BC846S

The NXP Semiconductors BC846S is an NPN general purpose double transistor designed for switching and small signal amplification applications. This component integrates two transistors within a single, very small SOT363-3 (SC-88) surface-mounted device plastic package, which helps reduce component count and board space without mutual interference between the transistors.

Key electrical characteristics include a maximum collector-emitter voltage (VCEO) of 65V and a maximum collector current (IC) of 100mA per transistor. The DC current gain (hFE) is a minimum of 110 under typical test conditions (VCE = 5V, IC = 2mA, Tamb = 25°C). The device also has a maximum collector-base voltage (VCBO) of 80V and a maximum emitter-base voltage (VEBO) of 6V.

For thermal management, the junction temperature has a maximum rating of 150°C, and the ambient temperature range is -65°C to 150°C. The total power dissipation is 220mW per transistor and 300mW per device at 25°C ambient temperature when mounted on an FR4 PCB. Thermal resistance from junction to ambient (Rth(j-a)) is 416 K/W per transistor and 230 K/W from junction to solder point.

The BC846S is supplied in a SOT363-3 package suitable for surface mounting. It is typically supplied on tape and reel in quantities of 7000 units.
