How to Safely Long Run in a Circuit:

To safely run this transistor in your circuit for long term do not operate it directly in circuit which are using more than 45V. Also use a suitable resistor base resistor to limit its base current to required level. The maximum temperature in which this transistor can survive is from -55 to +150 centigrade so do not expose it in the temperature below -55 centigrade and above +150 centigrade.
