WebAgain, this is easy. Fourth, you need to figure out the maximum amount of power the transistor will dissipate. For a transistor driving a resistor, the maximum will occur at 1/2 the maximum current, with 1/2 the maximum voltage. Since the LED drops 3 volts, the maximum voltage across the resistor/transistor combination will be 2 volts, and the ... WebNov 23, 2024 · For a conventional photodiode, each absorbed photon releases one photoelectron, leading to a gain of exactly 1.0. For an avalanche photodiode, that electron is accelerated through a large voltage, which liberates additional electrons. Thus, the gain of an avalanche diode is much larger than one. The exact gain will depend on the reverse bias ...
