WebSi es necesario usar un transistor con una ganancia de corriente aproximada para ensamblar un circuito eléctrico, un probador puede determinar el elemento requerido. Para ello, el comprobador se cambia al modo hFE. El transistor está conectado al conector apropiado para el tipo específico de dispositivo ubicado en el dispositivo. Web30 Jun 2009 · But the hFE is a wide range and could be as low as 20 when its VCE is 1V and its collector current is 0.1mA. Design your circuit so it still works properly when the hFE of the transistor is 20 to 300 and the collector voltage and current is whatever you need.
