Tag: BD440 Pinout

Introduction The BD440 is a medium-power PNP silicon epitaxial-base transistor engineered for linear amplification and switching applications. It is part of the BD43x transistor family, serving as the PNP complement to the NPN devices such as BD439 and BD441. It is packaged in a TO-126 / SOT-32 plastic case, which supports mounting to small heatsinks […]
