BC857BLT1 Surface Mount PNP Silicon Transistor

BC857BLT1 is a general-purpose PNP silicon transistor with a 45 V collector-emitter rating and a 100 mA continuous collector-current rating. It uses a SOT-23 surface-mount package with base, emitter, and collector terminals. The compact package makes the device suitable for board layouts that require a discrete PNP transistor within this electrical range. Engineers should set the operating point with suitable voltage and current margin and consider the surrounding circuit’s thermal conditions during selection. The part’s PNP configuration follows the standard three-terminal bipolar transistor arrangement, keeping circuit evaluation straightforward. BC857BLT1 can be selected where its polarity, package, and published electrical limits match the existing design requirements. Request a quote for BC857BLT1.
