Emerging as the industry's highest voltage bipolar transistors designed for audio amplifier output stages, the MJL4281A (NPN) and MJL4302A (PNP) 15A, 230W power transistors specify a sustained ...

In 1964, when I started working in the electronics industry, a single silicon transistor cost over £1 ($2.80 at the time, or about $22 at 2014 prices). These cheap ones were not very good and higher ...

The base leg acts as the control and needs around 0.6 volts (V) to switch ‘on’. Once an input of 0.6 volts has triggered the base leg, a much larger current can flow through the collector or emitter ...

Last time on Circuit VR, we looked at creating a very simple common emitter amplifier, but we didn’t talk about how to select the capacitor values, or much about why we wanted them. We are going to ...
