Transient Voltage Suppressor diodes (TVS diodes) provide a critical protection function to vital components in electronic applications. This is made possible by quickly reacting to incoming transients, transient pulses, and other forms of electrical overstress and dissipating them in the form of heat. The SMBJ16CA-QH is a ferrite-basedTVS diode with a strong voltage and current rating and low capacitance. It has many applications, and this article will discuss its use in further detail.

The SMBJ16CA-QH is a 1500W unidirectional TVS diode used for protecting components from large transients, and it features an ultra-low capacitance of 0.7pF to minimize the effect on signal integrity. With a reverse voltage rating of 16V and a surge current rating of 65A, the SMBJ16CA-QH is a robust diode that can handle a wide variety of applications. Additionally, it is fast responding with a response time of 8ns, which helps it react quickly to transients and other forms of overstress.

The SMBJ16CA-QH is applicable for many applications as it is widely used in automotive lighting applications, communication systems, consumer electronics, and industrial systems. This is due to its fast response time, voltage, and surge rating that is needed to handle high power levels in these applications. Furthermore, its small size and low profile makes it very versatile meaning it can easily be installed in various types of applications. Additionally, it has a low leakage and low capacitance which helps to reduce signal contamination and enhance signal integrity.

The SMBJ16CA-QH also features a robust and reliable construction with its glass-passivated transistor junction. This helps it withstand a wide range of environmental conditions, including temperature, humidity, and other volatile conditions. This also helps it operate safely within its operating temperature ranges and improves its overall reliability. The device also has a high insulation resistance which helps to protect it from external electrical noise. Additionally, it is designed to meet various standards such as RoHS, UL, and CSA.

The working principle of the SMBJ16CA-QH is based on the concept of reverse bias breakdown. When an overstress is applied to the diode, the depletion region between the junction’s p − type and n − type regions begins to widen. This creates an avalanche breakdown which causes the voltage to drop across the diode and for current to flow. As the current flows through the diode, it dissipates in the form of heat, which prevents it from reaching the protected component. The current then returns to its stable level when the overstress is dissipated, allowing the diode to remain in its normal state.

The SMBJ16CA-QH is a highly reliable and efficient TVS diode that provides a critical protecting function to components against transients and other forms of overstress. It is applicable for many applications, including those with high power and signal integrity requirements. Additionally, its small size and low profile with fast acting response help it deal with a range of external environmental conditions quickly and effectively. Its working principle is based on reverse bias breakdown, which allows it dissipate incoming overstresses in the form of heat and helps prevent it from reaching other components.
