TVS - Diodes refer to the specialized semiconductor diodes that provide surge-protection services to sensitive electronic equipment. A typical TVS - Diodes’ configuration includes a surface-mount diode and a pair of parallel anode and cathode electrodes. It also provides an extremely fast-responding protection element which reacts to surge and transient voltage in just nanoseconds.The SA70CA-E3/73, also known as the transient voltage suppression diode, is a popular TVS - Diodes widely used in surge current protection. The cathode and anode of this diode series boast a stand-off voltage range up to 73 V and the devices also have low clamping voltage and soft reverse recovery characteristics.

The basic working principle of this TVS - Diodes is to shunt sudden spikes of energy in a circuit, acting like a surge protector. This protects the sensitive electrical devices from overvoltage damage. It monitors either the anode or the cathode for surge current. If a potential surge voltage occurs, the diode will conduct. As the surge current flows through it, the diode clamps the voltage at a specified level, thus protecting against a reverse voltage of up to 73V.The SA70CA-E3/73 diodes are vastly used in automotive applications, consumer electronics, military electronics, and power supplies. They can be used for overvoltage protection, ESD protection, pulse noise suppression, and line protection. In automotive electronics, they are generally used for protecting automobile ECUs, meters, and entire circuits from degradation due to transients or EMI.In consumer electronics, these diodes can protect consumer televisions, computers, modems, routers and home appliances from damage due to voltage transients. This is because the time constant of TVS - Diodes is significantly shorter than that of varistors. In applications such as LCD TV monitors, a TVS - Diode may even be connected directly parallel to a LCD module.The SA70CA-E3/73 from Littelfuse represent an advancement in ESD and transient protection solutions, enhancing protection performance for sensitive automotive applications. The key advantages of these high-quality TVS - Diodes include fast response time, low capacitance, high surge current handling capability, low leakage current, and enhanced safety-ground measures. Furthermore, these TVS - Diodes are RoHS Compliant.
