IEC 60747-5-7:2016

Overview

IEC 60747-5-7:2016 is an international standard published by the International Electrotechnical Commission (IEC) that focuses on semiconductor optoelectronic devices, specifically photodiodes (PDs) and phototransistors (PTs). This standard defines critical terminology, essential ratings and characteristics, and outlines precise measuring methods for these devices. It consolidates and replaces previous standards IEC 60747-5-1, IEC 60747-5-2, and IEC 60747-5-3 concerning photodiodes and phototransistors, streamlining the framework for these semiconductor components.

By establishing internationally agreed-upon definitions and performance metrics, IEC 60747-5-7:2016 ensures consistency in design, testing, and application of photodiodes and phototransistors across the electronics and optoelectronics industries.

Key Topics

• Terminology & Definitions
  The standard provides clear definitions of physical concepts related to optical and electromagnetic radiation, including terms such as optical radiation, visible radiation, infrared radiation, ultraviolet radiation, and the photoelectric effect. It defines device-specific terms including optical axis, optical port, photodiode, and phototransistor to standardize descriptions across manufacturers and users.
