The parameter we are looking for is the maximum collector emitter voltage, Vceo max. So the TIP31 is still a contender. Now we need to calculate whether we can provide sufficient base current to keep the transistor in saturation.
First we need to find what the base current will be when the transistor is carrying the worst-case current of 1. This means that for our collector current of 1.
Next we check the base current. Finally we need to select a base resistor which will be low enough to ensure that the TIP remains saturated, but high enough to prevent the Arduino from trying to deliver more current than it should. Back to Figure 2 where we see that when the collector current is 1 A, Vbe sat is about 1. Now if the Arduino is putting out 5 V, and Vbe is 1.
Example 2 This example is from an excellent discussion here. A TIP is proposed. Can the TIP handle the load current? Can the transistor handle the 12V required? According to the same table as above, Vceo max is 60V, well more than we need. Instead, look at Figure 2 on page 3. Compare to the maximum current an output of the Raspberry Pi can deliver.
There is some confusion over this, but as discussed on this page 1. Find Vbe. According to the graph in Figure 2, Vbe sat is below 1. Now we calculate the voltage drop across the base resistor.
The output voltage of the Raspberry Pi is 3. Recall that the minimum base current we need to drive the transistor into saturation is 1. How does our transistor switch perform with the motor is operating at the other extreme, the no-load current of only 76 mA?
How do we verify that the transistor is still saturated, i. Electronic Component Catalog.
