Which of the following diodes is a signal diode?

A.

0A79

B.

BY127

C.

1N4007

D.

DR25

Correct option is A



Explanation:
The 0A79 is a type of signal diode, which is designed for small-signal applications, such as rectifying small voltages or detecting signals. Signal diodes are typically used in circuits where the current and voltage are low.
· BY127 is a rectifier diode used in power supply circuits.
· 1N4007 is a general-purpose rectifier diode, commonly used for blocking high voltages in power supply circuits.
