1. What is the working principle of a single rectifier diode?
A rectifier diode conducts current when forward biased, converting the positive half wave of alternating current into direct current. When reverse biased, the diode blocks the current, thereby preventing the negative half wave from passing through and achieving rectification effect.
-
2. What is forward voltage drop?
Forward voltage drop refers to the voltage drop generated when the current passes through a diode when it is conducting. The forward voltage drop of silicon rectifier diodes is usually around 0.7V, while the forward voltage drop of Schottky diodes is usually lower, between 0.2V and 0.3V.
-
3. What is the maximum reverse voltage (PIV) of a rectifier diode?
The Peak Inverse Voltage (PIV) is the maximum reverse voltage that a diode can withstand. When selecting a diode, the PIV must be higher than the maximum reverse voltage in the circuit, usually twice or more the input voltage.
-
4. How to identify the polarity of a single rectifier diode?
Rectifying diodes usually have polarity markings, with the positive (anode) of the diode being "+" and the negative (cathode) being "-". On the packaging of diodes, there is usually a circular mark on the cathode side indicating the direction of the diode.
