B1182 is – 40V, – 2A, Medium power Transistor.

A PNP transistor is one of the semiconductor components used in electrical engineering and electronic circuit design, belonging to the Bipolar Junction Transistor (BJT) family. The PNP transistor consists of three layers of semiconductor material: P-type, N-type, and P-type, each with different charges. The name PNP transistor stands for “Positive-Negative-Positive,” reflecting the characteristics of these three semiconductor layers.

PNP transistors comprise the following key components:

1. Emitter: The emitter is the first layer and is made of P-type semiconductor material. The emitter serves as the primary source of current.

2. Base: The base is the second layer and is made of N-type semiconductor material. The base controls the current between the emitter and collector.

3. Collector: The collector is the third layer and is made of P-type semiconductor material. The collector collects the current, which flows from the emitter through the base.
