Schottky diodes are used for their low turn-on voltage, fast recovery time and low-loss energy at higher frequencies. These characteristics make Schottky diodes capable of rectifying a current by facilitating a quick transition from conducting to blocking state.
What are the advantages of Schottky diodes?
Advantages of Schottky diode :
- High efficiency.
- Fast recovery time so it can be mostly used in the application of high-speed switching.
- Low junction capacitance.
- The low forward voltage drop.
- It can operate high frequency.
- Schottky diode produces less unwanted noise than P-N junction diode.
- High current density.
Why use a Schottky diode and not just a simple rectifier diode?
When compared to regular p-n junction based diode bridges, Schottky diodes can offer advantages. A forward-biased Schottky diode does not have any minority carrier charge storage. This allows them to switch more quickly than regular diodes, resulting in lower transition time from the sample to the hold step.
