@tfix.tech: 🔧 In mobile-phone repair * Rectifier diode: commonly used for power protection and current rectification. * Zener diode: commonly used to clamp/protect a voltage line from excessive voltage. * Schottky diode: very common in high-speed power circuits because its low forward voltage reduces power loss. Important: You cannot always substitute one for another just because they look similar. Check the circuit’s voltage, current, reverse-voltage and switching requirements first. Easy memory trick: Rectifier = convert/block Zener = regulate/protect Schottky = fast + low voltage drop
