A little confusing to say it's a short circuit at 130V. Better to say it will start to conduct around 130V and will conduct more and more as the voltage increases but will still have around 130V across the zener. Looking at the datasheet, it will start to conduct around 128V and will reach the rated 1W at about 134V.130V is the voltage at which it will break down (If you don't know, that's what zeners do). So 130V for your application isn't negotiable. When the reverse bias (130V) breaks down, the zener is essentially a short circuit so it will generate heat. The wattage indicates how much heat it can handle. This diode doesn't seem very popular so you might have to look about. You could fit a larger wattage as Pommie suggests but need to check its physical size and type. In other words will it fit.
Well confusing it may be but that is more or less what happens, that's why a current limiting resistor is usually if not always in circuit to stop the zener going pop!A little confusing to say it's a short circuit at 130V. Better to say it will start to conduct around 130V
That is not what happens. According to your explanation, a 16k resistor is a short circuit - check the maths. A short circuit has no resistance and no voltage across it! I answered the question asked by the OP without referring to "the excruciating exactness of a data sheet". I only referred to the datasheet as you don't seem to know how a zener works.Well confusing it may be but that is more or less what happens, that's why a current limiting resistor is usually if not always in circuit to stop the zener going pop!
Also what's the difference between a short circuit and conducting? Pretty much the same me thinks, a short circuit definitely conducts.
I was trying to make it easy for ravi17 (who is obviously new to the joys of zener diodes) to understand. I doubt he will be much interested in the excruciating exactness of a data sheet. Little steps, he wants to know which zener he can use.
I don't see that at all.My we are touchy.
