1. What is a single rectifier diode?
A single rectifier diode is an electronic component used to convert alternating current (AC) to direct current (DC), typically used in power supplies, chargers, and other circuits that require DC power.
-
2. 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.
-
3. What is a fast recovery diode?
Fast recovery diode is a special type of rectifier diode with a short reverse recovery time, suitable for high-frequency power supplies and switch mode power supplies (SMPS) applications, reducing switching losses.
-
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.
