Understand the difference.
Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.
NPN
SymbolsNPN bipolar transistor
A bipolar transistor with base, collector and emitter terminals arranged for NPN operation.

- Schematic
- Application
- Electronic components
- Reference family
- Manufacturer
A distinction that matters
The emitter arrow distinguishes NPN from PNP in common schematics; the package pin order must still come from the selected part.
PNP
SymbolsPNP bipolar transistor
A bipolar transistor with base, collector and emitter terminals arranged for PNP operation.
- Drawing use
- Schematic
- Application
- Electronic components
- Reference family
- Manufacturer
A distinction that matters
PNP polarity differs from NPN; mirrored graphics do not change a transistor's type or package pin assignment.
