†Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only , and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may af fect device reliability.
NOTES: 1. This value applies when the base-emitter diode is open-circulated.
2. Derate linearly to 100 °C free-air temperature at the rate of 2.67 mW/°C.
3. Derate linearly to 100 °C free-air temperature at the rate of 3.33 mW/°C.
