Safe Operating Guidelines / Absolute Maximum Ratings:

Read and follow these safe operating guidelines for better long term performance.

  • Do not use the transistor to its absolute maximum ratings, using a component to its absolute max ratings may provide stress on the component which result in damaging the component, make it weak or make its life short. For better and long term performance of a component use it atleast 20% below from its max ratings.
  • The max collector current is 25A so do not drive load of more than 20A.
  • The maximum collector to emitter voltage is 100V therefore drive load under 80V.
  • Use a suitable heatsink with the transistor.
  • And always store or operate it at temperatures above -65°C and below +150 °C.
