1. General description

General-purpose Zener diodes in a small SOT23 Surface-Mounted Device (SMD) plastic package.

2. Features and benefits

• Two tolerance series: ± 2 % and approximately ± 5 %

• Wide working voltage range: nominal 2.4 V to 51 V (E24 range)

• PZU84-B5V1 to -C10: Very low dynamic impedances at low currents, very low leakage current,

hard breakdown knee

• PZU84-B11 to -C51: Intentional minor rise of leakage current for optimized fast switching and

noise reduction [Ref. AN90031]

3. Applications

• General regulation functions
