Description
The BZX84C15 is a 15V Zener diode in a SOT-23 surface-mount package, designed for voltage regulation and protection in low-power circuits. Key features:
- Zener Voltage (Vz): 15V (typical) with tight tolerance options.
- Power Dissipation: 350mW (at 25°C).
- Current Range: Operates optimally at 5mA (test current).
- Applications: Voltage clamping, reference voltage generation, and overvoltage protection in portable electronics, sensors, and PCB designs.
Its small size and low leakage current make it ideal for space-constrained applications. Ensure proper current limiting (via a series resistor) to avoid exceeding power limits.
For exact specs, refer to the datasheet (e.g., from Diodes Inc. or Nexperia).
