2N4903 +BOM

TO-3 Power Transistor

2N4903 Allgemeine Beschreibung

The 2N4903 is a PNP silicon transistor commonly used in electronic circuits for amplification and switching purposes. It features high current and voltage ratings, making it suitable for various applications.The transistor has a maximum collector current of 0.5A and a maximum collector-emitter voltage of 40V, allowing it to handle moderate power levels. It has a low collector-emitter saturation voltage of 0.6V at 100mA, reducing power dissipation and improving efficiency.The 2N4903 is housed in a TO-92 package, which is a widely used package type for small-signal transistors. This package provides good thermal characteristics and ease of mounting on a circuit board.The transistor has a gain bandwidth product of 100MHz and a transition frequency of 50MHz, making it suitable for high-frequency amplification applications. It has a low input capacitance of 7pF and a low output capacitance of 7pF, ensuring minimal signal distortion at high frequencies.
