TIPP110/028 – TBC

The TIPP110/028 is a single-channel, silicon NPN Darlington transistor, likely manufactured in week 52 of 2006, based on the “0652” date code. The “BOURN” designation suggests a Bourns foundry or design influence, although the actual manufacturer is unspecified. The “NOT RoHS” designation indicates the component contains materials exceeding Restriction of Hazardous Substances Directive limits, specifically lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (CrVI), polybrominated biphenyls (PBB) or polybrominated diphenyl ethers (PBDE). The “3055” marking is ambiguous without further context but may refer to a lot code, internal tracking number, or potentially a related component (e.g., a 2N3055 power transistor, implying a similar application space). The TIPP110 is typically used in medium-power switching and amplifier applications requiring high current gain.
