Infineon lists the BC 856BW H6327 as obsolete.
The 65 V collector-emitter breakdown voltage gives headroom for 24 V and 48 V industrial rails, with derating margin. The 250 MHz transition frequency means it can handle switching up into the VHF range — useful for oscillator and buffer stages in RF front-ends, not just low-speed general-purpose switching. DC current gain of 220 minimum at 2 mA collector current ensures consistent amplification in analog signal paths, such as preamp stages in audio or sensor conditioning circuits. The 15 nA maximum collector cutoff current keeps leakage low in high-impedance nodes. Maximum power dissipation of 250 mW sets the thermal budget. In a SOT-323 package on a standard FR4 board, that translates to roughly 200 mW usable at 70°C ambient before derating — enough for small-signal stages but not output drivers.
Supplied in Tape & Reel, the BC 856BW H6327 comes in the SC-70 / SOT-323 case (Infineon designates it PG-SOT323). This is a three-lead surface-mount package with 1.3 mm pitch, commonly used for small-signal discretes in compact designs. The base footprint is shared across the BC 856x family, so a layout done for this part can accept other SOT-323 PNP transistors without board changes.
