I'm designing a Crowbar over voltage protection circuit with following specifications,
Maximum input voltage - 30V
Maximum input current - 5A
Output voltage - 5V
Output current - 5A
So I have chosen zener diode (1n4733A -> Vz = 5.1V,Iz = 49mA) and (2n5060 -> Vgt = 0.8) components for my circuit.
According to the calculation I choose R = 16.3265ohms resistor. But my simulation doesn't work as I expected.
(For more information I have attached screenshots of my Multisim simulation)
Could you please help me to solve my problem?
