Hello guys!
I am wondering about a simulation in LTSPICE with the Zener diode: BZT52C3V0T-7
I have downloaded the Spice model from the manufacturer website: https://www.diodes.com/part/view/BZT52C3V0T
And I have run a simulation of two cases:
1) Case 1 with R1=150Ohm
2) Case 2 with R1=0Ohm
The case 1 looks ok for me because VZ=3.29V and the Zener is working fine. But the case 2 it does not make sense because Vz=5V and according to the manufacturer, it should be limited to Vz(3V therotically). This issue is also happening when you replace V1 by a OpAmp like this:`
Anyone could explain what is happening?
Thanks in advance!
