subtitle

Low-current voltage regulator diodes in an SOD523 (SC-79) ultra small and flat lead Surface-Mounted Device (SMD) plastic package.

Features and benefits

  • Total power dissipation: ≤ 300 mW

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

  • Working voltage range: nominal 1.8 V to 51 V

  • Specified at a low test current (50 μA), ideal for low bias and portable battery-powered applications

  • BZX58550-B11-Q to -C51-Q: Intentional minor rise of leakage current for optimized fast switching and noise reduction [AN90031]

  • Qualified according to AEC-Q101 and recommended for use in automotive applications

Applications

  • Low-current general regulation functions
