WebMay 7, 2024 · May 7, 2024. #11. The definitive answer is "maybe". Germanium turns on at a much lower voltage than silicon, so they're not meant to be directly swappable. … WebMay 31, 2024 · The circuit is set up to accept a germanium transistor. The idea is, instead of replacing the blown one with another terribly expensive obsolete part that will probably fail, modify the circuit to accept a comparable silicon transistor which would provide more reliability at a significantly lower price.
WebSep 13, 2007 · A silicon transistor is generally a "better" transistor, but it is the "bad" part of the germanium transistor that is being used. It saturates more, the gain depends on the currents more. And it is slower. The transistors are driven into saturation. The silicon transistor goes up to the power supply, then clips and give sharp edges. this WebThe first junction transistors were sandwiches of N- and P-type germanium (germanium with an excess and scarcity of electrons, respectively). A weak voltage coming into the …
WebFeb 27, 2024 · V BE is the voltage that falls between the base and emitter of a bipolar junction transistor. V BE is approximately 0.7V for a silicon transistor. For a germanium transistor (which is more rare), V BE is approximately 0.3V. V BE is important when doing DC analysis of a transistor circuit because it is used for calculations to find the ...
