Where can I buy MM1Z5V1 Zener Diode 5.1V 500mW ±5% SMD SOD-123 in Egypt?
MM1Z5V1 Zener Diode 5.1V 500mW ±5% SMD SOD-123 is available from Makers Electronics. Compare the offers above to find the best price.
Can the MM1Z5V1 clamp a 5V logic line?
Its 4.8V minimum means it would start conducting close to 5V, so it is not a suitable clamp for a 5V rail. Use it as a reference or limiter set above the normal operating voltage, and check your logic family's input limits.
How do I calculate the series resistor when dropping 12V to 5.1V?
Use R = (Vin - Vz) / (Iz + Iload), with Vin = 12V and Vz close to 5.1V. Choose a resistor value that keeps the Zener current within the limit set by the 500mW rating, and check the resistor's own power rating.
