BC327 PNP General-Purpose Amplifier Transistor, TO-92

The BC327 fills the same PNP role as the BC557 but with a higher current rating, making it the better pick when a PNP-side switching or amplification stage needs to handle more than the BC557's modest current ceiling allows, such as driving a slightly larger relay coil or motor from the high-side rather than switching to ground. It pairs naturally with the NPN BC547 the same way the BC557 does, letting a complementary push-pull or H-bridge-style circuit be built from matched general-purpose parts rather than reaching for a dedicated power transistor when the current demand is only moderately higher than a basic small-signal part can handle.
