How to Safely Long Run in a Circuit:

Here are some safe operating guidelines for using the transistor.

  • First of all, do not use the transistor to its absolute maximum ratings and stay at least 20% below.
  • So the maximum collector current of the transistor is -1A and according to the 20% rule, the derived load should be under 0.8A.
  • Max collector to emitter voltage is -65V so the derived load should be under -52V.
  • Max power dissipation should be under 7W.
  • Always use a heatsink with the transistor.
