DO-123 Two-Terminal Surface Mount Package

This time a 2-Terminal package was added to the Engineering Site. Under the main page covering Diode Packages, a link to the new page relating to the SOD-123 package style is inculded.

TO-276 Three-Terminal Surface Mount Package

What is a TO-276 device?
A 3-Terminal Surface Mount Component, shown on; TO-276 Transistor Package.
As discussed on that page the package may be used for any number of different semiconductors, but the term transistor is used in general. As with all the other related packages the TO-276 page is linked off the Transistor Packages page.

There's not much left to say, as this posts relates to the last two previous posts, which have already covered every thing.

This is the first surface mount package added to that section of the web site, all the other pages cover some type of through hole package. However I have had pending data on several other surface mount styles but the data has not been added yet because I been working other site issues ~ I'm not sure if I can add yet another package type in the next few days or not. Of course the Site-Map was also up-dated.

Plastic Transistor Body

Following yesterdays posting regarding the addition of the TO-63 transistor package I added yet another transistor package. This newest addition adds a Plastic TO-226 Transistor, very closely related to a Plastic TO-92.

The TO-226 is a common molded plastic case transistor; however because it's a plastic body it's not really used in any government specifications, so there are no BJT Dearting Curves provided as a link. In many cases I add these component bodies and indicate they are transistor devices, but any three terminal part could reside within these component shapes; including FETs and Transistors, or an SCR, Triac, or 3-terminal references or Temperature Sensors.... Of course some of these package will handle more power than others and may not accommodate higher current or voltage applications. Here is the top level page linking all Transistor Packages.

Both the new page on the TO-226 device and the TO-63 device added yesterday have been included in the Engineering SiteMap.

As normal with many new pages, this one is a copy of a preexisting page on the Engineering Site. However over time I'll add more data as I get back to that topic. The page on the TO-63 started out with a bit more data. I should be adding another related page on Friday.

TO-63 Transistor Package

I just added a page showing the TO-63 Package Style. I'm not really sure how it was missing, because the drawing was being used on a few pages. As normal it's a copy of another page [TO-61 Case], but with a different graphic. Next time I get to it I'll add some data to the page.

The main page that shows a number of different links for; Transistor Cases.

Many of the pages that also use or point to the pages describing transistor packages is the How to Derate Transistors.

In general I indicate that this is a transistor package, but any three terminal device could reside in the package.

The graphic is a B-52 Control Panel, lower deck. 
Much of the gear does not look like it fits, like it's a mix of different up-grades over the years.
