In a PNP transistor, an increase in collector–base reverse bias causes a slight increase in collector current even when the emitter current is held constant. This occurs primarily because:
Hole mobility increases in the collector region
The collector resistance decreases due to depletion region expansion
The emitter injection efficiency decreases
The effective base width decreases with collector–base voltage
The emitter injection efficiency decreases
