DESCRIPTION
Low-power voltage regulator diodes in hermetically sealed leaded glass
SOD27 (DO-35) packages.
The diodes are available in the normalized E24 ±5% tolerance range.
The series consists of 37 types with nominal working voltages from 2.4 to 75 V
(BZX55-C2V4 to BZX55-C75).
Fig.1 Simplified outline (SOD27; DO-35) and symbol.
The diodes are type branded.
