Visão Geral
Description
- Voltage Range: 18V nominal Zener voltage (Vz) at 5mA.
- Power Dissipation: 200mW (SOD-323 package).
- Applications: Voltage clamping, surge protection, and signal conditioning in consumer electronics, automotive, and industrial systems.
- Advantages: Small form factor, low leakage current, and precise voltage regulation.
It operates in reverse bias, maintaining a stable voltage across its terminals when the breakdown voltage (18V) is exceeded. Suitable for ESD protection and stabilizing voltage in sensitive circuits.
For detailed specs, refer to the datasheet for tolerances, temperature coefficients, and current-voltage characteristics.
Features
- Voltage Range: 18V nominal Zener voltage (Vz).
- Power Dissipation: 500mW (max).
- Package: SOD-323 (small surface-mount).
- Tolerance: ±5% (typical).
- Low Leakage Current: <100nA at VR = 15V.
- Applications: Voltage regulation, overvoltage protection, and signal clamping.
