TVS-Diodes: 3.0SMCJ20A-13 Application Field And Working PrincipleThe 3.0SMCJ20A-13 is a transient voltage suppressor diode (TVS), a type of semiconductor device designed to protect sensitive electronic components from damage due to electrical surges. With its low capacitance, high surge capability, and 5000W surge power capability, the 3.0SMCJ20A-13 is an ideal choice for suppressing spikes and providing over-voltage protection for a variety of electronics applications.The 3.0SMCJ20A-13 is designed to protect from fast-rising transient voltage phenomena up to 200v. Its low capacitance and high-surge capability make it ideal for protecting against spikes and providing over-voltage protection in power distribution systems, data and signal lines, telecommunication systems, medical and industrial equipment, and automotive applications.The 3.0SMCJ20A-13 is designed with a mechanism to absorb high levels of energy in an extremely short time, preventing it from damaging the electronic components connected to it. The TVS diode works by quickly limiting the rise time of a surge and quickly “dumping” it. Its small form factor and low profile make it suitable for many electronic systems and cases, such as telecommunications infrastructure, Internet of Things (IoT) devices, and other commercial or industrial applications.Working Principle:The 3.0SMCJ20A-13 is designed so that if an electrical surge exceeds the specified maximum, then the TVS diode is triggered and the surge is “dumped” into a safe resistance. This process allows the device to absorb and dissipate destructive energy produced by electrical surges. The TVS diode will then return to its normal operating state.The 3.0SMCJ20A-13\'s effective working principle is a combination of the avalanche breakdown effect and the well-known Zener-effect. When a surge voltage is applied to the diode, the avalanche breakdown occurs, with the majority charge carriers (electrons and holes) being generated close to the p-n junction. The Zener effect then has a breakdown voltage, which is equal to the reverse breakdown voltage at the diode’s junction. This then enables the rapid dissipation of excess energy from the device.When the surge voltage exceeds the specified maximum, the Zener effect of the diode causes it to break down, dissipating the surplus energy into a safe resistance. The TVS diode then quickly returns to its normal operating state, providing protection for the connected electronics from further surges.The 3.0SMCJ20A-13 is one of the most reliable and efficient TVS diodes available on the market. It has a wide range of uses and offers excellent surge protection. Its high surge capability, low capacitance, and small form factor sti stand it apart from other TVS diodes. The 3.0SMCJ20A-13 can provide reliable protection for a variety of sensitive electronics in industrial, commercial, and consumer applications.
