Frequently asked questions
What is the price of MM1Z3V3 Zener Diode 3.3V 500mW SMD SOD-123 in Egypt?
MM1Z3V3 Zener Diode 3.3V 500mW SMD SOD-123 currently costs 0.9 EGP in Egypt.
Where can I buy MM1Z3V3 Zener Diode 3.3V 500mW SMD SOD-123 in Egypt?
MM1Z3V3 Zener Diode 3.3V 500mW SMD SOD-123 is available from Makers Electronics. Compare the offers above to find the best price.
How do I calculate the series resistor for the MM1Z3V3?
Use R = (Vin - Vz) / (Iz + Iload), where Vz is about 3.3V. Pick Iz comfortably below the level set by 500mW divided by 3.3V, and check that the resistor's power rating covers the voltage drop across it.
Is the MM1Z3V3 accurate enough for an ADC voltage reference?
It can give an approximate 3.3V reference, but its 3.1V to 3.5V range, 95Ω impedance and leakage current make it less stable than a dedicated voltage reference IC. For precise ADC measurements, use a precision reference.
