熱敏(mǐn)參數(shù) 是衡量(liáng)晶(jīng)體管VBE，β，ICEO 等參數(shù)在常溫和高溫(wēn)下的(dí)變(biàn)化量(liáng)，是晶體管的(dí)重要特性，受(shòu)到越(yuè)來(lái)越多的鎮(zhèn)流(liú)器(qì)生產(chǎn)廠(chǎng)家重(zhòng)視。因為鎮流(liú)器內(nèi)部(bù)溫(wēn)度很(hěn)高(gāo)，高溫下晶體管的VBE，β，ICEO 等參(cān)數會(huì)發生(shēng)變化(huà)，如(rú)果變(biàn)化量過(guò)大，將(jiāng)嚴重降低產(chǎn)品可(kě)靠性。
