The SMCJ100ATR is a Transient Voltage Suppressor (TVS) diode. This device gives protection to a variety of systems and components from sudden strong voltage spikes.

The SMCJ series of diodes consists of three different types, the SMCJ100 ATR being the one with the highest breakdown voltage of 100 Volts. The SMCJ100ATR diode is a bidirectional diode, which means that it can work in reverse polarity to its normal bias. It should be noted that the bias should be reversed after a breakdown has occurred in order for the device to work.

The main application for the SMCJ100ATR diode is to protect against ESD (Electrostatic Discharge) or overvoltage protection. It is also used in applications where other overvoltage protection cannot be used, such as protection against surges caused by lighting. The device is also used to prevent permanent damage to sensitive electronic equipment from spikes in voltage.

The working principle of the SMCJ100ATR diode is quite simple. In normal conditions, the diode acts as a high-impedance device, meaning that it does not draw any current and will not interfere with the normal operation of sensitive electronic equipment. However, should a voltage spike occur, the diode will become ‘forward biased’. The current then flows freely through the diode, and this limits the total voltage surge seen by the connected equipment.

The SMCJ100ATR diode is constructed using a glass and metal package, containing a series of juntion diodes that are specially designed for maximum breakdown voltage. The glass and metal package is then sealed with a epoxy which ensures durability and resistance to temperature, humidity and vibration.

The SMCJ100ATR diode is also designed with a very fast response time, which is necessary to protect any connected equipment from damage due to voltage spikes. In addition, the diode has a very low clamping voltage, meaning that it will not interfere with the normal operation of the equipment it is protecting.

Overall, the SMCJ100ATR is an excellent device for a range of applications that require high-voltage protection, such as overvoltage protection, electrostatic protection, and protection against surges caused by lighting. The device is also relatively small in size, making it ideal for applications that require a small form factor.
