PLZ39B-HG3/H

Application Field and Working Principle of PLZ39B-HG3/H.

Introduction

The PLZ39B-HG3/H type is a single Zener diode, a type of semiconductor device commonly used as a voltage regulator in electronic circuits. It is typically a PN-junction diode configured to have a low breakdown voltage between the anode and cathode terminals. The device is typically only capable of conducting current in the forward direction and is characterized by the voltage at which the junction breakdown occurs. This diode is often used to provide a stable voltage output in applications such as power supplies and circuit protection.

Detailed Description

The PLZ39B-HG3/H is a 200 mW, dual-terminal, hermetically sealed diode device with a standard PN-junction semiconductor construction. A single Zener diode, it is designed for use in precision voltage regulation and power supply applications, with a cathode-anode breakdown voltage of 3.9 Volts. Manufactured using standard PN-junction technology on a ceramic substrate, the device is capable of operating over a wide current range while maintaining a high level of reliability and performance.

The PLZ39B-HG3/H diode consists of an n- region and a p-region, which form the PN-junction. This junction is responsible for the electrical characteristics of the device. As a voltage is applied to the PN-junction, a small amount of current is able to flow until a certain voltage, known as the Zener voltage, is reached. At the Zener voltage, the PN-junction breakdowns and the entire current start flowing through the diode. This breakdown voltage is the rated breakdown voltage of the diode and remains constant until the diode fails or is overstressed.

The PLZ39B-HG3/H diode is designed to have an extremely low leakage current and a high reverse breakdown voltage. This allows the device to operate in a wide variety of applications such as voltage regulation and power supply applications, where precision voltage regulation and low power loss are required. The device is also designed to be temperature compensated and features a temperature coefficient of typically less than 60mV/°C.
