WebThe operation of the BJT is based on the principles of the pn junction. As indicated in Figure 6.1, there are two basic types: (a) the npn and (b) the pnp. In the npn, electrons are injected from the forward-biased emitter into the thin base region where, as minority carriers, they diffuse toward the reverse-biased collector. Some of these WebRelays have the advantage for very high currents. Learn how to control a DC motor with a transistor, using PWM. $$ f_{max} = \frac{1}{t_d + t_r + t_f + t_s} $$. In contrast, when the switch is set as closed, the base current will flow through the transistor and change its operation to the saturation region.
