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. Fig.1 Simplified outline (SOD27; DO-35) and
symbol. LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 60134).
