BZX84-V-Series
Vishay Semiconductors
Small Signal Zener Diodes
Features
• These diodes are also available in other
case styles and other configurations
including: the SOD-123 case with type
e3
designation BZT52 series, the dual zener
diode common anode configuration in the SOT-23
case with type designation AZ23 series and the
dual zener diode common cathode configuration
in the SOT-23 case with type designation DZ23
series.
• The Zener voltages are graded according to the
international E 24 standard. Standard Zener volt-
age tolerance is ± 5 %. Replace "C" with "B" for
± 2 % tolerance.
• Silicon Planar Power Zener Diodes
• Lead (Pb)-free component
• Component in accordance to RoHS 2002/95/EC
and WEEE 2002/96/EC
