Frequently asked questions
What is the price of SOT23 SMD Zener Diode BZX84C3V9 3.9V in Egypt?
SOT23 SMD Zener Diode BZX84C3V9 3.9V currently costs 3.42 EGP in Egypt.
Where can I buy SOT23 SMD Zener Diode BZX84C3V9 3.9V in Egypt?
SOT23 SMD Zener Diode BZX84C3V9 3.9V is available from UGE. Compare the offers above to find the best price.
How do I wire the BZX84C3V9 as a voltage reference?
Connect the cathode to the positive rail through a series resistor and the anode to ground. Choose the resistor so the Zener current stays within the datasheet range and the diode dissipates less than 350 mW.
Is the pinout the same for all SOT-23 Zener parts?
Not always. SOT-23 Zener packages can be single or dual-diode with different pin assignments, so confirm the pinout in the manufacturer datasheet before soldering.
