TVS (Transient Voltage Suppressor) diodes, such as SA17-E3/73, are designed to protect electrical and electronic systems from voltage transients induced by lightnings, inductive loads, or switching circuits. They play a vital role in protecting the systems they are connected to from voltage spikes and other high-voltage damage. TVS diodes are semiconductors that can be used in place of traditional Zener diodes. TVS devices have a much faster response time than Zener diodes, which makes them much better suited for protecting against voltage transients.

SA17-E3/73 is an unidirectional TVS diode which is widely used to protect sensitive and expensive electronic equipment from voltage transients. This device is capable of withstanding power going both ways. It has a high peak pulse power rating of 1500W and can operate within a voltage range of 5.0 V to 170 V. It comes in a compact package, making it an ideal choice for use in circuit protection applications with limited physical space.

The working principle of the SA17-E3/73 is based on a P-N junction. In normal operation, current flows through the device in a single direction, which is determined by the polarity of the voltage applied. Upon encountering a transient voltage, the current through the P-N junction exceeds the reverse breakdown voltage of the device and causes electrons to avalanche. This avalanche action increases the current and the voltage quickly to a level that will support the surge current. This forms a current path through the device for the transient energy.

The applications of the SA17-E3/73 include Automotive and Industrial Equipment, Data Communications, Computers, Power Supplies, Handheld Electronics, and Telecom/Networking devices. It is used to protect sensitive and expensive equipment from transient voltage caused by lightning, switching circuits, or inductive loads.

The SA17-E3/73 can be used in a variety of applications such as automotive, industrial, and power supplies. It is an ideal device for protection against voltage transients in systems with limited physical space. Its fast response time and high peak power handling capability make it a reliable device for protecting electrical and electronic equipment from voltage spikes.
