I want to create a circuit having delay of 2 ms. Is this the right way to draw this?

 

Hi moon,
What load is the output connected too?

E

Output is connected to an scr whose ig is 15mA max and Vgt is 1.3v Vgd is 150 mv

SCR is TN5015H-6T

 

hi m,
Using the datasheet and your figures of 1.3Vg at 15mA, indicates an input load of ~90R.

In LTSpice using that load indicates the SCR will not trigger.

Update: In your simulation, try a 470R and a 10uF
