This here is a 10 pack of the classic 1N4001 power blocking diode. These are good for reverse polarity protection (put it between your DC power jack and circuitry to avoid a negative-voltage that would zap your delicate electronics), kickback protection (place across your solenoids, relays & DC ..
This package includes 8 different kinds of diodes for common use and is convenient for you to make some small designs.
Diodes were the first semiconductor electronic devices. A diode is a two-terminal electronic component with an asymmetric transfer characteristic, with low resistance to cu..
