TVS diodes are widely used in many applications, especially in transient voltage surge suppressor (TVS) and other power applications. The 1SMC75TR13 is a popular power transient voltage suppressor diode, commonly used for a variety of applications such as protecting sensitive electronic equipment from destructive voltage spikes caused by lightning or other electrical transient events. In this article, we will discuss the 1SMC75A TR13 application field and working principle.

1SMC75A TR13 Application Field

1SMC75A TR13 is a power transient voltage suppressor diode. It is mainly used in application fields such as automotive (powertrain control module, airbag, .etc), consumer electronics (docking stations, gaming consoles, and power supplies), and industrial (medical, set-top box, etc).

In automotive applications, the 1SMC75A TR13 can protect the powertrain control module (PCM) and airbag systems against transient voltage surges that can cause permanent damage or smoke. In the consumer electronics field, 1SMC75A TR13 has been used to protect devices like gaming consoles, docking stations, and power supplies. In the industrial field, it can protect sensitive electronic equipment from destructive voltage spikes caused by lightning or other power transient events.

1SMC75A TR13 Working Principle

1SMC75A TR13 works on the principle of avalanche breakdown. In avalanche breakdown, electrons in a reverse-biased PN junction are accelerated and collide with atoms in the depletion region. When the electric field reaches a certain threshold, the electrons gain enough energy to ionize the atoms, leading to an avalanche of electrons. This phenomenon is known as Zener breakdown, which is used to control the current flow in the diode.

1SMC75A TR13 has a built-in avalanche diode, which provides a reverse breakdown voltage of 70V and a current rating of 75A. It also has a low clamping voltage, which means it can protect against transient voltage surges up to 70V. This device also has a wide operating temperature range of -40°C up to +125°C.

1SMC75A TR13 is a high-performance, cost-effective solution for applications that require high surge protection. It can protect both automotive and consumer electronics from destructive transient voltage surges. It also has a wide operating temperature range, making it suitable for a variety of applications.
