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 ...

This video explains how LEDs (Light Emitting Diodes) function and why they are widely used in modern lighting and electronic ...

Electronics are a hot topic today, and kids are eager to master the fundamentals of this interesting and important branch of technology. Here is a basic electronics course for kids that will teach and ...

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 ...

1. Bob Pease used an LM334 current source to servo the current from a PNP transistor through an LED diode. The LM334 will draw current into its V+ pin until the voltage on the R pin reaches 0.068 V.

The function of an LED is to emit light when the device is forward biased within its operating range, and it’s known by most people that an LED can also operate as a photodiode. Perhaps some ...

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 ...
