Product specification
Voltage regulator diodes
BZX79 series
FEATURES
Total power dissipation: max. 500 mW
Two tolerance series:
±
2%, and approx.
±
5%
Working voltage range: nom. 2.4 to 75 V (E24 range)
Non-repetitive peak reverse power dissipation:

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.
