With 250 mW power dissipation and a Zener voltage range of 9.8V to 10.2V at 5 mA test current, this diode is designed for precision voltage reference and regulation in analog circuits. The SOT-23 footprint is widely supported by automated assembly equipment and offers a compact solution for surface-mount designs. The B suffix ensures tighter voltage regulation compared to the +\/-5% C suffix, making this device ideal for applications where voltage accuracy directly impacts circuit performance.","working_principle":"The BZX84-B10 operates in the reverse breakdown region when biased above its 10V Zener voltage. In this avalanche breakdown mode, the diode maintains a relatively constant voltage across its terminals over a range of reverse currents. The +\/-2% tolerance ensures the actual breakdown voltage falls between 9.8V and 10.2V at the 5 mA test current, providing a stable reference. The Zener impedance (differential resistance) at the operating point determines the voltage regulation quality; lower impedance yields better regulation against load current variations. At 10V, the breakdown mechanism is dominated by avalanche effect rather than the Zener tunneling effect, resulting in a positive temperature coefficient typical of higher-voltage Zener diodes.","pin_description":"\n
