A Transient Voltage Suppression (TVS) Diode is a semiconductor device used to protect sensitive electrical components from damage caused by transients, overvoltage, and voltage spikes. TVS Diodes provide up-to-date protection against harmful voltage spikes and overvoltage surges, providing overvoltage protection and dynamic switching speeds that are unmatched in the industry. A TVS Diode is designed to protect against breakdown overvoltage, electrostatic discharge, and other high-frequency impulses that can occur when there is an electrical surge.

SMB8J30CA-M3/5B is an SMA (Surface Mounted Type) TVS Diode that combines uni-directional and bi-directional protection in the same package. This device offers overvoltage protection from high-frequency transients up to 25V and up to 12A. Its low capacitance and low leakage current, as well as its high surge and reverse break down voltage, make it ideal for protecting high speed circuits from overvoltage conditions. The SMB8J30CA-M3/5B is rated for a working temperature range of -55C to +150C and is packaged in a SMA case.

Application Field

SMB8J30CA-M3/5B is a versatile device that can be used for a wide range of applications. Its primary application is for protecting sensitive electronic circuits from transients and overvoltage surges. It\'s ideal for use in automotive electronics, IoT, consumer electronics, industrial electronics, telecommunication, and medical devices. In addition, it can also be used for ESD protection, power supply protection, and for protection against EFT and surge pulse.

Working Principle

The SMB8J30CA-M3/5B is a uni-directional and bi-directional overvoltage protection diode. It acts as a barrier to protect sensitive components from damage associated with voltage spikes, overvoltage, and transients. The TVS diode works by clamping the voltage when it exceeds the device\'s rating. This prevents the voltage from reaching the device that the diode is protecting.

The SMB8J30CA-M3/5B has a peak pulse power of 1200 W, a rated clamping voltage of 25 V, and a peak surge current of 12 A. It also features a low capacitance of 0.2pF and a low leakage current of 3mA. When an overvoltage or transient voltage condition is detected, the diode will activate and absorb the energy, thus protecting the device from damage.

SMB8J30CA-M3/5B is a robust device that offers good performances in high frequency and high transient voltage applications. It is designed for applications in which high-speed data transmission and high levels of protection are required. The low capacitance and quick response time of the device make it a great choice for high-speed interfaces, including LVDS, USB, Ethernet, and HDMI.

In summary, SMB8J30CA-M3/5B is a great choice for overvoltage protection applications. The device provides robust protection against high-frequency transients, electrostatic discharge, power supply overvoltage, and voltage surges. It is suitable for a wide range of applications, including automotive electronics, consumer electronics, industrial electronics, telecom, IoT, and medical devices. The low capacitance and leakage current make it an excellent choice for high-speed data transmission applications.
