Single Zener Diodes FAQ

What is the marking code for the BZX84C27WHE3?

The marking code for the BZX84C27WHE3 is KPA.

How is the Zener impedance derived?

Zener impedance is derived from the 60-cycle AC voltage resulting when an AC current with an RMS value equal to 10% of the DC Zener current is superimposed on the DC current.
