It has been designed for surface mount applications and is suitable for use in high-voltage, high-frequency, high-temperature environments, such as automotive, consumer, and industrial sectors.

Key Features and Benefits

The 5KP14AHE3/73 has a low capacitance of 3.5pF and a low clamping voltage of 14.2V, making it ideal for unidirectional protection. It can also withstand IPP results up to 2.5kV, providing surge protection for your electronic devices, even under the most extreme conditions. In addition, it has an operating temperature range of -55°C to +150°C, making it a reliable choice for a wide range of applications.

Working Principle of the 5KP14AHE3/73

The 5KP14AHE3/73 consists of two p-n junction diodes in a back-to-back configuration. The device is designed such that when an input voltage rises above its breakdown voltage, it begins to conduct current, thus protecting the device from damaging voltage spikes. This process is known as "clamping voltage," as the voltage is held below its breakdown potential. The diode\'s capacitance helps to reduce inductive ringing, thus further protecting the device.
