Frequently asked questions
What is the price of MM1Z30 Zener Diode 30V 500mW SMD SOD-123 in Egypt?
MM1Z30 Zener Diode 30V 500mW SMD SOD-123 currently costs 0.9 EGP in Egypt.
Where can I buy MM1Z30 Zener Diode 30V 500mW SMD SOD-123 in Egypt?
MM1Z30 Zener Diode 30V 500mW SMD SOD-123 is available from Makers Electronics. Compare the offers above to find the best price.
How do I wire the MM1Z30 as a 30V voltage reference?
Connect the cathode to the positive rail and the anode to ground, with a series resistor between the supply and the cathode. Choose the resistor so the current through the diode keeps the dissipation within the 500mW rating.
Can the MM1Z30 clamp a 24V supply rail?
Not reliably. Its minimum Zener voltage is 28V, so it will not regulate or clamp a 24V rail. Pick a Zener whose voltage range starts above your working voltage.
