PLZ18B-HG3/H

The PLZ18B-HG3/H is one of the single Zener diodes. A Zener diode is a semiconductor diode which allows current to flow in reverse direction when a certain reverse breakdown voltage is exceeded. The Zener diode is typically used in order to maintain a stable voltage across a circuit. The PLZ18B-HG3/H is also known as a “breakdown diode” since its behavior is intended to prevent unwanted current flow in the reverse direction.

When current flows through the device, it creates a voltage drop. This voltage drop is referred to as the forward voltage drop. Similarly, when the reverse voltage is applied to the Zener diode, it creates a voltage drop referred to as the Zener voltage. In general, Zener diodes have a reverse breakdown voltage that is greater than the forward voltage drop. This means that the device will maintain a stable voltage for a wide range of currents.

The PLZ18B-HG3/H has a maximum forward voltage drop of 1.5V and a maximum reverse breakdown voltage of 18V. It is able to supply a maximum power dissipation of 500mW and can operate over a wide temperature range from -55 to+125°C. The diode is also somewhat resistant to temperature drift which helps maintain the stability of the output voltage of the diode.

The Zener diode application field of PLZ18B-HG3/H ranges widely. It is widely used in a CMOS inverter circuit, current mirror, voltage regulator circuit, high speed switch circuit, power supply voltage regulator circuit, etc. The diode is suitable for use in the fields of automotive, telecoms, instrumentation, computer and other applications.

In addition to a stable voltage output, the PLZ18B-HG3/H also offers low power consumption and a low forward voltage drop. It is also highly reliable and able to operate over a wide temperature range. The device also offers a high reverse temperature coefficient which helps maintain a greater temperature stability.

In summary, the PLZ18B-HG3/H is one of the single Zener diodes and is mainly designed to maintain a stable voltage across a circuit. Its maximum forward voltage drop is 1.5V and its maximum reverse breakdown voltage is 18V. The device is widely used in low power applications such as CMOS inverters, current mirrors, voltage regulators, and power supplies. The device can operate over a wide temperature range and is highly reliable and temperature stable.
