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 designation BZT52
series, the dual zener diode common anode con-
figuration in the SOT-23 case with type designa-
tion AZ23
series and the dual zener diode common cathode
configuration in the SOT-23 case with type desig-
nation 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.
