This article describes the Mosfet Tester (C9014). The content is very simple, very helpful. Components in this article can help you understand better understanding of this article. For example, in this article, you can go to find and buy these components:C9014.

This circuit included in the category astable multivibrator. This circuit is used to test? N-Mosfets (the power kind e.g irf830), whether it works or not. If it is not working, the LED will not flash. If Mosfet is working it will operate in the astable multivibrator circuit causing the Led to flash. Here? is the circuit diagram:

mosfet tester circuit schematic

To make the circuit cheap, the other half of the astable utilizes an npn transistor. This circuit can test almost any NPN transistor.? As a common emitter buffer that also drives the led as it receives pulses from the Mosfet drain, this circuit uses the NPN transistor

Note:
Diode that used in this circuit is a light emitting diode.
