TVS - Diodes, otherwise known as transient voltage suppressors, are specialized diodes designed to protect a device by absorbing high-voltage electrical surges or spikes and converting them into a low-voltage electrical signal. The 15KPA20A-HR is a type of TVS diode that is used in applications in which the environment may experience sudden, unexpected power changes or failures, such as in automotive, industrial, or medical control systems.

The 15KPA20A-HR is composed of two separate parts: the suppression core and the clamp structure. The suppression core consists of a three-layer diode that is able to store and discharge high voltage pulses, preventing them from damaging the sensitive components of the device. The clamp structure consists of a pair of p-n junctions connected in series with a resistor that help regulate the voltage to protect the device.

The 15KPA20A-HR is able to protect against high-voltage surges up to 1,500W peak power dissipation and up to 20A peak current dissipation. It also has an operating temperature range of -55°C to 125°C (Tj), allowing it to be used in a variety of environments. In addition, it has an adjustable reverse breakdown voltage range between 12V-24V, making it ideal for controlling power flows in devices that may require different voltages.

The working principle of the 15KPA20A-HR is relatively simple. When a high-voltage pulse strikes the suppression core, the diode absorbs the energy and quickly discharges it to ground. At the same time, the clamp structure works to regulate the voltage to a safe, manageable level. This ensures that the device is protected from potentially harmful voltage surges.

The 15KPA20A-HR is an incredibly valuable tool for the protection of sensitive electronic equipment. It is an excellent choice for applications in environments with high levels of electrical surge or with fluctuating power supplies. With its adjustable voltage and temperature range, as well as its robust level of protection, the 15KPA20A-HR provides reliable protection for electronic equipment in a variety of environments.
