The BD250 Transistors (NPN/PNP) TO-3PN manufactured by SPTECH are RoHS compliant, high-performance, switching transistors designed for use in audio, low-frequency high-power amplification purposes. It is composed of three NPN silicon epitaxial transistors and three PNP silicon epitaxial transistors housed in a plastic TO-3PN package. The BD250 transistor provides improved high-power current gain band width, fast switching speed, and low collector-base capacitance. Its features include a maximum collector current of 75A, collector-emitter voltage of 200 volts, and a maximum power dissipation of 2.2 W. The package is hermetically sealed, and it has two mounting holes for a secure attachment. The device is designed to handle large signal currents with high frequency and transient power applications. It is ideal for power amplification and switching in audio applications, as well as low-frequency power amplification in high-powered transistors.
