Transient Voltage Suppressor (TVS) diode is a semiconductor component used to control and suppress circuit over-voltages caused by power surges or electrical spikes that may occur during lightning storms or in high-current switching applications. The SMCJ100CA-M3/9AT is a specific type of TVS diode that provides transient voltage and spike protection for components in a range of industrial, commercial and consumer-level applications.

The SMCJ100CA-M3/9AT is designed with a minimum breakdown voltage of 7V up to a maximum breakdown voltage of 420V. It has a peak pulse power rating of 1500W and is available in multiple packages such as surface mount, through-hole and small-outline plastic packages. Its surge current rating is 18A and it has a standoff voltage of 9.4V. The device is RoHS compliant and is ideal for load dump protection.

The SMCJ100CA-M3/9AT TVS diode offers a variety of protection in a variety of applications. It is often used in automotive electronics, such as engine control units, safety systems, airbags, and ABS systems. It is also used in computing and communication systems where it can help protect against EMI interference. This type of TVS diode is also often used in power conversion systems, industrial and consumer appliances, and general purpose circuit protection.

The main purpose of a TVS diode is to provide a low impedance path to ground for high-runaway voltages. The SMCJ100CA-M3/9AT achieves this by utilizing their breakdown voltage characteristics and their ability to absorb or channel the excess energy away from sensitive components during an over-voltage event.

When an overvoltage event occurs, the voltage rises above the breakdown voltage of the TVS diode. This causes a breakdown current to flow through the diode, which is proportional to the amount of energy being released. The breakdown current is then directed away from the load, providing a low impedance path to ground. In this way, the SMCJ100CA-M3/9AT TVS diode effectively clamps and suppresses the over-voltage, protecting the load from damage.

In summary, the SMCJ100CA-M3/9AT is a versatile TVS diode that is highly effective in providing protection from electrical over-voltage events in a range of applications. It is designed with a minimum breakdown voltage of 7V and can handle up to a maximum breakdown of 420V. It has a surge current rating of 18A and a standoff voltage of 9.4V. This device is RoHS compliant and is ideally suited for load dump protection.
