概要
Description
The BZX84-C18 is a surface-mount Zener diode designed for voltage regulation and protection in low-power circuits. Key features:
- Zener Voltage (Vz): 18V (±5%)
- Power Dissipation: 350mW
- Package: SOT-23 (compact for PCBs)
- Applications: Voltage clamping, signal conditioning, and overvoltage protection in portable electronics.
It operates in reverse breakdown (Zener) mode, maintaining a stable 18V output when biased correctly. Ideal for precision voltage references or protecting sensitive components from voltage spikes.
For reliable performance, ensure current stays within limits (typically <20mA). Check datasheet for exact specifications.
