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 ka SFP optical module, nā lako OLT, Ethernet switch a me nā huahana pūnaewele ʻē aʻe, hoʻohana pinepine ʻia lākou e like me nā mea pale e pale aku ai 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) Haʻihaʻi liʻiliʻi liʻiliʻi kaʻe uila (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, module optical communication, module fiber optical, sfp optical module, olt equipment, Ethernet switch, computer system, communication equipment, AC/DC power supply, automobile, electronic ballast, home appliances, instruments (watt hour meter), RS232/422/ 423/485, I/O, LAN, ISDN, ADSL, USB, MP3, PDAS, GPS, CDMA, GSM, pale pahupaʻikiʻi kikohoʻe, ʻano maʻamau/ʻokoʻa ka pale ʻana Hoʻohui ʻia ʻo RF / IC ka loaʻa ʻana o ka pale, ka hoʻopaʻa ʻana i ke keakea electromagnetic kaʻa, leo. / hoʻokomo wikiō, sensor/transmission, kaapuni hoʻomalu ʻoihana, relay, hoʻopaʻa leo leo contactor, a me nā māla 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 i 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, module optical communication, module fiber optical, sfp optical module, olt equipment, Ethernet switch and other network tools.Inā makemake ʻoe, hiki iā ʻoe ke loaʻa ka ʻike hohonu.
