TVS - Diodes

TVS (Transient Voltage Suppressor) diodes are an important component of many electronic circuits. These devices act as a semiconductor switch that limits the amount of peak voltage seen by a circuit. They can be used to protect against electrical surges, such as those caused by lightning strikes, and can also protect against power irregularities such as when the power line is switched off unexpectedly. The SA17HE3/54 TVS diode is a popular choice for many applications due to its fast, reliable protection. In this article, we will look at the application field and working principle of the SA17HE3/54 diode.

Application Field and Working Principle of SA17HE3/54 TVS Diode

The SA17HE3/54 TVS diode is an ideal choice for protecting applications such as LED lighting, power supplies, and high frequency circuits. This device has an operating voltage of 5V, and a peak pulse power rating of 400 W. In addition, it has a fast response time and can protect against surge voltages up to 750V, making it a great choice for a wide variety of applications.

The working principle of the SA17HE3/54 is quite simple. When the peak voltage in a circuit exceeds the specified level, the device will act as a semiconductor switch, limiting the amount of current that passes through the circuit. The device does this by clamping the peak voltage to a safe level. This prevents further damage to the circuit, and helps to maintain system reliability.
