The red LED provides visual indication of the current flowing through the resistor-zener-diode circuit. The higher the current ... its voltage drop is equal to that of an ordinary silicon diode, or ...

MOSFET Q1 is turned off and the load gets no current. The circuits illustrated in Figures 1 and 2 may be used to protect a load against reversed battery instead of an ordinary diode reversed-polarity ...

In the first part of this series, we took a look at a “toy” negative-differential-resistance circuit made from two ordinary transistors ... case for actual tunnel diodes, which exploit ...

Plastic Diode Could Lead To Flexible, Low Power Computer Circuits, Memory Date: November 15, 2005 Source: Ohio State University Summary: Researchers have invented a new organic polymer tunnel ...

Ordinary silicon diodes used in switch-mode power supplies ... This allows the use of smaller circuit components without having to sacrifice usable power. In high-power applications, heatsinks ...
