When it comes to TVS-Diodes, one of the most common applications is the 15KPA78CA-HR. This type of diode is used for protecting sensitive equipment from high voltage transients, such as those caused by electrical surges and lightning strikes. In order to understand how such a diode works, we must first understand its design and functionality.

The 15KPA78CA-HR is a bidirectional, high power clamp diode that utilizes an avalanche breakdown to suppress high voltage transients. It is a sensitive device that responds almost instantaneously to the presence of a high transient voltage, allowing it to provide fast and effective protection. The diode is designed to be placed across the power or signal line to be protected, with the power or signal line being connected to ground by means of a low impedance path. When the voltage rises beyond the breakdown capability of the diode it quickly begins suppressing the voltage by utilizing its avalanche breakdown characteristic. This causes the current to flow through the diode, clamping the voltage at the breakdown level. As a result, the voltage is clamped and the sensitive components downstream do not experience any over-voltage damage.

15KPA78CA-HR\'s are used in a variety of applications, including telecommunications, automotive, consumer electronics, and medical devices. They are designed to address a variety of applications and can handle various voltage transients up to 8,000 volts. Due to their low capacitance and fast response times, these diodes are ideal for sensitive applications that require both protection and fast response times. In addition, these diodes are 100% surge tested to insure that the highest levels of protection are provided.

In summary, the 15KPA78CA-HR is a high power, high voltage clamp diode that is ideal for protecting sensitive electronic components against high voltage transients. The diode utilizes an avalanche breakdown capability to quickly and effectively clamp the voltage, thus providing the fast protection needed in sensitive applications. The diode is versatile and can be used in a variety of applications, including telecommunications, automotive, consumer electronics, and medical devices. With its 100% surge tested capability and fast response times, the 15KPA78CA-HR is a great choice for protecting sensitive components against high voltage transients.
