About this product
BZX55C27 is a 27V zener diode rated at 500mW, packaged in a glass DO-35 body with 5% tolerance. It holds a near-fixed voltage in reverse breakdown, which makes it suitable for simple voltage regulation, clamping and reference circuits in student and hobby projects. The black band marks the cathode end.

Frequently asked questions
What is the price of Zener Diode BZX55C27 27V 0.5W DO-35 in Egypt?
Zener Diode BZX55C27 27V 0.5W DO-35 currently costs 0.5 EGP in Egypt.
Where can I buy Zener Diode BZX55C27 27V 0.5W DO-35 in Egypt?
Zener Diode BZX55C27 27V 0.5W DO-35 is available from Makers Electronics. Compare the offers above to find the best price.
How do I wire the BZX55C27 as a voltage regulator?
Connect the cathode (black band) to the positive rail and the anode to ground, in parallel with the load. Place a series resistor between the supply and the cathode to limit current through the diode.
Can it handle any input voltage above 27V?
No. The series resistor must be sized for the input voltage and the load current, and the total dissipation must stay within the 500mW rating of the diode.
