Three Pin Diode

The p type and n type regions are typically heavily doped because they are used for ohmic contacts.

Three pin diode.

A pin diode is a diode with a wide undoped intrinsic semiconductor region between a p type semiconductor and an n type semiconductor region. Integrated circuits are put into protective packages to allow easy handling and assembly onto printed circuit boards and to protect the devices from damage. The diode in which the intrinsic layer of high resistivity is sandwiched between the p and n region of semiconductor material such type of diode is known as the pin diode. The wide intrinsic region is in contrast to an ordinary p n diode the wide intrinsic region makes the pin diode an inferior rectifier one typical.

The pin diode comprises a semiconductor diode having three layers naming p type layer intrinsic layer and n type layer as shown in the figure below. Mouser offers inventory pricing datasheets for sot 23 3 pin diodes. A standard sized 8 pin dual in line package dip containing a 555 ic.

I don t have a solid answer as to why they do this but will share a few possibilities for debate. This is a fairly common practice in the industry. After the pn junction diode was developed in the year 1940s the diode was first exercised as a high power rectifier low frequency during the year 1952. The p and n regions are there and the region between them consists of the intrinsic material and the doping level is said to be very low in this region.

A very large number of different types of package exist. The high resistive layer of the intrinsic region provides the large electric field between the p and n region. Used in voltage protection circuits. In general single diodes in 3 lead sm packages have no connection on the third pin.
