Small Signal Zener Diodes
FEATURES
• Silicon planar power Zener diodes
• Standard Zener voltage tolerance is ± 5 % with
a “B” suffix in the ordering code (e.g.: 1N5221B),
suffix “C” is ± 2 % tolerance
• These diodes are also available in MiniMELF
case with the type designation TZM5221 to
TZM5267, SOT-23 case with the type
designations MMBZ5225 to MMBZ5267 and
SOD-123 case with the types designations MMSZ5225 to
MMSZ5267
