The Main Classification Of Transistors

Material

According to the semiconductor materials used in transistors, it can be divided into silicon material transistors and germanium material transistors. According to the polarity of the transistor, it can be divided into germanium NPN transistor, germanium PNP transistor, silicon NPN transistor and silicon PNP transistor.

craft

Transistors can be divided into diffused transistors, alloy transistors and planar transistors according to their structure and manufacturing process.

Current capacity

Transistors can be divided into low-power transistors, medium-power transistors and high-power transistors according to their current capacity.

working frequency

Transistors can be divided into low-frequency transistors, high-frequency transistors and ultra-high-frequency transistors according to the operating frequency.

Package structure

According to the package structure, transistors can be divided into metal package (referred to as gold seal) transistors, plastic package (referred to as plastic package) transistors, glass shell package (referred to as glass package) transistors, surface package (chip) transistors and ceramic package transistors. Its package shape is varied.

By function and purpose

Transistors can be divided into low noise amplifier transistors, medium and high frequency amplifier transistors, low frequency amplifier transistors, switching transistors, Darlington transistors, high reverse voltage transistors, band-stop transistors, band-damping transistors, microwave transistors, phototransistors and magnetic transistors according to their functions and uses. Various types of transistors.
