How To Use S9013 Transistor
The S9013 is a high current fast NPN transistor that can be used for general-purpose switching and amplification. It has a transition frequency of 140MHz. The transition frequency of a transistor is the frequency at which current gain drops to one, beyond which the transistor can no longer amplify signals. This limited bandwidth is due to internal parasitic capacitances.
The S9013 also has a high collector current rating of 500mA. However, at high currents, the gain drops off rapidly and a base current of up to 50mA is needed to achieve high collector currents. The power dissipation must also be taken into account. While the package is capable of dissipating 625mW, the thermal resistance of the TO-92 case limits the practical power dissipation. The thermal resistance is specified in degrees Celsius per watt. It specifies the rise in temperature for given power dissipation, and the junction temperature must never rise above 150˚C.
