Safe Long Run in a Circuit:
To get a very good performance with this Darlington transistor we suggest always stopping below its max ratings. It can not work in circuits using more than 100V. Do not put load over and always use a suitable base resistor to supply the required current on its base. Use a suitable heatsink to save it from overheating and to store its temperature below -65 centigrade and more than +150 centigrade.
