A diode mainly consists of only 2 terminals(anode,cathode).A SCR mainly contains one more terminal called GATE.The main purpose of the gate in an SCR is just to provide pulses.The main draw back of SCR is it is not fully controllable device.
silicon controlled rectifier is a 3 terminal 4 layer device which has 2 consecutive P N junctions here the three terminals called anode, cathode and gate gate controls the conduction of the scr but diode just conducts in forward bias and blocks in reverse bias
A diode is connected in parallel with a Silicon Controlled Rectifier (SCR) to provide a path for reverse current during the turn-off process. When the SCR is turned off, it may experience a reverse voltage, and the diode allows this reverse current to bypass the SCR, preventing damage from high voltage spikes. This configuration helps protect the SCR from voltage transients and ensures proper operation in circuits where inductive loads are present.
gunn diode is transfered electron device & PIN diode is semiconductor device
the High voltage rated diodes are power diodes while of low rating or normal voltage rating are considered to as ordinary / normal diode
the energy required to break covalent bond in si is 1.1ev and in ge is 0.7ev
scr is basically a three terminal device can be used as diode by leaving one terminal
silicon controlled rectifier is a 3 terminal 4 layer device which has 2 consecutive P N junctions here the three terminals called anode, cathode and gate gate controls the conduction of the scr but diode just conducts in forward bias and blocks in reverse bias

difference between detector and diode
K = 1 [π − α + 1 sin(2α )] is the formula of calculating the SCR firing circuit diagram with diode.
The SCR and TRIAC are essentially controlled diodes.
A DIAC is simply a diode that breaks down at predictable voltage.A TRIAC is a 3 terminal device that will conduct whether the anode is at a positive or a negative potential, controlled by a gate.Another answerThey are AC versions of the SCR and diode respectively. Do you need more details?

The difference in the 1N4007 diode and the 1N4007S diode is the voltage. The 1N4007S has a higher voltage but the meaning of the S is not listed.
An SCS has an additional gate - the anode gate. It is physically smaller than an SCR and has smaller leakage and holding currents than an SCR.
I's a electronic component that act like a controlled diode. It can be used as a switch on some applications, but with some limits. 1- A SCR is a diode, and as such, it only conduct in one direction. 2-The SCR only turn off when the current passing it reaches zero.
Zener diode is heavily doped pn junction diode.
