Transient Voltage Suppressors (TVSs) are a type of diode used to protect electrical and electronic systems from short duration induced voltages, such as those caused by electrostatic discharge (ESD). TVS diodes offer a higher level of protection than traditional diode designs, and are suited to many applications in today’s electronics.

The SA78CAHE3/73 is a TVS diode designed to protect systems from high voltage transients. This device provides ESD protection for 1 and 2 ports while also offering an excellent peak pulse power of 3kW (10/1000μs). The SA78CAHE3/73 offers a low capacitance of 0.15pF and a low breakdown voltage of 1.5V. It is manufactured using a planar geometry, making it highly reliable and suitable for use in many environments.

The SA78CAHE3/73 is well-suited for applications where ESD protection is a priority. This diode can be used in automotive, aerospace, and industrial systems, as well as consumer electronics. It is also ideal for use in high-speed signal lines, such as USB and Ethernet. The device is also RoHS compliant, and is suitable for use in a variety of temperature ranges.

The working principle of the SA78CAHE3/73 is relatively simple. When the diode is exposed to a transient voltage, it will activate and “clamp” the voltage to a predetermined level. This level is determined by the breakdown voltage of the device (1.5V in this case). The device then acts as a barrier, preventing the voltage from reaching the circuit it is protecting.

The SA78CAHE3/73 is a reliable and effective diode for providing ESD protection. The small size of the device allows it to be used in a variety of applications, while its planar geometry ensures its reliability in harsh environments. With its low capacitance and breakdown voltage, and its high peak pulse power rating, the SA78CAHE3/73 is an excellent choice for protecting electronic and electrical systems from transient voltages.
