Frequently asked questions
What is the price of Zener Diode BZX79-C15 15 V 500 mW (DO-35) in Egypt?
Zener Diode BZX79-C15 15 V 500 mW (DO-35) currently costs between 0.5 and 1 EGP across 2 offers in Egypt.
Where can I buy Zener Diode BZX79-C15 15 V 500 mW (DO-35) in Egypt?
Zener Diode BZX79-C15 15 V 500 mW (DO-35) is available from Most Electronics and Future Electronics. Compare the offers above to find the best price.
Can I use the BZX79-C15 for overvoltage protection on a 12 V supply?
It will not conduct on a 12 V rail because its breakdown is at 15 V, so it only clamps above that level. For 12 V protection you would need a lower-voltage Zener, around 12 V to 13 V.
How do I size the series resistor for a 15 V Zener?
Use R = (Vin − 15 V) / Iz, where Iz is the Zener current you want. The input must be above 15 V for the diode to regulate, and the resistor must handle the power dissipated in it.
