It handles a collector current up to 500 mA and a collector-emitter breakdown voltage of 45 V, with a transition frequency of 170 MHz. The 330 mW power dissipation limit suits low-to-moderate drive stages, signal amplification, and load switching on compact boards. ## Key ratings for the BOM decision The 45 V VCEO rating covers most industrial and telecom supply buses. The 500 mA continuous collector current handles relay coils, small solenoids, and LED strings without needing a heat sink at room ambient. ## Package and reflow considerations The SOT-23 (PG-SOT23) footprint is standard — three leads. No exposed pad, so the 330 mW dissipation limit is the junction-to-ambient ceiling. ## Obsolete — sourcing reality Infineon lists the BC 817-16 E6327 as obsolete.","metaTitle":"BC 817-16 E6327 NPN Transistor, 45 V, 500 mA, SOT-23","metaDescription":"Infineon BC 817-16 E6327 NPN transistor: 45 V VCEO, 500 mA Ic, 170 MHz fT, 330 mW, SOT-23.

The BC 817 base number remains active in other gain-group variants (e.g., BC 817-25), but those differ in hFE binning.
