TIP120 is 60V, 5A, Silicon NPN Transistor.

A Silicon NPN Epitaxial Planar Transistor is a type of bipolar junction transistor (BJT) made from silicon, a semiconductor material. This transistor is designed for amplifying or switching electronic signals in various electronic circuits.

NPN Configuration:

1. Emitter (N): The heavily doped N-type layer, which is the source of charge carriers (electrons) in the transistor.

2. Base (P): The thin P-type layer, which controls the flow of charge carriers between the emitter and collector.

3. Collector (N): The N-type layer, which collects the charge carriers that pass through the base-emitter junction.



1. Medium Power Complementary silicon transistor

2. TIP120, TIP121, TIP122 Darlington TRANSISTOR (NPN)

3. TIP125, TIP126, TIP127 Darlington TRANSISTOR (PNP)
