It integrates two matched NPN devices rated for 65 V collector-emitter breakdown, 100 mA continuous collector current, and a transition frequency of 250 MHz. The dual-transistor configuration saves board space and simplifies layout for differential amplifiers, current mirrors, or signal pre-amplifier stages in industrial controls, sensor interfaces, and low-power switching circuits. Any BOM using this exact order code should be qualified against an equivalent dual NPN in SOT-363 before committing to a new build. ## Key ratings for the design decision The 65 V VCEO breakdown and 250 MHz fT suit rail-level signal conditioning and low-frequency switching. The 100 mA collector current limit and 250 mW package power dissipation cap define the load budget. ## Package and footprint reality for replacement The supplier device package is PG-SOT363-PO, which is the Infineon designation for a standard SOT-363 6-lead footprint. Any replacement must match the SOT-363 land pattern.","metaTitle":"BC846SE6433BTMA1 Dual NPN Transistor, 65V, 250MHz, SOT-363","metaDescription":"BC846SE6433BTMA1 dual NPN transistor in SOT-363. 65V VCEO, 250MHz fT, 100mA Ic.
