TIP120 Frequently Asked Questions (FAQs)
-
The maximum current that can be handled by each Darlington pair is 5A, but it's recommended to derate the current to 3A for reliable operation.
-
The base resistor value can be calculated using the formula: Rb = (Vcc - 1.4) / (0.005 * Ib), where Vcc is the supply voltage, and Ib is the desired base current.
-
No, the TIP120 is not suitable for high-frequency switching applications due to its relatively slow switching times (turn-on time: 3us, turn-off time: 5us). It's better suited for low-frequency switching applications.
-
You can protect the TIP120 from back-EMF by adding a flyback diode (e.g., 1N4007) in parallel with the inductive load, and also consider adding a snubber circuit to reduce voltage spikes.
-
The maximum voltage that can be applied to the collector of the TIP120 is 60V, but it's recommended to derate the voltage to 50V for reliable operation.
