Diodes are devices that allow current to flow in only one direction. Zener diodes are devices made up of a PN junction with a wide and heavily doped P-region and a thinner and lightly doped N-region connected in reverse-biased. A PZU3.9B1A,115 is a type of Zener diode which is used in many applications.A PZU3.9B1A,115 Zener diode is a 3.9 Volt, 1.5 Watt diode. The PZU3.9B1A,115 structure consists of an N-type substrate, an N + emitter region, a P + base region, and a P – collector region, with a Zener breakdown voltage at 3.9 volts. The maximum reverse voltage of the PZU3.9B1A,115 is 5 volts, while its operating temperature range is between -65°C to +175°C.The working principle of the PZU3.9B1A,115 diode can be understood by first understanding the structure of the diode. A Zener diode has two junctions, a P-N junction and a Zener junction, with an added Zener region that is heavily doped. When the diode is forward-biased, a large current flows through the diode from the P-region to the N-region. When reverse-biased, the Zener voltage across the junction increases, and the current flowing through the diode decreases. This is known as the Zener region breakdown and is the working principle of the PZU3.9B1A,115 diode.The PZU3.9B1A,115 diode is used in a variety of applications. These diodes are often used as voltage references, voltage regulators or protection devices.
