| Market Reality | - | The BD139 / BD140 pair is Europes bench transistor: drivers, small audio stages, series-pass elements in linear regulators and zener-boosted circuits. Production is continuous across many fabs, and the real decisions are grade and mounting: the -10 / -16 gain groups change base drive margins, the metal tab on the back is the collector (not an isolated heatsink surface), and the tempting swap to the higher-current 2SD882 quietly lowers the voltage ceiling from 80V to 30V. |
