LM393 Comparator IC : PinOut, Specifications, Circuit, Working, Datasheet & Its Applications

By

An electronic circuit that makes a comparison between two voltage levels or input signals is called a comparator. This IC compares the two applied inputs to it & generates an output that specifies which of the inputs is lesser or greater. If the non-inverting input is higher as compared to the inverting input, then output goes high and if the inverting input is higher as compared to the non-inverting, then output goes low. There are different types of comparator ICs like LM311, LM393, LM2903 … [Read more...]

BT139 TRIAC : PinOut, Specifications, Circuit, Working, Datasheet & Its Applications

By

TRIAC or Triode for Alternating Current is a three-terminal AC device that is used mainly for switching AC. Generally, TRIACs are made with two SCRs which are connected in a reverse-parallel arrangement by gates coupled to each other. TRIACs and SCRs are different because, in TRIACs, it allows the flow of current in both directions whereas an SCR allows current in only a single direction. Most TRIACs are activated by providing either a positive (+ve) or negative (-ve) voltage to the gate … [Read more...]

1N4007 Diode : PinOut, Specifications, Circuit, Working, Datasheet, Equivalents & Its Applications

By

A diode is a two-terminal semiconductor device that works as a one-way switch mainly for current within a circuit. The diode allows the flow of current easily within a single direction and restricts the flow of current severely from supplying in the other direction. This can be called a uni-direction device and it can be used as a rectifier within the electronic circuit. Generally, the diode works in a forward-bias condition whereas in a reverse-bias condition, current does not supply throughout … [Read more...]
