Its important to note that the manufacturer does not create separate p type and n type material and then glue them together. The depletion region n type and p type material are of little use by themselves.

Then we can say that an ideal small signal diode conducts current in one direction forward conducting and blocks current in the other direction reverse blocking.

How do signal diodes work. They usually have a medium high forward voltage drop and a low maximum current rating. Small signal diodes many electronic systems use small signals these can be categorised as ac continuously varying signals or pulses whose amplitude is limited to a few volts or in many cases a few milli or even micro volts. A single diode in a half wave rectifier circuit clipping out the negative end of an ac signal.

Standard signal diodes are among the most basic average no frills members of the diode family. Signal diodes are used in a wide variety of applications such as a switch in rectifiers current limiters voltage snubbers or in wave shaping circuits. When a diode is forward biased so that electrons and holes are zipping back and forth across the junction theyre constantly combining and wiping one another out.

If you send an ac signal into a circuit then your sole diode will clip out the negative part of the signal leaving only the positive input as a direct current wave. Leds are simply diodes that are designed to give off light. They usually have a medium high forward voltage drop and a low maximum current rating.

Together they form a p n junction.
