PIN diode Working, Structure and Application PIN diode What is PIN diode A PIN diode is one type of diode in which a wide undoped (pure form), intrinsic semiconductor region placed between (sandwiched) a P-type and N-type semiconductor region. It is a silicon semicon-ductor diode in which a high resistivity intrinsic I-region is sandwiched between a P-type and N-type region. Pin diodes are used for a number of applications. The low forward resistance of the intrinsic region decreases with increasing current. Due to this large magnitude of an electric field, the electron-hole pair generation will augment up to a large extent and this, in turn, can process even a weak input signal.

The wide intrinsic region is in difference to an ordinary PN diode. This unidirectional behavior is called rectification, and is used to convert alternating current to direct current. Application ID: 74891 This tutorial performs steady-state and transient analysis of the response of a PIN diode to constant and pulsed radiation, respectively. “The use of a tunnel diode connected in parallel with a backward diode in pulsed systems,” Telecommunications and Radio Engineering, Pt.2 21, 1966, p. 109. The PIN diode is a diode with a wide, it lightly doped intrinsic semiconductor region between a p- type semiconductor and an n-type semiconductor region. conventional PIN diode it has a more reverse voltage. A diode is a two-terminal electronic component that conducts current primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance in one direction, and high (ideally infinite) resistance in the other. The PIN diode is one of the popular device options for switches. In this way, a diode can detect the presence of light. At the dawn of the industrial diode laser technology, people were already proud of 1 kW. The resistance vs. current behavior of a typical PIN diode is shown in figure 2. When the diode is operated under ‘0’ bias condition which means that there is no application of external voltage to the diode. A depiction of a PIN diode. The pin diode consists of heavily doped p and n regions separated by an intrinsic (i) region, as shown in Figure (a). Median response time is 34 minutes and may be longer for new subjects. Materials and Methods The PIN Diode The BARC developed PIN diode is similar to a p-n junc-tion diode but it is fabricated on a high resistivity silicon substrate. The wide intrinsic region in the PIN diode makes it suitable for fast switches, attenuators and high voltage power applications. A simplified equivalent circuit of the PIN diode is shown in figure 1. ; This region normally heavily doped as they are used for ohmic contacts. When forward-biased, it acts like a current-controlled variable resistance. Elle est constituée d'une couche de semi-conducteur intrinsèque haute résistivité en sandwich entre les couches de type P et de type N d'une diode classique ; d'où le nom de PIN, qui reflète la structure de la diode (Figure 8). Today, Laserline's diode lasers are offered as standard in power ranges between 500 W and 25 kW, and with special configurations, even up to 60 kW are attained in tests, while 100 kW are possible with the current construction method. This signifies that the potential barrier restricts the current flow. A backward diode is essentially a tunnel diode, whose one side of the junction has relatively less doping concentration compared to the other side.

Whereas when the diode operates in forwarding bias conditions, there will be a thinner potential barrier. Placed across a trans-mission line, the PIN diode becomes an absorption-type attenuator which permits sine-wave, square-wave, and pulse modulation without frequency pulling. The backward diode or the back diode is a P-N junction diode, whose operation is similar to that of tunnel diode and Zener diode.
