WebJan 20, 2024 · Yes it is but you need to know what voltage the switch has on it. As it is a radio it is very unlikely to be 5V. The point about using a PNP transistor as a top switch like this, is that the signal you put on the base of the transistor needs to be as big as the voltage you are switching. WebJul 26, 2024 · When saturated, the switch is said to be on. Providing sufficient base drive current is a key problem in the use of bipolar transistors as switches. The transistor provides current gain, allowing a relatively large current in the collector to be switched by a much smaller current into the base terminal.

WebDec 30, 2024 · Transistor 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. WebA transistor can be used to enable an IC connected to a low voltage supply (such as 5V) to switch the current for a load with a separate DC supply (such as 12V). The two power supplies must be linked. Usually their 0V connections are linked and an NPN transistor is used on the IC output.
