Frequently asked questions
What is the price of MM1Z27 Zener Diode SMD 27V 500mW SOD-123 in Egypt?
MM1Z27 Zener Diode SMD 27V 500mW SOD-123 currently costs 0.9 EGP in Egypt.
Where can I buy MM1Z27 Zener Diode SMD 27V 500mW SOD-123 in Egypt?
MM1Z27 Zener Diode SMD 27V 500mW SOD-123 is available from Makers Electronics. Compare the offers above to find the best price.
What is the maximum Zener current for the MM1Z27?
At 500 mW and about 27 V, the maximum Zener current is roughly 18.5 mA. Use a series resistor to keep the operating current within this limit.
Can I use it to clamp a 24 V supply?
Not as a clamp for a 24 V rail. Its Zener voltage starts at 25.1 V, so it would not conduct at 24 V. Choose a Zener voltage slightly above your normal operating voltage.
