WebTransistor switches can be used to switch and control lamps, relays or even motors. When using the bipolar transistor as a switch they must be either “fully-OFF” or “fully-ON”. Transistors that are fully “ON” are said to be in their Saturation region. Transistors that are fully “OFF” are said to be in their Cut-off region. Web12 de mai. de 2024 · The ratio of collector/base current is often called β, or hFE. It can be in the hundreds for small signal transistors, and is typically in the many tens for power transistors. It's fairly constant over many orders of magnitude of current variation, which is why it's worth giving a name to it.
