Differentiate, distinguish, compare and explain what is the main difference between power diode and signal diode. Comparison and Differences.
Difference between Power diode and Signal diode
1. Power diode is constructed with n-layer, called drift region between p+ layer and n+ layer. In Signal diode, drift region is not present.
2. The voltage, current and power ratings are higher in the power diode while it is lower in signal.
3. Power diodes operate at high speeds. Signal diode operates at higher switching speed.
