    Hi. I'm a newbie to electronics.

    I have a interesting in zener diode that i think i can use it for
    low voltage cut off of my rechargeable lithium battery(3.6V working

    I thought zener works like a resistor of high impedence under 0.7V in
    direction. So, I connect two zener diodes parrel connect with
    different direction and one of its ends to my battery's (+) ve pin.

    But, it doesn't work the way I thought. What happen?

    The zener diode that i used is 1.0W-5.1V

    Thanks for your kind reply.

    Hi Joonhwan,

    Sorry, but not in this way.

    The lower zener drops the voltage to (1) 0V7, while the other does
    nothing at all (assuming you do not charge the battery through it).

    When anti-paralleling zeners, they works just like if you used ordinary
