Safe Operating Guidelines / Absolute Maximum Ratings:

For safe operting of the transistor follow the below guidelines:

  • Do not use the transistor to its absolute max raings and always stay 20% below.
  • The max collector current is 700mA therefore do not drive load more than 560mA.
  • Max collector to emitter voltage of the transistor is 40V so the driven load should not exceed from 32V.
  • Always use a proper heatsink with the transistor.
  • Storage and operating temperature of the transistor should be between -65°C and +200 °C.
