How it works

3 stages · Explore one step at a time

Step 1 / 3

Establish base current

Raise base above emitter through the resistor.

Step 2 / 3

Control the load path

Conventional current flows from collector to emitter.

Step 3 / 3

Release the base charge

The base-emitter return defines off; switching speed depends on drive and stored charge.
