Transistor Tester Kit (#1757)
This is the Bipolar Transistor Tester Kit. It will test your Bipolar Transistors. When there is no Transistor to be tested, the LM555 will light up both LEDs. When a good NPN Transistor is put in, the GREEN LED will come on. When a good PNP Transistor is put in, the RED LED will come on. If either has a Collector-to-Emitter short, neither of the LEDs will come on. If the Transistor to be tested has an open, both of the LEDs will continue to light up.
This is also an excellent way to determine if a Transistor is an NPN or a PNP!! In order for the circuit to work properly, you must know which is the Emitter, the Collector and the Base. The E-B-C test pins are also available at the end of the PCB so you can remote them to test other Transistors that do not fit in the pins.
The PCB is double-sided, plated thru-holes, 1.20" long x 2.20" wide made of .062" FR-4 epoxy glass. It has green Solder Mask (LPI) on both sides with white Silk Screen on the Top side. There are also four mounting holes.
This kit does not include the tools you will need to assemble the circuit. You will need tools such as a soldering iron, solder, wire cutters, etc.
We supply the parts, you supply the ingenuity. You will get the following:
