Dual NPN in a SOT-363 — what you get
The BC846SH6433XTMA1 is a dual NPN transistor from Infineon in a 6-VSSOP / SC-88 / SOT-363 surface-mount package. Each transistor is rated for a collector-emitter breakdown voltage of 65 V and a continuous collector current of 100 mA, with a DC current gain (hFE) minimum of 200 at 2 mA, 5 V. Transition frequency is 250 MHz, making it suitable for general-purpose switching and amplifier stages up to VHF. Maximum power dissipation is 250 mW.

65 V and 100 mA — where it fits
The 65 V VCEO and 100 mA Ic rating place this dual transistor in the medium-voltage, low-current class — typical for pre-driver stages, signal switching, and linear amplification in industrial controls, power-supply housekeeping, and automotive auxiliary circuits. The 250 MHz fT gives enough bandwidth for PWM drive up to a few MHz or small-signal RF up to VHF. The SOT-363 footprint matches many common dual-transistor layouts, so a drop-in replacement search should start with the BC846B or similar SOT-363 dual NPNs.
