BZX85 Series
V
Z
Range: 3.6 to 200 Volts
Zener Diodes
Power Dissipation: 1.3W
Features
Silicon Planar Power Zener Diodes.
For use in stabilizing and clipping circuits with high power
rating.
The Zener voltages are graded according to the international
E 24 standard. Replace suffix "C" with "B" for
±
2% tolerance.
Other voltage tolerances and other Zener voltages are available
upon request.
