Can we use zener diode as a rectifire"bridge circuit"

[dougy83]

Sorry, dunno. With no load I would expect the output to be close to the value you calculated. Maybe you've got a bad 1N5248B; you could try a different zener sim model.

Isn't a zener diode those little green tic tacs with two wires that I used to desolder out of old Western Electric Model 500 hand sets to use on my audio monstrosities to cut static?

Thanks dougy, but i still have those 13.5V, and can't see where are the other 3 or 3.3V

hi,
If you use LTspice, run this sim of the circuit.

Not specifically. One of those 'green tic tacs' may contain back-to-back zeners or parallel diodes (conducting in opposite directions) to reduce transients. Or it could just be a capacitor or a RC snubber.

Thanks,I tried with an 1N5253B (25V) and its clipped at 24.3V as espected. Really don't know what happened with the other diode. By the way it's Multisim what i'm using.

Anyway, I understood what colin55 was talking about and his point, and it is very useful. But as Brownout said, I think Airian wanted a conventional rectifier.

Thanks anyway.
