How to check transistor with multimeter pdf
(PDF) A STUDY ON MULTIMETER | RishiRaj Srivastava - heavenlybells.orgOne particularly usefull skill is knowing how to test a transistor using a digital multimeter. Specialized component analyzers exist to do this task. For this test, you can view the transistor as two diodes connected as shown in how to check transistor using digital multimeter pdf; how to test. In order to do this. To test a silicon diode such as a 1N or a 1N all you need is an ohm-meter.

Low resistance readings on the base with the black negative - leads correspond to an N-type material in the base of a PNP transistor. The P-type emitter corresponds to the other end of the arrow of the base-emitter junction, the emitter. The collector is very similar to the emitter and is also a P-type material of the PN junction. Meter readings will be exactly the opposite, of course, for an NPN transistor, with both PN junctions facing the other way. This forward voltage difference is due to the disparity in doping concentration between the emitter and collector regions of the transistor: the emitter is a much more heavily doped piece of semiconductor material than the collector, causing its junction with the base to produce a higher forward voltage drop. Knowing this, it becomes possible to determine which wire is which on an unmarked transistor.
