The recommended PCB footprint for the 2SC3679 is a standard TO-220 package with a minimum pad size of 5mm x 5mm and a thermal pad size of 2mm x 2mm.
While the 2SC3679 is a general-purpose NPN transistor, it's not recommended for high-frequency switching applications above 100 kHz due to its relatively high transition frequency (fT) of 150 MHz.
To ensure the 2SC3679 operates within its SOA, follow the maximum ratings and electrical characteristics specified in the datasheet, and consider factors such as voltage, current, power dissipation, and temperature.
The recommended heatsink for the 2SC3679 depends on the application and power dissipation requirements. A heatsink with a thermal resistance of 10°C/W or lower is recommended for high-power applications.
Yes, the 2SC3679 can be used in a linear amplifier circuit, but its relatively low current gain (hFE) of 100-300 may require additional circuitry to achieve the desired gain and stability.
