MXLRT100KP150CA

TVS (Transient Voltage Suppressor) diodes are electronic components used in high voltage and current applications, such as automotive, industrial and consumer electronics, to protect against over-voltage transients. The MXLRT100KP150CA is a silicon epitaxial planar (double-sided) junction diode designed as an integrated circuit transient voltage surge suppressor.

The MXLRT100KP150A device consists of two, double-sided polysilicon junction diodes, one of which is reverse-biased to serve as a surge protection diode. Each diode has an integrated PNPN structure, which provides additional protection against high voltage surges. The device also includes two resistors, one on each side of the device, which help to reduce the transient voltage. The device is designed to be highly reliable and can withstand up to 100kV surge currents of up to 150A.

The main application environment for the MXLRT100KP150CA is in automotive, industrial and consumer electronics devices, such as LCD TVs, PCs and smartphones, used in environments where there is a risk of over-voltage transients. The device is typically used in conjunction with other protection components, such as surge absorption varistors, for maximum protection against over-voltage transients. The device is also used in AC adapters, chargers and other devices used in high voltage and current applications.

The working principle of the device is based on a process known as PNP (Pseudo Negative-Positive) junction breakdown. In this process, the junction between the base and a collector is reverse biased. In this way, the base emitter junction acts as a diode blocking any positive voltage below the breakdown voltage (VBR). When the voltage rises above this breakdown voltage, the diode is “pushed into avalanche” and a surge of current is released. This current is then gradually absorbed by the two resistors present in the device. The two resistors help to reduce the transient voltage thus protecting the device against any damage.

The MXLRT100KP150CA is an extremely reliable and compact device, capable of withstanding high voltage and current surges. It is used as a protection device in automotive, industrial and consumer electronics applications to protect against over-voltage transients. It works on the principle of PNP junction breakdown, and absorbs the transient voltage using its two integrated resistors.
