bipolar transistor
双极(型)晶体管;［双极电晶体电路］
A semiconductor device that has a base of either a p-type or n-type material sandwiched between two masses of the opposite type of material (the collector and emitter). The two types of transistor (pnp or npn) have opposite applied voltage polarities.
一种半导体器件,有一个不是p型就是n型材料的基极,基极插在与它类型相反的两块材料 (集电极和发射极)之间。这两种类型的晶体管(pnp或npn)所需外加电压的极性刚好相反。 |
