FEATURES
Silicon Planar Power Zener Diodes
The Zener voltages are graded according to
the international E 24 standard. Standard Zener
voltage tolerance is 5%. Replace suffix "C" with
"B" for 2% tolerance. Other voltage tolerances and
other Zener voltages are available upon request.

(2) Valid provided that leads are kept at ambient temperature at a distance of 8 mm from case
(3) The BZX55C0V8 is a silicon diode with operation in forward direction. Hence, the index of all parameters should be "F" instead of "Z".
