DESCRIPTION
Low-power voltage regulator diodes in hermetically sealed leaded glass
SOD27 (DO-35) packages. The diodes are available in the normalized E24
±
1% (BZX79-A),
±
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.
Fig.1 Simplified outline (SOD27; DO-35) and symbol.
The diodes are type branded.
