Product data sheet

BC847 – SOT23 Package

Notes

• BC847 is an NPN general-purpose transistor in SOT23 (TO-236AB) package with 3 leads.
• The pinout is identical across SOT23, SOT323, and SOT416 packages (pin numbering and function are the same).
• This is the base BC847 variant (not A, B, or C). Variants differ only in DC current gain (hFE) grouping, not pinout.
• Maximum ratings: VCEO = 45 V, IC = 100 mA, Ptot = 250 mW (SOT23).
