PENENTU B-C-E TRANSISTOR SCHEMATIC DIAGRAM

SKEMA RANGKAIAN PENENTU B-C-E TRANSISTOR

Basis-Collector-Emitter Transistor

Testing procedure:

    * Connect randomly the pins of the transistor under test to J1, J2 and J3 sockets or clips.
    * Close SW1, SW2 and SW3.
    * Push on P1; if the transistor is in good health the response of the Identifier will be:
    * Two terminals will show both LEDs illuminated, the remaining one will show a single LED illuminated.
    * If the LED illuminated is Red, the pin connected to the related connector will be the Base of a NPN transistor.
    * If the LED illuminated is Green, the pin connected to the related connector will be the Base of a PNP transistor.
    * Open the switch related to the single illuminated LED: the two terminals showing both LEDs illuminated will change their state and a single LED per terminal will be illuminated. The LED which previously indicated the Base pin will turn-off.
    * If the transistor was previously identified as NPN, the pin connected to the now illuminated Green LED will be the Emitter, whereas the pin connected to the Red LED will be the Collector.
    * If the transistor was previously identified as PNP, the pin connected to the now illuminated Red LED will be the Emitter, whereas the pin connected to the Green LED will be the Collector.
