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.
