SpletIn the p-type region there are holes from the acceptor impurities and in the n-type region there are extra electrons.: When a p-n junction is formed, some of the electrons from the n-region which have reached the conduction band are free to diffuse across the junction and combine with holes.: Filling a hole makes a negative ion and leaves behind a positive ion … SpletA thyristor with a P-N-P-N structure has three junctions: PN, NP, and PN. If the anode is a positive terminal with respect to the cathode, the outer junctions, PN and PN are forward-biased, while the center NP junction is reverse-biased. Therefore, the NP junction blocks the flow of a positive current from the anode to cathode. radio yi durazno en vivo
