Frequently asked questions
What is the price of Changjing MMSZ5237B 8.2V Zener Diode 350mW SOD-123 SMD in Egypt?
Changjing MMSZ5237B 8.2V Zener Diode 350mW SOD-123 SMD currently costs 1.2 EGP in Egypt.
Where can I buy Changjing MMSZ5237B 8.2V Zener Diode 350mW SOD-123 SMD in Egypt?
Changjing MMSZ5237B 8.2V Zener Diode 350mW SOD-123 SMD is available from Makers Electronics. Compare the offers above to find the best price.
How do I connect it as a simple voltage reference?
Connect a series resistor from the supply to the output node, then connect the Zener cathode to the output node and the anode to ground. The cathode must be on the positive side because the diode works in reverse breakdown. Size the series resistor so the Zener current stays between its minimum and the maximum of about 40 mA (350mW / 8.2V).
Can it protect a 12V line against overvoltage?
It can clamp a line to about 8.2V when used with a series resistor that limits the current, but it is intended for low-current clamping. For higher-power surges, choose a Zener or TVS rated for that energy.
