3KP220CA-B

TVS - Diodes are surge protection devices made with the combination of a breakdown power diode, transient voltage suppression Zener diode, and an epoxy interface. The model 3KP220CA-B is a Transient Voltage Suppressor (TVS) diode used to protect sensitive components from over-voltage transients. These devices are ideal for protecting port I/O interfaces from damage caused by excess voltage on the line such as ESD, EFT, and more.

The 3KP220CA-B is able to limit the maximum transient voltage to a safe level when it is triggered. It is designed to operate within the -20℃ to +80℃ range with a maximum reverse leakage current of 2mA, and a maximum stand-off voltage of 221V. The circuit also allows for a maximum working voltage of 280V. The maximum peak pulse power dissipation of this model is 8KW; while the bi-directional applications support 11A peak pulse current.

This particular diode is ideal for LED TV application fields, and telecom applications. The 3KP220CA-B TVS Diode works by connecting the anode of the diode to the positive line, and the cathode to the negative line of the circuit. When the supply voltage is within the breakdown voltage level of the device, the diode will not conduct, and the load will not be affected. However, when the voltage exceeds the breakdown voltage (Vbr) of the diode, it will start to conduct, and reduce the excess voltage.

Essentially, its design is based on a precision Zener diode combined with a transient power diode that helps to limit the maximum transient peak voltage. This means the device increases the current flow sufficiently to clamp the transient voltage. The 3KP220CA-B offers excellent clamping capability and low leakage current to ensure the highest level of protection. It also helps protect against over-voltage and reverse-voltage transients.

To summarize, the 3KP220CA-B Transient Voltage Suppressor (TVS) diode provides protection from high-energy transients for LED TVs and telecom applications. Its design is based on a precision Zener diode combined with a transient power diode, which helps to limit the maximum transient peak voltage. This ensures the highest level of protection against over-voltage and reverse-voltage transients.
