BZX399 datasheet



This is Voltage regulator diode. Low-power low noise voltage regulator diodes in SOD323 plastic SMD package. The diodes are available in the normalized E24±5% tolerance range. The series consists of 34 types with nominal working voltages from 1.8 to 43 V.


1. Total power dissipation: max. 300 mW

2. Tolerance: ±5%

3. Working voltage range: nom. 1.8 to 43 V (E24 range)

4. Improved IZ/VZ characteristic at low currents
(IZ = 50 mA). This results in a noise free and sharp breakdown knee.


1. General regulation functions, where low noise at low currents is required

2. Low power consumption applications (e.g. hand-held applications).
