Different semiconductor diode designs are tailored for specific roles in electronic systems. Match each specialized diode type on the left with its primary operating function on the right.
- Zener DiodeMaintains a steady reference voltage by safely conducting current in reverse breakdown
- Light-Emitting Diode (LED)Emits visible or infrared light when energized by forward-biased current
- PhotodiodeActs as an optical sensor by increasing reverse current when exposed to light
- Schottky DiodeProvides high switching speeds and a low forward voltage drop for high-frequency circuits
Answer
Zener Diode matches maintaining a steady reference voltage in reverse breakdown; Light-Emitting Diode matches emitting light when forward biased; Photodiode matches acting as an optical sensor in reverse bias; Schottky Diode matches providing high switching speeds and low forward voltage drop.
Each diode type utilizes semiconductor properties for a targeted function: Zener diodes maintain a stable clamping voltage in reverse breakdown, LEDs emit photons when forward-biased, photodiodes sense light through light-induced reverse current, and Schottky diodes allow high-speed rectification with a lower forward voltage drop.
