BZX58550 series

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

Applications
