It provides a nominal Zener voltage of 5.1 V with \u00b12% tolerance, making it suitable for precision voltage regulation and reference applications. The BZX84 series includes 37 breakdown voltages from 2.4 V to 75 V in three tolerance series: \u00b11% (BZX84-A), \u00b12% (BZX84-B), and approximately \u00b15% (BZX84-C). The device features total power dissipation up to 250 mW and non-repetitive peak reverse power dissipation of 40 W. It is AEC-Q101 qualified, ensuring reliability in automotive environments. The operating temperature range extends from -65\u00b0C to +150\u00b0C.","working_principle":"The BZX84-B5V1 operates in the reverse breakdown region of its P-N junction. When the reverse voltage across the diode reaches the Zener voltage (5.1 V nominal), the diode begins conducting current while maintaining a relatively stable voltage across its terminals. This voltage regulation property is based on Zener breakdown (for voltages below approximately 5.6V) where quantum tunneling of charge carriers occurs in the heavily doped junction. The \u00b12% tolerance ensures the actual breakdown voltage remains between 5.0 V and 5.2 V. The diode must be operated with an appropriate series current-limiting resistor to ensure the Zener current stays within the recommended range (IZ = 5 mA nominal) while keeping power dissipation below 250 mW.","pin_description":"\n
