Reverse saturation current in zener diode

AI Thread Summary
The reverse saturation current in a zener diode varies significantly based on the specific diode and its characteristics, typically ranging from 0.1 µA to 100 µA. This current is influenced by the zener voltage and the measurement conditions. Data sheets provide detailed specifications for different zener diodes, such as the 1N5221 and 1N5281, which illustrate the varying leakage currents at different voltage levels. For example, the 1N5221 has a leakage of less than 100 µA at 1V, while the 1N5281 shows less than 0.1 µA at 150V. Understanding these specifications is crucial for applications involving zener diodes.

What is the order of the reverse saturation current before breakdown in a zener diode ?
 
Engineering news on Phys.org
What do you mean by "order of the reverse saturation current"?
 
Depends on the diode. It can be in the order of 0.1ua or 100ua depending on the zener voltage and where you measure the leakage.

It is generally specified in the data sheet. Download a data sheet for the 1n5221 - 1n5281 family.
1n5221 is 2.4V zener at 20ma with <100uA leakage at 1V
1n5281 is 200V zener at 0.65ma with <0.1uA leakage at 150V.

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
