How to Get Long Term Performance in a Circuit
For long term performance it is suggested to use any component atleast 20% below from its maximum ratings, and same goes with 2SC1971, the maximum collector current of the transistor is 2A therefore do not drive load of more than 1.6A, the max collector to emitter voltage is 17V therefore do not drive load of more than 13.6V. Do not drive output power of more than 5 watts, use a proper heatsink with the transistor and always store or use this transistor in temperature above -55 degree Celsius and below +150 degree Celsius.
