TVS (Transient Voltage Suppressor) diodes, also known as surge suppressor diodes, are specialized power diodes designed to protect electrical circuits from temporary, or transient high-voltage surges. They form an important part of a circuit’s protection system. The PESD15VS2UT,215 is one of the most popular TVS diodes used today because of its low capacitance and wide voltage range. In this article, we will discuss the application field and working principle of the PESD15VS2UT,215.

The PESD15VS2UT,215 TVS diode can handle a maximum non-repetitive power dissipation of 150W and offers an excellent breakdown voltage of 15V. This device can easily suppress ESD pulse voltages up to 22kV and its bidirectional ESD protection capability makes it ideal for use in a variety of applications. Some of these applications include telecom equipment, computers and peripherals, consumer appliances, audio and video equipment, automotive, and medical devices.

In addition, the low capacitance of the device – 30pF - ensures low signal distortion. The PESD15VS2UT,215 also has a wide range of operating temperatures, from -65°C to +150°C. This makes it suitable for use in extreme temperature environments.

So how does the PESD15VS2UT,215 TVS diode work? When a positive surge voltage is applied to the diode, the region near the PN junction is quickly depleted of electrons. This creates an electric field which prevents negative charges from entering the PN junction. When the surge voltage is reduced, the electric field also disappears and the electrons move back to the PN junction.

When a negative surge voltage is applied, the same process happens but with the opposite charges. The electric field created by the PN junction prevents positive charges from entering the junction. When the surge voltage is reduced, the electric field also disappears and the positive charges move back to the PN junction.

The PESD15VS2UT,215 is an efficient TVS diode with a wide range of applications. Its high surge protection capabilities make it ideal for use in a variety of electrical circuits. In addition, its low capacitance ensures low signal distortion while its wide range of operating temperatures make it suitable for use in extreme temperature environments.
