Equivalent & Substitute Parts for BC847CQBZ

Part Overview

The Nexperia USA Inc. BC847CQBZ is an NPN bipolar junction transistor (BJT) within the Transistors, Bipolar (BJT) category. It features a 45 V collector-emitter breakdown voltage, a maximum collector current of 100 mA, 340 mW maximum power dissipation, 100 MHz transition frequency, and is provided in a 3-XDFN Exposed Pad, Wettable Flank surface-mount package (DFN1110D-3). The part is RoHS3 compliant and REACH unaffected. The product status is Obsolete. Due to this obsolescence, it is necessary to identify alternative, in-production models with matching electrical and mechanical parameters for direct substitution within existing designs.
