SD175SA30A Transient Voltage Suppressor (TVS) diode is a member of single rectifier diodes which are used to protect electric components from high voltage transients. It has passive electronic components embedded in a semiconductor substrate, making it less affected by ongoing circuit failures such as shorts. The diode includes an anode (positive terminal) and a cathode (negative terminal). Its forward voltage ranges from 15V to 175V with a peak power dissipation of 300W.
SD175SA30A.T application field is mainly for automotive electronics. It can protect sensitive automotive electronics from damage caused by transient voltage sources such as ESD or EMI. It is also used in telecommunications, power supplies, computers, control systems, and other electronic equipment which would require protection from voltage spike.
In order to understand its working principle, we first consider the basic structure of the SD175SA30A.T. It consists of a lightly doped P-region, an N-region, and a heavily doped P+ region connected in series. The P-region serves as the LED\'s anode, and the N-region is the LED\'s cathode. When a voltage is applied to the LED, the electrons are attracted to the anode and travel through the P-region in the form of a current. The electrons then reach the N-region, and are repelled back to the anode by the repulsive force of the negative charge in the N-region. This cycle of electron movement is what allows current to flow through the LED, thus creating light.
The SD175SA30A.T is used to protect sensitive electronic components such as integrated circuits and Printed Circuit Boards (PCB) from transient voltage sources. It works by clamping a voltage spike at a safe level and shunting the spike’s current away from the protected circuit. When a voltage transient is detected, the diode will conduct current in the reverse direction, thus acting as an effective short circuit. In this way, the SD175SA30A.T will effectively protect the circuit it is connected to, while also dissipating the excess energy in the spike.
The SD175SA30A.T is an effective single rectifier diode for the protection of automotive electronics from high voltage transients. It works by clamping a voltage spike at a safe level and shunting current away from the protected circuit. As such, it can help protect sensitive components from damage caused by voltage spikes and other transient sources such as ESD and EMI. It is also suitable for use in other applications such as telecommunications, power supplies, control systems, and computers.
