DESCRIPTION
ka
MAM239
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
to 75 V.
2.4
The diodes are type branded.
