About this product
The BZX55C39 is a 39V Zener diode rated at 0.5W in a DO-35 glass package. It conducts in reverse once the voltage reaches its Zener breakdown level, which makes it useful for voltage reference, simple voltage clamping and small regulation circuits. The cathode end is marked by a band on the body.

Frequently asked questions
What is the price of BZX55C39 Zener Diode 39V 0.5W DO-35 in Egypt?
BZX55C39 Zener Diode 39V 0.5W DO-35 currently costs 0.5 EGP in Egypt.
Where can I buy BZX55C39 Zener Diode 39V 0.5W DO-35 in Egypt?
BZX55C39 Zener Diode 39V 0.5W DO-35 is available from Makers Electronics and RAM Electronics. Compare the offers above to find the best price.
Which way round should I install the BZX55C39?
In a shunt regulator the cathode band goes toward the positive rail and the anode toward ground, so the diode is reverse-biased at its Zener voltage. Reversing it makes the diode behave like a normal forward diode with about 0.7 V drop.
What series resistor do I need with the BZX55C39?
Always use a series resistor to limit current. The maximum power is 0.5 W, so at 39 V the current should stay below about 12.8 mA. Calculate the resistor from the supply voltage and the load current you need.
