Features
• Silicon Planar Power Zener Diodes
.010 (0.25)
min.
• The Zener voltages are graded according to the
international E 24 standard. Standard Zener volt-
age tolerance is ±5%. Replace suffix “C” with “B”
for ±2% tolerance. Other tolerances and other
Zener voltages are available upon request.
• These diodes are also available in other case
styles and other configurations including: the
SOT-23 case with type designation BZX84 series,
the dual zener diode common anode configuration
in the SOT-23 case with type
