What is transistor outline package?
The Transistor Outline (TO) package is an industrial standard that regulates the design and size of current-conducting microelectronic packaging and housings consisting of a TO header and a TO cap.
Which packaging material have the standard family of transistor outline to?
The TO-220 is a style of electronic package used for high-powered, through-hole components with 0.1 inches (2.54 mm) pin spacing. The “TO” designation stands for “transistor outline”. TO-220 packages have three leads.
What are the different IC packages?
What is IC packaging?
- DIP (Double In-line Package)
- SOP/SOIC/SO (Small Outline Package)
- QFP (Quad Flat Package)
- QFN/LCC (Quad Flat Non-leaded Package)
- BGA (Ball Grid Array Package)
- CSP (Chip Scale Package)
What is TO3 package?
TO-3 Package. The TO-3 or TO3 is a type of ‘metal can’ package that is capable of high-power dissipation commonly used by power transistors, SCR’s and other high-power semiconductor devices. The TO-3 is made entirely of metal, with the microchip mounted on its metal can base and then covered with a metal cap .
What are to packages?
TO packages consist of a TO header and a TO cap. While the TO header forms the basis of the encapsulated components and provides them with power, the cap enables smooth optical signal transmission. These two components form a hermetically sealed package that protects sensitive semiconductor components.
What is DIP package electronics?
In microelectronics, a dual in-line package (DIP or DIL), is an electronic component package with a rectangular housing and two parallel rows of electrical connecting pins. The package may be through-hole mounted to a printed circuit board (PCB) or inserted in a socket.
What is the most commonly used integrated circuit packaging material?
Lead frames are the most common IC packages. You would use these packages for wire-bond interconnected dies, with a silver or gold-plated finish. For surface-mount plastic packages, manufacturers often use copper lead-frame materials.
What are the three basic types of linear IC packages?
IC packages can be grouped into three general categories; Dual In-line Packages, Chip Carriers and Grid Arrays. All the packages, regardless of the category has a body style that scales with pin count.
What are the other three most common types of packages?
There are three major types of paper packaging: corrugated boxes, boxboard or paperboard cartons, and paper bags and sacks.
What is 2N3055 transistor?
The 2N3055 is a silicon NPN power transistor intended for general purpose applications. It was introduced in the early 1960s by RCA using a hometaxial power transistor process, transitioned to an epitaxial base in the mid-1970s. Its numbering follows the JEDEC standard. It is a transistor type of enduring popularity.
What is a to3 transistor?
In electronics, TO-3 is a designation for a standardized metal semiconductor package used for power semiconductors, including transistors, silicon controlled rectifiers, and, integrated circuits. TO stands for “Transistor Outline” and relates to a series of technical drawings produced by JEDEC.
What is package example?
A package is an organized collection of classes which is included in the program as per the requirement of the program. For example java.io package is included for input and output operations in a program.

What is the package name for a transistor?
Most of the packaged transistor is grouped with the term TO (Transistor Outline). Picture below is a transistor package which we use in the electronics world, including TO-92a, TO-92B, TO92C, TO-126, TO-220, TO-18, TO-39, TO-3, and TO-3P (N), following the legs or the terminal base, emitter, and collector.
What kind of transistor is in a to 3 case?
The picture to the left shows a military JAN qualified 2N5302 transistor, while the picture below shows a commercial 2N3055 transistor in a TO-3 package. This is a through-hole device also called a TO-204, and is similar to a TO-23 package, but having different physical dimensions.
What is a case Mount for a transistor?
This is a through-hole device also called a TO-204, and is similar to a TO-23 package, but having different physical dimensions. Case mount. A type of package which provides a method of readily attaching one surface of the semiconductor device to a heat dissipater to achieve thermal management of the case temperature.
