Reverse leakage testing Reverse leakage may be measured only after removing the component from the circuit board because shunt resistances abound in almost all circuits. Good silicon rectifiers and ...

Figure 1 This circuit protects low-power laser diodes but is not suitable for higher-power laser diodes. The circuit in Figure 2 avoids these deficiencies. It is similar to the standard JFET circuit ...

In the VIN1 path, a diode drop can throw the supply voltage out of tolerance: 3.3 V 10% has a minimum of 2.97 V, so a typical diode drop (0.6 V) places VIN1 outside the 10% limit.

By combining 49 of them he’s put together a soda bicarb diode steering circuit for a 7-segment display capable of showing the digits 0 to 9.

At 100 mA, for instance, a diode drops about 270 mV but the alternative circuit drops only 10 mV. This circuit switches loads without intervention from a microcontroller or system software.

Tiny light-emitting diodes with optical microsystems that can produce all the colors of the rainbow, a new method for producing printed circuit boards – Fraunhofer researchers are showing ...
