Ubudlelwano phakathi kokupakishwa kwe-MOSFET namapharamitha, ungawakhetha kanjani ama-FET ngokupakishwa okufanele

①Ukufakwa kwe-plug-in: TO-3P, TO-247, TO-220, TO-220F, TO-251, TO-92;

②Uhlobo lokukhweza phezulu: TO-263, TO-252, SOP-8, SOT-23, DFN5*6, DFN3*3;

Amafomu okupakisha ahlukene, umkhawulo ohambisanayo wamanje, i-voltage kanye nomphumela wokushisa wokushisaI-MOSFETizohluka. Isingeniso esifushane simi kanje.

1. TO-3P/247

I-TO247 ingenye yamaphakheji amancane ohlaka asetshenziswa kakhulu kanye namaphakheji wokukhweza ngaphezulu. 247 inombolo ye-serial yezinga lephakheji.

Kokubili iphakheji ye-TO-247 kanye nephakheji ye-TO-3P inokukhipha amaphini angu-3. Ama-chips angenalutho ngaphakathi angafana ncamashi, ngakho-ke imisebenzi nokusebenza kuyafana. Ngokuvamile, ukuchithwa kokushisa nokuzinza kuthinteka kancane.

I-TO247 imvamisa iyiphakheji engafakwanga ngci. Amashubhu angu-TO-247 ngokuvamile asetshenziswa emandleni aphezulu. Uma isetshenziswa njengeshubhu lokushintsha, i-voltage yayo yokumelana ne-current izoba kukhudlwana. Kuyifomu lokupakisha elivame ukusetshenziswa lamandla kagesi aphakathi nendawo kanye nama-MOSFET amanje. Umkhiqizo unezici zokumelana ne-voltage ephezulu kanye nokumelana nokuwohloka okuqinile, futhi kufanelekile ukusetshenziswa ezindaweni ezine-voltage ephakathi nendawo enkulu (okwamanje ngaphezu kuka-10A, inani lokumelana ne-voltage elingaphansi kuka-100V) ngaphezu kuka-120A, kanye nenani lokumelana ne-voltage elingaphezu kuka-200V.

2. TO-220/220F

Ukubukeka kwalezi zitayela zephakheji ezimbili zeAma-MOSFETiyafana futhi ingasetshenziswa ngokushintshana. Kodwa-ke, i-TO-220 inomshini wokushisa ngemuva, futhi umphumela wayo wokushisa ukushisa ungcono kunalowo we-TO-220F, futhi intengo ibiza kakhulu. Le mikhiqizo emibili yamaphakeji ilungele ukusetshenziswa ku-medium-voltage kanye nezinhlelo zokusebenza zamanje ezingaphansi kuka-120A kanye nezicelo ezinamandla kakhulu neziphezulu zamanje ezingaphansi kuka-20A.

3. KUYA-251

Lo mkhiqizo wokupakisha usetshenziselwa kakhulu ukunciphisa izindleko nokunciphisa usayizi womkhiqizo. Isetshenziswa kakhulu ezindaweni ezinama-voltage aphakathi nendawo kanye namandla aphezulu angaphansi kuka-60A kanye ne-voltage ephezulu engaphansi kuka-7N.

4. UKUZE-92

Le phakheji isetshenziselwa kuphela i-low-voltage MOSFET (okwamanje ingaphansi kuka-10A, imelana ne-voltage engaphansi kuka-60V) kanye ne-high-voltage 1N60/65, ikakhulukazi ukunciphisa izindleko.

5. UKUZE-263

Kungokuhlukile kwe-TO-220. Ngokuyinhloko yakhelwe ukuthuthukisa ukusebenza kahle kokukhiqiza kanye nokuchithwa kokushisa. Isekela izinga eliphezulu kakhulu lamanje kanye ne-voltage. Kuvame kakhulu kuma-MOSFET aphakathi naphakathi nephezulu angaphansi kuka-150A nangaphezulu kuka-30V.

6. KUYA-252

Ingenye yamaphakheji ajwayelekile amanje futhi ifanele izindawo lapho amandla kagesi aphezulu engaphansi kuka-7N kanye ne-medium voltage ingaphansi kuka-70A.

7. SOP-8

Le phakheji futhi yakhelwe ukwehlisa izindleko futhi ngokuvamile ivame kakhulu ku-medium voltage MOSFETs ngaphansi kuka-50A kanye ne-voltage ephansi.Ama-MOSFETcishe 60v.

8. SOT-23

Ilungele ukusetshenziswa endaweni enedijithi eyodwa yamanje kanye ne-voltage engu-60V nangaphansi. Ihlukaniswe yaba izinhlobo ezimbili: ivolumu enkulu kanye nevolumu encane. Umehluko omkhulu utholakala kumanani ahlukene amanje.

Okungenhla kuyindlela elula yokupakisha ye-MOSFET.
