Safe Operating Guidelines:

Here are some important safe operating guidelines to get good performance.

  • Do not use the transistor to its absolute and maximum and always stay 20% below.
  • So the maximum collector current is -2A but we will not use more than 1.6A.
  • The maximum voltage to drive the load is 50V minimum.
  • Therefore the maximum collector-emitter voltage is 60V but we should not drive load of more than 50V.
  • The maximum collector current is 2A so we should not drive load of more than 1.6A.
  • The maximum temperature should be between -55°C to 150°C.
