G3TR sul sito Americano della Texas Instruments

Il mio progetto G3TR  ( Riconoscitore automatico del Tipo di un Transistor ) è stato pubblicato sul sito della Texas Instruments  ( colosso mondiale dei componenti elettronici e non solo.. ) nella sezione progetti del sistema MSP430 LaunchPad:  TI E2E Community.

G3TR for MSP430 launchpad

G3TR means: Giuseppe Talarico Transistor Type Recognizer.

The test result for the smd transistor in figure (coming from an old graphic board), on a serial terminal with 9600,8,N,1, shows:

G3TR> NPN BJT

The required additional hardware is very simple: just two 10K resistors. A serial terminal (PC or LCD) is needed to show the test result. It allows to identify the type of a transistor. The transistors that can be tested are: pnp or npn bjt; n-channel or p-channel mosfet;low,medium  or high power. It also allows you to test any type of diode locating the external terminal connected to anode. G3TR allows to identify devices (transistor or diode) shorted or broken. The idea that allowed me to make the G3TR is shown in the following figure:

The following is the G3TR graphic processing by students Gabriel Gabriele and Samuele Rotundo.
