DESCRIPTION 
 


The U430/431 are matched JFET pairs assembled in a TO-78 package. These devices offer good power gain even at frequencies beyond 250 MHz.

The TO-78 package is available with full military processing (see Military Information).

U431属于分立半导体产品 > 晶体管 - JFET。威世科技半导体制造生产的U431晶体管 - JFET结栅场效应晶体管 (JFET) 是用作电子控制开关、放大器或电压控制电阻器的器件。在栅极端子与源极端子之间施加适当极性的电势差就会增加电流流动的阻力，这意味着源极端子与漏极端子之间通道中流动的电流会更少。由于电荷流过源极与漏极端子之间的半导体通道，因此 JFET 不需要偏置电流。
