1. General description
General-purpose Zener diodes in a SOD323 (SC-76) very small Surface-Mounted Device (SMD)
plastic package.

2. Features and benefits
• Non-repetitive peak reverse power dissipation: PZSM ≤ 40 W
• Total power dissipation: Ptot ≤ 320 mW
• Tolerance series:
• B: approximately ±5 %
• B1, B2, B3: approximately ±2 %
• Wide working voltage range: nominal 2.4 V to 51 V (E24 range)
• Low reverse current IR range
• Small plastic package suitable for surface-mounted design
• PZU5.1BA - 10BA: Very low dynamic impedances at low currents, very low leakage current,
hard breakdown knee
• PZU11B2A-51BA: Intentional minor rise of leakage current for optimized fast switching and
noise reduction [Ref. AN90031]

3. Applications
• General regulation functions
