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.

2N4393屬于分立半導(dǎo)體產(chǎn)品 > 晶體管 - JFET。威世科技半導(dǎo)體制造生產(chǎn)的2N4393晶體管 - JFET結(jié)柵場(chǎng)效應(yīng)晶體管 (JFET) 是用作電子控制開(kāi)關(guān)、放大器或電壓控制電阻器的器件。在柵極端子與源極端子之間施加適當(dāng)極性的電勢(shì)差就會(huì)增加電流流動(dòng)的阻力，這意味著源極端子與漏極端子之間通道中流動(dòng)的電流會(huì)更少。由于電荷流過(guò)源極與漏極端子之間的半導(dǎo)體通道，因此 JFET 不需要偏置電流。
