BC517 NPN Darlington 500mA 30V

Schematic .pdf 111 KB Shared

Component data for the BC517 NPN Darlington transistor, the name giving ratings of 500 mA and 30 V, catalogued under schematics as a 111 KB PDF. Expect pinout, package drawing, very high current gain figures and saturation voltage data typical of a Darlington pair in one package. It is commonly used for relay, lamp and small motor drivers, so the sheet helps when replacing a failed driver stage. Note that Darlington parts show a higher base-emitter drop on a meter, which is normal and worth remembering when testing.
