1. Diodes Key benefits One way current control: diodes allow current to flow in a single direction and block reverse current, enabling reliable rectification and protection in electronic circuits Circuit protection: helps guard sensitive components from reverse polarity and voltage spikes in power and signal paths Flexible options: available in a range of materials and package sizes to suit different design needs Easy integration: compact components that integrate with standard boards and assemblies Important attributes Function: enables forward conduction while blocking reverse voltage Compatibility: suitable for power supplies, protection circuits, and signal paths in common electronic designs Size: offered in multiple package sizes and footprints; exact size varies by model Material: silicon, germanium, and silicon carbide options, depending on model and application Performance: forward current rating, reverse voltage rating, and switching characteristics vary by model; refer to the datasheet for exact values Use scenarios Power supply rectification: used to convert AC to DC in adapters and DC power supplies Reverse polarity protection: placed at input to prevent damage when connectors or batteries are connected incorrectly Signal and protection circuits: employed in clipping, limiting, and protection paths in audio, RF, and digital circuits
