Understanding the FTD02P Transistor: Datasheet, Specifications, and Applications
The most common drop-in replacement for the FTD02P is the PEL-TT3043 (often shortened to TT3043 ). The complimentary replacement for its partner, the FTD01N, is the PEL-TT3034 (TT3034) . FTD01N and FTD02P Electronic Components - Alibaba
The Ftd02p may be small, but its datasheet is mighty. Use it well.
