BZX58550 Low-Current Voltage Regulator Diodes

Nexperia BZX58550 Low-Current Voltage Regulator Diodes feature ±5% series tolerance, ≤300mW total power dissipation, and are available in SOD523 (SC-79) SMD plastic package. These diodes operate at 1.8V to 75V operating voltage range, 0.9V forward voltage (V_F), 200mA forward current (I_F), and 40W non-repetitive peak reverse power dissipation (P_ZSM). The BZX58550 diodes are used in low-current general regulation functions.
