TIP41C Safe Operating Guidelines

It is recommended not to push the TIP41C transistor to its absolute limits. It's best to stay at least 20% below its maximum ratings. For example, while it can handle a maximum load of 6A, it's safer to avoid exceeding 4.8A. Similarly, its maximum load voltage is 100V, so it's advisable to stay below 80V. Additionally, ensure the transistor's temperature stays between -65°C and 150°C for proper operation.
