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.
