PZU18B2L,315

A Zener Diode is a special type of diode that is designed to operate in the breakdown region. The PZU18B2L,315 diode is a single diode, in which a single p-n junction is formed between two semiconductor materials. The diode is designed with a heavily doped n-type region adjacent to a lightly doped p-type region. This asymmetry in doping creates a potential barrier and, in turn, acts as a voltage-controlled device.

The PZU18B2L,315 diode is a commonly used device due to its various advantages. It has a low reverse leakage current and a low reverse breakdown voltage. Moreover, it has a low on-state voltage drop and a low forward voltage. The diode is also capable of withstanding higher reverse breakdown voltages. As a result, it can be used in applications where the peak inverse voltage (PIV) is higher than normal.

The PZU18B2L,315 diode is primarily used in the application of voltage-regulated power supplies. The device can be used to regulate the output voltage of an AC power supply. It functions by allowing the flow of current in only one direction until the voltage reaches a certain threshold. Once the voltage reaches this threshold, the diode starts to conduct in the reverse direction and restricts the flow of current. As a result, the output voltage is limited to a predetermined setting.

The PZU18B2L,315 also has other applications such as voltage regulation in computer logic circuits, surge protection, and over-voltage protection in radio frequency amplifiers. It is also used in automotive circuits as a voltage regulator. The device is also used in controlling the voltage levels of digital signals in microcontroller-based circuits.

The PZU18B2L,315 diode has a maximum current rating of up to 1.5 amperes and its power dissipation can range from 0.90 watts to 2 watts. Its reverse breakdown voltage is 18 volts, with a maximum temperature coefficient of 6 mV/°C. The diode has a low capacitance of about 0.47 pF, which makes it suitable for high-speed switching applications. Its forward voltage can range from 0.1 volts to 1.0 volts.

The working principle of the PZU18B2L,315 diode is similar to conventional diodes. When a forward voltage is applied to the diode, it starts to conduct and allow current to flow in a single direction. When the voltage exceeds a certain pre-set value, the diode conducts in the reverse direction. This, in turn, restricts the flow of current and limits the voltage level of the output signal.

The PZU18B2L,315 is a versatile device and is used in various applications. It is an effective solution for voltage regulation in various applications and can withstand voltage surges up to 18 volts. This diode also offers a low reverse leakage current, a low on-state voltage drop, and a low forward voltage. It also has a high power dissipation rating and a low capacitance, making it suitable for high-speed switching applications.
