Transient Voltage Suppression (TVS) diodes are a type of unidirectional device, with a variety of different case sizes to suit different application areas. The SMBJ20CD-M3/I is an example of a surface mount TVS diode which is equipped with a welded cathode. It features a minimum standoff voltage of 20V and a peak pulse power rating of 600W, and is suitable for use in many applications.

The SMBJ20CD-M3/I is ideally suited for high power transient voltage protection on sensitive electronics such as processors, memory, and other data lines or bus interfaces. This device is able to absorb high levels of power without being damaged, and its low leakage current ensures that it will not interfere with the functioning of the protected component. The SMBJ20CD-M3/I has an average clamping voltage of 28.8V, and its minimum breakdown voltage is 20V, ensuring it will respond quickly and efficiently to any transient voltage spikes or surges in the line.

The working principle of the SMBJ20CD-M3/I is based on the avalanche breakdown process. When the voltage exceeds the diode\'s reverse breakdown voltage, a sizeable number of mobile carriers are released. These carriers further propagate the cascade avalanche breakdown process, raising the voltage applied to the diode to rapidly suppress transient voltage spikes. This happens in a matter of nanoseconds, and is often referred to as surge clamping. The device is designed to have a short turn-off time, so the clamping process can be completed quickly, and the device will quickly resume its normal operation.

The SMBJ20CD-M3/I is a versatile device which can be used in a variety of applications. Its low clamping voltage ensures it is suitable for use as an ESD protection diode, and its peak pulse power rating makes it an ideal choice for protecting sensitive electronics from transient voltage spikes and surges. It also features a low leakage current, so it will not interfere with the functioning of the protected component. This makes the SMBJ20CD-M3/I a great choice for any application requiring a dependable, reliable, and fast response TVS diode.
