Voltage regulator diodes
FEATURES • Total power dissipation: max. 300 mW • Tolerance: ±5% • Working voltage range: nom. 1.8 to 43 V (E24 range) • Improved IZ/VZ characteristic at low currents (IZ = 50 µA). This results in a noise free and sharp breakdown knee. APPLICATIONS • General regulation functions, where low noise at low currents is required • Low power consumption applications (e.g. hand-held applications). DESCRIPTION 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. MARKING
