In this post I have explained how to build a few simple monostable circuits using only transistors, and also learn how to make practical application circuits with them. If you search for transistor monostable circuit online, you will find that one typical circuit has been discussed in all the online articles. This circuit looks a […]

Transistor Multivibrator Circuits [Astable, Bistable, Monostable]
A transistor or BJT multivibrator is a two-stage switching circuit that is configured in a cross-coupled manner. This allows each of the active BJT stages to be regeneratively cross-coupled with the other BJT stage, so that one switches ON when the other switches OFF, and vice versa. This cross-coupling may be set up to switch either a […]
50 Amp Transistor MJ11032, MJ11033 Datasheet, Pinout
If you are looking for high current transistors in the range of 50 amps with a complementary pair, then you can try these Darlington transistors MJ11032 and MJ11033. The MJ11032 transistor is a Darlington NPN power transistor while the MJ11033 is its complementary PNP transistor which is also a Darlington power BJT. Main features The […]
Match Transistor Pairs Quickly using this Circuit
In many critical circuit applications, like power amplifiers, inverters, etc it becomes necessary to use matched transistor pairs having identical hFE gain. Not doing this possibly creates unpredictable output results, such as one transistor getting hotter than the other, or asymmetrical output conditions. By: David Corbill To eliminate this, matching transistor pairs with their Vbe […]
How to Make a Solar Cell from a Transistor
The majority of newbie electronic hobbyists would certainly have a couple of burned up power transistors such as 2N3055 hiding inside their junk box. Supposing we have their internal semiconductor junctions still intact, the device could be transformed into a nice little solar cell by filing or sawing off the top cap of the device, […]
10 Simple Unijunction Transistor (UJT) Circuit Diagrams Explained
In the earlier post I have explained comprehensively about how a unijunction transistor works, in this post I will elucidate a few interesting application circuits using this amazing device called UJT. The example application circuits using UJT which are explained in the article are: 1) Square Wave Pulse Generator The first design below demonstrates a […]
