Small Signal Zener Diodes
Features
• These diodes are also available in other
case styles and other configurations
including: the SOD-123 case with type
designation BZT52 series, the zener
diode common anode configuration in the
SOT-23 case with type designation AZ23
series and the 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
voltage tolerance is ± 5 %. Replace "C" with "B" for
2 % tolerance.
• Silicon planar power zener diodes
• AEC-Q101 qualified
• Compliant to RoHS directive 2002/95/EC and in
accordance to WEEE 2002/96/EC
