Frequently asked questions
What is the price of MM1Z4V7B SMD Zener Diode 4.7V 500mW SOD-123 in Egypt?
MM1Z4V7B SMD Zener Diode 4.7V 500mW SOD-123 currently costs 0.9 EGP in Egypt.
Where can I buy MM1Z4V7B SMD Zener Diode 4.7V 500mW SOD-123 in Egypt?
MM1Z4V7B SMD Zener Diode 4.7V 500mW SOD-123 is available from Makers Electronics. Compare the offers above to find the best price.
Can it replace a 5V regulator to power a load?
No. It is a shunt voltage reference and clamp, not a regulator, and it cannot supply significant load current. Use a dedicated linear or switching regulator to power loads.
Which resistor do I need with it?
Use a series resistor to set the current through the diode. Calculate its value from the supply voltage and the current you need through the Zener, keeping the power within the 500mW rating.
