I have just tested two 36v zeners(1N5258) to see where they clamp.
One thru-hole part (Diodes inc)and one mini-melf (Vishay). I charged
a 10uf cap and discharged into zener through a 10ohm resistor.
The thru-hole part clamped at 40v with 2 amps of current. The melf
part went to 55v with only 400ma.
What's up with these two supposedly identical parts?
regards,
Bob
