The LED Indication - Discrete category encompasses a range of light-emitting diode (LED) products which are designed specifically for use in indicating discrete status. One of the products in this broad category is the PG1112H-TR. This application provides a brief overview of the device and its associated working principle, as well as potential applications and supporting technical details.

Introduction

The PG1112H-TR is a high-efficiency LED indicating solution specifically developed for customers in need of a powerful discrete indicating solution. It is a reliable, robust and cost-effective device for use in industrial applications for indicating a range of different parameters. This LED indicator can be used effectively for identifying different conditions, such as power status or communications status. It is a 3-lead discrete side-view device that operates over a range of 4.5V to 13.2V.

Working Principle

The PG1112H-TR is essentially a three-layer semiconductor device. A light-emitting diode substrate is placed between two electrically conductive layers. This substrate is based on an active semiconductor material, such as gallium arsenide, combined with an appropriate dopant material. When an electrical current is applied to the two conductive layers, it creates a forward-biased electric field across the device’s substrate. This generates free electrons and holes in the active material, which recombine to emit light. The color of the emitted light depends on the properties of the material used.

Applications

The PG1112H-TR is a versatile device that can be used in a wide range of industrial applications. Some potential applications include status indication for power supply monitoring and communications systems, fault identification, machine condition monitoring, and device protection relaying.

The indicator’s duty cycle can be set to match the application’s requirements. It features a transparent housing for easy viewing of the emitted light. Its robust design ensures durability and reliability over a long period of time. Furthermore, the device has a wide operating temperature range, from -40℃ to +90℃.
