Frequently asked questions
What is the price of 1N4730A Zener Diode 1W 3.9V DO-41 in Egypt?
1N4730A Zener Diode 1W 3.9V DO-41 currently costs 1.71 EGP in Egypt.
Where can I buy 1N4730A Zener Diode 1W 3.9V DO-41 in Egypt?
1N4730A Zener Diode 1W 3.9V DO-41 is available from UGE. Compare the offers above to find the best price.
How do I wire it to get a stable 3.9V?
Connect the cathode (the banded end) to the positive supply and the anode to ground, with a series resistor to limit current. Zener regulation requires reverse bias, so the cathode must be on the positive side.
What current can it handle?
At 3.9V, a 1W rating corresponds to a maximum of roughly 256 mA (1 W ÷ 3.9 V). Keep the actual power dissipation below the rating, and allow more margin at high ambient temperatures.
