IC's / Transistors / Diodes

These diodes are good for reverse polarity protection (put it between your DC power jack and circuitry to avoid a negative-voltage that would fry your electronics), kickback protection (place across your solenoids, relays & DC motors to safely discha

Grove – MOSFET enables you to control higher voltage project, say 15VDC, with low voltage, say 5V, on microcontroller. MOSFET is also a kind of switch, but its switching frequency can reach up to 5MHz, much faster than normal mechanical relay.

This transistor from ONSEMI can switch up to 40V with a peak current of 1A.

Semiconductor NPN Transistor

An optocoupler is used to control another circuit without them having an electrical connection. The 4N35 is commonly used. This is a pack of 5.

The 1N4148 is a standard silicon switching diode. It's one of the most popular diodes because of its dependable specifications and low cost. Use it for signals up to 200mA of current.
