SMDJ 16 A Application Field and Working Principle

The SMDJ16A type TVS (Transient Voltage Suppressor) Diode is widely used in various types of applications for its reliable and powerful performance. In the electronics industry, the device is employed in areas such as overvoltage or transient protection, landline communication networks, electronic control systems, automotive electronics, and other industrial power equipment. It has been successfully used in a great many applications due to its combination of superior speed, low leakage, high breakdown voltage and extremely low clamping voltage.When a TVS diode is in an open or unpopulated circuit, its breakdown voltage serves as an overvoltage protector, allowing only acceptable voltage to pass through the load. In a closed or populated circuit, the breakdown voltage serves as an open or unpopulated circuit, allowing for avoided generation of objectionable currents as well as a wide range of overcurrent protection.The SMDJ16A is a Double Side Bidirectional TVS Diode. It has an extremely low dynamic resistance when a TVS diode is mounted to a circuit board and is subject to transient surge voltage, the chip can react in a fraction of a second to reduce the voltage rise to a safe level. As the name suggests, the SMDJ16A is bidirectional, meaning it can provide protection from overvoltage or surge on both sides of the TVS diode. The SMDJ16A utilizes high voltage technology with a wide working range from 8 poles to 400 volts. The positive temperature coefficient provides for a low dynamic resistance. The SMDJ16A also features fast response time and thermal protection to automatically reset once the surge voltage has been removed from the circuit. It also offers excellent electrical and mechanical reliability as well as excellent long-term stability. The SMDJ16A also features low thermal impedance, small size and fast response time, which makes it ideal for various applications where there is the risk of high voltages and surges. The device is available in various packages and is suitable for use in high temperature, high moisture and damp environment applications. It is also used when the requirement of high reliability and safety is in place. The SMDJ16A also has a wide operating temperature and excellent surge current handling capability. This device provides a high level of ESD (ElectroStatic Discharge) protection. In a worst case scenario, a single SMDJ16A can be employed to shut down an entire electronics device, providing short circuit protection. The device also offers excellent thermal and current transfer characteristics, allowing for optimal performance and reliability.All in all, the SMDJ16A is a reliable, high-performance TVS diode, which is highly suitable for applications that need to provide protection from overvoltage, surges and transients. It is widely used in a variety of applications such as landline telephone networks, automotive electronics, industrial power equipment and electronic control systems. Thanks to its high performance and reliability, it is trusted by manufacturers all over the world.
