TVS (Transient Voltage Suppressor) diode is a form of transient voltage protection circuit, commonly used to protect sensitive electrical components from transient voltages. It is a high power, fast acting surge protection, designed to protect both low and high voltage lines from damaging transients. The SMB8J15CHE3/5B series TVS diode is an advanced, low-capacitance, high-power product designed for high-speed data and signal protection applications.

The SMB8J15CHE3/5B series TVS diode is widely used in telecom, high-speed data and industrial applications. It is used in many types of industrial electronics such as power supplies, motor controls and other electrical and electronic equipment. The device is able to withstand over-voltage transients up to 15,000 volts and can protect against false triggering from induced lightning surges. It is designed to operate efficiently in temperatures ranging from -40°C to +125°C.

The working principle of the TVS diode is based on the principle of avalanche breakdown. When the applied voltage reaches a certain threshold, the thin PN junction of the diode breaks down resulting in the release of electrons, which then cross over the junction and provide signal protection. The released electrons create a wide conduction band which acts as the active region. This active region allows a large current to pass through the junction and dissipate the voltage signal. The avalanche junction is also designed to self-repair, so that the device can be used repeatedly without compromising its performance.

The SMB8J15CHE3/5B series TVS diode is able to provide protection from over-voltage transients and ESDs (electrostatic discharges), which can be caused by various external factors such as lightning, power surges or electrostatic discharge. The device also provides protection from false triggering from induced lightning surges. It is ideal for use in telecom applications, military systems, industrial electronics and automotive applications. The SMB8J15CHE3/5B series TVS diode is available in a variety of packages such as D2PAK, SOIC, SC-75 and M.2 packages. It is also RoHS compliant.

In conclusion, the SMB8J15CHE3/5B series TVS diode is an advanced, high-power, low-capacitance device designed for high-speed data and signal protection. It is widely used in telecom, industrial, and automotive applications to protect systems from over-voltage transients and ESDs. The device is able to withstand over-voltage transients up to 15,000 volts and is also designed to self-repair in order to ensure a reliable performance. The SMB8J15CHE3/5B series diode is available in a variety of packages, provides a wide operating temperature range, and is RoHS compliant.
