Re: Samsung LJ92-01511A SMPS Component
Found an equivalent zener diode manufactured by ROHM. It's a different package, but identical specs.
The part number is: TFZGTR30B

I'm really looking for a substitute, because I can't seem to source the RLZ30BLeave a comment:

Samsung LJ92-01511A SMPS Component
I have attached an image of the back of the power supply. I had a zener diode ZD8001, that was open in both directions.
From my understanding, the zener in question is of type: Rohm LL-34
If this is the case then the part number for the zener would be: RLZ30B
Is this correct? What can I use as a substitute?Attached FilesPremium supporters get full download access and other benefits.

Dear members,
I have a linear variable power supply with unknown brand name that I used for voltage injection.
Then it failed. I discovered that its transistors (Q1 and Q2) are shorted.
In addition, I discovered that its zener diodes are defective.
I can replace the burned transistors.
But I do not know the model of the zener diodes. the model number is not marked on the zener diodes.
Therefore, I cannot replace the zener diodes.
I do not want to test the zener diodes in a test circuit to discover their model or value.
no schematics are available... -
