TVS - Diodes, also known as Transient Voltage Suppressor diodes, are designed to protect sensitive electronic components from electrical transients, such as lightning or electrostatic discharge (ESD). The SMBJ15CD-M3/I is a transient voltage suppressor diode designed to protect high-speed data lines such as USB and HDMI cables from voltage spikes. In this article, we will discuss the application field and working principle of the SMBJ15CD-M3/I.

The SMBJ15CD-M3/I is designed for use in applications such as USB cables, HDMI cables, Ethernet cables, and other high-speed data lines. The SMBJ15CD-M3/I is capable of handling up to 15 amps of current and is rated for a clamping voltage of 19V. The maximum working voltage is 30V and the operating temperature range is between -65°C and +150°C. The SMBJ15CD-M3/I is available in SMA and SMB packages and has a peak power handling of 500W at 8/20 nanosecond waveform.

The working principle of the SMBJ15CD-M3/I is based on a PN junction. The PN junction is a combination of two types of semiconductor material having one side that has an excess of electrons (n-type) and the other side having an excess of holes (p-type). When an external voltage is applied, the electrons and holes in the PN junction start to flow from the n-to-p side and p-to-n side respectively in a process called forward biasing. This forward biasing leads to a current flow across the junction. When a voltage spike is applied, the current flow across the junction increases significantly and this leads to a formation of an electrostatic field around the junction. This electrostatic field prevents the further flow of current by clamping the voltage.

The SMBJ15CD-M3/I has a peak pulse clamping voltage of 19V and can handle up to 15 amps of current. It has an ultra-fast reverse recovery time of 10 nanoseconds and an ultra-low capacitance of 1.2pF. The SMBJ15CD-M3/I is designed for use in high-speed data lines such as USB and HDMI cables and can protect the cables from voltage spikes up to 19V. The SMBJ15CD-M3/I is available in SMA and SMB packages and has a peak power handling of 500W at 8/20 nanosecond waveform.

In conclusion, the SMBJ15CD-M3/I is a transient voltage suppressor diode designed to protect high-speed data lines from voltage spikes. It has a clamping voltage of 19V and an operating temperature range of -65°C to +150°C. It has an ultra-fast reverse recovery time of 10 nanoseconds and an ultra-low capacitance of 1.2pF. The SMBJ15CD-M3/I is available in SMA and SMB packages and has a peak power handling of 500W at 8/20 nanosecond waveform.
