A 3.3-volt Zener diode is a semiconductor device used to regulate and stabilize voltage in electronic circuits. When reverse biased, it maintains a nearly constant voltage of approximately 3.3 V by operating in the Zener breakdown region, providing reliable reference voltage and protection against over-voltage conditions.
This diode is commonly available in an axial-lead through-hole package and is suitable for low-power regulation circuits, microcontroller interfaces, and signal conditioning applications.
