Nā hiʻohiʻona noiʻi o ka TVS transient voltage suppression diode principle TVS transistor

TVS - Pōkole no ka Diode Kuʻe Voltage Suppressor. ʻO ke TV kahi mea hoʻopololei e kaupalena ana i ka overvoltage ma ke ʻano o kahi diode. Ke hoʻololi ʻia nā pou ʻelua o ka TVS i nā haʻalulu kiʻekiʻe o ka ikehu transient, hiki iā ia ke hoʻololi i ka impedance kiʻekiʻe ma waena o nā pou ʻelua i ka haʻahaʻa haʻahaʻa i ka wikiwiki o 10-12 kekona, e hoʻomoʻa i nā kilowatts o ka mana piʻi, a hoʻopaʻa i ka Volta ma waena o nā pou ʻelua ma kahi waiwai i koho mua ʻia, me ka pale pono ʻana i nā ʻāpana kikoʻī i nā kaapuni uila mai ka pōʻino i hoʻokumu ʻia e nā pulse surge. I ka hoʻolālā ʻana o SFP optical module,OLTmea lako, Ethernethoʻololia me nā huahana pūnaewele ʻē aʻe, hoʻohana pinepine ʻia lākou e like me nā mea pale no ka pale ʻana i nā huahana a hoʻopaʻa i ka uila static.
Nā hiʻohiʻona:
(1) wikiwiki pane wikiwiki (1ps);
(2) Ka mana kūwaho kiʻekiʻe;
(3) Haʻahaʻa leakage au;
(4) Liʻiliʻi hoʻohaʻahaʻa puʻe uila deviation (5%);
(5) ikaika clamping hiki, etc;
(6) ʻO ka hiki ke pale i ka piʻi ʻana a me ka hoʻopaʻa ʻana i ka uila.
Hoʻohana nui ʻia lākou i ka naʻauaoonu.oltmea lako, Ethernethoʻololi, ʻōnaehana kamepiula, lako kamaʻilio, lako mana AC/DC, kaʻa, ballast uila, nā mea hana hale, nā mea kani (watt hour meter), RS232/422/423/485, I/O, LAN, ISDN, ADSL, USB, MP3, PDAS, GPS, CDMA, GSM, pale kikohoʻe pahupaʻiwikiō, mode maʻamau / ʻokoʻa ʻano pale RF hui / IC kaʻa e loaʻa ai ka pale, kaʻa uila electromagnetic hoʻopiʻi ʻana, hoʻokomo leo / wikiō, sensor / hoʻouna, kaʻapuni mana ʻenehana, relay, hoʻopaʻa leo leo, a me nā kula ʻē aʻe. Ma ka māhele, hiki ke hoʻokaʻawale ʻia i ʻelua mau ʻāpana:
(1) Wahi a ka polarity, hiki ke hoʻokaʻawale ʻia i ʻekolu mau ʻano: unipolar a me bipolar;
(2) E like me ke kumu: hiki ke hoʻokaʻawale ʻia i nā mea hana maʻamau i kūpono no nā kaapuni like ʻole a me nā mea hana kūikawā kūpono no nā kaapuni kūikawā. Eia kekahi laʻana, nā mea pale uila AC like ʻole, 4-20mA nā mea pale o kēia manawa, nā pale laina ʻikepili, nā pale kelepona coaxial, nā pale kelepona, etc.
(3) E like me ka hoʻopili a me ka hoʻolālā i loko, hiki ke hoʻokaʻawale ʻia i nā diodes alakaʻi axial, ʻelua mau laina TVS inline (kūpono no ka pale ʻana i nā laina lehulehu), ʻano patch, ʻano modular, a me ke ʻano modular kiʻekiʻe.
Hiki ke hoʻohui like ʻia ka TVS me ka laina a hiki ke hoʻohana ʻia no ka hoʻopau koke ʻana i ka piʻi ʻana. Ma lalo o nā kūlana hana maʻamau, hōʻike ʻo TVS i kahi kūlana impedance kiʻekiʻe i nā mea i pale ʻia, ʻaʻole ia e pili i ka hana maʻamau o ka laina. Ke ʻoi aku ka nui o ka puʻupuʻu overvoltage maʻamau i kona puʻupuʻu haʻihaʻi, hoʻololi ka TVS mai kahi kūlana impedance kiʻekiʻe i kahi kūlana impedance haʻahaʻa. Hāʻawi ʻia kahi ala haʻahaʻa haʻahaʻa e hoʻohuli i ke kahe koke e kahe ana i nā ʻāpana i pale ʻia i ka diode TVS, a hoʻokuʻu ʻia ke au o ka piʻi koke ʻana ma o ka paipu TVS, ʻoiai e kaupalena pono ana i ka uila i kahi pae palekana, Ke nalowale ka overvoltage abnormal, TVS hoʻi koke i ke kūlana kū'ē kiʻekiʻe.
ʻO ka mea ma luna nei kahi ʻike pōkole o TVS Transient Voltage Suppression Diode Principle a me Application Characteristics TVS Tube, hiki ke lilo i mea kuhikuhi no kēlā me kēia. Loaʻa i kā mākou hui kahi hui ʻenehana ikaika a hiki ke hāʻawi i nā lawelawe ʻenehana loea no nā mea kūʻai aku. I kēia manawa, loaʻa i kā mākou hui nā huahana like ʻole: naʻauaoonu.oltmea lako, Ethernethoʻololia me nā lako pūnaewele ʻē aʻe. Inā makemake ʻoe, hiki iā ʻoe ke loaʻa ka ʻike hohonu.
