What is TO 5 package?
In electronics, TO-5 is a designation for a standardized metal semiconductor package used for transistors and some integrated circuits. The TO element stands for “transistor outline” and refers to a series of technical drawings produced by JEDEC.
What is a to package?
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 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 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.
What are the different types of IC packages?
The Common IC Packaging Types
- 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 metal can package?
TO-5 Package. The TO-5 is a type of ‘metal can’ package (also known as ‘metal header’ package) for semiconductor devices. It is hermetically sealed to protect the device from environmental factors such as contaminants and moisture.
What is package and packaging?
Packaging is all of the materials used to brace, contain, and protect a shipment. A package is the single sealed unit of the shipper carton that contains the shipment and the packaging used to protect it. Packaging is not quite the same as packing but the two do go hand in hand sometimes.
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 are IC packages made of?
The materials of the package are either plastic (thermoset or thermoplastic), metal (commonly Kovar) or ceramic. A common plastic used for this is epoxy-cresol-novolak (ECN). All three material types offer usable mechanical strength, moisture and heat resistance.
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.
Is the metal can a to 5 package?
Editor note; note all company data sheets indicate that the metal can is in fact a TO-5 package; however, the dimensions, when provided, do indicate a TO-5 metal Can package.
Is the to 5 package the same as the to 205 package?
Also refer to the 8-Lead TO-5 package [same package different lead count]. Some documents make reference to a TO-5 package being similar to or being replaced by a TO-205AA [ TO-205 ]. So some data sheets may indicate that a device is in a TO-5 package or TO-205 package.
How many terminals are in a to 5 case?
Transistor Can Packages TO-5 Case style, Metal Can. 8-Lead TO-5 Metal Can. The TO-5 is a through-hole device enclosed in a metal can, with 8 leads or terminals, additional contacts are possible. In some cases the metal can is isolated from the terminals and used to attach a heat sink.
