Please refer to this link to know more about Depletion Mode MOSFET Enhancement Mode Whereas when the voltage across the gate terminal is either positive or negative, then the channel conductivity decreases. When there is no voltage across the gate terminal, the channel shows its maximum conductance. The MOS capacity that exists in the device is the crucial section where the entire operation is across this. It is insulated from the channel near an extremely thin layer of metal oxide. It specifies the rise in temperature for given power dissipation, and the junction temperature must never rise above 150 ˚ C.The width of the channel is controlled by the voltage on an electrode which is called the gate and it is located in between the source and the drain. The thermal resistance is specified in degrees Celsius per watt. While the package is capable of dissipating 625mW, the thermal resistance of the TO-92 case limits the practical power dissipation. The power dissipation must also be taken into account.
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 S9013 also has a high collector current rating of 500mA. This limited bandwidth is due to internal parasitic capacitances. 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. The S9013 is a high current fast NPN transistor that can be used for general-purpose switching and amplification.
Note: Complete technical details can be found in the S9013 datasheet linked at the end of this page. TO-92 package with 650mW power dissipation.It also has a relatively large collector current capacity of 500mA.Ĭurrent into this terminal controls current between the collector and emitter It features a high transition frequency of 140MHz, making it suitable for high-frequency applications. The S9013 is a medium-power NPN transistor used for general purpose switching and amplification.
