To measure a zener diode’s breakdown voltage, you need a dc voltage source whose voltage exceeds that of the zener voltage. In Figure 1, resistor R SER provides voltage drop between V IN and V ZEN. In ...

Testing for failure with a multimeter is only partially effective, whereas a dedicated optocoupler testing circuit provides clear results in just seconds. For related tutorials and step-by-step build ...

This document gives focus on optocouplers including its basic principles, operation, and common applications. Suggested techniques in order to maximize the device’s efficiency are included. Cases ...

The AL8866Q, an automotive-compliant LED driver from Diodes Inc., is designed to drive an external MOSFET. The DC-switching LED driver-controller supports buck, boost, buck-boost, and SEPIC topologies ...

This file type includes high resolution graphics and schematics. LEDs are the most efficient way to turn an electric current into illumination. When a current flows through a diode in the forward ...

Diodes has launched the AL8843Q and AL8862Q automotive-compliant DC-DC buck LED drivers, designed for single and multiple LED strings in and around vehicles. Applications include daytime running ...
