About this product
The BZX55C30 is a 30V, 500mW Zener diode in the industry-standard DO-35 glass package. It holds a near-constant voltage across its terminals in reverse breakdown, which makes it suitable for voltage reference and regulation in low-power circuits. Its reverse leakage current is only 100 nA at 22 V, so it draws little current below breakdown.

Frequently asked questions
What is the price of BZX55C30 Zener Diode 30V 0.5W DO-35 in Egypt?
BZX55C30 Zener Diode 30V 0.5W DO-35 currently costs 0.5 EGP in Egypt.
Where can I buy BZX55C30 Zener Diode 30V 0.5W DO-35 in Egypt?
BZX55C30 Zener Diode 30V 0.5W DO-35 is available from Makers Electronics. Compare the offers above to find the best price.
How do I use the BZX55C30 as a voltage reference?
Reverse-bias it: connect the cathode band to the positive supply through a series resistor, and the anode to ground. The voltage across the diode will hold near 30 V once the supply exceeds the Zener voltage and the current is within range.
What is the maximum current for the BZX55C30?
With a 500 mW rating at 30 V, the maximum current is about 16.7 mA. Keep the operating current below this value by choosing the series resistor carefully, especially when the supply voltage is high.
