The circuit has been constructed to test and measure the voltage rating of zener diodes. To be able to test the voltage rating of a zener diode up to 50 VDC, a small transformer and a single 555 timer ...

Diodes whose reverse-breakdown characteristics are controlled precisely during manufacture are called as Zener diodes and are intended specifically for operation in the reverse breakdown mode ...

Work has started on a new €4.3 million project to improve the brilliance of laser diode bars and develop a direct-diode technology suitable for metal welding and cutting. The European Commission is ...

Glasgow, UK-based Vector Photonics is leading the Bloodline research and development project; an Innovate UK-funded, international consortium project developing PCSEL-based chips (Photonic Crystal ...
