| Market Reality | The 2SD882 / 2SB772 pair is the volume medium-power transistor of Chinese production: small audio amplifiers, DC-DC converters, relay and motor drivers, battery products. It is made by ST, UTC and a long list of second-source fabs, and the parts are cheap - which is exactly why two traps dominate: the SMD versions (TO-252 / DPAK) of the same part number carry a different pin order than the TO-126 through-hole body, and the wide gain spread (hFE 60-400) means a blind swap can under-drive or over-drive a stage. | The 2SD882 / 2SB772 pair is the volume medium-power transistor of Chinese production: small audio amplifiers, DC-DC converters, relay and motor drivers, battery products.
