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 ...

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 ...

Performing single-point pass/fail DC tests on packaged diodes is critical to ensure compliance with manufacturers’ specifications and weed out defective devices before they are shipped. Most types of ...

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, ...
