The SCR has only two states of operation i.e. it can be either fully ON or completely OFF hence SCR can as a switch. There is no “active” region of operation like a transistor.

Here are the basic electronics tutorial circuits for beginners. You can find here tutorials on operational amplifiers (opamp), transistor, MOSFETs, 555 timer IC, audio amplifiers and many more.
VI Characteristics of SCR (Silicon controlled rectifier)
The VI characteristics of SCR (silicon-controlled rectifier) is a graph of anode current Ia on the y-axis and anode to cathode voltage on the x-axis as shown in the graph. The characteristics in the reverse direction (anode to cathode voltage negative) is similar to a reverse-biased diode. SCR is a member of the thyristor family. […]
What is Silicon Controlled Rectifier SCR
Silicon Controlled Rectifier (SCR) is one of the oldest four-layer solid-state power device it was invented in 1957. SCR has the highest power handling capacity in comparison with other semiconductor devices. It has three terminals namely anode, cathode, and gate
Opamp as Differentiator (active differentiator)
A differentiator opamp is an opamp configuration that produces a differentiated version of the signal applied to its input terminal. This process is exactly the opposite of integration. by interchanging the positions of components in an integrator circuit we can get a differentiator circuit. Here we’re going to discuss two types of differentiator circuit: Ideal […]
OP AMP integrator Circuit
The circuit in which output voltage waveform is an integration of the input signal is called as an integrator or op-amp integrator or integrating amplifier. The output voltage is proportional to the amplitude and duration of the input signal. Ideal op amp Integrator Circuit: The above circuit is obtained by replacing the feedback resistor RF […]
Voltage Follower OPAMP or buffer Amplifier
OPAMP buffer or voltage follower is an opamp configuration whose gain is equal unity. Voltage follower is also known as unity gain amplifier, voltage buffer, opamp buffer, or an isolation amplifier. It is used to separate two circuits having the same voltage level but different impedance. In a voltage follower circuit output voltage and input […]
