Description
This is 800V, 10A, Silicon NPN Power Transistor.
C4237 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.
Features
1. With TO-247 package
2. Switching power transistor
3. High breakdown voltage
