1. General description

General-purpose Zener diodes in a SOD323F (SC-90) very small and flat lead Surface Mounted

Device (SMD) plastic package.

2. Features and benefits

• Total power dissipation: 550 mW

• Tolerance series: B: approximately 5 %; B1, B2, B3: sequential, approximately 2 %

• Small plastic package suitable for surface mounted design

• Wide working voltage range: nominal 2.4 V to 51 V

• Very low leakage current for a given reverse voltage for types PZU5.1B - PZU10B

• PZU5.1B2 - 10B: Very low dynamic impedances at low currents, very low leakage current, hard

breakdown knee

• PZU11B2 - 51B: Intentional minor rise of leakage current for optimized fast switching and noise

reduction [Ref. AN90031]

• AEC-Q101 qualified

3. Applications

• General regulation functions
