FAQs: Your Questions Answered

Q: What is the difference between a diode and a transistor?

A: Diodes allow current to flow in only one direction, while transistors are semiconductor devices that can control the flow of current or act as an amplifier.

Q: What is the forward voltage drop of a diode?

A: The forward voltage drop is the voltage that appears across a diode when current flows in the forward direction. It is typically a small value, ranging from a few tenths of a volt to a few volts.

Q: What is the reverse leakage current of a diode?

A: The reverse leakage current is the small amount of current that flows through a diode when it is reverse biased. It is typically a very small value, in the nanoampere or microampere range.

Q: What is the maximum operating temperature of a diode?

A: The maximum operating temperature of a diode varies depending on the type of diode and its packaging. Most diodes can operate up to temperatures of 150°C or higher.

Q: What is the typical lifespan of a diode?

A: The typical lifespan of a diode is very long, exceeding 100,000 hours under normal operating conditions.
