The size of the bip is less at lower capacitance (higer Ft), thus less noise. It can be a perfect transistor if you are looking to replace a TIP31, TIP31C or other similar transistors in your circuit design to drive more load. Anyway, this turns out to be one of the more significant contributions to noise in a bipolar transistor. TIP41C is a low cost general purpose power transistor that can be used for amplification and switching purposes in your electronic circuits.

I don't know whether this is truly a case of "capacitance" or not, but it is certainly capacitor-like. Ordinary recifier diodes exhibit this behavior as well when they shut off. Like any other transistor 2N3055 has three pins namely EMITTER, BASE and COLLECTOR. The device is designed for general purpose switching and amplifier applications. Keep in mind the the base-collector side of a transistor is kind of like a diode. 2N3055 is a general purpose NPN power transistor manufactured with the epitaxial base process, mounted in a hermetically sealed metal case.

So why is lower base-output capacitance good? In a class B amp each transistor in a pair shuts off for half a cycle (an over-simplification but ok for this explanation). Safe operating area curves indicate IC VCE limits of the transistor that must be observed for reliable operation i.e., the transistor must not be subjected to greater dissipation than the curves indicate.
Although anything in the Mhz range would seem unrelated to the audio spectrum, higher Ft seems to relate to lower base-output capacitance for similar power/voltage/current parts. a transistor: average junction temperature and second breakdown. "Can you tell me why they look better than the TIPs? Assume that I can use multiple TIPs to make up for lower power ratings."īasically it is the Ft spec.
