About SMD Zener Diode Finder

The SMD Zener Diode app is an essential, offline pocket toolkit designed for electronics engineers, repair technicians, and hardware hobbyists. Whether you are identifying an unknown component on a circuit board or designing a new schematic, this app provides instant, accurate data right at your fingertips.

Key Features: • Built-in Series Resistor Calculator: Never burn out a Zener diode! Instantly calculate the exact series resistor (Rs) and power wattage needed to protect your component based on your source voltage and load current. • Premium Modern Interface: Enjoy a beautiful, intuitive "glassmorphism" UI with visually distinct component cards. • Dark & Light Modes: Fully integrated theme support for comfortable viewing in bright labs or late-night workbench sessions. • Quick Search Categories: One-tap quick filters help you instantly browse by Part Code, Package, Brand, or Voltage. • 100% Offline Access: No internet connection is required to search the database or use the calculator, making it perfect for on-the-go troubleshooting.

Core Search Capabilities: • Intelligent Search Logic: The app automatically detects your input format. Search seamlessly by part code (e.g., BZX84C5V1), exact voltage (supports 5.1V, 5V1, or 5.1 formats), manufacturer, or package type (SOD-123, SOD-323, DO-41). • Comprehensive Local Database: Access an extensive, built-in library of Zener specifications. • 100% Offline Access: No internet connection is required to search the database or use the calculator, making it perfect for on-the-go troubleshooting.
