hoʻolauna pōkole

ʻO ka diode kahi mea hana me nā uila ʻelua, kahi hui PN i haku ʻia i kahi semiconductor P-type a me kahi ʻano semiconductor N-hiki i kēia manawa ke kahe wale mai loko mai o ke anode o ka diode a kahe i waho o ka cathode.

Nā ʻano maikaʻi

I ke kaapuni, hoʻopili ka cathode o ka diode i ka hopena uila haʻahaʻa, a pili ka anode i ka hopena uila kiʻekiʻe. I kēia manawa, e huli ʻia ke diode. Kāhea ʻia kēia moku i mua he bias. Ke liʻiliʻi loa ka ʻokoʻa uila ma waena o nā wēlau o ka diode, ʻaʻole hiki ke hoʻohuli i ka diode. Ma muli o ka liʻiliʻi o kēia manawa ma o ka diode. Aia wale a hōʻea ka uila i mua o ka diode i kekahi waiwai (ʻo ka volter diode silicon 0.6V ka haʻahaʻa haʻahaʻa, ʻo 0.2V ka huli huli haʻahaʻa o ka germanium diode ʻo 0.2V) e huli piha ka diode. Hoʻololi ka uila ma nā wēlau ʻelua o ka diode ma hope o ka huli ʻana (ʻo ka diode silikone e pili ana i 0.7V, ʻo ka diode germanium e pili ana i 0.3V).

Nā ʻano huli hoʻohuli

I ke kaapuni, ke pili ka cathode o ka diode i ka hopena uila kiʻekiʻe, a pili ka anode i ka hopena uila haʻahaʻa, aia ke diode i ka moku oki i kēia manawa a ʻaʻohe kahe o kēia manawa. Kapa ʻia kēia mokuʻāina ʻo bias bias. Ke huli ke diode i ke kipi hope, inā aia kekahi kahe nāwaliwali e kahe ana i loko o ke diode, ʻo kēia ka moku kulu. Ke piʻi ka volta huli ma waena o ka diode maʻamau i kekahi waiwai, e piʻi nui ka ʻaoʻao hoʻi i kēia manawa.
