DESCRIPTION
Low-power voltage regulator diodes in hermetically sealed
leaded glass SOD27 (DO-35) packages. The diodes are
available in the normalized E24 ±2% (BZX79-B) and
approx. ±5% (BZX79-C) tolerance range. The series
consists of 37 types with nominal working voltages from
2.4 to 75 V.
The diodes are type branded.
