Many years ago I was using 2N918 transistors in an RF application. That transistor comes in a size TO-72 package, which has four leads, one each for the collector, the emitter, the base and the ...

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 ...

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 ...

The German PV testing equipment provider said its new Sinus-3000 Pro line is an ‘all-in-one system’ that can perform power measurements, bypass diode testing, insulation testing, visual inspection, ...

FitTech, a provider of LED probing, testing, and sorting equipment, has expanded its footprint in new industries such as compound semiconductor and laser diode testing, where it anticipates ...
