Varactor diode, also known as a capacitive diode, is a special type of diode that has the characteristic of variable capacitance. Its working principle is based on the reverse bias of the PN junction, which changes the capacitance value by altering the reverse voltage. Varactor diodes are widely used in fields such as RF circuits, oscillators, filters, etc. Their functions and characteristics are as follows
Crystal transistor, also known as bipolar transistor, abbreviated as transistor. The transistor has the function of current amplification and is the core device for signal amplification and processing, widely used in electronic products.

Bipolar Junction Transistors (BJTs) are essential semiconductor devices widely used in amplification, switching, and signal processing. As a professional manufacturer, YFW Microelectronics excels in producing high-performance BJTs, catering to automotive, industrial, and consumer electronics sectors. Understanding their structure and types is key to leveraging their functionality effectively.
There are two types of transistors based on their materials: storage transistors and silicon transistors. And each of them has two structural forms, NPN and PnP, but the most commonly used are silicon NPN and PnP transistors. Except for the power polarity, their working principles are the same. The following only introduces the current amplification principle of NPN silicon transistors.
