WebAug 3, 2024 · What is beta (β) in BJTs. In bipolar junction transistors the factor that determines the sensitivity level of the device to base current, and the amplification level at its collector is called beta or the hFE. This also … WebSep 5, 2008 · 59,588. bjt hfe. HFE is beta. It changes with each transistor even if they have the same part number because it is a range. Some transistors have a high beta and others have a low beta. See the range on the datasheet for a transistor. Beta is the current gain, not the voltage gain of a transistor. Beta is affected by the amount of current and ...
