Safe Operating Guidelines:

Here are some guidelines for using the transistor safely:

  • Do not drive the transistor to its absolute maximum ratings and stay at least 20% below from these absolute maximum ratings.
  • So according to the above guidelines, the max collector-emitter voltage (VCEO) of the transistor is 80V but according to the 20% rule mentioned above, we will not go above 64V.
  • The maximum collector current of the transistor is 500mA but we will not drive load of more than 400mA.
  • Moreover, store or operate the transistor within these temperature ranges -65 °C to +200 °C.
