Complementary NPN/PNP in a single SOT-363
The Infineon BC846PNH6327XTSA1 combines an NPN and a PNP transistor in one PG-SOT363-PO package, saving board area in push-pull drivers, level shifters, and signal-switching stages where a matched pair is needed without two separate footprints.
Parametric boundaries for the design
Transition frequency is 250 MHz, suitable for low-frequency switching up to a few MHz and general-purpose amplification in audio or control loops. Vce saturation is 650 mV maximum at 5 mA base, 100 mA collector — the on-state voltage drop to budget in the output stage. Total power dissipation is 250 mW, which limits continuous current in the SOT-363 body; the junction temperature rating of 150 °C sets the derating curve.
