WebApr 25, 2015 · Re: Transistors and Diodes Leakage Current. « Reply #8 on: April 23, 2015, 04:45:58 pm ». There are three common specifications for collector cut-off current: Iceo = leakage from collector to emitter with base open circuit. This is the worst-case leakage, since leakage current from collector to base is amplified by the current gain. WebJun 17, 2009 · low-leakage high-voltage diode, and my answer is yes. Likely as low as 10pA, but I'd want to check specific parts. It's the same question one asks before using a transistor at extremely low collector currents. OK, not too many people use BJT transistors at 10pA, for one thing they're very slow,

WebApr 19, 2024 · BJT leakage current will be minuscule at room temperature unless the transistor has been damaged. BJT collector-emitter leakage was an issue with germanium transistors. It isn't anymore. The spec for a 2222A is 10 nanoamps max at 60 V at room temp. Noise at the input to the amp might be a problem. WebCurrent Gains in BJT: There are two types of current gain in BJT i.e. α and β. Where. I E is the emitter current; I C is the collector current; I B is the base current; Common Base …
