has gloss | eng: TO-3 or "metal can" is a package type commonly used for very large transistors, silicon-controlled rectifiers, and, occasionally, integrated circuits. The component is mounted on a metal plate with a metal can crimped on top of it, providing good heat conduction and durability. TO-3 packages usually have three leads, though devices with four leads exist and more leads are possible. The leads pass through the metal plate and a glass seal, except for one lead which is usually attached to the case itself. They have two tabs with holes for mounting to a heatsink. Other packages tend to be used instead for newer designs, such as the TO-220 or the D2PAK which have similar thermal resistances but have a smaller footprint. The TO-3 design originated at Motorola around 1955, the lead spacing was originally intended to allow plugging the device into a then-common tube socket. |

has gloss | ind: TO-3 atau "metal can" (kaleng logam) adalah sebuah tipe kemasan yang sering digunakan pada transistor daya-tinggi, SCR dan kadang-kadang juga sirkuit terpadu. Kepingan komponen dipasang pada pelat logam dan sebuah "kaleng" pelindung logam dipasang diatasnya, memberikan hantaran bahang dan keawetan yang baik. Kemasan TO-3 biasanya mempunyai tiga saluran, walaupun begitu kemasan lebih dari empat saluran atau lebih mungkin untuk dibuat. Saluran-saluran menembus pelat logam melalui sebuah segel gelas, kecuali satu saluran yang biasanya disambungkan ke pelat logam. Pelatnya mempunyai dua lubang untuk pemasangan pada benaman bahang. |

has gloss | ita: Il TO3 (o meglio TO-3 ) è il nome di un contenitore usato per transistor e circuiti integrati definito dallo standard JEDEC. Questo contenitore (in inglese package) completamente metallico è costituito da una base piatta di forma romboidale con vertici smussati su cui è saldato un corpo cilindrico metallico di altezza contenuta. I vertici opposti più distanti sono forati e formano due flangie che ne permettono il fissaggio ad un dissipatore con due viti. Il TO-3 può essere realizzato in acciaio o alluminio . |
