The TVS – Diodes application domain is a wide and varied field, with many disciplines such as aerospace, military, automotive, and communication all utilizing them for protection purposes. The MASMCJ85CA TVS diode is a silicon avalanche diode with a breakdown voltage of 5.5V and a power rating of 85W. Its peak surge current rating is 34A, and it has a maximum clamping voltage at Ipp of 9.2V.

The MASMCJ85CA can be used to provide ESD protection, as well as enhanced protection from inductive transient events and electrical surges. It is ideal for protecting high-speed data lines of all types, such as Ethernet, USB, HDMI, and others. It can also protect sensitive circuits from lightning and other induced spikes.

The MASMCJ85CA is a bidirectional device, meaning it can protect both in the current from an external source, as well as from a failure inside the protected device itself. This is achieved by the conduction of a current once the breakdown voltage of the diode is exceeded. When the breakdown voltage is reached, the diode will begin to conduct current, and the pressure placed on the protected device will be relieved.

The working principle of the MASMCJ85CA is based on the avalanche effect. This happens when the electric field intensity in the weakening depletion layer surpasses a certain level. This is what leads to a highly energetic electron-hole pair collision which then releases a lot of secondary electrons with an energy level greater than the avalanche breakdown voltage. This then leads to a current increase which in turn creates a short-term over-voltage.

The total breakdown voltage of the MASMCJ85CA TVS diode is made up of the peak avalanche breakdown voltage and the junction capacitive voltage. The peak avalanche breakdown voltage is the sum of the junction barrier potential plus the sum of the surface potential. The junction capacitive voltage depends on the rate of change of current. This voltage drop will increase while the ratio of the square root of the rate of change of current to the temperature will decrease.

TVS diodes can also provide surge absorption, and it is this function that is of the utmost importance when protecting high speed data lines. When the surge voltage reaches its peak value, the diode will absorb surplus energy and turn it into heat. This additional energy is then dispersed through the diode, relieving any pressure on the protected device and providing a much higher level of protection.

The MASMCJ85CA is a great choice for protecting devices from dangerous electrical surges, ESD, and inductive transient events. It is a highly efficient device that offers superior protection and reliable performance.
