TVS (Transient Voltage Suppression) Diodes are devices designed to protect all types of sensitive electronic equipment from overvoltage transients. The SMCJ78A V6G is a unidirectional TVS diode that is widely used for surge protection. It is a very robust device with a working voltage range of 6.8 V to 176 V and surge current rating of 5.1kA.

The SMCJ78A V6G is a multifunctional device offering voltage transient protection, EMC filtering and degradation of high frequency noise. It can also be used to suppress common mode and differential mode ESD (Electrostatic Discharge) events. The device ensures high reliability during high-frequency transients, effectively shielding the circuit from high-voltage transients. It is well-suited for a wide range of application fields that include industrial, medical, consumer, automotive and communication systems.

The SMCJ78A V6G is an avalanche diode, which means that when the diode is forward biased, it is turned on by the generated avalanche effect. The avalanche current is essentially the current that flows through the diode when the breakdown voltage is exceeded. The breakdown voltage of the device determines the reverse blocking voltage for the device and is used to protect sensitive components from excessive transient voltages.

In operation, the SMCJ78A V6G acts as a low-impedance insulator, allowing fast forward current to pass with very little voltage drop. When the reverse voltage exceeds the breakdown voltage, the diode will then act as a high-impedance insulator preventing the flow of high-voltage transient energy. The device provides superior EMC filtering, allowing any stray high- frequency noise to be suppressed before it enters the sensitive components.

The SMCJ78A V6G can be used in a wide range of application fields that include automotive, communication, consumer electronics, and industrial and medical systems. In automotive systems, the device can be used to protect the car\'s electrical system from overvoltage transients that may occur in situations such as engine stalling, power surges, and lightning strikes. In medical systems, the device can be used to protect patient monitors and other medical equipment from electrical surges, as well as providing EMC filtering for high-frequency noise. In consumer electronics, the device can be used to protect TVs, computers, and other sensitive devices from overvoltage transients that can damage the internal components.

The SMCJ78A V6G is a rugged, reliable TVS diode that is designed to protect sensitive electronic components from overvoltage transients. The device provides superior EMC filtering, as well as low-impedance forward conduction and high-impedance reverse conduction. It is well-suited for a wide range of application fields, including automotive, communication, consumer electronics, and industrial and medical systems.
