Frequently asked questions
What is the price of Zener Diode 1N4748A 22V 1W DO-41 in Egypt?
Zener Diode 1N4748A 22V 1W DO-41 currently costs 1 EGP in Egypt.
Where can I buy Zener Diode 1N4748A 22V 1W DO-41 in Egypt?
Zener Diode 1N4748A 22V 1W DO-41 is available from Makers Electronics. Compare the offers above to find the best price.
How do I wire the 1N4748A for voltage regulation?
Connect a series resistor from the supply to the cathode, and the anode to ground. The cathode is marked by the black band. The output is held near 22 V once the Zener is in reverse breakdown. Choose the series resistor so the Zener current stays within the 1 W rating.
What is the difference between this and the 0.5 W 22 V Zener?
Both have a nominal Zener voltage of 22 V, but the 1N4748A is rated at 1 W in the DO-41 package, while the BZX55C22 is rated at 500 mW in the smaller DO-35 package. Choose the 1 W type when the Zener must dissipate more power.
