Frequently asked questions
What is the price of Zener Diode 1N4731A 4.3V 1W DO-41 in Egypt?
Zener Diode 1N4731A 4.3V 1W DO-41 currently costs 1 EGP in Egypt.
Where can I buy Zener Diode 1N4731A 4.3V 1W DO-41 in Egypt?
Zener Diode 1N4731A 4.3V 1W DO-41 is available from Makers Electronics. Compare the offers above to find the best price.
How do I wire the 1N4731A as a 4.3 V reference?
Connect a series resistor from a higher supply to the cathode, and the anode to ground. The cathode is marked by the black band. The voltage across the diode stays near 4.3 V. Size the resistor so the Zener current stays within the 1 W rating and above the minimum needed for regulation.
Can I connect it directly to a 5 V logic supply?
Not directly. A 4.3 V Zener on a 5 V rail will draw large current because it is close to breakdown, so always use a series resistor. Without it the diode can be damaged.
