2N3846T3 Temperature-Power Derating Curve [2N3847T3]
NPN Power Switching Silicon Transistor. Package, TO-257AA.
2N3847-T3 Transistor Operational Power Derating Curve
Use the Curves to determine maximum operational power based on operational case temperature, derate power as required. Attach a Heatsink to the metal tab of the 2N3846, or provide forced air via a Fan to increase power dissipation for a given temperature.
Transistor Derating Curves
Temperature derating is common practice in engineering designs.
