BZT52-Series
Vishay Semiconductors
Small Signal Zener Diodes
Features
• Silicon Planar Power Zener Diodes
• 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 designation 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.
