Multicomp Pro NPN Bipolar Transistor, TO-220, 6A, 100V

The Multicomp Pro BD243C is a robust, high-power NPN bipolar junction transistor (BJT) designed for general-purpose amplification and switching applications. Encased in a durable TO-220 package, this component offers reliable performance in demanding circuits, making it a versatile choice for hobbyists, technicians, and engineers.

It delivers a continuous collector current of 6A and can handle a maximum collector-emitter voltage of 100V, with a substantial power dissipation rating of 65W. Its low junction-to-case thermal resistance of 1.92°C/W ensures efficient heat transfer from the silicon die to the case, which is crucial for maintaining stable operation and longevity in high-power scenarios.

This through-hole mounted transistor features a DC current gain (hFE) minimum of 15 and a transition frequency of 3MHz, suitable for a range of audio and signal processing applications. Its robust construction allows it to operate at temperatures up to 150°C. The three-pin design facilitates straightforward integration into prototypes and finished products on printed circuit boards.
