We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

BOZEMAN, Mont. -- ILX Lightwave Corporation, a leader in laser diode instrumentation and test systems, announced today a major laser diode test service contract with ABB Bomem of Quebec, Canada. Under ...

The polarity markings on LEDs (Light Emitting Diodes) seem to be a common cause of confusion. The polarity may be indicated by a flat section on one side of the body or by one lead being shorter than ...

Some diode manufacturers caution against using the diode tester function in ohmmeters because it could exceed the reverse-voltage and forward-current ratings of sensitive diodes. This is especially ...

Keithley Instruments, Inc. has introduced a dual-channel picoammeter with dual ±30V independent, non-floating bias sources and 1fA measurement resolution. The Model 6482 picoammeter provides two ...

Diodes Incorporated (Diodes) (Nasdaq: DIOD) today announced the successful completion of its acquisition of ElevATE ...

The reliability assessment of light-emitting diodes (LEDs) underpins the widespread adoption of solid-state lighting across domestic, commercial and industrial sectors. Key performance metrics include ...

Zener diodes are PN junction devices that are designed to operate in the reverse-breakdown region. The breakdown voltage (Vz) of Zener diodes is set by carefully controlling the doping level during ...

Diode arrays, such as a SIP diode array, are a single inline or system packaged diode array. The objective of SIP diode arrays is to merge many electronic requirements of a functional system or a ...

In the first part of this series, we took a look at a “toy” negative-differential-resistance circuit made from two ordinary transistors. Although this circuit allows experimentation with ...
