J6820 is NPN Triple Diffused Planar Silicon 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.
