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-Q - PZU10B-Q
• PZU5.1B2-Q - 10B-Q: Very low dynamic impedances at low currents, very low leakage current,
hard breakdown knee
• PZU11B2-Q - 51B-Q: Intentional minor rise of leakage current for optimized fast switching and
noise reduction [Ref. AN90031]
• Qualified according to AEC-Q101 and recommended for use in automotive applications

3. Applications
• General regulation functions
