The TIP147 PNP DARLINGTON TRANSISTOR is designed for general purpose amplifier and low frequency switching applications. The TIP140, TIP141, TIP142, (NPN); TIP145, TIP146, TIP147, (PNP) are complementary devices.
PNP transistors are used to source current, i.e. current flows out of the collector. PNP transistors are used as switches. These are used in the amplifying circuits. PNP transistors are used when we need to turnoff something by push a button.
How does it work
The PNP transistor turns on when a small current flows through the base. … The direction of current in PNP transistor is from the emitter to collector. The letter of the PNP transistor indicates the voltage requires by the emitter, collector and the base of the transistor.

An internal link is any link from one page on your website to another page on your website. Both your users and search engines use links to find content on your website. Your users use links to navigate through your site and to find the content they want to find. Search engines also use links to navigate your site. They won’t find a page if there are no links to it.
There are several types of internal links. In addition to links on your homepage, menu, post feed, etc, you can also add links within your content. We call those contextual links. Contextual links point your users to interesting and related content. Moreover, they allow search engines to find out what content on your site is related and to determine the value of that content. The more links an important page receives, the more important it will seem to search engines. Therefore, good internal links are crucial to your SEO.
