Additional Details

The BZX84C22CA has a Zener voltage (VZ) of 22V with a tolerance of ±5%. It has a low dynamic impedance, which ensures a stable voltage output even with varying current levels. The fast response time allows the diode to quickly clamp voltage transients, protecting sensitive components. The small SOT-23 package allows for high-density mounting on printed circuit boards.

The diode is designed to absorb energy from transient events, preventing damage to downstream circuitry. The Zener voltage is the voltage at which the diode begins to conduct in the reverse direction. It is important to select a Zener diode with a voltage rating appropriate for the application to ensure proper voltage regulation and protection.
