FEATURES
DESCRIPTION
• Total power dissipation:
max. 500 mW
Low-power voltage regulator diodes in hermetically sealed leaded glass
SOD27 (DO-35) packages.
• Tolerance series: ±5%
The diodes are available in the normalized E24 ±5% tolerance range.
The series consists of 37 types with nominal working voltages from 2.4 to 75 V
(BZX55-C2V4 to BZX55-C75).
• Working voltage range:
nom. 2.4 to 75 V (E24 range)
• Non-repetitive peak reverse power
dissipation: max. 40 W.
