4KA30HE3/73 can be used in applications where there are relatively high transients such as industrial, automotive, and consumer electronic applications. It can also be used in circuits that require low power dissipation, such as solar, LED and power supply applications.The working principle of the P4KA30HE3/73 is based on the principle of field-effect modulation. When a voltage is applied to the device, it creates an electric field which causes the electrons in the semiconductor material to move, allowing the current to flow. This effect is referred to as the diode’s avalanche effect. When the voltage across the diode reaches the breakdown voltage, the electrons will no longer be able to move and the current through the diode will be limited to the maximum current specified for the device. This mechanism helps to protect the components from the damaging effects of an overvoltage transient.In conclusion, the P4KA30HE3/73 is a voltage-dependent overvoltage suppressor that belongs to the family of TVS Diodes. Its working principle is based on the field-effect modulation of electrons in the semiconductor material. It can be used in a variety of applications, where it helps to protect sensitive electronic components from overvoltage transients.
