2N4391分立半导体产品的晶体管-JFET规格书PDF中文资料

2N4391属于分立半导体产品的晶体管-JFET。由威世制造生产的2N4391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。

DESCRIPTION

The 2N/PN/SST4391 series features many of the superior characteristics of JFETs which make it a good choice for demanding analog switching applications and for specialized amplifier circuits.

The 2N series hermetically-sealed TO-206AA (TO-18) can is available with processing per MIL-S-19500 (see Military Information). Both the PN, TO-226AA (TO-92), and SST, TO-236 (SOT-23), series are available in tape-and-reel for automated assembly (see Packaging Information). For similar dual products, see the 2N5564/5565/5566 data sheet.
