Description
This is -50V, -3A, PNP Epitaxial Planar Silicon Transistor.
A PNP transistor is a type of bipolar junction transistor (BJT) that has a “positive-negative-positive” (PNP) configuration.
The term “PNP” refers to the polarities of the three regions in the transistor: the P-type base, the N-type collector, and the P-type emitter.
Features
1. Adoption of FBET, MBIT processes.
2. Low saturation voltage.
3. Large current capacity and wide ASO.
