Frequently asked questions
What is the price of MM1Z18 SMD Zener Diode 18V 500mW SOD-123 in Egypt?
MM1Z18 SMD Zener Diode 18V 500mW SOD-123 currently costs 0.9 EGP in Egypt.
Where can I buy MM1Z18 SMD Zener Diode 18V 500mW SOD-123 in Egypt?
MM1Z18 SMD Zener Diode 18V 500mW SOD-123 is available from Makers Electronics. Compare the offers above to find the best price.
Do I need a series resistor with the MM1Z18?
Yes. In reverse bias the diode needs a series resistor to limit current and keep power within the 500mW rating.
Can it be used with a 12V supply?
Not as a regulator for 12V. Its nominal voltage is 18V, so it will not hold a 12V rail. Select a Zener whose nominal voltage matches your target.
