Working Principle

The BB202,135 Varicap Device is a semiconductor device with two terminals and a variable capacitance. The capacitance of the device is controlled by an applied reverse voltage. When the applied voltage is increased, the capacitance of the device decreases. Conversely, when the applied voltage is decreased, the capacitance of the device increases. This ability to control the capacitance of the device with an applied voltage makes the BB202,135 ideal for use in applications where adjustable capacitance is needed.The device consists of a semiconductor substrate with a dielectric layer above it. The dielectric layer consists of two electrodes which act as the terminals of the device. An external voltage is connected to one terminal, known as the anode, and the other terminal, known as the cathode, is left unconnected. The reverse voltage applied to the anode causes the capacitance of the device to change.The BB202,135 Varicap Device is a versatile semiconductor device which can be used in a variety of electronic circuitry applications. It has application fields in radiofrequency tuning, signal filtering, and voltage regulation applications. Additionally, its working principle of adjusting the capacitance through application of a reverse voltage makes it ideal for applications where adjustable capacitance is necessary.
